[Malyugin ring--an alternative in the treatment of a miotic pupil]

Small pupil and Intraoperative Floppy Iris Syndrome (lFIS) has always been a challenge in cataract surgery. Iris dilation and mechanical stabilization can be achieved by using intraoperative iris retractors, preferably before capsulorhexis. Malyugin ring is a mechanical iris expansion device, which presents many advantages (gently relaxes the iris tissue, implants easier and less traumatic). The disadvantages of using Malyugin ring consists primarily in the high cost and in an increased duration of surgical procedure.
