PURPOSE: To assess the results of iris suture fixation of subluxated intraocular lenses. DESIGN: Retrospective study. METHODS: This was a nonrandomized chart review of eyes with subluxated intraocular lenses that underwent iris suture fixation at an academic institutional care center. Seventy-two eyes of 67 consecutive patients were included. The following cases were excluded: posterior dislocations necessitating pars plana vitrectomy; secondary implantations for aphakia; and iris suture fixation at primary cataract extraction. Main outcome measures included visual acuity improvement, surgically induced astigmatism, and postsurgical complications. RESULTS: The mean follow-up duration was 16.64 ± 24.37 months (median = 4.03 months). All patients had preoperative monocular diplopia or unstable vision attributable to the subluxated intraocular lenses, and 40.3% of them required aphakic correction. There was an overall improvement in best-corrected visual acuity from a mean preoperative logMAR 0.35 ± 0.32 (Snellen equivalent∼20/45) to logMAR 0.21 ± 0.25 (20/32, P = .001). There was no significant change in astigmatism secondary to the surgery. The mean difference in preoperative keratometry readings was 1.6 ± 1.07 diopter (D), whereas the mean postoperative manifest refraction astigmatic error (vertexed to the corneal surface) was 1.29 ± 0.92 D (P < .02). Re-subluxations occurred in 7 eyes during follow-up; the majority of these eyes underwent repeat fixation. Most (93.55%) intraocular lenses were stable and centered at the final follow-up. Glaucoma developed in 2 eyes postoperatively. CONCLUSIONS: Iris suture fixation of subluxated intraocular lenses was efficacious for the eyes included in this study, and it led to long-term stability of the intraocular lenses in 93.55% of cases.
