Refraction refers to the bending of light as it passes through the cornea and the lens to the retina. Three factors can play a part in determining how well the eye refracts (or bends) light: the shape of the cornea, the power of the lens, and the length of the eyeball.
When these three factors are in correct proportion to one another, light is properly focused on the retina resulting in clear, normal vision. However, if any of these factors are not in correct proportion, refractive problems such as myopia (nearsightedness), hyperopia (farsightedness), and astigmatism can occur.
The conventional treatment for these conditions is glasses or contact lenses. However, more and more people are now choosing refractive surgery, or LASIK (laser in-situ keratomileusis), to correct their vision. A highly successful procedure, LASIK can significantly reduce or eliminate the need for corrective lenses.
Examination
The Rhode Island Eye Institute offers free screening to determine if you are a candidate for LASIK. The ideal candidate is over 18 years of age and has healthy corneas. Candidates must not have had a significant increase in their prescriptions in the last 12 months. People with certain medical conditions or women who are pregnant may not be good candidates for LASIK.
Treatment
The LASIK procedure uses the Excimer laser to surgically reshape the cornea, the clear dome in the front of the eye. First the eye is completely numbed with anesthetic eye drops and an eyelid holder is placed between the eyelids to prevent blinking. The doctor uses an instrument called a microkeratome to create a protective flap in the front of the cornea. The flap is then retracted and a small amount of corneal tissue is removed with the laser.
Some patients may be candidates for a new kind of LASIK called CustomVue™ or “wavefront”. This enhanced version uses WaveScan®-based digital technology to create a precise, customized 3-D map of the eye called a WavePrint®.
The WaveScan consists of a sensor and a laser, which sends a wave of light through the eye to the retina. As the light is reflected back through the eye, the sensor measures the unique characteristics of the eye. This information is then translated into a mathematical formula that the doctor uses to program the laser and perform the procedure.
