Phacoemulsification Combined With Intraocular Lens And Capsular Tension Ring Implantation In Treating Glaucoma Caused By Traumatic Subluxated Lens

Purpose To explore the long-term clinical efficacy and safety of phacoemulsification combined with intraocular lens (IOL) and capsular tension ring (CTR) implantation in treating secondary glaucoma caused by traumatic subluxated lens.Methods This retrospective analysis was carried on 17 patients(17 eyes) with secondary glaucoma caused by traumatic subluxated lens in our hospital from September 2011 to September 2015,who underwent phacoemulsification and IOL and CTR implantation. Followed up from 6 to 24 months. Data on Uncorrected Visual Acuity(UCVA) and Best Corrected Visual Acuity(BCVA) and intraocular pressure(IOP) before treatment and after lweek treatment and after treatment from 6 to 24 months were extracted and analyzed. Date on corneal endothelial cell counting and chamber depth before and after treatment were extracted and analyzed. Analyze the complications during operation and postoperation.Results (1)The preoperative IOP was (35.93±17.25mm2g),the postoperative IOP was (18.96±10.93mmHg),the postoperative IOP from 6 to 24 months was (14.24±3.08mmHg),all were significant differences between each other(p=0.000,p<0.05).②The preoperative UCVA was (HM-0.3),the postoperative UCVA was (0.06-0.6),the postoperative UCVA from 6 to 24 months was (0.05～0.6), all were significant differences between each other(p=0.001,p<0.05). The preoperative BCVA was (0.01-0.8),the postoperative BCVA was (0.1-0.9),the postoperative BCVA from 6 to 24 months was (0.1～1.0). all were significant differences between each other(p=0.005,p<0.05). ③The use of IOP-lowering medication after the surgery compared with preoperative medication reduced significantly (P<0.05).④Anterior chamber depth and corneal endothelium after the surgery compared with preoperative were significant differences(p<0.05).⑤ Complications:vitreous prolapsed in 4case,all of them received anterior vitrectomy. There were not found capsule tearing caused by the overlarge tension. There were no postoperative re-dislocation of the CTR-IOL complex or severely abnormal corneal endothelium.Conclusion CTR implantation in treating glaucoma caused by traumatic subluxated lens is a relatively safe and effective therapeutic method.
