Long-term outcome of scleral-sutured posterior chamber intraocular lens
Reviewed by Jonathan Chan

This is a retrospective review of 392 consecutive cases in 349 patients who had scleral-sutured intraocular lens (IOL) due to aphakia, subluxated or luxated IOL, over a 10-year period in one centre from Barcelona. Preop and postop data were collected including the scleral flaps features, Prolene or Mersilene suture material used and IOL used. Twenty-five eyes required a second surgery due to suture breakage (mean 40.2 +/-39.6 months after first surgery) and three needed a third operation. Younger patients (<40yo), the use of a combination of Prolene and Mersilene sutures and using one flap were found to have higher risk of suture breakage after a 10-year follow-up. A higher tendency of suture rupture (11.76%) was seen in those patients with an axial length (AL) >24.5mm. The probability of survival of the scleral-sutured IOL at 10 years after surgery was 0.79. The authors concluded that this procedure is safe and effective. The limitations of the study are the retrospective nature, no control group, low rate of myopic eyes and the dropped-out during the follow-up period.
