Abstract Details

Purpose:

To review the rates and timing of clinically significant posterior capsular opacification (PCO) following routine cataract surgery in highly myopic patients and to see if capsular tension rings (CTR) make a difference. Clinically significant PCO has been defined as PCO requiring Nd: YAG laser capsulotomy.

Setting:

District general hospital in Swindon, UK. Routine day case surgeries performed between April 2004 and April 2014.

Methods:

Retrospective case note review of 242 eyes from 161 patients that underwent routine cataract surgery. Patients were selected from the theatre logbook entries in which records of IOL implants and CTR use are kept. Patients were included if they had an IOL implant power of 15.0 D or less. Patients with major intraoperative complications were excluded. The patients' notes were then reviewed assess if and when they developed clinically significant PCO, requiring YAG capsulotomy.

Results:

No. of eyes requiring YAG capsulotomy in CTR group=11 (7.9%), in No CTR group=15 (14.5%), p=0.11. Kaplan- Meier Survival curve for YAG capsulotomy rates in each group showed that No CTR group tend to develop clinically significant PCO earlier than the CTR group. At 4 years, survival without YAG capsulotomy was 86% in the No CTR group compared to 96% in the CTR group.

Conclusions:

This is a well populated cohort study that looks at how CTR affects postoperative PCO rates in highly myopic patients. CTR appears to delay the onset of clinically significant posterior capsular opacification, a pattern which has been established in the past.
