Understanding Your Problem
To better understand how refractive surgery may help correct your vision reducing and/or eliminating your need for glasses or contact lenses, lets take a look at how the eye works.
Dr. Moretsky educates a patient considering LASIK.
In order to see properly light rays must pass through different focusing agents. The light rays first pass through the cornea or clear window on the surface of the eye. The rays of light are then directed through the crystalline lens located inside the eye, which acts as another focusing agent directing the light rays to the retina on the back surface of the eye enabling it to process the image. Vision problems are generally broken up into four categories:
Myopia or Nearsightedness:
A condition when the distance between the cornea and the retina is too long or the actual shape of the eye is too steep. This causes light images to focus in front of the retina, causing blurry vision in the distance.

Hyperopia or Farsightedness:
A condition in which the distance between the cornea and the retina is too short or the actual shape of the eye is too flat. This causes light images to focus behind the retina, causing blurred vision.

Astigmatism:
A condition in which the cornea is curved more in one direction than the other causing the cornea to resemble an egg or football shape rather than being round like a basketball. Astigmatism causes blurred vision at all distances.

Presbyopia:
A normal aging condition in the eye where the lens located inside the eye loses its ability to accommodate or change focus from the distance to close up. Presbyopia typically begins between the ages of 40 and 50 years old and is the reason people need reading glasses for small or fine print.
Performing a "blended vision" LASIK correction may aid you in seeing distance and intermediate, to see smaller print there will be a need for reading glasses. Monovision on the other hand corrects one eye for distance and one eye for near vision. A prior trial with contacts is advised first before proceeding with laser vision correction for this type of surgical correction.
The correction of Presbyopia is now possible through multifocal Intraocular Lenses (IOL's). These state-of-the-art lenses allow the patient to see both near and far, with both eyes significantly reducing or eliminating the need for bifocals and reading glasses.
Moretsky Cassidy LASIK Vision Correction is proud to be the first doctors in Arizona to offer the presbyopic correcting ReSTOR Intraocular Lens. This procedure can enable a cataract patient, after surgical removal of the existing cataract, to focus on distant objects as well as objects up-close without the need for reading glasses or bifocals.
