Deanna Foster's astigmatism causes her to squint a lot. "I can't wait to see if I can wake up in the night and actually see, or go swimming and not run into the wall," said Deanna. At Baylor College of Medicine they're making a fingerprint of Deanna's eye. It's like a map of her eye problems or aberrations. The information from the fingerprint of the eye is programmed directly into a laser, correcting aberrations that most people never even realize they have. At this point it's all done automatically. The surgeon has no manual control. "There are levels of vision that are possible with the human eye that we haven't reached yet and the goal of this surgery done in this way is to enable us to get there," said Dr. Douglas Koch, a principal investigator. Deanna is in a study at Baylor College of Medicine. The personalized fingerprint of the eye makes the laser more accurate, giving you a more precise correction, including better sharpness, even better color. Theoretically, it could give people 20/10 vision by correcting all their vision aberrations simultaneously. After the fingerprint, a preview lens is made, giving the patient a chance to test the correction before surgery. Deanna's laser surgery on both eyes took less than 20 minutes. Dr. Koch can correct nearsightedness and astigmatism simulataneously. Five minutes after surgery, Deanna tested at 20/30. "Already good enough to drive without glasses. Oh awesome", said Deanna. The next day Deanna's vision was 20/20.
