Experimental: FS Laser Surgery
For femtosecond laser-assisted cataract surgery (FS Laser Surgery), subjects will receive capsulotomy, lens segmentation and, at investigator discretion, lens softening using the OptiMedica Catalys™ Precision Laser System (Catalys System)
|
Procedure: FS Laser Surgery
The Catalys System is an ophthalmic surgical laser system intended for use in cataract surgery. The intervention consists of the both surgery and the use of the device.
