Corneal crosslinking is a completely blade-free procedure now available at Southern Eye Center for the treatment of irregular astigmatism. This exciting new procedure works to strengthen and stabilize the cornea, halting further corneal changes and possibly improving uncorrected vision.
Irregular Astigmatism occurs due to an asymmetrical distortion of the normal curvature of the cornea – the clear part of the eye in front of the iris and pupil. This distortion may be caused by Keratoconus [phonetic], a condition that occurs when the shape of the cornea changes to a pointed, conical shape. Irregular astigmatism may also be due to Pellucid Marginal Degeneration or PMD, a condition caused by a weakness in the lower part of the cornea, resulting in a droop in the corneal surface.
During the crosslinking procedure, the patient is awake but mildly sedated, and the eye is numbed. Riboflavin drops are applied to the eye’s surface (the cornea). An ultraviolet light is focused onto the cornea, which works with the riboflavin on a microscopic level to strengthen the cornea. Ultimately this means the cornea’s shape can be strengthened and stabilized, allowing for better vision! Your vision may be worse right after the procedure – this is normal and usually, within three to six weeks, vision improvement occurs.
