Purpose: To identify and describe adverse events (AEs) observed with real-world use of the following 3 vitrectomy platforms: Constellation (Alcon), Enhancing Visual Acuity (EVA, Dutch Ophthalmic Research Center), and Stellaris (Bausch + Lomb). Methods: All reports submitted to the US Food and Drug Administration's Manufacturer and User Facility Device Experience (MAUDE) database between January 2010 and November 2021 that were associated with the 3 vitrectomy platforms were analyzed. Each report was reviewed for AEs or consequences and the type of complication noted. Duplicates and reports with an inadequate narrative to categorize the event were excluded. A descriptive analysis was performed for the prevalence of device-specific issues within each platform. Results: The analysis included 2534 reports (1738 Constellation, 117 EVA, 679 Stellaris). Overall, the most commonly reported complications involved the vitrectomy probe (n = 957 [37.8%]) and the central processing unit (n = 368 [14.5%]). Differences in the distribution of AEs among the platforms were noted, with vitrectomy probe issues being the most reported events for the Constellation and Stellaris and infusion issues for the EVA. Infusion issues most frequently led to reports of patient harm with the Constellation (31/1738 [1.8%]) and EVA (7/116 [6.0%]), while issues with the vitrectomy probe were reported with the Stellaris (11/679 [1.6%]). Conclusions: An analysis of real-world data in the MAUDE database highlighted the spectrum of device-specific AEs of greatest relevance to surgical practice. Familiarity with potential device complications will help minimize harm to patients., Competing Interests: Dr. Kovas: Intergalactic Therapeutics (consultant).

Purpose: To report a technique to remove a dislocated ganciclovir implant in the vitreous cavity., Methods: Retrospective case series. Two patients with dislocated ganciclovir implants in the vitreous cavity., Results: A 6-mm pars plana incision was made; the soft tip was used to elevate the implant behind the intraocular lens and then 0.12-mm forceps were used to externalize the implant. The implant was successfully removed in both patients., Conclusion: Removal of a dislocated ganciclovir implant with its encasing strut can be effectively retrieved using a bimanual approach., (Copyright © 2023 The Author(s).
