Medication support and features of uveal cataract surgery

Abstract

Purpose. To present the results of complicated uveal cataract surgery using medication treatment schemes and a minimally invasive surgery technique.Materials and methods. The study included 13 eyes of 12 patients with uveitis-associated cataract, who underwent phacoemulsification with implantation of hydrophobic acrylic intraocular lenses. All cases were categorized into two groups with different preoperative treatment. The patients of the group 1 received the intravitreal application of Ozurdex (main group) and in the group 2 subtenon corticosteroids injections in combination with systemic pulse-therapy (the control group). The etiology of the disease was established in 10 patients where relapse-free period was 7.3±2.5 months. Minimization of surgical trauma was provided by the use of vitreoretinal instruments 25-27G, an intraoperative local (step-by-step) pupil dilatation and a gentle posterior capsule peeling. The postoperative follow-up period was from 4 to 22 months. In addition to the standard ophthalmological examination, all patients underwent B-scanning, optical coherence tomography (OCT) on Carl Zeiss Cirrus 5000, and laser flare photometry.Results. The postoperative BCVA increased in all patients (0.47±0.17) and was significantly higher than the preoperative BCVA (0.11±0.1, p<0.05). Reactivation of the inflammation was observed in 3 patients (two – in the control group and one – in the main group); an additional use of Ozurdex implant allowed to stop inflammation and macular edema.Conclusion. The use of minimally invasive phacoemulsification technique and intravitreal administration of Ozurdex implant in uveitisassociated cataract patients provides an uncomplicated postoperative period.
