Complications Associated With Laser Eye Surgery
There are risks associated with any kind of surgery and laser eye surgery is no exception. There are several, possible, laser eye surgery complications.
In most cases where laser eye surgery has been performed, the cornea tries to return to its original state but stabilizes within a few months. Because of this, over-correction is necessary, initially. Though it is uncommon, over-correction can be one of the permanent laser eye surgery complications in which you would need glasses for reading and other such work done close to the eyes.
Since the density and composition of the tissue to be removed can vary, it is possible to encounter another laser eye surgery complication, under-correction. There are several factors that may lead to this problem, one being the aforementioned tendency of the cornea to return to its original state. Re-treatment is usually an option if this occurs.
If there is a lot of eye movement during the procedure, or if the laser is not centered correctly, the complication can be a decentered ablation. This can result in irregular astigmatism, optical aberrations, starbursts, or contrast sensitivity.
Nighttime glare can be one of the more serious laser eye surgery complications. At night, pupils dilate and if the optical zone is smaller than the dilated pupil then nighttime glare can occur. This can be serious because it may result in the person having to stop driving at night.
Of course there are other possible laser eye surgery complications. Just be sure to talk to your doctor about all the possibilities and worse case scenarios before making the decision to take this step in vision correction.
