Comparison of complications and visual outcomes of combined phacovitrectomy vs stand-alone phacoemulsification: multicenter database study.

PURPOSE: To compare the rates of intraoperative complications, cystoid macular edema (CME), and visual outcomes in eyes that underwent combined phacovitrectomy (Phaco-PPV) with those with stand-alone phacoemulsification. SETTING: A multicenter database study across 8 ophthalmology departments in the United Kingdom. DESIGN: Retrospective, nonrandomized, multicenter comparative study. METHODS: We extracted data for patients who underwent Phaco-PPV and stand-alone phacoemulsification from January 2000 through May 2015. The primary study outcomes were the rates of intraoperative complications and CME postoperatively. RESULTS: The study included 2222 eyes in the combined Phaco-PPV group and 112 689 in the stand-alone phacoemulsification group. The combined Phaco-PPV group had a higher incidence of posterior capsule rupture (2.7% vs 1.7%), dropped lens fragments (0.5% vs 0.2%), suprachoroidal hemorrhage (0.4% vs 0.1%), and CME (3.6 vs 1.1%) ( P < .001). The mean preoperative visual acuity (VA) was lower in the combined Phaco-PPV group, with a mean VA of 0.98 vs 0.68 logMAR (Snellen ∼20/200 vs 20/100) in the stand-alone phacoemulsification group ( P < .001). VA at 24 weeks was lower in the combined Phaco-PPV group (mean VA 0.67 vs 0.22 logMAR (Snellen ∼20/100 vs 20/32), P < .001). CONCLUSIONS: Combined Phaco-PPV had higher rates of intraoperative complications and CME, along with a lower postoperative VA, when compared with stand-alone phacoemulsification surgery.

The Use of Ologen Implant in Childhood Glaucoma Surgeries: A Review.

PURPOSE: This study assesses the effectiveness and safety of using Ologen implants (Aeon Astron Europe BV, Leiden, The Netherlands) as an adjunctive therapy in childhood glaucoma surgeries. METHODS: We systematically reviewed the existing literature across various electronic databases to examine the effectiveness and safety of Ologen implants in childhood glaucoma surgeries. RESULTS: Our analysis encompassed 14 studies on the use of Ologen implants in childhood glaucoma. Among these, seven were prospective, five were retrospective, and two did not specify their study design. Success rates varied depending on the type of surgery and the included childhood glaucoma subtype. The success rates for Ologen implants-augmented surgeries were as follows: 33.3-70% for trabeculectomy, 50-81% for combined trabeculotomy-trabeculectomy procedure, 33%-87% for glaucoma drainage device, and 60% in deep sclerectomy. CONCLUSION: Ologen implant has a potential role in mitigating postoperative fibrosis and enhancing success rates in various childhood glaucoma surgeries. However, the existing literature is limited. Future comparative prospective studies with larger cohorts are needed.
