结局指标
主要结局
Best corrected visual acuity
时间窗: 1 month after capsular tension ring and intraocular lens implantation (cataract surgery) using capsular tension ring
Visual acuity measurement using refractive error correction
refractive error
时间窗: 1 month after capsular tension ring and intraocular lens implantation (cataract surgery) using capsular tension ring
Autokeratometry (KR-7100; Topcon, Tokyo, Japan) and manifested refraction were performed to examine refractive errors
Anterior chamber depth
时间窗: 3 months after capsular tension ring and intraocular lens implantation (cataract surgery) using capsular tension ring
obtained with a Scheimpflug imaging system (Pentacam; OCULUS Optikgeräte GmbH, Wetzlar, Germany)
Ocular aberrations
时间窗: 1month after capsular tension ring and intraocular lens implantation (cataract surgery) using capsular tension ring
measured using the ray-tracing aberrometer (iTrace, Tracey Technologies, Houston, TX, USA) at a pupil size of 5 mm in mesopic conditions, without pharmacologic dilatation
