[Clinical analysis for retinal detachment after cataract surgery in high myopic eyes]

Abstract

Aim: To analyze the clinical characteristics, incidence and risk of retinal detachment (RD) after cataract surgery and posterior chamber intraocular lens implantation in high myopic patients.

Methods: The medical records of 146 high myopic patients (232 eyes) who underwent cataract surgery and posterior chamber intraocular lens implantation were studied retrospectively. The development of RD was followed up over a 3-year period, and its characteristics were determined. All of the eyes received a comprehensive ophthalmological examination, including best-corrected visual acuity measurements, a dilated fundus examination and axial length measured by A-scan ultrasonography.

Results: RD developed in 15 eyes of 15 patients. All the 15 eyes needed vitreo-retinal surgery. The mean interval between cataract surgery and the development of RD was 10 +/- 9 months (range 0.5-32 months). The visual results of the eyes after anatomical successful vitreo-retinal surgery ranged from finger count/10 cm to 0.06. 80% (12/15) of the eyes had a worse vision after the surgery than that before cataract surgery. Posterior capsular tear were associated significantly with RD (P < 0.01). Approximately 60% (9/15) of retinal detachment was attributable to posterior capsule tear during cataract surgery.

Conclusion: Incidence of RD in high myopic patients after cataract surgery was 6.4%. RD was the potentially serious complication and tended to develop more frequently in eyes with posterior capsular rupture during cataract surgery. It is crucial to examine retinal status after cataract surgery and to have a close follow-up to prevent retinal complications, especially for patients with posterior capsular disruption.
