Purpose: To analyze the patient reported outcome of satisfaction after LASIK surgery., Design: Systematic review., Participants: Patient data from previously reported studies., Methods: A literature search conducted for the years 1988 to 2008 that included pertinent LASIK surgery information from the review of 2915 retrieved citations. All abstracts from these citations were reviewed and 1581 were deemed to be relevant for review. Complete copies of each of these relevant (1581) articles were obtained, and after thorough analysis each was rated based on the strength of the study design and weight of evidence. A level I rating was assigned to properly conducted, well-designed, randomized clinical trials; a level II rating to well-designed cohort and case-control studies; and a level III rating to case series, case reports, and poorly designed prospective and retrospective studies. Level I and II rated, peer-reviewed articles were entered into a database, and level III articles were eliminated. A total of 309 articles were incorporated into this database, representing level I and level II well-controlled studies of primary LASIK surgery., Main Outcome Measures: Patients' satisfaction rates and factors associated with dissatisfaction., Results: Nineteen of the 309 database articles (6.1%) reported on both patient quality of life and satisfaction and together encompassed a total of 2198 subjects. The procedures from these 19 articles took place between 1995 and 2003. The overall patient satisfaction rate after primary LASIK surgery was 95.4% (2097 of 2198 subjects; range of patient satisfaction for the 19 articles was 87.2%-100%). The patient satisfaction rate after myopic LASIK was 95.3% (1811 of 1901 patients), and after hyperopic LASIK was 96.3% (286 of 297 subjects)., Conclusions: Based on this review, worldwide, an average 95.4% of patients were satisfied with their outcome after LASIK surgery. With 16.3 million procedures performed worldwide, and more than a decade of clinical studies and technological innovation, LASIK surgery should be considered among the most successful elective procedures. LASIK surgery compares more favorably with other elective surgical procedures in terms of generally higher satisfaction rates.

Purpose: To evaluate the effects of a superior or nasal hinge location on corneal sensation and dry eye after laser in situ keratomileusis (LASIK)., Setting: Magill Research Center for Vision Correction, Storm Eye Institute, Medical University of South Carolina, Charleston, South Carolina, USA., Methods: This prospective randomized masked study included 47 patients having bilateral myopic LASIK surgery. The first eye was randomly assigned to have a nasal or superior hinge flap; the fellow eye had the alternate location. Visual acuity, contrast sensitivity, corneal sensation, basic secretion test, tear film breakup time, conjunctival and corneal staining, and a subjective questionnaire were evaluated preoperatively and postoperatively at 1 week and 1, 3, and 6 months. The Wilcoxon signed rank test and paired t test were used for comparison., Results: Dry eye occurred with the same frequency in both groups. However, eyes with the nasal hinge had significantly better nasal sensation than those with the superior hinge (P<.05) at 1 month., Conclusion: Better nasal corneal sensation was found at 1 month in the nasal hinge group but there was no difference in any other parameters measured.
