What lasik eye surgery does?

Answer 1

Basically Lasik is the most popular laser eye surgery that can correct or sometimes even cure common refractive errors like Hyperopia (farsightedness) etc. What Lasik does is create a thin flap on the surface of the cornea w/c is then surgically folded to the side to let laser energy reshape the exposed surface of the cornea. After the procedure, the corneal flap is folded back for rapid recovery. If you want a visual on what I just said you can refer to the related link(Lasik Philippines) I placed below...

LASIK surgery is the most popular type of laser eye surgery to improve your vision. Laser vision correction is now in its second decade of helping patients reduce or eliminate their dependence on glasses and contact lenses. As testimony to its life changing benefits, thousands of ophthalmologists and optometrists around the world have become so impressed with the results of laser vision correction that over one million procedures are now performed each year. At New World iCare our patients continuously tell us they appreciate our commitment to being on the cutting edge of this exciting technology. One of the most popular ways to correct vision is with a procedure called LASIK (laser in-situ keratomileusis), which uses a laser to change the curvature of the cornea (outer window of the eye). LASIK has quickly become the procedure of choice for most patients because they recover quickly and have fewer side effects and complications than with other methods of vision correction. In fact, most LASIK patients notice a significant improvement in their vision soon after surgery. LASIK removes tissue within the cornea to treat low to high levels of nearsightedness, farsightedness and astigmatism. LASIK is an acronym for Laser-Assisted In Situ Keratomileusi, a refractive surgery procedure performed by Ophthalmologists intended for correcting the vision in order to reduce a person's dependency on corrective devices such as glasses or contact lenses. The procedure is usually a preferred alternative to PRK, or photo refractive keratectomy, as it requires less time for full recovery, and the patient experiences less pain overall. The first step in the procedure consists of mapping the corneal surface with a computer controlled scanning device to determine the exact shape. Then the appropriate amount of tissue which needs to be removed is calculated, such that upon replacing the flap there is no need (or less need) for corrective devices like spectacles and lenses. LASIK is a procedure that permanently changes the shape of the cornea, the clear covering of the front of the eye, using an excimer laser. A blade, called a microkeratome, is used to cut a flap in the cornea. A hinge is left at one end of this flap. The flap is folded back revealing the stroma, the middle section of the cornea. Pulses from a computer-controlled laser vaporize a portion of the stroma and the flap is replaced. When the cornea is properly reshaped, it will then better focus light onto the retina. This results in improved vision. Both nearsighted and farsighted people can benefit from LASIK. Sufferers of astigmatism can also benefit. Suitability for process Generally to be a good candidate for LASIK, you should a. Be above 17-18 years of age b. Have stable refraction (glass number) for 6 months.

Answer 3

This is a very big subject, but if I want to explain it into a couple of words, I can tell you that, the Cornea will be cut flap-like, and then with a shoal laser beam, the inner layers will be heated up to 115 degree (c), so with this work, the anterior-posterior axis of the eye will be shortened, so Myopic or nearsightedness refractive errors will be resolved.

Answer 4

It is laser eye procedure which is useful to correct vision problems.

Answer 5

Lasik stands for Laser Assisted in situ Keratomileusis, it is a common type of laser eye surgery which provide a permanent solution instead of glasses and contacts.
