Precise capsulotomies are important to the success of cataract surgery, even more so when implanting specialty lenses.1,2 The latest evolution of ZEPTO® offers unparalleled precision while increasing efficiencies in your OR.
Compared to a CCC, which approximates or does not specify the point of fixation, the ZEPTO® capsulotomy is centered along the visual axis intracamerally using Purkinje images.
Patient fixation is used to determine the true visual axis.
1. Select and use one eyepiece with co-axial light.
2. With the ZEPTO® tip recircularized in the anterior chamber, instruct the patient to fixate on the surgical microscope light coaxial to the selected eyepiece.
3. Identify P1 (and P4) Purkinje images. Position the center of the nitinol ring on P1.
Well-formed capsulotomies with a 360° IOL overlap may encourage a stable IOL position and minimize6:
In a 2018 national cataract survey, patients said their primary concerns were:
