PURPOSE: To investigate and compare the anatomic and functional outcomes of chandelier-assisted scleral buckling (CASB) surgery using contact versus non-contact lens-based wide-angle viewing systems (WAVSs) in rhegmatogenous retinal detachment (RRD) patients. METHODS: This was a retrospective, multicenter study evaluating the anatomic (reattachment rate) and visual acuity (VA) outcomes at 6 months post-CASB for primary RRD. RESULTS: Forty-seven RRD patients underwent CASB with a non-contact WAVS (Group C1) and 90 with a contact lens WAVS (Group C2). Preoperative parameters including myopia, macula-off RRD, posterior vitreous detachment, number of retinal breaks, and retinal dialysis as the etiology of RRD did not differ significantly between the two groups. The outcomes of retinal attachment (85.11% of C1 patients and 76.67% of C2 patients, P = 0.34) and final visual outcome (VA ≥6/12: C1 = 61.7%; C2 = 46.67%, P = 0.13) were also comparable. Furthermore, no significant difference in postoperative complications such as cataracts, glaucoma, infection, buckle exposure, and buckle failure was observed. Finally, both groups were comparable in terms of re-detachment rates (10.64% in C1 and 23.33% in C2, P = 0.11). CONCLUSION: The two WAVS approaches used in CASB surgery have comparable surgical and functional outcomes and postoperative complications. The operating surgeon can freely choose between these viewing platforms during the contemporary scleral bucking (SB) surgery without impacting the outcome.
