Early and Late Complications after Cataract Surgery in Patients with Uveitis.

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 pre-existing ocular conditions were excluded. The 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: This study included 105 patients. The most common uveitis types were idiopathic uveitis, HLA-B27-associated uveitis, and JIA uveitis. 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 (53.3%), macular edema (26.6%), and epiretinal membrane formation (9.52%). The factors associated with complications varied between early and late stages but included age, age at the onset of uveitis, and the uveitis type. Conclusions: In patients with quiescent uveitis undergoing cataract surgery, significant visual improvement was achieved. This study highlights the importance of careful patient selection, preoperative and postoperative inflammation management, and precise surgical techniques. Although complications were common, the risk of capsular opacification, macular edema, and epiretinal membrane formation after surgery increased. However, future investigations should address this study's limitations and further refine perioperative strategies.

EVALUATION OF VISION-RELATED QUALITY OF LIFE IN PATIENTS AFTER VITRECTOMY FOLLOWING IDIOPATHIC EPIRETINAL MEMBRANE.

PURPOSE: To evaluate the impact of different intraocular tamponades on the vision-related quality of life (VRQOL) after idiopathic epiretinal membrane (IEM) surgery with epiretinal membrane peeling. METHODS: We prospectively enrolled 50 patients diagnosed with IEM who underwent pars plana vitrectomy. Patients were consecutively assigned to either the air tamponade (air) group (25 patients) or the balanced salt solution (BSS) tamponade group (25 patients). The following data were collected before and after surgery and compared between the two groups: VRQOL, best-corrected visual acuity, intraocular pressure, metamorphopsia, contrast sensitivity, and central macular thickness. RESULTS: Pars plana vitrectomy was performed in 50 eyes. At baseline, there were no significant differences between the two groups. At 6 months postoperatively, VRQOL ( P < 0.001), best-corrected visual acuity ( P < 0.001), central macular thickness ( P < 0.001), contrast sensitivity ( P < 0.001), and metamorphopsia ( P < 0.001) improved significantly in comparison with baseline, without significant differences between the air tamponade and BSS groups. CONCLUSION: Removing IEM significantly improved visual function and VRQOL. Despite improvements, this study showed no difference postoperatively whether air or BSS tamponade was used during surgery. As a result, air tamponade may not be a mandatory treatment for IEM surgery and provides no additional advantage compared with BSS tamponade.
