									6. How is LASIK likely to affect my need to use glasses or contact lenses as
I get older?

LASIK treatment can effectively correct your refraction error, no matter how
old you are. However, the fine focusing lenses inside your eyes firm with
maturity and no longer provide the capability of clear reading vision over the
age of 40. This means that even if you have surgery, you will still need reading
glasses to see clearly up close above approximately 40 years of age. The age
when you are in need to use reading glasses varies individually. Laser surgery
may be able to give you a clear vision for all the other focal distances, without
regular glasses, for the rest of your life. You may also wish to consider
monovision. This is an option for patients over 40 years old undergoing LASIK.

It achieves functional vision at both – distance and near by full correcting the
dominant eye and undercorrecting the non-dominant eye. Please ask your
doctors for details at the time of your assessment.

Inform your doctor on any current medications or if you have any allergies, as
these may cause problems with healing. Also discuss whether you should eat
or drink before surgery. It is understandable to have concerns and anxiety on
the procedure but it is also important to discuss any questions or issues
pertaining to LASIK with your doctor.
