SURGICAL RESULTS OF DROPPED NUCLEUS OR IOL

Abstract

PURPOSE: To evaluate visual outcome of patients who underwent pars plana-vitrectomy for dropped nucleus or IOL (IOL). METHOD: This prospective study was performed on patients who underwent pars-plana vitrectomy for dropped nucleus or IOL. Data on demographics, preexisting eye condition, surgery details of cataract and vitrectomy, presenting symptoms, interval between cataract surgery and vitrectomy, secondary IOL implanted or not, details of follow-up visits, and postoperative complications were noted. The corrected VA, IOP (IOP), SLE (SLE) and fundus evaluation was done during each visit and was included in statistical analysis. RESULTS: Out of the 56 patients, 40 cases following cataract surgeries, included 20 cases of nucleus drop and 20 cases of IOL drop. In post-traumatic group, 13 cases were of nucleus drop and 3 cases of IOL drop. All the patients had undergone 3 ports standard pars plana-vitrectomy with or without secondary IOL implantation. ACIOL in 22 cases, SFIOL in 8 cases, while 26 patients were kept aphakic. Out of 56 patients 32.14% patient had VA (VA) of more than or equal to 6/18, 32.14% with VA <6/18 but >6/60 and 35.71% had VA <6/60. Mean post-operative VA of post-operative group was 1.17 and posttraumatic group was 1.49. Major cause for poor visual outcome included corneal decompensation (21.42%), secondary glaucoma (5.35%) and RD (RD)(1.78%). CONCLUSION: Dropped nucleus or IOL following cataract surgery or trauma is a severe complication, but appropriate and timely management can restore VA.
