Abstract:
Purpose:To evaluate the prevalence of intraocular lens rotation (IOL) and related factors during combined vitrectomy and cataract surgery.
Methods:A university hospital, non-comparative pilot study. The medical records of patients who underwent combined vitrectomy and cataract surgery were retrospectively investigated. Surgical videos were analyzed to observe the degree and timing of rotation of IOL during vitrectomy. Scleral indentation and peripheral vitrectomy were started from 6 o’clock of the eyeball and proceeded counterclockwise, and the presence of rotation was defined when IOL rotated more than 2 hours (60 degrees).
Results:A total of 181 eyes were enrolled in this study, and the rotation of IOL occurred in 13 eyes (7.2%). IOL rotation was observed in 11 out of 117 eyes (9.4%) using 1-piece IOL and 2 out of 64 eyes (3.1%) using 3-piece IOL, and the difference was not significant. The direction of IOL rotation was counterclockwise in 11 eyes (84.6%) and rotated during peripheral vitrectomy and scleral indentation in 12 eyes (92.3%).
Conclusions:Since the rotation of IOL may occur during combined vitrectomy and cataract surgery, the axis of astigmatism should be checked at the end of the operation when using toric IOL.
