Abstract:

【Abstract】Objective To analyze the effect of combined surgical approaches including cataract extraction, intraocular lens (IOL) and capsular tension ring (CTR) implantation as the main method for secondary glaucoma due to lens subluxation. Design Retrospective case series. Participants 12 patients aged 62.3±6.9 years old of secondary glaucoma due to lens subluxation from July 2011 to September 2013 in Beijing Tongren Hospital were included. Methods The medical records before and after the surgery were retrospectively analyzed. All cases were implanted IOL in the bag, 11 cases were performed phacoemulsification cataract extraction, one case extracapsular cataract extraction, 6 cases CTR, 7 cases goniosynechialysis with viscoelastic, 5 cases trabeculectomy, one case transscleral cyclophotocoagulation, 4 cases pars plana vitreous water bag aspiration during the surgery. The mean follow-up was 13.3±10.0 months. Main Outcome Measures Visual acuity, intraocular pressure (IOP) and complications. Result The visual acuity in last follow up was improved in 8/12 patients, the improved lines of visual acuity was 4.9±2.8. Unchange of visual acuity was in 3/8 patients. All patients (100%) got control of IOP (< 21 mmHg) without drug at the final visit. No serious complications occurred during or after the operation. Conclusion The finding of small sample size and short-term follow-up of this article demonstrated that combined surgical approaches including cataract extraction combined with IOL and CTR implantation is safe and effective for secondary glaucoma of lens subluxation.
