The Perfect Capsulotomy – one less variable in refractive predictability

ZEPTO™ is a novel capsulotomy device with a disposable handpiece and tip that produces a quick, elegant, round capsulotomy in milliseconds. The tip consists of a miniature, transparent, soft silicone suction cup that houses a circular nitinol capsulotomy element, which has been refined at the micron scale to enable uniform 360-degree capsule cutting.

Quick & Easy

Nitinol is a superelastic alloy, meaning the tip can be deformed in order to enter gently through a clear corneal incision, after which it assumes its original round shape within the anterior chamber. Complete, round capsulotomies are accomplished in a few milliseconds.

Safe & Effective

FDA Clinical Trial completed enrollment in December 2016. Safety testing has included temperature measurements using thermocouples in the eye during ZEPTO capsulotomy. Only very brief transient temperature changes of 1° to 2°C lasting several seconds were noted adjacent to the ZEPTO tip and the corneal endothelium. Zonular safety has also been investigated using Miyake-Apple imaging during ZEPTO capsulotomy in rabbit eyes. Very little stress on the zonules was observed during application of suction, capsulotomy, and suction release. A complete assessment of safety and performance has been performed in live rabbits, which showed no corneal endothelial cell damage, inflammatory response, or gross and microscopic tissue damage due to ZEPTO use.

Unique Features

ZEPTO capsulotomies have a capsular edge tear strength 3 to 4 times greater than that of continuous curvilinear capsulorhexis and femtosecond laser capsulotomies. ZEPTO allows intraoperative capsulotomy centration on the patient’s visual axis for an optimized outcome.
