متن کاملUse of Malyugin Pupil Expansion Ring in Femtosecond Laser-assisted Cataract Surgery
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 ...
