Abstract:  Objective To study the surgical methods and their safety of in-the-bag IOL subluxation. Design Retrospective case series. Participants 19 cases (19 eyes) were enrolled with the diagnosis as in-the-bag IOL subluxation in Beijing Tongren Eye Center from Feb 2009 to Feb 2013. Methods Review the above cases. IOL exchange with suture fixation surgery or transcapsule IOL suture fixation reposition surgery was performed according to the IOL type and the severity of the IOL subluxation. Main Outcome Measures Surgical method, visual acuity, postoperative complications. Results All 19 cases went through surgical treatment smoothly: 5 cases (26.3%) by IOL exchange with suture fixation surgery in which the dislocated IOL was removed and replaced with transscleral sutured posterior chamber IOL; other 14 cases (73.7%) by transcapsule IOL suture fixation reposition surgery in which the dislocated haptics were sutured to the sclera. The postoperative follow-up lasted for 5 to 41 months. At the last visit, postoperative visual acuity ≥0.3 in all 19 cases, ≥0.8 in 8 cases (42.1%). Mild hyphema or vitreous hemorrhage occurred in 7 cases (36.8%) in the first day after surgery. Hypertension occurred in 3 cases (15.8%) during the first week after surgery. IOP all went back to normal after eye drop treatment. Slight decentration of IOL occurred in 3 cases (15.8%). Slight tilt of IOL occurred in 4 cases (21.1%). These 7 cases were remained untreated with observation. Conclusion IOL exchange with suture fixation surgery and transcapsule IOL suture fixation reposition surgery are effective and safe surgical solutions to postoperative in-the-bag IOL subluxation.
