Abstract

Purpose : To assess the efficacity, the pain, the duration and the safety of a navigated panretinal photocoagulation (PRP) session using non contact widefield objective compared to the conventional contact lens technique.

Methods : Twenty eyes of ten naives patients requiring bilateral PRP for diabetic retinopathy were included. Both eyes of the same patient were treated the same day using a navigated laser (Navilas 577s, OD-OS). The treatment of one eye was performed conventionally using a wide field contact lens (Ocular Mainster PRP 165) and the same area of the other eye was treated using the non contact objective with the same parameters (power, exposure time, number, size and spacing of the spots). For each eye, the duration of the session and the pain, measured a visual analogic scale, were compared. The number of visible spotsafter the treatment using each technique was assessed on color and autofluorescence ultrawidefield picture (Optos, Dunfermline, UK). The occurrence of undesired laser spots at the posterior pole was assessed.

Results : A mean of 1012 (872-1356) spots with a mean power of 358mW (300-450mW) were delivered. The time, the pain and the number of visible spots after the treatment were not significantly different using the two different techniques. All spots were delivered at the desired location and no side effects were reported.

Conclusions : Our study suggests that the non contact objective is an effective and safe way to perform PRP treatments.
