he PASCAL^® (Pattern Scan Laser) Photocoagulator is a fully integrated pattern scan laser system designed to treat retinal diseases using a single spot or a predetermined pattern array of up to 56 spots.

The PASCAL technology platform is based upon the use of a  proprietary, semi-automated, pattern generation method employing short 532 nm laser pulses. These laser pulses are delivered in a rapid predetermined sequence resulting in improved precision, safety, patient comfort, and a significant reduction in treatment time compared with single-spot photocoagulation.

Pre-clinical animal studies, as well as initial pilot studies in humans indicate that in addition to reducing treatment duration for typical patients with proliferative diabetic retinopathy, the number of sessions may also be reduced.
