In this video, there is something called a corneal gas permeable lens, and as you can see, the contact lens fits inside the iris contours or the cornea.
So, it doesn't extend all the way out to the colored part of the eye, making it actually smaller when compared to a soft contact lens or any other type of lens.
What is being observed is the stability of the lens, its centeredness, and the movement ensuring it gets fresh tears and oxygen underneath.
The focus is on the lens-to-cornea relationship, checking for any areas that might be too tight, too loose, too flat, or too steep.
These types of lenses are very useful. Many patients in the clinic wear them, especially those with severe keratoconus or any sort of irregular astigmatism.
They also work well for patients with regular astigmatism.
So, this is a unique type of contact lens that is fitted in our office and is really helpful for various conditions.
