Corneal refractive therapy, also known as CRT, is a simple, painless treatment for refractive eye errors like myopia and has two core benefits. First, it can be used to help patients see clearly during the day without using glasses or contact lenses, giving them the freedom and flexibility that they need to live life to the fullest. Second, CRT has been shown to help slow the progression of myopia, keeping prescriptions under control and potentially reducing the likelihood of patients developing serious eye health problems associated with high myopia in the future.
Here’s everything that you need to know about corneal refractive therapy and what it means for you.
Refractive eye problems like nearsightedness, farsightedness and astigmatism are extremely common, with nearsightedness – also known as myopia – being the most common of all. Patients with myopia can see nearby objects clearly, but those further away become progressively more blurred. Refractive eye errors occur when the shape of the clear dome covering the front part of the eye, called the cornea, impair the light-bending and focusing process in your eyes. This leads to the light ending up in the wrong place inside the eye, and the message that is sent to our brain from our eyes is muddled, causing blurred vision.
Corneal refractive therapy was initially developed as a treatment to correct and slow the progression of nearsightedness. However, it has also been found to be effective at controlling other refractive errors, including farsightedness, astigmatism and an age-related refractive condition called presbyopia.
CRT is a non-invasive, painless and straightforward method of correcting patient vision so that they don’t need to wear contacts or glasses, and they don’t need laser vision correction surgery to see clearly. CRT uses special contact lenses that are worn overnight and apply light pressure to the cornea in order to reshape it so that light is refracted correctly, and the image sent from the eyes to the brain is clear. The cornea is able to retain this new shape even after the contact lenses are removed the next morning, meaning that you can continue to see clearly for several hours. The more consistently you wear your CRT lenses overnight, the longer your eyes will learn to retain their new shape and eventually, patients can enjoy up to 48 hours of clear vision without using prescription lenses. However, the effects aren’t permanent so if you stop wearing the lenses, your vision will gradually return back to normal over the course of a few days.
Another key benefit of CRT is that it can actually help to slow the progression of myopia. Most people who are nearsighted find that their eyesight gets progressively worse as they get older. This deterioration may not be rapid, but it can end in patients requiring high prescriptions. Studies have found that patients who have high myopia are more likely to develop serious eye problems in the future, including glaucoma, macular degeneration, cataracts and a detached retina. Regular use of your corneal refractive therapy lenses could help keep your prescription stable and lower your risk of developing these problems.
You may be a candidate for corneal refractive therapy if you:
Have a myopia prescription within specific parameters
Have a prescription for hyperopia, presbyopia or astigmatism within specific parameters
Have stable vision, which means that your prescription hasn’t changed during the last two years
Are not a suitable candidate for laser vision correction
Have a job that makes it impractical or unsafe to wear glasses or contact lenses
Enjoy hobbies that make it impractical or unsafe to wear glasses or contact lenses
Have healthy eyes and are generally in good health

Every patient is different and so are their eyes. This means that there need to be different types of contact lenses to suit each individual. Some patients have corneal abnormalities which mean that conventional lenses won’t sit comfortably on the surface of their eyes, while others suffer from eye conditions that mean normal contact lenses won’t be comfortable or could irritate their eyes.
As you may have guessed from the name, specialty contact lenses are unconventional contacts that are designed for patients that regular contacts might not be suitable. Here are some of the main types of speciality contact lenses and who they are recommended for.
Some of the patients that might benefit from specialty contact lenses include those who:
have been diagnosed with dry eye syndrome
have corneal scarring
have been diagnosed with keratoconus, a condition characterized by the bulging of the cornea
suffer from strabismus, a condition where the patient has an eye that turns in or out relative to the other
have suffered an injury to the eye
suffer from a peripheral corneal thinning disorder
are intolerant to other types of lenses
Your eye doctor or contact lens provider will be able to tell you if you need specialty contact lenses and if so, which lenses would be best based on your individual requirements.
Also known as RGP lenses, these are made from a special material that allows oxygen to pass through them and reach the surface of the eyes. This helps to keep the eyes hydrated and comfortable, making these lenses easier to wear, especially for patients who suffer from dry eyes. Dry eyes aren’t just a symptom, but a very real condition, characterized by dry, stiff, and uncomfortable eyes, blurred vision, and eye fatigue. RGP lenses are more rigid than soft lenses, and this helps to keep them stable and secure on the eyes so that patients can enjoy sharper vision. They also help the cornea to maintain its shape, which helps to minimize the effects of some corneal abnormalities.
Scleral contact lenses are very different to standard contact lenses. This is because scleral lenses are much larger in diameter, with three different sizes available depending on your specific needs. This size difference means that the edges of the contact lens fall on a white part of the eye, called the sclera rather than the cornea. Scleral lenses are also different in that they vault over the surface of the cornea rather than touching it, leaving a space between the front surface of the eye and the back of the contact lens. This makes scleral lenses a good choice for patients with dry eyes and corneal abnormalities. Space can trap tear film which keeps the eyes hydrated, while space also accommodates many corneal abnormalities, such as the bulge associated with keratoconus.
Limbal contact lenses are another type of specialty lens that falls between rigid gas-permeable lenses and scleral varieties in terms of their size. Their larger overall diameter helps to increase their stability on the surface of your eyes. They also offer minimal interference with the eyelids, which helps to ensure comfort and clarity of your vision.
Hybrid contact lenses are a combination of both soft and gas-permeable contact lenses, giving patients the opportunity to enjoy the best parts of both designs. The middle part of hybrid lenses is made from gas-permeable material that lets oxygen pass through to the eyes. However, the gas-permeable part of the lens is more rigid, and this firmer center gives the lens greater stability and the patient enhanced clarity. The RGP portion of the lens also helps to trap a tear film between the cornea and the lens so that the eye remains hydrated. Meanwhile, the outer edge of hybrid lenses is a soft lens skirt. This means that patients don’t have to deal with the hard edges associated with RGP lenses that may be uncomfortable. Instead, the comfort levels that patients experience are more like wearing fully soft lenses.

Whether people like it or not, fine lines and wrinkles go hand in hand with the aging process. However, they typically appear sooner and look worse for those who spend time in the sun. Fortunately, TempSure Envi offers a solution that improves the skin’s appearance and health.
Instead of having invasive surgery, experts in the field of aesthetics can offer their patients something better. Not only is TempSure Envi non-invasive, but it’s also safe and effective. Simply put, it provides optimal improvement without any pain or discomfort.
Eliminating fine lines and wrinkles is just one of many benefits associated with TempSure Envi treatments. This same treatment works incredibly well to reduce the appearance of cellulite. Overall, it smooths skin, making it look more youthful.
However, even leading ophthalmologists and optometrists rely on TempSure Envi to treat patients with dry eye disease. Usually caused by Meibomian Gland Disease or MGD, the combination often makes a person look tired. In addition to dealing with uncomfortable symptoms, this causes bags to form beneath the eyes.
Because TempSure Envi is a gentle and safe treatment, it’s ideal for giving people with dry eye disease from MGD a fresher appearance.
This treatment uses a radiofrequency that gently and safely heats the skin for a specific amount of time. The body naturally reacts by producing new collagen. Because the new fibers are tighter and denser, they fill in voids in the form of lines, wrinkles, and cellulite. It also diminishes bagginess associated with dry eye disease from MGD.
Experts in the field of aesthetics can use TempSure Envi on many different parts of the body. At the same time, optometrists can use it on patients with dry eye disease.
Most people notice an improvement after just one session. Initially, their skin looks more toned and feels tighter. With each treatment, new collagen will continue to grow. To achieve optimal results, most individuals need at least four sessions.
Additionally, the Food and Drug Administration (FDA) approved TempSure Envi as a viable treatment for all the reasons mentioned. Specifically, it stated that even as a non-invasive solution, TempSure Envi is capable of rejuvenating a person’s appearance, and with no downtime.
Keep in mind that everyone responds somewhat differently. It may take a few more sessions to see desired results. However, most enjoy tighter and more youthful-looking skin for about six months after just four sessions.
To maintain their appearance and continue the cycle of collagen growth, people can have additional TempSure Envi treatments done without any problem. Usually, people have much the same experience. That consists of redness that appears in roughly a day or two. However, it goes away quickly.
TempSure Envi is an FDA-approved and non-invasive treatment that helps people achieve tighter and more toned skin. Additionally, it doesn’t cause any real side effects, and it doesn’t involve any recovery time. Many individuals who opt for this treatment can have it done during their lunch break and return to work with better looking skin appearance.
Thanks to the advancement of lens technology, glasses lenses are no longer a single, one size fits all solution. There are a variety of different lens types that can be used in glasses, giving patients greater flexibility and control over their vision than ever before.
Also known as monovision lenses, these lenses are designed to correct the wearer’s vision at just one distance, and have a single prescription covering the entire surface of the lens. They are most often recommended for people who are either nearsighted (myopia) or farsighted (hyperopia) and who need glasses for a specific activity, such as driving or reading.
Progressive lenses are multifocal lenses that can correct a patient’s vision at different working distances, ranging from far distance to reading distance. However, rather than designating different areas on the lenses for different distances with visible lines separating them, progressive lenses have a gradual change so that the wearer can smoothly transition from one lens power to another.
As you may have guessed from the name, bifocal and trifocal lenses have either two or three lens powers depending on which type you choose. Bifocal lenses support distance vision in the top half of the lens, and near vision in the lower half. Trifocal lenses support distance vision in the top third of the lens, intermediate vision in the middle segment and near vision in the bottom third. Whichever variety you choose, you will see visible lines separating each segment.
Bifocal and trifocal lenses are recommended for patients who are near or farsighted, and those who develop presbyopia, which is the natural hardening of the eye lens, that occurs as we get older. Presbyopia makes it harder for the lens of the eye to adapt to focus at different distances.
Multifocal lenses are the alternative name given to bifocal, trifocal and progressive lenses.
Computer lenses are prescription lenses that are specifically designed to be worn when doing computer work. This is because they place the optimum lens power for viewing your computer screen exactly where you need it – which is closer than intermediate vision, but further away than reading material is usually held. Wearing computer lenses can significantly reduce the negative effects caused by the high visual demands of computer work, including blurred vision, redness, dry eyes, double vision and dizziness.
Also known as photochromic lenses, transition lenses are a special type of lens that darken when in the sunlight and lighten when in softer light or the dark. This versatility gives the wearer the convenience of being able to move between different environments without needing to change their glasses. This makes them extremely cost effective and prevent the wearer from needing to take multiple pairs of glasses out with them. Transition lenses also filter out many of the harmful UV rays that are emitted from the sun, helping to keep eyes healthy too. They are ideal for people who spend a lot of time going between inside and outside, or who work outside in varying weather conditions.
Blue light lenses are specially crafted lenses that contain filters that block out much of the artificial blue light that is produced by digital devices like computers, smartphones and tablets. Natural blue light is actually good for balancing our sleep-wake cycle, boosting our mood and enhancing our cognitive abilities so that we can function better day to day. However, too much blue light, especially from artificial sources, can have the opposite effect. Many people who fail to use blue light lenses can go on to develop digital eye strain, which produces symptoms like eye fatigue, dry eyes, blurred vision, headaches and more. Blue light lenses are recommended for anyone who spends a lot of time working on a digital device.
Polarized lenses are used to reduce eyestrain and improve the quality of vision in patients on especially sunny days, making them ideal for anyone who spends a lot of time outdoors. They can do this because they have a special filter that blocks some of the light from passing through the lens. Vertical light is allowed to pass through, while horizontal light, such as that which bounces off of water and can be blinding, is blocked. Polarized lenses are most often used in sunglasses since they are worn outdoors, and the wearer also needs to protect their eyes from UV damage.

Neurolens are the first and only prescription lenses that include an element of contoured prism in their design. This prism is designed to bring the patient’s eyes into more equal alignment, and this should help to provide relief from the symptoms that are associated with several eye misalignment conditions, including digital eye strain and binocular vision dysfunction.
Digital eye strain is the name given to describe a group of symptoms that can occur when someone spends long periods of time using digital devices. Since using digital devices requires the eyes to work harder than normal and we don’t always position our devices the perfect distance away, it can lead to issues such as eye pain, dry and irritated eyes, eye fatigue, light sensitivity and blurred vision. Unsurprisingly, the number of people who are experiencing digital eye strain has grown significantly over the last few years and is expected to continue to do so.
Binocular vision dysfunction, also known as BVD for short, is another eye condition but is one that is very misunderstood. Binocular vision dysfunction occurs when the eyes aren’t perfectly aligned, causing your brain and eyes to work harder than normal in order to create a clear visual image and remain focused. This places pressure on the trigeminal nerve, which is the nerve that is responsible for the majority of the sensations that we experience in our head and back. BVD can often manifest as other things owing to the huge range of symptoms that are associated with the condition. These can include, but aren’t limited to:
Many people don’t think to visit an eye doctor when they are experiencing these symptoms, but all can occur simply because the eyes are out of alignment.
As well as containing your usual prescription, Neurolens lenses also contain a specific amount of contoured micro-prism. This micro-prism alters the position of images so that they are aligned in the same plane. This then reduces the pressure on the muscles around the eyes as well as bringing the eyes into alignment, easing the symptoms that the patient has been experiencing.
The amount of prism in Neurolens lenses is decided using the Neurolens eye-tracking device. This non-invasively measures the misalignment that the patient is experiencing, and this is used to form the basis for the patient’s Neurolens prescription. After this, it’s fairly normal for the amount of prism to need to be adjusted by infinitesimal amounts to achieve the optimal relief from your symptoms. Most patients who choose Neurolens treatment see a 50% improvement in their vision as soon as they start to have micro-prism incorporated into their prescription lenses. However, with careful adjustments, many patients see as much as an 80% reduction in the effects of digital eye strain and binocular vision dysfunction.

If you find it difficult to tell colors apart, you may be color blind. Color blindness, or color deficiency, is estimated to affect around 8% of men and about 1% of women, but for those affected, it can significantly impact the quality of their day-to-day life. Contrary to popular belief, being color blind doesn’t mean that you can’t see any color at all. Instead, patients simply struggle to differentiate between certain colors. The vast majority of people who are color blind find it impossible to tell the difference between varying shades of red and green. You may hear this referred to as red-green color deficiency. However, this doesn’t only mean that they mix up red and green. They can also mix up colors that have some green or red light as part of their whole colors, for example purple and blue. This is because they are unable to see the red light that forms part of the color purple.
As you can probably imagine, this type of visual impairment can be a problem for things like traffic lights, taking medications and even looking at signs and directions. For example, someone who is color blind may find that the green on a traffic light may appear white or even blue.
EnChroma lens technology is specifically designed to counteract red-green color deficiency and enable patients to better identify the difference in these colors or shades. They do this by selectively filtering out the red and green wavelengths of light at the exact point where the color sensitivities overlap before hitting the retina, creating far greater contrast between the colors so that the patient can distinguish between them successfully. Most cases of color blindness respond well to EnChroma’s innovative spectral lens technology, giving patients the ability to experience life in bright, vibrant technicolor.
EnChroma lenses are made from leading edge, Trivex material, and this helps to give them the best possible quality and clarity of vision. These lenses are also extremely light, strong and offer patients 100% protection against UV light, helping to keep your eyes healthy as well as improving your vision.
If you or someone you know is color blind or color deficient and could benefit from EnChroma lenses, contact us today to learn more about how they can help!
Optomap is an innovative new technology that gives eye doctors the ability to perform ultra-wide retinal imaging that is far superior to what can currently be achieved using conventional retinal imaging options. In contrast to conventional retinal imaging, Optomap captures at least 50% more of the retina in a single capture, and with Optomap’s multi-capture function, up to 97% of the retina can be viewed. This gives eye care professionals greater opportunity to monitor the health and condition of patient vision.
Optomap is another great preventative eyecare technology tool. By allowing your eye doctor to have a comprehensive view of your retina, they will be able to detect any developing eye diseases early on, before they have a detrimental impact on your vision and day to day life. Not only can Optomap detect eye conditions such as retinal holes, retinal detachment, macular degeneration and diabetic retinopathy, but it can also be used to identify some general health conditions such as cardiovascular disease, stroke and cancer.
Optomap is a fast, painless and non-invasive procedure that is suitable for patients of all ages, even children and pregnant women. Many patients require their eyes to be dilated ahead of the scan and will be given eyedrops which will widen their pupils and make it easier for the camera to see the structures inside the eye. Pupil dilation is painless, but patients may feel more sensitive to light both during their Optomap scan and afterwards for up to 24 hours. You may also have slightly blurred vision for a few hours. Once your eyes are dilated, you’ll be sat down and asked to look into a small device that will take the pictures of your retina. A short flash of light will let you know that the image has been taken, and the entire imaging is over in just a few seconds. The results will be sent digitally to your eye doctor who will then evaluate them. The results will also be stored on your personal optical record for future information.
If you would like more information about what is involved in Optomap, or to schedule an appointment for this effective screening technology, please contact our eyecare team.
Eye care professionals use Optikam’s technology to capture more than 3 million eyewear measurements every year. The OptikamPad iPad app is a total dispensing solution that enables eye care professionals to successfully assist patients at all stages of the eyewear dispensing process, providing them with a unique and custom patient experience.
You may be surprised to learn that wearing glasses can and likely will affect your posture. Glasses lenses are most accurate when you look directly through their center. This means if your glasses are sitting too low or have slipped down your nose, you may find that you are subconsciously tilting your head back and this can affect your overall posture.
Optikam’s OPD measurement device is a cutting-edge tool that obtains eyewear measurements that take into account how the frame will be worn by patients, enabling the fit to be customized to their individual parameters. The ten measurements taken into account when determining each patient’s position of wear include:
Monocular pupillary distance
Multifocal seg heights
Rear vertex distance
Wrap (face form tilt)
Near pupillary distance
This results in frames that not only look fantastic, but that also fit perfectly, remaining both comfortable and stable on the face without you needing to adopt an unnatural posture. The measurements obtained by the Optikam OPD measurement tool are immediately visible on your eye doctor’s tablet so that they can recommend which alterations to the frames are needed to ensure that the frames fit with precision and gives you the best visual experience.
Traditionally, the process of a comprehensive eye exam, choosing frames and fitting glasses requires fairly close contact with your eye doctor or other eye care professionals. However, with social distancing being a new process variable, many patients are looking for more virtual options. Fortunately, OptikamPad makes it possible for optical stores to dispense eyeglasses with minimal human contact. This is because the OptikamPad can take measurements from a further distance or even through plexiglass screens. It can even be placed on a stand and the app operated using a Bluetooth mouse, putting even greater distance between your eye care professional and you.
If you would like to find out more about Optikam OPD and OptikamPad, our knowledgeable team would be delighted to help. Please contact us with any questions or to schedule an appointment.
Our eyes are extremely delicate, yet they can be subjected to harsh conditions and other environmental factors that affect their health. One of the problems that can affect our eyes is an accumulation of dirt, debris and bacteria on the eyelids. This can cause a range of issues, including stopping tear film from reaching the eyes and being properly dispersed over their surface – which is necessary to keep them healthy and comfortable. Fortunately, a new solution called BlephexÔ can help.
BlephexÔ is a handheld electro-mechanical device that is applied to the margins of the eyelids with the purpose of cleaning them and improving the effectiveness with which tear film flows onto the surface of the eyes.
BlephexÔ has a disposable, surgical-grade sponge tip which rapidly oscillates to create a cleaning action. Before the sponge tip is placed onto the eyes, it is soaked in a gentle exfoliating solution. This solution provides soft abrasion to help remove dead skin cells and debris that could be irritating the eyes and interrupting tear film progression. The BlephexÔ device is manually applied to the eyes and moved gently across the eyelids, with the entire, painless process taking approximately 6 to 8 minutes per eye. A different sponge is used on each eye, ensuring that no bacteria is passed between them. After the procedure, patients are given instructions on how to maintain the cleanliness of their eyelids with daily/nightly eyelid hygiene at home.
Most patients experience a significant improvement in tear film production and dispersal, and a reduction in unpleasant symptoms that they may have been experiencing within 48 hours of their treatment. While a single treatment is normally enough to produce excellent results, many patients are advised to have BlephexÔ every 4-6 months.
BlephexÔ can be used to clean the eyelids at any time, and people who suffer from dry eyes or eye allergies may find it is particularly beneficial for helping to reduce the symptoms that they experience. It can also be combined with Lipiflow – another technological solution – to help counteract the effects of dry eyes.
Unsurprisingly, BlephexÔ is particularly recommended as a treatment for an eye condition called blepharitis. Blepharitis is characterized by the inflammation of the eyelids, which causes them to become red, swollen and itchy. Although the condition is not usually serious, it can lead to further problems if it isn’t treated.
Symptoms of blepharitis include:
A gritty, irritated feeling affecting the eyes
Flakes or crustiness around the roots of the eyelashes
Eyelids that stick together when you wake up in the morning
If you are suffering from the symptoms of blepharitis, dry eyes or eye allergies and feel that you would benefit from BlephexÔ treatment, please contact our team to schedule a consultation appointment.
Visual field testing is an important part of most standard comprehensive eye exams. Also sometimes known as perimetry testing, Visual field testing is a method to measure the entire scope of vision of an individual, including their peripheral/side vision.
Visual field testing is one of the most effective diagnostic treatments in the detection of glaucoma. This is because when patients are affected by glaucoma, it is usually the peripheral vision that is affected by their condition first. However, it can also be used to detect central or peripheral retinal diseases, eyelid conditions such as drooping, optic nerve damage and conditions that affect the visual pathways from the optic nerve to the area of the brain where this information is processed into vision.
Visual field testing is also an important part of monitoring for people who are considered to be at risk for vision loss from disease and other problems, including those who have been diagnosed with the following:
Pituitary gland disorders
Central nervous system problems (such as a tumor that may be pressing on the brain)
High blood pressure
There are a variety of methods that can be used to perform visual field testing, including:
Static automated perimetry. This is where a machine is used to quantify how well the patient is able to detect flashing lights of varying size and brightness in different areas of their visual field, while they concentrate on a central point. The patient responds by pushing a button when they see the light.
Kinetic perimetry. This involves points of light that are fixed in size and intensity and are presented along the patient’s peripheral vision, before being gradually moved inwards to determine their field of vision.
Visual field testing is non-invasive, painless and doesn’t require patients to have their eyes dilated. The results, which are usually presented in a series of charts, are digital and sent directly to your eye doctor for interpretation. Depending on the outcome of your results, you may be recommended for further diagnostic testing which could include blood tests. If you have been diagnosed with glaucoma, you will probably be recommended to have several visual field tests each year, which will help your eye doctor to monitor the progression of your condition and recommend treatments to slow it.
If you would like more information about visual field testing, or if you have concerns about your peripheral vision, please don’t hesitate to schedule an appointment with our experienced and knowledgeable eyecare team today.
