To explore the learning curve for ophthalmologists at the start of laser peripheral iridectomy (LPI) training.
The learning curve of 4 doctor groups without previous LPI experience was studied. Three main parameters of LPI were reviewed: total energy, argon energy and neodymium-doped yttrium aluminum garnet (Nd:YAG) energy. Procedures were evaluated in cohorts of 20 cases to identify the turning points of the three variables.
There was no significant difference in terms of age or eye among the 4 doctor groups. There were stable trends on the learning curve for the Doctor A and C groups regarding total energy and argon energy. In addition, the turning points on the learning curve were determined after the 20 procedure for the Doctor B and D groups regarding total energy and argon energy. Moreover, the Nd:YAG energy was relatively stable since the first procedure.
It requires approximately 20 procedures for a beginner to reach a turning point on the learning curve regarding LPI. It can serve as a point of reference or guideline for training beginners to perform LPI.
探讨眼科医生在开始激光周边虹膜切除术（LPI）培训时的学习曲线。
研究了4组无LPI经验的医生的学习曲线。回顾了LPI的三个主要参数：总能量、氩激光能量和掺钕钇铝石榴石（Nd:YAG）激光能量。以20例为一组对手术进行评估，以确定这三个变量的转折点。
4组医生在年龄或眼睛方面无显著差异。A组和C组医生在总能量和氩激光能量的学习曲线上呈稳定趋势。此外，B组和D组医生在总能量和氩激光能量方面，在完成20例手术后确定了学习曲线上的转折点。而且，自首次手术以来，Nd:YAG激光能量相对稳定。
初学者在LPI学习曲线上达到转折点大约需要20例手术。它可为培训初学者进行LPI提供参考或指导。
