There are so many myths built around the Lasik eye surgery, firstly because it is a new technology and secondly it is related with the eye, which is the most sensitive organ of the body. There is nothing wrong having the concern as it helps to clear the concern to start trusting the medical technology.
So, Does Lasik Wear Off?
Coming to the facts, the Lasik effects are mostly permanent and in majority of the cases, it indefinitely lasts, in unfavourable circumstances. During the Lasik eye surgery for astigmatism, farsightedness or nearsightedness, the shape of the cornea is changed with the help of the excimer laser. Cornea is an outer eye structure. The changes made over the eye are physical and technically, the changes are permanent.
What About Exceptions?
Exceptions are always there like, with any surgical procedure. A minor percentage of the patients, approximately, about less than 3% of them have their natural healing system a bit lower compared to the rest of the patients. And the exception here does not mean failure, but not 100%. In such cases, there would be still scope of getting accurate and better results. They have the solution of going through the Lasik enhancement treatment. The need for the enhancement surgery is not determined immediately after the surgery, as the healing process that takes considerable time, for a few months determine the overall success rate of the Lasik surgery, for that person. So, the need for it can be determined within 12 months of duration after the surgery.
Any Come Backs?
When the Lasik surgery is technically successfully, ideally, there should be no come back of vision or refractive errors. However, based on unique body conditions and lifestyles of the patients, it is possible that a small percentage of the patients have the probability of developing nearsightedness or myopia, in a small degree. Usually, this condition is possible for the students, who make intense study during small durations, in their 20s. The change is natural, because of the eyeball lengthening, but not because of the technical failure or problem associated with the Lasik surgery. Lasik makes the changes of cornea permanent and any other factors can contribute the need for enhancement procedure. So, natural wear off does not mean Lasik wear off.
Any Other Factors
There are other factors that determine the overall vision of the eye and the first factor to consider is the age of a person. As the age progresses, the condition of Presbyopia is quite common for the people, who go through lesser accuracy of vision. This condition has the syndrome called dysfunctional lens syndrome. The change usually starts at 40s of the people. The condition gets severe as the human reaches to 50s and 60s. The condition of Presbyopia is possible for any human being in the world, irrespective of undergoing or not undergoing the Lasik eye surgery.
Hence, ideally, Lasik does not wear off if the positive effects are retained well, with healthy lifestyle, in terms of preserving the eye vision with necessary related nutrition.
