Advanced Eye Care and Surgery- LASIK Round Rock

Chances are, you know someone who has had Laser Vision Correction. Since the excimer laser’s approval by the FDA in 1995, millions of people have eliminated their nearsightedness, farsightedness and astigmatism and said good-bye to their dependence on glasses and contact lenses.

Until recently, Laser Vision Correction treated patients strictly based on their optical prescription. Using standard laser correction, two individuals with the exact same glasses prescription would be treated with exactly the same laser treatment plan, despite the fact that, like a fingerprint, their eyes each have a unique set of naturally occurring optical imperfections and distortions. We call this conventional Laser Vision Correction.

Today, with the advent of wavefront diagnostic technology, wavefront guided excimer lasers can now treat patients according to the uniqueness of their entire optical system, not just their prescription.

Wavefront technology was pioneered for astronomy and physics to aid in reducing aberrations or imperfections in the optical systems of telescopes. In much the same way, wavefront-sensing devices are being used to produce an accurate picture of the optical imperfections found in the human eye. This technology differs from traditional testing methods in its ability to measure the entire optical system of the eye, instead of simply the front surface of the eye.

Light travels in a procession of flat sheets known as wavefronts. These wavefronts enter the eye, pass through the entire optical system (the cornea, lens and retina) and are then relected back. When the optical system has perfect refracting surfaces, these wavefronts exit the eye as flat sheets. But when the cornea is irregular of the lens is imperfect, higher-order aberrations are created, and the wavefronts exit the eye as irregular, curved sheets.
