How alcohol affects your eyes
We talk about LASIK* in this article, as it’s the most performed laser refractive surgery, accounting for approximately 95% of all procedures.
LASIK is a standard surgical procedure used to correct vision problems - specifically, those caused by refractive errors. In eyes with normal vision, the cornea bends (refracts) light precisely onto the retina at the back of the eye. A refractive error is where your cornea fails to bend light correctly, distorting your vision. It can cause blurry vision (astigmatism), nearsightedness (myopia) or farsightedness (hyperopia).
LASIK* is an acronym for “laser-assisted in situ keratomileusis.” In situ means “in place” and “keratomileusis” is the medical term for reshaping your eye’s cornea.
Results vary from centre to centre, but around 90% of people who undergo laser eye surgery have vision between 20/20 and 20/40 (without glasses or contact lenses).
20/20 vision is normal, healthy vision — not “perfect” vision. With 20/40, you can see at 20 feet what an average person sees at 40 feet.
Studies have shown that an average of 95% of individuals who have had laser eye surgery are satisfied with the results.
You will be awake during the surgery, which typically takes less than 30 minutes. (Note: you should not drive yourself home after the surgery.)
A laser makes a small cut, or flap, in the cornea. This flap is lifted, and the laser removes a tiny amount of tissue from the cornea. The flap is then placed back into its original position, where it will heal on its own.
The cost of LASIK surgery can vary depending on several factors (location of the surgery, the experience /qualifications of the surgeon, technology used, etc.).
On average, LASIK surgery can cost anywhere from £800 (US$1,000) to £3,200 (US$4,000) per eye. But it can be higher or lower depending on the above factors.
LASIK is not typically covered by the NHS or medical insurance plans, so patients may have to cover the cost. However, some surgeons or clinics offer financing options.
Recovery time from laser eye surgery is quick. You might be able to return to most of your normal activities as early as the day after the procedure (including driving).
Other activities may take a bit longer:
Your ophthalmologist or surgeon will consider the above factors and others before deciding if you’re a good candidate for LASIK.
