Before undergoing to your Laser refractive procedure eye surgery evaluation there are some general criteria that can guide you in deciding if this is the right procedure for you. To have laser eye surgery you should be in good eye health, good overall health, and have realistic expectations of the Laser refractive procedure

Candidates Should Have Good Eye Health:

• Your eye prescription should fall within certain prescription limits.
• You should have have eye diseases like keratoconus, glaucoma, cataracts, corneal disease , dry eye and certain retinal and optic nerve diseases.
• You should have no residual or active eye conditions including optic neuritis, ocular herpes, some cases of amblyopia (lazy eye) AND strabismus (muscle imbalance).
• You should have no current or recurring infections and ocular allergies.
• You should have a normal corneal curvature, thickness and pupil size.

Candidates Should Have Overall Good Health:

• You must be at least 18 years old.
• To be a good candidate for Laser refractive procedure, you should not have any autoimmune diseases, such as Lupus, rheumatoid arthritis, or multiple sclerosis.
• If you have diabetes it must be well managed and under good control and not have diabetic retinopathy.
• You cannot be pregnant or nursing, or plan to become pregnant in the next 6 months following surgery. If nursing and considering Laser refractive procedure laser eye surgery,

you should wait at least 3 months after you’ve stopped. Hormonal fluctuations can affect vision stability.

Candidates Should Have realistic expectations and understands following points :

• Laser refractive procedure is a highly successful procedure ,intended to reduce or eliminate dependence on glasses or contact lenses. The people who are the happiest after Laser refractive procedure are usually those who start out with reliastic expectations about what the procedure can and cannot accomplish . For example , if your goal is to see much better nearly all the time without dependence on glasses or contacts, you are very likely to be very happy with your Laser refractive procedure experience. If your goal is to see even better after Laser refractive procedure than you presently see with your best glasses or contact lenses, you ,ay be expecting more than can routinely be accomplished with Laser refractive procedure.
• The vast majority of people undergoing Laser refractive procedure will see well enough after the procedure to carry out majority of their activities . Many will see 6/6 , or close to 6/6. However, Laser refractive procedure is not guaranteed to deliver 6/6 vision. Individual results can depend on a number of factors, one of the most important being how your particular eye heals after the procedure.
• Occasionally, people will find that a weak pair of glasses is still helpful after Laser refractive procedure for certain situations, such as night time driving. It is also possible to experience some starbursts or halos around lights at night after Laser refractive procedure surgery. In most cases these are temporary and not bothersome
• It is also important to realize that Laser refractive procedure does not stop age-related changes in the eye. If one continues to become more nearsighted or farsighted after Laser refractive procedure, some increased dependence on glasses may again develop over time. That's why it is best to have Laser refractive procedure when your glasses or contact lens prescription has been fairly stable over time.
• Laser refractive procedure neither reduces the risk of developing eye conditions later in life, such as cataracts, glaucoma, or macular degeneration nor interferes with the usual treatments for these disorders and Laser refractive procedure does not decrease the risk of certain retinal disorders that are slightly more common in highly nearsighted individuals. So regular complete eye examinations are still important after LASIK.
