What Can LASIK Correct?

LASIK is performed to correct refractive errors – those irregularities that do not allow light entering the eyes to focus properly on the retina (the back of the eye). There are three main vision characteristics that LASIK can correct:

1.Nearsightedness (Myopia): Distant objects appear blurry because the curve of the cornea is too steep so images are focused in front of the retina. LASIK can flatten the curve of the cornea.

2. Farsightedness (Hyperopia): Close-up objects appear blurry because the curve of the cornea is too flat so images are focused behind the retina. LASIK can create a steeper corneal shape.

3. Astigmatism: The cornea is oval-shaped, rather than round, making it difficult to focus clearly at any distance. LASIK can correct the overall corneal shape.


As most people reach their 40s, a condition called presbyopia can develop, making it difficult to read objects close-up. This is not typically the late-onset of farsightedness. In fact, it is not a refractive error at all. Instead, presbyopia is caused by the natural stiffening of an eye’s lens over time. Reading glasses become necessary to see menus, smart phones and other fine print clearly.

This condition can occur whether or not a person has had LASIK. Traditional LASIK cannot correct presbyopia; however, a technique called monovision LASIK may help. In this technique, one eye is corrected for close-up vision and the other eye is left for distance vision.
