Based on our clinical data and audit as well that of regulatory authorities like the FDA, Lasik/IntraLASIK surgery is highly accurate. We take treatments very seriously and go through considerable care to ensure accuracy of correction. 98% of patients undergoing correction for shortsight obtain 20/20 (6/6) vision and 85% 20/25 (6/5). In spite of advanced technology and attention to detail, a small number of patients do require a touch-up or enhancement to achieve good unaided vision. This is because everyone responds differently and there is some variation in how people respond and heal. We are very proud to have a very low enhancement rate at less than 1%.
