Chung’s swing technique: a new technique for small-incision lenticule extraction

摘要

Background To introduce the Chung’s swing technique for small-incision lenticule extraction (SMILE). Methods A total of 112 eyes of 56 patients were included in this study. Patients were divided into two groups: 52 eyes of 26 patients were treated with SMILE using a traditional method (traditional group) and 60 eyes of 30 patients were treated with SMILE using the Chung’s swing technique (swing group). Results At 1?month postoperatively, all eyes in both groups had an uncorrected distance visual acuity of 20/20 or better. The efficacy indices were 1.09?±?0.17 and 1.02?±?0.11 ( p =?0.492), and the safety indices were 1.12?±?0.14 and 1.09?±?0.15 ( p =?0.537), for the traditional and swing group, respectively. All eyes in both groups underwent successful lenticule extraction; all lenticules were intact and complete. The mean lenticule extraction times were 48.67?±?4.9 and 39.8?±?5.53?s, for the traditional and swing group, respectively ( p Conclusions The Chung’s swing technique is efficient for lenticule separation and extraction. Our study results showed good clinical outcomes. Trial registration Trial registration number: KCT0001978 . Registered 22 July 2016. Retrospectively registered.
