Why you don’t see clearly; conditions that affect your vision. 


LASIK Vision Correction can correct Myopia, Hyperopia, and Astigmatism.  With LASIK, the surgeon creates a flap on the surface of the cornea, opens the flap and then uses the laser to reshape the corneal tissue under the flap. The goal with LASIK is to make a permanent correction to the shape of the cornea, so that light properly focuses on the retina, and you can see clearly.

Normal Vision: With normal vision, the eye is the correct length for images to focus properly on the retina.  The shape of the eye is round, like a basketball.

Myopia: With myopia, or near-sightedness, the eye is too long.  The focal point of the images is in front of the retina, causing vision to be blurry at a distance.

Hyperopia: With hyperopia, or far-sightedness, the eye is too short. The focal point of the images is behind the retina, causing vision to be blurry close up.

Astigmatism: With an astigmatism, the cornea of the eye is irregularly shaped, like a football.  Astigmatism can be present along with any of the above visual conditions.

The Visual Condition that LASIK CANNOT CORRECT.

Presbyopia:  Presbyopia, which literally means “old eye” in Latin, is a condition of the eye that happens with normal aging. When patients reach the age of 40-50, they begin to notice that near images aren’t as clear as they used to be, and they may need reading glasses.

With presbyopia, the lens of the eye begins to lose it’s elasticity, and the muscles that control the focusing of the lens become less flexible. This normal aging condition will affect everyone as they grow older, whether they have LASIK or not. Over the counter reading glasses can be used to correct presbyopia.
