Unsurpassed Technology to Deliver Custom Vision and Comfort
Here is how we do it AT Eyes of nM
You should not have to wear uncomfortable contact lenses to enjoy good vision.
The Oculus Pentacam allows us to take multiple images of the cornea. We are able to see the front of the cornea, the back of the cornea, the overall corneal thickness and the elevation of the cornea. This allows for early diagnosis of many corneal conditions including keratoconus.
The Pentacam also allows us to take data on the sclera, the white part of the eye. This is a picture of the CSP data collected that gives us information out to 17mm onto the eye. Knowing the shape of the eye allows the scleral lens to sit comfortably on the each individual eye
From these maps we use a software called Wave to design the lenses. Each lens is completely customized for the individual. This technology is utilized for the majority of our RGP and scleral lenses to give our patients the best experience.
So What Are Scleral Contact Lenses?
Scleral contact lenses are are larger diameter rigid gas permeable (RGP) contact lenses. Scleral lenses sit on the sclera (the white part of the eye) and the center of the lens vaults over the cornea, leaving the cornea untouched.
Who is a Good Candidate for Scleral Contact Lenses?
Scleral contact lenses could potentially be used for anyone. They are particularly helpful for patients with Keratoconus, pellucid degeneration, post-LASIK / RK / PRK, corneal transplants, Dry Eye Syndrome, Sjogren’s Syndrome, Graft vs. Host disease, Stevens-Johnson Syndrome, Microphthalmia, Corneal Ectasia, Neurotrophic Keratopathy and patients who have had injuries or chemical burns. People who suffer from lagophthalmos (cannot close their eyes all the way) can have tremendous benefit from scleral lenses as well. People who have high astigmatism and have not done well in soft lenses also do very well with these lenses.
Are Scleral Lenses Comfortable?
Depending how well the scleral lens fits on each individual eye the lenses can be really comfortable or not. A poor fitting lens can often lead to mid day fogging, lens feeling tight by the end of the day, red eyes when the lens is removed or the patient may get limited wear time out of their lenses. A well fit lens should give good comfort throughout the day, no fogging, and maximized vision. Because the comfort of the lens is so dependent on the fit, having the measurements of the sclera out to 17 mm ensures that our lenses should sit where it needs to on the patients eye for maximum comfort.
