What eye conditions does lasik eye surgery correct?

Answer 1

LASIK can correct a wide range of vision problems related to the need for glasses or contact lenses. Ametropia, the condition of having an eye which is out of focus can be caused by a mismatch between the cornea and the optics of the rest of the eye resulting in light not being focused properly on the back of the eye to produce a clear image.

The most frequently corrected vision problem is myopia or nearsightedness. Also correctable is farsightedness or hyperopia. Also there is a condition of assymetry of the cornea which is called astigmatism, and this can also be corrected by LASIK.

Of interest is that many patients have a combination of two of these conditions together and this can also be corrected by LASIK. Most commonly nearsightedness with astigmatism. Also there is farsightedness with astigmatism. More uncommon is what is called "mixed astigmatism" where the eye is both near and farsighted at the same time in different meridians or directions. All of these conditions can be effectively treated with LASIK.

More recently there is even the correction of irregular shapes in the cornea which are correctable by a variety of new methods of custom treatments. There is wavefront treatments based on the overall shape of the eye and topography guided treatments based on the shape of the cornea in a particular patient. Most patients do not need or derive additional benefit from these types of treatments, although wavefront "optimized" custom treatments have been found to provide better quality of vision and are widely used by advanced lasers available today.

Other eye problems and diseases are not treatable with LASIK. Included is amblyopia or a lazy eye and presbyopia or the aging eye. In addition blurry vision due to diseases such as cataracts or glaucoma are treatable but not by LASIK procedures.

For most people, if their vision is correctable with glasses or contact lenses, it will also be correctable in a more permanent way by LASIK vision correction.

Answer 2

Laser eye surgery is used to correct refractive errors. LASIK, one type of laser refractive eye surgery or PRK which came first, reshape the cornea in order to produce clear vision. The procedure can treat myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. There are also laser-type eye surgeries that can treat other problems like thin corneas. Conductive Keratoplasty is another option, but it uses radio-frequency energy for corneal shaping.

Answer 3

Lasik eye surgery will correct most sight problems. If you have glacoma or an astigmatism the lasik eye surgery cannot be performed. If, however, you have near or far sightedness, this surgery will correct you vision to 20/20.

Answer 4

Lasik eye surgery is intended to correct people's vision. It is a surgical procedure that consists of shooting a laser into the eye to correct nearsightedness or farsightedness; many people choose this option so they do not have to buy contact lenses or prescription glasses. Lasik reshapes the cornea.

Answer 5

myopia (nearsightedness), hyperopia (farsightedness), or astigmatism

Answer 6

The most common eyesight problems that can be corrected with Lasik surgery are Nearsightedness (myopia),Farsightedness (hyperopia),Astigmatism,Presbyopia.
