For example, you may notice that things begin to get blurry, or you have trouble seeing objects in the distance. For those with Keratoconus, a condition that occurs when the cornea in the eye begins to thin and becomes cone-shaped, distorted vision and sensitivity to light may arise. How can this be treated? Luckily, Keratoconus inserts can be used to treat patients with the condition, and a study in the October 2005 issue of Archives of Ophthalmology resulted in nearly half of participants achieving 20/40 uncorrected vision or better.
