LASIK May Ruin Your Sight As You Age
December 14, 2006
A new study has raised concerns regarding the long-term effects of laser eye surgery. New research indicates that laser surgery for short-sightedness can cause haze, glare and blurred vision as people reach their senior years.
Laser surgery for short-sightedness flattens the central cornea, which provides better eyesight, but can seriously affect the movement of corneal cells.
Normally, these cells start on the outsides of the eye and migrate toward the center. When they meet, they create pigment, which scatters light and can cause haze and blur. This occurs just below the pupil, in an area called the Hudson-Stahli Line.
The laser surgery causes these cells to move at a different rate down the flattened cornea. They meet in front of the pupil, intensifying the haze.
At present, the problem cannot be fixed.
