Conversion from extracapsular cataract surgery to small-incision phacoemulsification is inevitably associated with a learning curve. Retrospective analysis of one surgeon's learning curve was carried out on the first 50 consecutive operations using small-incision phacoemulsification. Parameters were evaluated, including postoperative acuity and astigmatism at eight days, three weeks, three months, and six months. A comparison of the results of the first 25 operations and the subsequent 25 showed statistically significant differences only in acuity at eight days and cylinder at three months. The most frequent complication was corneal edema lasting at least one week. With careful preparation, proper patient selection, and meticulous technique, the learning curve for converting from extracapsular surgery to small-incision phacoemulsification does not necessarily increase the complication rate.
从囊外白内障手术转换为小切口超声乳化术不可避免地伴随着一个学习曲线。对一位外科医生使用小切口超声乳化术进行的连续50例手术的学习曲线进行了回顾性分析。评估了相关参数，包括术后8天、3周、3个月和6个月时的视力和散光情况。对前25例手术和随后25例手术的结果进行比较，结果显示仅在术后8天的视力和3个月时的柱镜度数方面存在统计学上的显著差异。最常见的并发症是角膜水肿持续至少一周。通过精心准备、合理选择患者以及细致的操作技术，从囊外手术转换为小切口超声乳化术的学习曲线不一定会增加并发症发生率。
