You might consider eyesight problems as an indication of getting older, but short-sightedness disproportionately affects younger people in the prime of their life. Along with the rate of people diagnosed with myopia is on the upswing. It is projected that by 2050, half of the people globally will need glasses to fix short-sightedness.

Eye and your suitability for laser surgery — changes as you age. If you wear eyeglasses, you’re not alone. Approximately half of all Singapore wear prescription glasses or contact lenses. cataract surgery

Most Singapore who use glasses or contact lenses — around 30 percent — need them to see in the distance, a condition called short-sightedness or myopia. Another 20 percent need them for seeing up close.

But some people today find glasses cumbersome and restrictive, or just plain annoying, so they opt to get laser eye surgery. Before you choose to walk or stumble — down that path, there is a couple of things that you want to know about your eyes along with the procedure.

The way your eye works Just like you have to focus light to bring a fantastic photograph, you need to focus light onto the rear of the eye, the retina, to see clearly. Your ability to concentrate comes down to two structures: the cornea and the lens. The cornea, at the very close of the eye, does the majority of the job.Cataracts

The lens, which sits beneath the colored part of your eye, will the last 20 to 30 percent. On occasion the alignment between your cornea, lens and retina aren’t in excellent synch. Myopia is due if the focusing power is too strong and the light focuses in front of the retina, which makes it difficult to find things in the distance. When the light focuses behind the retina — called”long-sightedness” or hyperopia — you will find it more difficult to concentrate on things close up.

The two most common eyesight problems are myopia and hyperopia.

It is similar to a rugby ball and light focuses at different points on the retina. Nonetheless, it is best occasionally in your life as soon as your vision remains stable.

The shape and dimensions of your eye change quickly up till you’re about 18 months old. Then it continues to change — albeit much more slowly — until you’re about 20. From then there’s very little change before your mid-40s, once the lens in your eye gets rigid and stops doing the nice focusing it used to — a condition called presbyopia. Things become a whole lot more complex at the point your lens stops functioning. There are a couple of choices to tackle this problem, but there’s no ideal solution. Which are the kinds of laser eye surgery?

There are three types of laser eye surgery. •            palliative therapy (photorefractive keratectomy or PRK) sets your prescription directly on the front surface of your eye.

The skin of the eye — the epithelium — is interrupted and takes a few days to heal. Your attention can be sore immediately afterward, but your vision is quite good right off and will become ideal after a couple of weeks.       LASIK (laser-assisted in situ keratomileuses) uses two capsules. Afterward, the flap is repositioned carefully. Although your eye may feel somewhat gritty, you will have excellent vision within a day or two.           The third option is SMILE (small incision lenticule extraction). It utilizes the laser to cut a disk within the cornea your surgeon removes through a small incision on the surface.

Your eye will feel a bit gritty, like LASIK, however, your vision will be good straight away even though it might take a bit of time to become excellent. Laser surgery is not covered by Medicare, and the costs vary depending on the type of procedure. Which will be the best procedure for me? Evidence from premium quality reviews shows that all three techniques give equally good eyesight by a single year.

But every type has its own limitations, risks, and side effects — it is a surgical procedure after all — so you want to talk with your physician to figure out which procedure is best for you.
