The PASCAL (Pattern Scanning Laser) photocoagulator delivers a customizable pattern array of laser spots at 532nm wavelength with a much shorter duration per laser application than standard laser delivery systems. Herein we report our initial clinical experience with the PASCAL photocoagulator for a variety of retinal conditions.
The PASCAL laser photocoagulator was used to apply laser therapy based upon standard indications for treatment. Indications included high risk diabetic retinopathy, macular edema, and retinal tears. The pulse duration ranged from 10 to 20 milliseconds, and the pattern and size of laser matrix applied varied based on the discretion of the treating physician. Clinical outcomes, patient comfort, duration of treatment, and delivery system utility were evaluated.
Clinical outcomes mirrored those expected with similar dose and timing of laser treatment for each given indication. Patients reported a higher level of comfort with the PASCAL system compared to other commercially available laser photocoagulation systems. The treating physicians reported increased efficiency, a rapid learning curve, decreased fatigue during treatment, and an overall favorable impression of the PASCAL system.
The PASCAL laser for retinal photocoagulation may be associated with improved patient and physician satisfaction based on increased efficiency and comfort and potentially improved safety and precision compared with standard single spot laser delivery systems.
