PRK over Keratoconus with Haze
These are 2 photos taken of the same eye through a slit lamp (special microscope) with differing magnifications. This eye has keratoconus. In an effort to make this cornea more spherical, PRK surgery was done several years prior to the time this photo was taken. One of the risk factors of PRK surgery is corneal hazing. Note the cloudy area opposite the pupil. This haze is permanent and has caused a reduction in the best corrected vision in this eye. Before the PRK was done, this eye was corrected to 20/20 with a contact lens. Now the best corrected visual acuity is about 20/40, also with a contact lens. The point of my posting these photos is to warn you of the risk of additional complications from this elective procedure.
