- pseudoexfoliation syndrome
- intraoperative floppy iris syndrome
- ectopia lentis
Correct Answer: ectopia lentis
The Malyugin ring is a device to enlarge a small pupil and/or stabilize an atonic iris. This may be necessary in patients with pilocarpine treatment, pseudoexfoliation, and IFIS. Pupillary dilation is usually not an issue in ectopia lentis.
