Ketatoconus lenses that are comfortable
Today I would like to talk a little about a condition known as keratoconus. This condition is one in which the cornea slowly thins and starts forming a cone shape. The result optically is considerable. Early on large astigmatic changes start occurring and in advanced cases spectacles can no longer correct for the aberrations that occur. Rigid gas permeable lenses or RGP lenses have been our only option up till recently (with the exception of a corneal transplant) that will keep this condition in check and allow the individual to function with clear vision. There are special RGP lenses that are made for mid to advanced cases of this condition. These have worked well for many years but can sometimes be somewhat uncomfortable for some people. About 3 or 4 years ago a new company called Synergeyes came out with a new hybrid lens for this condition. This lens has an RGP center and a soft lens skirt. The end result is that the lens stays more stable on some of these advanced keratoconus eyes and is quite a bit more comfortable than a standard RGP lens. Patients have loved this newer lens and are quite happy with this new addition to our treatment options. If you are a keratoconus patient out there, I urge you to go to your doctor and ask about the synergeyes lens for keratoconus. I am sure you will be glad that you did.
