Hi, it\u2019s Matt Russell from VSON Laser Vision Specialists. A good LASIK candidate is someone who meets specific patient criteria. Your eyes must be healthy and free from any severe dry eye syndrome, conjunctivitis (pink eye), infection or any type of eye injury. Your cornea must have sufficient thickness \u2013 Performing laser eye surgery on a cornea that is too thin or has a highly irregular surface and misshapen could compromise results and impair your vision. If your cornea is too thin for LASIK, there are other options. Your pupils must not be too large \u2013 On the other hand, if your pupils are naturally large, you could be at increased risk of side effects such as halos, glares and starbursts in low light, especially when driving at night. Your prescription must be within certain limits \u2013 Your eye surgeon may advise you against the LASIK procedure if your prescription is very high \u2013 due to short-sightedness, long-sightedness or astigmatism. If you have a severe refractive error, another surgery may be better suited \u2013 Results of LASIK surgery for the treatment of very high refractive errors are less predictable and may not be worth the cost and potential risks. If you have a severe refractive error, another type of vision correction surgery may be a better option, such as phakic IOL implantable lenses or refractive lens exchange. You must be old enough \u2013 Certain procedures require you to be 18 years old; others, 21. Patients younger than this can be treated as an exception at the discretion of the LASIK surgeon with permission from the patient\u2019s parent(s) or guardian. If you\u2019re over 40, age-related conditions may still occur \u2013 Generally, there is no upper age limit to laser eye surgery. However, it is important to note that once you hit your 40s, you may still need reading glasses to correct near vision due to a normal, age-related condition called presbyopia. Your vision must be stable \u2013 Teenagers and many young adults often experience changes in their contact lens prescription and eyeglass prescription from year to year. Therefore, it\u2019s important for refractive errors to be stable for at least 12 months before undergoing LASIK or other refractive surgery. You must be in good health \u2013 If your body has trouble healing, you will have a higher risk of an unsatisfactory LASIK surgery outcome. If you are pregnant, you should delay surgery \u2013 The LASIK procedure is not suitable if you are pregnant or nursing. Hormonal changes can alter the shape of your cornea, leading to temporary changes in your vision. You must have realistic expectations \u2013 While the vast majority of LASIK surgery results are excellent, you should be fully aware of the possible side effects, risks and potential LASIK complications before you choose to undergo the procedure.
