Application of Scleral Fixed Capsular Tension Ring in Surgery for Moderate and Severe Lens Dislocation
Journal: Journal of Clinical Medicine Research DOI: 10.32629/jcmr.v3i1.705
Abstract
Objective — To investigate the effect of phacoemulsification cataract extraction in patients with moderate or severe lens subluxation with scleral fixed capsular tension ring implantation. Methods — A total of 43 patients (47 eyes) with lens subluxation (scope of dislocation exceeds 120 degrees) underwent phacoemulsification cataract aspiration in our hospital from November 2018 to May 2019. During intraoperative injection/aspiration of the lens cortex, the scleral fixed capsular tension ring was put into the lens capsule, and then the capsular tension ring was fixed on the sclera with sutures to summarize the surgical methods and observe the preoperative and postoperative visual acuity. Pentacam anterior segment analysis system and UBM were used to observe the capsular center and record the related complications. Results — There were statistically significant differences in the distribution of corrected visual acuity before and after operation (P<0.01). The fixations stability of MCTR and intraocular lens proved to be in good condition. There was no IOL displacement and no serious complications after 6 months of observation. Conclusion — The scleral fixed pocket tension ring is a safe and effective method for the treatment of moderate and severe lens dislocation, which can improve the surgical safety, prevent intraocular lens deviation and reduce surgical complications.
