To analyze outcomes of resident-performed phacoemulsifications and to assess the resident phacoemulsification learning curve.
Retrospective chart review of resident-performed phacoemulsification cases at the Atlanta Veterans Affairs Medical Center, Decatur, Georgia, from July 1, 1999, through June 30, 2002. Outcomes measured included postoperative uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BSCVA), intraoperative complications, and adjusted phacoemulsification times (total phacoemulsification time multiplied by phacoemulsification power used).
We analyzed 680 cases. Postoperative mean UCVA was 20/39, and mean BSCVA was 20/25 (> or = 20/20 in 44.0% of cases and > or = 20/40 in 97.8%). There were no differences in visual acuity outcomes over the course of residency training. Intraoperative complications occurred in 34 cases (5.0%), with a significant reduction in vitreous loss rates after the first 80 resident cases (5.1% vs 1.9%; P = .03). Mean adjusted phacoemulsification time was 0.68 minutes, with a significant reduction in adjusted phacoemulsification time after the first 80 cases (0.87 vs 0.52 minutes; P < .001).
Quality visual outcomes after phacoemulsification can be attained throughout residency training; however, surgical competency, when measured by complication rates and phacoemulsification efficiency, continues to improve significantly with increasing surgical experience well beyond the first 80 resident phacoemulsification cases.
分析住院医师进行的超声乳化白内障吸除术的结果,并评估住院医师超声乳化白内障吸除术的学习曲线。
对1999年7月1日至2002年6月30日在佐治亚州迪凯特市亚特兰大退伍军人事务医疗中心由住院医师进行的超声乳化白内障吸除术病例进行回顾性图表审查。测量的结果包括术后未矫正视力(UCVA)、最佳眼镜矫正视力(BSCVA)、术中并发症以及调整后的超声乳化时间(总超声乳化时间乘以所用超声乳化功率)。
我们分析了680例病例。术后平均UCVA为20/39,平均BSCVA为20/25(44.0%的病例≥20/20,97.8%的病例≥20/40)。在住院医师培训过程中,视力结果没有差异。34例(5.0%)发生术中并发症,在前80例住院医师病例之后,玻璃体丢失率显著降低(5.1%对1.9%;P = 0.03)。平均调整后的超声乳化时间为0.68分钟,在前80例病例之后,调整后的超声乳化时间显著降低(0.87对0.52分钟;P < 0.001)。
在整个住院医师培训期间都可以获得超声乳化白内障吸除术后良好的视力结果;然而,以并发症发生率和超声乳化效率衡量的手术能力,在超过前80例住院医师超声乳化白内障吸除术病例后,随着手术经验的增加仍会持续显著提高。
