Cataract surgery is a common procedure these days, yet current methods still require the surgeon to exercise manual precision. Santa Clara, CA-based OptiMedica Corp. claims that its newly CE marked Catalys Precision Laser System will help increase the precision of cataract procedures with its combination of a femtosecond laser and integrated optical coherence tomography (OCT).
The Catalys’ OCT system automatically detects the surfaces of the patient’s lens and cornea to ensure safe and accurate delivery of laser pulses, and the company’s proprietary Liquid Optics Interface maintains a large clear optical path for the OCT imaging, laser pulse delivery, and real-time video.
From the press release:
With Catalys, physicians have the opportunity to perform cataract surgery with an unsurpassed level of accuracy. The system is currently CE mark approved to deliver capsulotomy (a circular incision in the lens capsule) and lens fragmentation (segmenting and softening of the lens to prepare for removal), with CE mark approval for corneal incisions anticipated in the near future. A clinical study has demonstrated that Catalys delivers marked improvement over manual surgical technique, with key metrics including:
• Capsulotomy size, as measured by deviation of capsule diameter from intended target. The average deviation in capsule diameter with Catalys was only 29 microns, as compared to an average deviation in the manual technique of 337 microns;
• Capsulotomy shape, with a score of 1.0 representing perfect circularity. Capsulotomies delivered with Catalys achieved almost 95 percent circularity, with very little spread in outcomes across all eyes. In the manual group, only 77 percent circularity was achieved, with a larger spread in results;
• Capsulotomy centration. Capsulotomies performed with Catalys were within only 77 microns of perfect centration relative to the dilated pupil; and,
• Ease of lens fragmentation and disassembly. With Catalys, cumulative dissipated energy (CDE) during ultrasound phacoemulsification was reduced by approximately 40 percent.
