Use of Malyugin Pupil Expansion Ring in Femtosecond Laser-assisted Cataract Surgery

Nada Jiraskova, Pavel Rozsival and Jan Lestak

Purpose: To describe a technique that allows performing femtosecond laser-assisted cataract surgery with the LenSx laser (Alcon) in patients with poor or non dilating small pupils.

Methods: Case report describing new surgical technique.

Results: The primary and secondary incisions were made manually and the anterior chamber was filled with ophthalmic viscosurgical device (OVD). The Malyugin pupil expansion device (Microsurgical Technology) was inserted through the main port incision via the injector. The OVD was removed and all incisions were hydrated. Laser capsulorhexis and lens fragmentation was performed after docking. Subsequent phacoemulsification, intraocular lens (IOL) implantation and the Malyugin ring removal was performed in the usual fashion.

Conclusions: Use of the Malyugin ring is a reliable and stable method of maintaining an adequate surgical pupil diameter both for femtosecond laser assisted capsulotomy and lens fragmentation with Lenx laser and subsequent phacoemulsification and IOL implantation.
