More Details




  • Instantaneous capsulotomy
  • Precision centration on the visual axis
  • Automated capsulotomy technology = ease of use
  • Works with small pupils
  • Not affected by corneal scars or irregularities
  • Easy practice adoption
  • Seamless integration into surgical sequence
  • Ideal for difficult cases like weak zonules and dense cataracts


ZEPTO Capsulotomies have a capsular edge tear strength 3 to 4 times greater than that of continuous curvilinear capsulorhexis.

ZEPTO allows intraoperative capsulotomy centration on the patient’s visual axis for an optimized outcome

With ZEPTO, you can perform safe and round capsulotomies under the iris in cases with small pupils


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


FDA Clinical Trial completed enrolment in December 2016. Safety testing has included temperature measurements using thermocouples in the eye during ZEPTO capsulotomy. Only very brief transient temperature changes of 1-2 degree Celsius 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.
