Candidacy for LASIK Eye Corrective Surgery

Although LASIK laser vision correction is suitable for the vast majority of patients, it doesn’t necessarily mean that everyone should automatically assume that they can have the treatment. For a small number of patients, there may be some reasons why it is not the best treatment for your individual needs and in these circumstances, your consultant will recommend a more suitable alternative.

Here are some of the key criteria that you will need to meet in order to be deemed a suitable candidate for LASIK eye correction surgery at our optometric practice in Omaha, NE.


Your prescription falls within the correct ranges

In order to be considered a suitable candidate for LASIK, the level of correction needed can’t be too extreme. The U.S. Food and Drug Administration (FDA) has approved LASIK for use in patients with the following prescriptions:

Nearsightedness (Myopia) – Up to -12 diopters

Farsightedness (Hyperopia) – Up to +6 diopters

Astigmatism – Up to 6 diopters

If your prescription strength is significantly stronger than the limits specified above, it may be that LASIK will not provide a sufficient improvement for your level of vision loss. While you may have some degree of improvement, it is likely that you will still require the use of visual aids such as glasses or contact lenses.

Your prescription is stable

Visual acuity can change with age and other factors. However, whilst it is still changing there is very little point undergoing LASIK as your vision could worsen again a short while later. For this reason, we recommend that any candidate has had a stable prescription for a minimum of two years before they consider LASIK. If your prescription isn’t stable or has changed frequently in the past, you may be found to be unsuitable for the process.

Your cornea is healthy and a suitable thickness

The LASIK process involves the reshaping of the corneal tissue so that light is refracted correctly and that you can see clearly without the need for prescription eyewear. However, in order for this process to be successful, your corneal tissue must first be healthy and suitable thickness. If it is too thin, your risk of complications is greatly increased, and this could mean that you are unsuitable for LASIK. Equally, if your cornea is too misshapen then you may not get the best results and outcome from a LASIK procedure.

Good eye health

Finally, your consultant will need to check the general condition and health of your eyes to make sure that you aren’t suffering from any eye diseases that require treatment before you can undergo LASIK. For this reason, you will be asked for comprehensive information about your eye health and general medical history to ensure that you do not have any health issues or are taking any medications that could increase your risk of complications or compromise your result.
