Early and Late Complications after Cataract Surgery in Patients with Uveitis

Abstract

Background and Objectives: Uveitis, a prevalent eye disorder characterized by inflammatory processes, often leads to cataract formation and significant visual impairment. This study aimed to evaluate preoperative conditions and postoperative outcomes following cataract surgery in uveitis patients. Materials and Methods: A retrospective study was conducted at the University Hospital Center Rebro Zagreb, Croatia, involving uveitis patients who underwent cataract surgery between 2013 and 2022. Eligible patients had uveitic cataracts affecting visual acuity or posterior segment visualization in a "quiet eye" and were disease-inactive for at least three months. Patients with certain preexisting ocular conditions were excluded. Data collected included patient demographics, uveitis type, preoperative therapy, preexisting lesions, and postoperative outcomes such as visual acuity, intraocular pressure, central macular thickness, and complications. Statistical analysis was performed to identify risk factors associated with complications. Results: The study included 105 patients. After cataract surgery, there was a significant improvement in visual acuity at various time points, with 90% of eyes showing improvement. Intraocular pressure decreased over time. Central macular thickness increased at three months post-surgery but remained stable thereafter. Early and late complications were observed in 52.4% and 63.8% of eyes, respectively. The most common complications were posterior capsular opacification, macular edema, and epiretinal membrane. Factors associated with complications varied between early and late stages but included age, age at onset of uveitis, and uveitis type. Conclusion: Cataract surgery in uveitis patients presents challenges but can lead to significant visual improvement. This study highlights the importance of careful patient selection, preoperative and postoperative inflammation management, and precise surgical techniques. Although complications were common, they were manageable, and most patients experienced improved vision, emphasizing the benefits of cataract surgery in this population. However, future investigations should address the study's limitations and further refine perioperative strategies.
