Use of Malyugin Pupil Expansion Ring in Femtosecond Laser-assisted Cataract Surgery
نویسندگان
چکیده
Non dilating narrow pupils are a challenge for cataract surgeons. The Malyugin pupil expansion device (Microsurgical Technology) has several advantages over traditional iris retractor hooks or other pupil dilating devices [1]. This is a disposable, square shaped implant, made of polypropylene with four circular scrolls that engage the pupillary margin at equidistant points providing a balanced stretch. It can be implanted and explanted through microincision with an injector system [2,3].

To the Editor: The use of the femtosecond laser in cataract surgery has increased exponentially since its introduction in 2009, and it is beneficial in routine and challenging cases.1 However, one disadvantage is the possible induction of significant miosis, which has been reported in up to 32% of eyes.2 Some factors have been shown to decrease the incidence of this complication, such as advanc...

We describe a surgical technique for management of zonular instability and pupillary miosis using a pupil expansion device (Malyugin ring) in patients who need cataract surgery. In this technique, the pupil expansion device is first used in the usual fashion. After a capsulorhexis has been created, lateral scrolls of the pupil expansion device are released and repositioned to entrap both the an...
