Risk factors for retinal detachment after cataract surgery. A population-based case-control study.

摘要: Purpose: Previous analyses of Medicare claims data, as well clinical series, have suggested that performance neodymium:YAG (Nd:YAG) laser posterior capsulotomy after extracapsular cataract surgery increases significantly the risk retinal detachment. However, methodologic problems with previous research limit strength conclusions can be drawn from these earlier studies. This study was designed to resolve those methodological limitations while using a population-based approach for assessment independent association between Nd:YAG and pseudophakic Methods: A nested case-control conducted. beneficiaries who had undergone extraction 1988 1990 were identified 5% sample data. Within this cohort, people diagnosed or treated detachment during years through 1991 (cases) records. Four controls matched each case an incidence density design. Providers patients' contacted asked provide data all cases they treated. Results: Seven hundred six originally After exclusions due ineligibility, total 291 870 available analysis. Conditional logistic regression models showed number factors associated independently excess surgery. These included (odds ratio [OR] = 3.8; 95% confidence interval [CI], 2.4–5.9), history (OR 2.7; CI, 1.2–6.1), lattice degeneration 6.6; 1.6-27.1), axial length 1.211mm; 1.03-1.43), refractive error 0.921diopter; 0.88–0.95), ocular trauma 6.1; 4.3–28.2). Conclusion: Performance is elevated in patients extraction. Other include length, myopia, capsular rupture surgery, degeneration,
