What Types Of Vision Problems Does Refractive Surgery Correct?

Refractive Surgery Fixes

Refractive surgeons perform a number of refractive surgery procedures – such as LASIK, PRK, lens implants, and cataract surgery. Each is focused on improving the focusing ability of your eyes, depending on whether you have myopia, hyperopia, astigmatism, presbyopia or cataracts.

Similarly, each procedure reshapes your cornea or implants a lens inside the eye to correct this variety of common vision problems.

Astigmatism

With astigmatism, the cornea is irregularly curved, causing vision to be out of focus. Astigmatism can be corrected with refractive surgery techniques that selectively reshape portions of the irregular cornea, making it smooth and symmetrical, thus improving the focus of light into the eye to provide clear, crisp vision.

Nearsighted (myopia)

If you are nearsighted (myopic) you have a steeper cornea, making it difficult to see things far away. Refractive surgery can reduce the curvature of the cornea to improve your distance vision.

Farsighted (hyperopia)

If you are farsighted (hyperopic), you have a cornea that is too flat, making it hard to see things up close. Refractive procedures increase or steepen the curvature of the cornea to sharpen your reading and near vision.

Types of Vision Problems

Presbyopia

Presbyopia is an age-related vision condition that causes blurring in the near-vision range. Typically around the age of 40, vision for reading, sewing, and other close-range activities is no longer crisp and clear.

Presbyopia is caused by a stiffening of the eye’s lens, resulting in a lack of flexibility to accommodate a range of focus. Surgeons use a variety of refractive surgical techniques, including LASIK, PRK, and lens replacement to treat presbyopia.

Cataracts

A cataract is the clouding of the eye’s lens—which blocks light to the retina—resulting in poor vision. Surgery to correct cataracts involves removing the damaged lens and replacing it with a clear artificial lens. Today’s lens technologies do more for cataract patients by correcting nearsightedness, farsightedness, and astigmatism.

If you have vision problems and are interested in your surgical options for vision correction, schedule a consultation with us.
