Title

Automated Capsulotomies without Femtosecond Laser

Purpose	To determine the efficacy, safety and predictability of a new device, the Zepto (Mynosys,Inc), for capsulotomies during cataract surgery. The Zepto is supposed to deliver automated, consistant, round capsulotomies.
Methods	We reviewed 70 eyes of 37 patients who had cataract surgery in our Center. All cases had an anterior chamber deeper than 2.5mm (as requested by the procedure) and were implanted with a multifocal IOL. 33 patients had the Zepto procedure in both eyes, 4 patients had the Zepto procedure in their dominant eye only, as the first eye was already done with a manual capsulotomy. All eyes were free of any ocular disorders, such as macular degeneration, glaucoma, diabetes, etc. Emmetropia was targeted in all cases. Barrett Formula from the IOLMaster (Carl Zeiss, Germany) was used in all cases. Surgery was performed by the same surgeon (BM). Distance visual acuity, nearby visual acuity, centration of the IOL, overlapping of the IOL by the anterior capsule, patient satisfaction, were recorded at 1D, 1M and 3M.
Results	At 1D, all eyes had a UCVA of 20/25 or better, at 1M, UCVA of 20/20 or better, idem at 3M. Overlapping of the lens was complete in 68 eyes; two eyes had an incomplete overlapping of the lens, one due to a wider capsulotomy (error in the procedure), the other due to a tear in the anterior capsule during phacoemulsification. No other complications occurred. Centration of the lens was estimated correct in all cases.
Conclusion	The Zepto device realised a consistant, round capsulotomy, centrated on the visual axis. The procedure cost is reduced compared to the FemtoLaser and it does not impair the operative flow.
