LASIK laser eye surgery improves vision and the improved vision outcomes are permanent in most of the cases, as it has very high success rate. That is why LASIK surgery is preferred by most of the patients, who suffer from refractive error problems, like nearsightedness, farsightedness and astigmatism.
Life of LASIK
To determine the lifetime of the benefits of LASIK, visual acuity is measured by the researchers, right after the surgery procedure. In some cases, additional acuity measurements are also considered as the time passes. The values measured right after the surgery are retained and compared with the visual acuity values taken after years of the procedure. If these values do not match, the benefits and results of the surgery are considered to be fading out.
When LASIK surgery was totally unfamiliar to the people, many studies were taken place, like the above, in all over the country. After numerous researches and studies and the respective reports, LASIK is started considering as a standard laser eye surgery to correct refractive error permanently. The modern studies show how well the outcomes are achieved.
Research Studies and Reports
The Middle East African Journal of Ophthalmology had researched the life of LASIK results and it followed the LASIK patients for 10 years. The studies have reported that 98.5% of the LASIK patients have continued to be satisfied with surgery results after 10 years. This research had not measured visual acuity of these patients, but distributed questionnaire and collected the patients’ opinions in the aspects of LASIK results and quality of life.
Probable Vision Problems Long After LASIK
LASIK can resolve the problems associated with the refractive errors, however, vision problems can be stemmed from many other sources also, which cannot be controlled by LASIK laser surgery. So, the following can be the other sources of vision problems for human eye.
- Changes With Age
Presbyopia is possible at the older age, especially after 40 years. The cause of this problem is hardening of the eye’s lens, which are controlled through weakened muscles. Eventually, the closer objects may seem indistinct and blurry. That is the reason, why many older people can read only through the reading glasses.
- Change of Prescription
Change of the prescription of the eye is possible in minor cases of LASIK surgery, where the outcomes are not to the expected levels. Another cause of change of the prescription can be growing eye health issue, which is not considered as the failure of LASIK.
So, after LASIK surgery, the results are permanent for more than 95% of cases and the rest of the percentile of patients still can undergo enhancement procedure to achieve the expected outcomes. Definitely, the results are long lasting and permanent almost.
