Purpose: To compare the surgical results in cases of primary rhegmatogenous retinal detachments between standard scleral buckling (SSB) and scleral buckling with chandelier illumination (SBC) and to analyse the differences in SBC surgical results between an experienced ophthalmologist and inexperienced ophthalmologists.

Methods: Consecutive surgical case series of 155 eyes that underwent scleral buckling were retrospectively reviewed and divided into four groups: SSB performed by an experienced ophthalmologist (n = 54), SBC performed by an experienced ophthalmologist (n = 52), SBC performed by inexperienced ophthalmologists (n = 40) and SSB performed by inexperienced ophthalmologists (n = 9). Then, these four groups were compared.
