Refractive surgery can be used when you:
• Want to decrease your dependence on glasses or contact lenses
• Are free of eye disease
• Understand that you could still need glasses or contacts after the procedure to achieve your best vision
• Have an appropriate refractive error
Short for photorefractive keratectomy, this laser eye surgery is used to correct mild to moderate nearsightedness, farsightedness, and/or astigmatism. During PRK surgery, an eye surgeon uses a laser to reshape the cornea. This laser, which delivers a cool pulsing beam of ultraviolet light, is used on the surface of the cornea, not underneath a flap of the cornea, like in LASIK eye surgery. PRK may also be done with computer imaging of the cornea.
If you have myopia, hyperopia, or astigmatism, you may be required to have photorefractive keratectomy.
This is usually painless. Drops will be used for local anesthesia and injections are not needed.
PRK surgery performed in 5 minutes, approximately.
No swimming for two months, no use of makeup for 10-14 days.
As far as the causes of astigmatism, no one really knows what brings them on. There is some evidence, however, to suggest they may be hereditary, as they are usually present in an individual at the time of birth. As you grow older, the degree of the astigmatism can change over time. It just depends on genetic heritage, and how well you take care of your eyes. Most people today do have some form of an astigmatism, but for many people it is so slight it does not affect their vision, so it often goes unnoticed. If you have a more severe astigmatism however, chances are your doctor has prescribed you contact lenses or glasses.
People who are glaucoma suspects or who have glaucoma are just as likely as any other to seek laser refractive surgery. LASIK is a popular ocular procedure, pain free and it is carried out with an extremely precise computer-controlled excimer laser emission. Glaucoma patients interested in LASIK surgery may visit a glaucoma specialist or another LASIK surgeon who has had experience with performing LASIK in glaucoma patients. PRK (photorefractive keratectomy), LASEK (laser epithelial keratomileusis) are good alternatives for glaucoma patients.

An ophthalmologist usually evaluates the size and the shape of your eyes before surgery using ultrasound or IOLMaster to determine the power needed for intraocular lens.
No. The appearance of eyes will not change after cataract surgery. The others will not found you had cataract surgery by looking at your eyes. The only difference is that the intraocular lens may lead to the reflection due to the more transparency of the new lens in compare with natural lens.
No. This procedure is considered as a Day Case; so, there is no need for hospitalization.
Except for special cases, usually it is preferable to surgery both eyes during one operation.
Those with cataracts or other lens diseases.
