CustomCornea LASIK is a new type of refractive surgery offered at CVCC. During this procedure we use sophisticated diagnostic data from a specialized instrument called a wavefront analyzer (known as LADARWave) to perform customized LASIK treatments. Essentially, this is a new technique for mapping the refractive errors in the eye. In the past, we’ve used a topographical map to see just the surface of the cornea. With LADARWave, Alcon’s measurement device, CVCC surgeons are now able to generate a three-dimensional map of the entire visual pathway of the eye, allowing us to see errors called “higher order aberrations.” The LADARWave device sends light rays into the eye. These light rays pass through the cornea and lens to the retina. From there, the light rays are bounced back through the eye. As they exit the eye, the LADARwave captures and measures their precise location. This data is then used to create a three-dimensional map of the eye’s visual pathway. This map is like a fingerprint, because each person’s is unique. The wavefront map is saved, analyzed by our physicians and used to guide the surgeon and the LADARVision excimer laser during the CustomCornea LASIK procedure.
Conventional LASIK is very successful at treating refractive errors on the corneal surface such as nearsightedness, farsightedness and astigmatism. However, some individuals have more complex refractive errors within their eyes called “higher order aberrations.” These aberrations can cause visual distortions such as halos, glare or blurring, particularly at night. Higher order aberrations only occur in a visually significant manner (that is, to the extent that they noticeably affect vision) in 10% to 15% of the general population. In the past, some conventional LASIK patients with higher order aberrations have noticed visual side effects in their night vision. CustomCornea LASIK is designed to eliminate this problem. If your doctor has detected higher order aberrations within your eyes, he or she may recommend CustomCornea LASIK as the best option for you.
CustomCornea LASIK
- Goes beyond reshaping your cornea based on your eyeglass prescription. It is customized to your eyes
- Can detect and treat visual errors that could not previously be detected or treated
- May give you a better chance of achieving 20/20 vision or better after LASIK.
- May give you a reduced chance of losing visual quality or contrast sensitivity.
- May give you a reduced chance of night vision disturbances and glare.
