PASCAL (Pattern-Scanning Laser) is a retinal photocoagulation laser system — originally developed by OptiMedica and now distributed by Topcon.
It is designed for retinal and choroidal laser therapy — including treatment of vascular and structural retinal diseases, diabetic retinopathy, macular edema, retinal tears/detachments, and even glaucoma-related procedures (e.g. trabeculoplasty / peripheral iridotomy depending on modules).
⚙️ Key Features & Technical Aspects
PASCAL uses a pattern-scanning method: instead of delivering single laser spots one at a time, it can deliver predefined patterns — arrays, lines, arcs, grids, etc. with a single foot-pedal press.
Pulse duration is much shorter than traditional lasers — typically 10–20 milliseconds, compared with conventional 100–200 ms.
Delivery speed is high — for example, up to ~ 56 spots in ~ 0.6 seconds, enabling a fast pan-retinal photocoagulation (PRP) in a single session.
Adjustable spot sizes / patterns: single-spot or pattern (square arrays, macular grids, arcs, etc.) depending on indication.
More advanced versions support sub-threshold (micropulse / low-fluence) treatment and safety-oriented protocols — reducing collateral damage to retina, minimizing discomfort, and improving patient tolerance.
✅ Advantages
Faster treatment time compared with conventional photocoagulation — reduces patient chair time and improves throughput.
Less discomfort for patients, thanks to shorter pulses, less heat diffusion, and more precise energy delivery.
High precision and repeatability — pattern delivery ensures uniform spacing and consistent burns, improving treatment reproducibility.
Flexibility — can treat a wide range of retinal/choroidal diseases, from diabetic retinopathy to vascular occlusions, macular edema, peripheral retinal lesions, and more.
Modern safety & retina-friendly protocols — sub-threshold / low-fluence treatments minimize collateral damage, which is beneficial especially near macula or in repeated treatments.
Fully tested and in excellent condition — ready for use in any clinic or hospital setting.
