Standard or conventional LASIK uses the patient’s prescription alone as the guide to treating a patient’s refractive error - nearsightedness, farsightedness, or astigmatism. Custom LASIK refers to computer-optimized LASIK and uses the “wavefront” technology to measure the eye from front to back and creates a three-dimensional (3-D) image or mapping of the eye. This corneal mapping, which is like the fingerprint of each patient’s eye, allows your LASIK surgeon to not only treat the refractive error but the higher-order aberrations – the peaks and valleys of the cornea. These aberrations include poor night vision, glares and haloes, starbursts, and low-contrast vision problems. With computer-optimized technology, we can actually soften that transition to recreate the round shape of the cornea. It can decrease the chance of getting glares and halos. It’s better for patients and better for maintaining the stability of the procedure afterward. To learn more about Custom LASIK, please read the article, What is Custom LASIK by LasikPlus Dallas LASIK surgeon, Dr. Robert Smith.
