Project Description

Myopia (or nearsightedness) affects a significant percentage of the population, but this eye disorder is easily corrected with eyeglasses, contact lenses, or surgery.

People who have myopia or nearsightedness have difficulty seeing distant objects, but can see objects that are near clearly.

What causes myopia? 

People who are nearsighted have what is called a refractive error. In people with myopia, the eyeball is too long or the cornea has too much curvature, so the light entering the eye is not focused correctly. Images focus in front of the retina, the light-sensitive part of the eye, rather than directly on the retina, causing blurred vision.

Myopia runs in families and usually appears in childhood. Usually the condition plateaus, but it can worsen with age.

How is myopia treated?

Glasses, contact lenses, or refractive surgery can correct myopia.

With myopia, your prescription for glasses or contact lens is a negative number, such as -3.00. The lens allows the eye focus light on the retina, clearing up the vision.

Refractive surgery can reduce or even eliminate your dependence on glasses or contact lenses. The most common procedures for myopia are performed with a laser, including:

  • Photorefractive keratectomy

Also called PRK, a laser is used to remove a layer of corneal tissue, which flattens the cornea and allows light rays to focus closer to or even on the retina.

  • Laser-assisted in situ keratomileusis

In this procedure, commonly called LASIK, a flap through the top of the cornea is cutted with a microkeratome or laser. Then a laser removes some corneal tissue, and the flap is dropped back into place.

  • Phakic intraocular lenses.

Some patients with high myopia who have too high of level of myopia for PRK & LASIK or a very thin cornea can be treated with lenses placed inside the eye called phakic intraocular lenses(ICL…)

  • Clear lens extraction and IOL implant.

This technic allows to correct high myopias. Its indicated in adults over 40.
