| Abstract
| - Background/aims. The pattern scan laser photocoagulator (PASCAL) is a novel laser device that uses 10-30 ms pulse duration for retina photocoagulation. The aim of this study was to analyse the safety profile of this approach. Methods. This was a retrospective study. We reviewed the clinical records of all laser sessions performed with PASCAL from November 2007 to July 2008. Where there were any complications, we recorded the laser parameters, type, affected retina region, postoperative interval and treatment if required. Results. There were 1301 consecutive cases. Complications included 17 cases of retinal bleeding (1.3%), two cases of choroidal detachment (0.15%) and one case of exudative retinal detachment (0.07%). There was no statistical difference between the laser parameters used in patients with or without complications. Conclusion. The laser parameters for PASCAL are safe. The complications and adverse effects encountered in this series are similar to those reported in other studies.
