Abstract
PURPOSE: To report the clinical outcome of patients undergoing cataract surgery after one or repeated intravitreal injections of triamcinolone acetonide as treatment of intraocular neovascular or oedematous diseases. METHODS: The interventional clinical case series study included all patients (n=22) who presented with cataract which had progressed after a single or repeated intravitreal injection of 25 mg of triamcinolone acetonide as treatment of exudative age-related macular degeneration (n=18) or diffuse diabetic macular oedema (n=4). Duration of the follow-up period was 3.76+/-4.99 months. With topical anaesthesia, the patients underwent standard cataract surgery including clear cornea incision, phakoemulsification and aspiration of the lens nucleus and cortex, and implantation of a foldable posterior chamber lens. The main outcome measures were frequencies of capsular rupture, vitreous loss, postoperative infectious endophthalmitis, secondary cataract, and decentration of the intraocular lens, visual acuity and intraocular pressure. RESULTS: Intraoperative dialysis of the lens zonules occurred in one (4.5%) eye and resulted in a loss of vitreous. Secondary cataract leading to Nd : YAG laser capsulotomy was observed in one (4.5%) eye. An optically significant decentration of the IOL or infectious endophthalmitis was not encountered in any patient. Visual acuity increased from 0.11+/-0.10 to 0.13+/-0.94 during the follow-up. Within 1 week after surgery, intraocular pressure was in the normal range in all the eyes. CONCLUSIONS: Cataract surgery after single or repeated intravitreal injection of 25 mg of triamcinolone acetonide does not harbour a markedly elevated frequency or a markedly changed profile of surgical complications.
