A disposable device using precision pulse technology (Zepto, Mynosys Cellular Devices) provides a safe and reliable technique for automated anterior capsulotomy in eyes undergoing cataract surgery, according to the findings of a prospective investigation.
The size, consistency, and clinical strength of the capsulotomy created with the device was evaluated in a series of 38 cases performed by three experienced cataract surgeons—Gabriel Quesada, MD, Kevin Waltz, MD, OD, and Vance Thompson, MD—at Clinica Quesada, San Salvador, El Salvador.
The procedures were performed under topical anesthesia with monitored anesthesia care, and patients were scheduled to return for follow-up at day 1, month 1, month 3, and month 6 after surgery.
A 360° free-floating capsulotomy with a diameter ranging from 5.1 to 5.3 mm was created in all eyes, and the capsulotomies were consistently round and well centered.
No cases of anterior capsular tear occurred during phacoemulsification. Postoperative follow-up showed all capsulotomies remained intact, well centered, and free from phimosis.
“Anterior capsulotomy is a critical step for successful cataract surgery,” said Dr. Quesada, medical director, Clinica Quesada. “Our experience—which represents the initial clinical evaluation of precision pulse capsulotomy—indicates that the device provides excellent results, including in challenging cases with very hard or white cataracts, small pupils, and zonular dialysis.”
