With Lasik eye surgery gaining its popularity around the world, the development of Singapore’s LASIK surgery popularity has also received a boost and now one of the most popular eye surgery in Singapore.
Although the LASIK surgery is known for its effectiveness and safety, because of its surgical nature, there are still risks associated with the surgery. Such as loss of vision or lines of vision that cannot be corrected, glare, halos, and/or double vision that can seriously affect nighttime vision, problem seeing clearly at night or in fog, severe dry eye syndrome.
Another frequently asked question is that if the results from LASIK surgery are permanent; the short answer is yes. The first Lasik procedure was done in 1989. To date, several millions of cases have been done worldwide, mostly with good results. Research studies have shown the results to be stable as long as established treatment protocols are followed. It is also the general consensus of eye surgeons and researchers worldwide that these results are likely to remain stable in the future.

However, there are exceptions.
Unstable results have occurred when the amount of cornea tissue sculpted exceeded recommended treatment guidelines. Occasionally, unstable results have occurred because of treatment of eyes with undiagnosed keratoconus. Keratoconus is a condition characterised by cone-shaped thinning of the cornea. Its presentation is often subtle in the early stages and can only be diagnosed with specialised instruments.
Before you undergo a LASIK surgery, you should also keep in mind that for in patients with very large refractive errors, results are generally not as good. Be sure to manage your expectations and have a thorough discussion with your doctor. In some cases, you may still need glasses or contacts after a successful surgery.
Additionally, results may diminish with age for some farsighted patients. This may occur if your manifest refraction (a vision exam with lenses before dilating drops) is very different from your cycloplegic refraction (a vision exam with lenses after dilating drops).
