Abstract
PURPOSE: To evaluate changes in intraocular pressure (IOP) after surgical correction of spontaneous late in-the-bag intraocular lens (IOL) dislocation. SETTING: Two tertiary referral hospitals in Spain. DESIGN: Retrospective case series. METHODS: Cases of in-the-bag IOL dislocation from 2004 to 2014 were included. The IOP and grade of IOL dislocation were correlated before surgery. The IOP and number of drugs to treat glaucoma were compared before and after surgery in cases with more than 6 months of follow-up in the whole group and in separate groups according to the technique used to correct IOL position. RESULTS: This study evaluated 134 eyes. The mean IOP at diagnosis decreased significantly as the grade of dislocation increased (P = .012). After surgery, the mean corrected distance visual acuity improved significantly and the mean IOP decreased significantly after surgery in all groups (both P = .000); the IOP decrease was significantly more pronounced in the glaucoma group than in the entire sample (P = .011). No statistically significant differences were detected in preoperative or postoperative IOP between the surgical technique groups. There was no significant increase in the number of drugs to treat glaucoma (P = .064). CONCLUSIONS: There was a significant trend toward a decrease in IOP as the grade of IOL dislocation increased. The IOP decreased significantly after surgical management of in-the-bag dislocated IOLs without a significant increase in number of drugs to treat glaucoma. The decrease was independent of the technique used to correct IOL dislocation.
