When a patient presents with high eye pressure, what we are usually concerned about is the risk of glaucoma. Glaucoma is an eye condition that causes damage to the nerve at the back of the eye, it is usually associated with but not limited to high eye pressure. If left untreated, it can lead to permanent loss of vision or blindness.
Before any laser vision correction (such as PRK, LASIK, ReLEx SMILE), a thorough pre-laser evaluation will usually be done to ascertain your suitability for surgery, and at the same time, to pick up or rule out any existing eye conditions. Some of these eye conditions will have to be treated or managed before any form of lasers are to be carried out. This is to optimise your surgical outcome post-surgery.
It is best to discuss and weigh the risks vs benefits of the surgery with your eye surgeon before proceeding.
