Eye doctors have come up with a new computer technology that analyzes the cornea’s shape during LASIK procedure and adjusts automatically the laser according to the unique problems of the cornea. This new software enables LASIK to correct new types of vision problems other than the usual astigmatism, nearsightedness and farsightedness.
Ophthalmologists from the University of Rochester in New York say their nomogram is a system that targets the subtler vision imperfections and corrects them. They disclosed that 20 percent of patients who had underwent LASIK still suffered slight eye problems after surgery but with the new software, the number is expected to drop to two percent. The nomogram’s major benefit is that it reduces the likelihood of a patient to have retreatment after the LASIK procedure.
A test is initially done to patients to find irregularities in their eyes. The information obtained is then inputted into the nomogram using computers and helps in controlling and adjusting the laser beam during LASIK surgery to correct flaws for a 20-20 vision. The system ensures that patients see clearly right after surgery.
