LISBON, Portugal — A new software program for excimer-laser correction of presbyopia is designed to provide patients with near and far vision while retaining depth perception and minimizing contrast loss, according to laser manufacturer Schwind eye-tech solutions.
The Presby-CAM software is based on what the company calls a balanced multifocal monovision principle. The program creates an oblate multifocal cornea in one eye and a prolate multifocal cornea in the fellow eye, according to a Schwind press statement released here at the European Society of Cataract and Refractive Surgeons meeting.
“The central development goal of the Presby-CAM was to provide refractive surgeons and their patients with a satisfiable therapeutic option for the treatment of presbyopia in corneal laser surgery,” Rolf Schwind, president and chief executive officer of the company, said in the statement.
According to the company, one eye is optimized in the center for distance vision and in the periphery for near vision through the creation of a negative spherical aberration on the cornea. The software produces the opposite effect in the other eye, allowing the two eyes to provide binocular vision.
The Presby-CAM is designed for use in Schwind systems with the Esiris excimer laser, the company said.
