Who is a good candidate for LASIK?

Hi, it’s Matt Russell from VSON Laser Vision Specialists. Are you suitable for LASIK? 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 – 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 – 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 – Your eye surgeon may advise you against the LASIK procedure if your prescription is very high – due to short-sightedness, long-sightedness or astigmatism.
• If you have a severe refractive error, another surgery may be better suited – 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 – 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’s parent(s) or guardian.
• If you’re over 40, age-related conditions may still occur – 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.
• You should have stable vision – Teenagers and many young adults often experience changes in their contact lens prescription and eyeglass prescription from year to year. Therefore, it’s 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 – 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 – 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 – 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.
