When it comes to laser vision correction procedures such as LASIK or PRK, individuals with glaucoma must take special precautions. Generally, those being treated for glaucoma are not suitable candidates for LASIK surgery due to the suction device used in the eye during the creation of the corneal flap. However, those with mild glaucoma may be eligible. Laser eye surgery is best suited for those with a moderate degree of refractive error and no unusual vision issues.
Cataracts, which blur or distort vision and are usually found in people over 65 years of age, are a lens-related disease and, as such, LASIK won't correct them. If you have cataracts, you should be supervised by a cataract specialist to determine when cataract surgery would be appropriate. If vision correction is still necessary after cataract surgery, LASIK surgery may be an option. Certain conditions may be contraindications to LASIK surgery.
These include autoimmune diseases or diabetes, dry eye syndrome (which involves insufficient or abnormal tear production), various eye injuries, and a range of conditions that attack the optic nerve, collectively known as glaucoma. Not everyone is a good candidate for LASIK eye surgery. Amblyopia can still be corrected with LASIK; however, it will only allow you to achieve your better-corrected vision with continued use of eyeglasses or contact lenses. During the procedure, a flap is created with a microkeratome or a femtosecond laser and then the stroma is removed to create the refractive correction.
The appearance of the optic nerve in these patients can be difficult to interpret due to its abnormal appearance similar to that of an eye with glaucoma. From a refractive surgeon's perspective, the possibility that many nearsighted people will develop glaucoma later in life may not seem like a big deal since people who undergo refractive surgery are usually young and healthy. However, even with standard LASIK, the risk of eyeglobe rupture is still very low so there's probably no significant advantage with PRK. When considering laser vision correction procedures such as LASIK or PRK for people with glaucoma, it is essential to consult with an experienced ophthalmologist who can evaluate your individual case and determine if you are a suitable candidate for the procedure.
