Retrospective analysis of surgical strategies for lens subluxation / 国际眼科杂志(Guoji Yanke Zazhi)

ABSTRACT

@#AIM:To analyze the effectiveness and safety of different surgical strategies for cataract combined with subluxated lens. <p>METHODS: This is a retrospective study. Data are acquired from patients who diagnosed with cataract combined with subluxated lens between November 2018 to May 2019 in the ophthalmological center of the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine. There are 11 eyes in 11 patients(9 males and 2 females), 10 eyes were caused by trauma and 1 eye was unknown. Cataract combined with subluxated lens were treated with different surgery procedures according to the degree of dislocation. Four eyes with lens dislocation larger than 270° underwent intraocular lens suspension; Four eyes with lens dislocation about 180° underwent IOL and tension ring implant in capsular, at the same time, the iris hook was hooked to the lens capsule bag and fixed to the sclera. Three eyes with lens dislocation less than 180° underwent IOL implantation combined with 5-0 polypropylene suture, iris hook was also hooked to the lens capsule bag and fixed to the sclera. If the anterior chamber has vitreous prolapse, anterior vitrectomy was performed. Best corrected visual acuity(BCVA)and intraocular pressure(IOP)were observed before and after surgery. <p>RESULTS: All eyes were successfully implanted with intraocular lens(IOL). Best corrected visual acuity(LogMAR)increased from 0.77±0.26 to 0.35±0.28. Mean IOP decreased from 24.33±13.55 to 13.85±3.80mmHg. No intraoperative complications occurred in all cases.<p>CONCLUSION: In the treatment of lens dislocation with cataract, individualized surgical plan and flexible treatment measures can make cataract surgery safe and effective.
