title: PREVENTING PUPILLARY CAPTURE AFTER VITRECTOMY AND TRANSSCLERAL FIXATION OF AN INTRAOCULAR LENS: Iridotomy Using a Vitrectomy Probe.
abstract: OBJECTIVE
  To investigate the effects of concurrent iridotomy using a vitreous cutter probe on the prevention of pupillary capture in patients undergoing transscleral fixation of intraocular lens implantation.
  
  
  METHODS
  A total of 79 eyes from 79 patients, who underwent transscleral fixation of intraocular lens without preexisting vitreoretinal disorders and who were followed up for 6 months were included. Subjects were divided into a noniridotomy group (51 eyes) and an iridotomy group (28 eyes). After conventional 23-gauge vitrectomy and transscleral fixation of intraocular lens implantation in all patients, 28 patients underwent concurrent iridotomy intraoperatively. The patients were followed up to evaluate the incidence of surgery-related complications, including pupillary capture.
  
  
  RESULTS
  There were no statistically significant differences in the preoperative demographic findings between the two groups (all P > 0.05). There was a significant difference in pupillary capture in 15 eyes (29.4%) of the noniridotomy group, compared with 1 eye (3.6%) of the iridotomy group (P = 0.007). There were no differences in postoperative best-corrected visual acuity between the two groups, and no iridotomy-related complications were observed.
  
  
  CONCLUSIONS
  Concurrent iridotomy using a vitreous cutter probe is an easy, rapid, and effective procedure to prevent possible pupillary capture after combined vitrectomy and transscleral fixation of intraocular lens implantation.
