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 identify factors associated with intraoperative floppy iris syndrome (IFIS) in patients undergoing routine phacoemulsification., Design: Comparative case series., Participants: Analysis of 899 eyes of 660 patients undergoing routine cataract surgery., Methods: All routine cases of cataract extraction with posterior chamber intraocular lens implantation between September 1, 2005, and August 31, 2006, were documented. Pertinent patient information, including age, gender, race, medical history, and current medication use (including tamsulosin [Flomax, Boehringer-Ingelheim, Ingelheim, Germany], other alpha(1)-antagonists, angiotensin antagonists, anticholinergics, cholinergic agonists, muscle relaxants, nitric oxide donors, and saw palmetto), were collected at the time of surgery. A telephone survey was used to determine previous use of tamsulosin, other alpha(1)-antagonists, and saw palmetto. Cases were identified intraoperatively as IFIS or non-IFIS following the triad of criteria developed by Chang and Campbell., Main Outcome Measures: Presence of IFIS associated with medication use and medical history., Results: Analysis showed IFIS in 27 patients (4.1%) representing 33 eyes (3.7%). Tamsulosin use (P<0.001) and history of alpha(1)-antagonist use other than tamsulosin (P = 0.01) were shown to strongly correlate with IFIS in our study. Hypertension was noted to be a significant variable via multivariable generalized estimating equations analysis (P = 0.04) with a prevalence of 75.8% in patients with IFIS versus 56.4% in patients without IFIS. Saw palmetto showed a slight, but statistically insignificant, trend that current use or history of use may be associated with IFIS. There were no cases of posterior capsular rupture or vitreous loss., Conclusions: Exposure to tamsulosin highly correlates with IFIS. Use of other alpha(1)-antagonists is also associated with IFIS. Several patients in our series were identified to have IFIS with no history of alpha(1)-antagonist use, indicating that other etiologic factors, or a combination of factors, can also elicit this response. Multivariable regression analysis shows no proven relationship between IFIS and individual use of angiotensin antagonists, anticholinergics, cholinergic agonists, muscle relaxants, nitric oxide donors, or saw palmetto, and diabetes or congestive heart failure.
