【Abstract】 Objective To evaluate the clinical effects of novo laser in situ keratomileusis on refraction return or insufficient correct. Methods 38 cases (70 eyes) had accepted novo laser in situ keratomileusis for their refraction return or insufficient correct, and had been followed up for 12 months. Results All the cases had no operative or postoperative complication occurred. After 12 months follow up, the naked vision of 68 eyes (97.14%) got equal to or better than preoperative corrected vision. The rest diopter was less than +1D in 69 eyes (98.57%) Conclusion When the corneal stroma thickness is > 250 μm, novo laser in situ keratomileusis is a safe and effective method for refraction return or insufficient correct.更多还原
