LASIK is a popular refractive surgery with a high success rate. However, not everyone is a suitable candidate. For instance, you should be 18 years or older with no significant change in your spectacles or contact lens prescription for at least the last two years. There should be no medical history of any active eye diseases such as cataract, glaucoma, retinal detachment or keratoconus. Of course, your eye doctor (ophthalmologist) will be able to tell you if you are a suitable candidate after a comprehensive eye examination. But if you’re still in the early stage of making the decision and looking for more information on how you might or might not be a suitable candidate, here are a few more things you look at first to see if you might be a suitable candidate, in addition to the previously mentioned conditions.
Untreated dry eye syndrome can affect LASIK results, however, when it is diagnosed and adequately treated, the chance of successful results is just as high as those without dry eye syndrome. However, high degree of dry eye syndrome could disqualify you as a candidate for the LASIK surgery. It is necessary for anyone interested in taking the LASIK surgery to be screened for dry eye before the surgery.
Large pupil size is thought to be a factor in side effects like “glare” and “halos”. All the reasons why a careful and detailed consultation and evaluation with your doctor is needed before you make any decision.
High degree of refractive error, such as nearsightedness, farsightedness, astigmatism, might not work well with LASIK.
During your pregnancy, your refractive error might fluctuate, therefore it’s best to wait till after the pregnancy.
The thickness of your cornea should be checked before the LASIK surgery. Thin corneas might disqualify you as a LASIK surgery candidate, but there are still other possible refractive surgeries as alternatives.
You should at least be 18 years old, in some countries, it is even recommended to wait till the age of 21. This is because the younger you are, the more likely that your refractive errors are still changing.
If you’re uncertain about any of the condition mentioned above, it is recommended you consult with your eye doctor. He or she should be able to counsel you on the procedure and you should in turn take this opportunity to address any concerns that you may have about the procedure. Once you have decided to take the next step, your eye doctor should be able to confirm the stability of your refractive errors as well as conduct necessary exams to ensure you are a suitable candidate for LASIK.
