Evaluation of Toric Intraocular Lens(IOL) Combined With Capsular Tension Ring(CTR) in Patients With Cataract Combined With High Myopia
Sponsor: Shanghai 10th People's Hospital
Summary
The objective of this study is to evaluate the postoperative visual quality and IOL stability in patients with cataracts and high myopia who have undergone surgery using astigmatism-correcting IOLs in conjunction with tension rings.It is a non-randomised retroprospective cohort study. Patients with high axial myopia (AL ≥ 26 mm) who underwent cataract phacoemulsification combined with toric IOL(Acrysof SN6ATY IQ toric IOL, Alcon, Alcon Laboratories, Fort Worth, Texas, USA) implantation from October 2020 to September 2023 at the Shanghai Tenth People's Hospital are selected. According to the usage of CTR, all patients will be divided into CTR group and control group, with a minimum follow-up of 3 months.Each patient underwent a comprehensive preoperative examination and ophthalmological examinations at the outpatient clinic 1 day, 1 week, 1 month, and 3 months postoperatively.Statistical analysis will be conducted using SPSS 26.0 statistical software.

Interventions
intraoperative implantation of Capsular Tension Ring
The Capsular Tension Ring(ACPi-11; Bausch + Lomb, Rochester, New York, USA) is a device made of PMMA with blunt-tipped eyelets at its ends. It can be inserted at any point during cataract surgery, following the creation of a strong anterior capsulotomy via capsulorhexis
