Your eye will feel a bit gritty, like LASIK, but your vision will be good straight away although it may take a bit of time to become excellent. It uses the laser to cut a disc within the cornea that your surgeon removes through a small incision on the surface. ![]() The third option is SMILE (small incision lenticule extraction).Although your eye can feel a bit gritty, you will have excellent vision within a day or two. Afterwards, the flap is repositioned carefully. The first creates a flap in the cornea, while the second puts your prescription on the cornea under the flap. LASIK (laser assisted in situ keratomileusis) uses two lasers.Your eye can be sore immediately afterwards, but your vision is quite good straight away and will become perfect after a few weeks. The skin of the eye - the epithelium - is disrupted and takes a few days to heal. Surface treatment (photorefractive keratectomy or PRK) puts your prescription directly on the front surface of your eye.There are three types of laser eye surgery. There are a few alternatives to tackle this problem, but there is no perfect solution. Things become a lot more complex at the point your lens stops working. Then it continues to change - albeit much more slowly - until you are about 20.įrom then there's very little change until your mid-40s, when the lens in your eye becomes stiff and stops doing the fine focusing it used to - a condition known as presbyopia. The shape and size of your eye changes rapidly up until you are about 18 months old. But it is most effective at times in your life when your eyesight is stable. Laser surgery simply moves the prescription from your glasses onto your cornea so that light focuses sharply on the retina. It's more like a rugby ball and light focuses at different points on the retina. There's a third vision problem as well called astigmatism, where your cornea is not perfectly round. ( Supplied: National Eye Institute/National Institutes of Health) The two most common vision problems are myopia and hyperopia. ![]() If the light focuses behind the retina - known as " long-sightedness" or hyperopia - you'll find it harder to focus on things close up. Myopia is caused when the focusing power is too strong and the light focuses in front of the retina, making it hard to see things in the distance. Sometimes the alignment between your cornea, lens and retina is not in perfect synch. The lens, which sits behind the coloured part of your eye, does the final 20 to 30 per cent. The cornea, at the very front of the eye, does most of the work. Your ability to focus comes down to two structures: the cornea and the lens. Just like you have to focus light to take a good photo, you have to focus light onto the back of the eye, the retina, to see clearly. Glasses and contact lenses give your eyes the extra power they need, as long as you have regular check-ups to make sure the prescription is right.īut some people find glasses cumbersome and restrictive, or just plain annoying, so they opt to have laser eye surgery.īefore you choose to walk - or stumble - down that path, there's a few things you need to know about your eyes and the procedure.
