Keratoconus is a disease that causes the cornea, which is normally round, to thin and bulge into a cone shape. This altered shape creates distortions in the vision. To treat this, a corneal cross-linking procedure may be done. Corneal cross-linking, also sometimes referred to as CXL, is an in-office, outpatient procedure that helps to correct and strengthen the cornea after it has been affected by keratoconus.
What Is Corneal Cross-Linking, and How Is It Performed?
A corneal cross-linking procedure involves creating links between the collagen fibres in the cornea. It is done in two steps. The first involves applying liquid riboflavin to the eye’s surface followed by exposure to a UV light. This procedure is minimally invasive and is done ... Read More
The Laser is Hot –The lasers used to perform eye surgery are cold. You may have heard or been told that there is a burning smell during the procedure as well. This is caused by the laser releasing carbon atoms and is not something to worry about.
The Procedure is Painful – You will be given anesthetic drops before the procedure, so you often won’t feel anything. In the days following surgery, you may feel some discomfort, but it will pass as your eyes heal.

Shortsightedness, also known as myopia, is one of the most common refractive errors. It happens from a combination of both genetic and environmental factors affecting the normal growth of the eye, causing it to become longer than average or result in a steep curvature of the cornea.
In the eye of a shortsighted person, light entering doesn’t focus on the retina, but instead in front of it, making objects further away appear blurry and not focused. Approximately 30% of Canadians are affected by myopia to some extent, whether mildly or seriously. The rate is increasing however with the use of modern technology. Some vision experts claim that all the time people spend looking at cell phones and computer screens at ... Read More
