Are the effects of LASIK eye surgery permanent?

28 May 2012

Conditions that usually need LASIK eye surgery are those that are genetically inherited. One may be born with nearsightedness or those with eyes that are too long, others with farsightedness which means they have eyes that are too short, while some may have astigmatism which means that they have eyes that are not properly shaped. LASIK eye surgery is a procedure wherein a flap in the affected eye is created to make way for the Laser treatment. The laser is then applied to correct the prescription by reshaping the cornea.

With this as a backgrounder, once the condition is treated with Lasik eye surgery, the condition is permanently fixed. However, this is said with the assumption that the patient remains healthy and is in the age approximately 25 and above wherein the person is no longer growing and so with the eyes.

Age is one of the factors to consider in evaluating the effects of Lasik eye surgery. Most of the patients that undergo this procedure are from 25 to 35 and averaging to 28 years of age, which is considered to be the most preferred stage to have the surgery. This is the stage wherein, the person still has the capacity for rapid cell repair that fosters healing while it is also the stage where the person has stopped reproducing new cells that fosters growth. Growth in the eyes may affect the corrective procedure being done because the treated condition is genetic in nature. Growth will most probably shrink, change the shape or even grow the part that was treated.

Another factor to consider is the health of the patient. When a patient has other conditions like onset Diabetes which certainly changes vision, the procedure may not have the desired result. Also, patients may have a corneal structure that is not as strong as it normally is and Lasik eye surgery may only weaken the structure even further, which may result in the loss of effect of the procedure and in rare cases the vision may be made worse than it was. It may be painstaking to pick out cases where the Lasik procedure may not bear effect or may not bear permanent results but the scans of the eyes should be religiously and carefully look on to, to avoid doing LASIK procedures in these particular cases.

Most of the patients that underwent Lasik eye surgery had permanent effects while a few had minor regression. Eye surgeons who are experienced would most probably overcorrect the eye to allow regression and fine tune the eye. This is done especially to those who are younger than 30 and who has still the capability to allow growth in the eye. For most patients Lasik eye surgery bears permanent effects and permanently changes the shape of the eye. Until advancing age deems it necessary to have reading glasses and conditions like cataract will take place. However, in the unusual cases where the patient experiences change of vision, a procedure to touch up and enhance the vision can always be performed to enhance the result.
