In previous blogs we learned that dry eyes is a problem that affects many people. We also learned that a course of products can be used to relieve dry eyes. Lastly, the Blephex machine can easily get rid of the bacteria which produces exotoxins that stop the formation of healthy tears which ultimately cause dry eye.
In this final blog of our dry eye series we will focus on the Scleral Lens, which is very beneficial in combatting severe dry eye. This lens is larger and more rigid compared to the conventional contact lens. Its unique formation covers the entire cornea which prevent it from moving out of place when the wearer blinks. One of the most significant benefits of this specialized lens is its ability to combat dry eye. This is due to its unique shape, which creates extra space between the back of the contact lens and the cornea. This space which acts as a reservoir for saline solution is extremely important in preventing dry eye.
Another important benefit of the Scleral Lens is that it is helpful in treating people with a progressive eye disease called Keratoconus. Although this condition occurs mostly with young adults, it has been found in people of all ages. Keratoconus affects one or both eyes by thinning and weakening the cornea. This thinning makes it flimsy and creates a bulge or a cone shape. This irregular formation causes nearsightedness and irregular astigmatism to develop, and eventually without treatment, distorted blurred vision and glare and light sensitivity will occur. The unique shape of the Scleral lens accommodates the sufferers of Keratoconus by providing a uniform surface like that of a healthy normal cornea. Keratoconus is hereditary, so if a family member has it, you are advised to have your eyes checked out as soon as possible.
Scleral Lens technology is advancing rapidly and manufacturers are designing them to correct more vision problems than ever before. Our doctors at our Finch and St. Clair offices will be more than happy to explain the benefits of these lenses. Come in and inquire about the Scleral lens the next time you’re here for a visit.
