ABSTRACT

Purpose: To demonstrate the utility, safety and performance of the Malyugin ring during phacoemulsification in patients with poor pharmacologic mydriasism synechiae and intraoperative floppy iris syndrome.
Patients and Methods: Phacoemulsification was performed in 21 eyes of 19 patients with poor pupil dilation, using the Malyugin ring to maintain mechanical mydriasis during surgery; all intraoperative events and complications were registered.
Results: The safety of the Malyugin ring was reproducible in all cases, there were no significative complications associated with its use. A constant mydriasis of 6 mm was maintained without the interference of the ring during surgery. In 8 patients were observed micro tears in the pupil sphincter and in 3 patients were observed micro bleedings.
Discussion: The Malyugin ring is a useful device for the anterior segment surgeon, facilitating the development of phacoemulsification in patients with small pupils, improving the postoperative results and avoiding common complications in such cases.
