Purpose To describe the use of commercial DSLR for vitreoretinal surgery recording and compare it to standard 3-chip CCD camera Methods: Simultaneous recording was done using Sony A7s2 camera and Sony high definition 3-chip camera attached to each side of the microscope. The videos recorded from both the camera systems were edited and sequences of similar time frames were selected.The videos of each sequence were evaluated for color, contrast and overall quality.Results: The mean scores of the two cameras were comparable for each other on all parameters assessed in the different videos except of color and contrast in posterior pole view and color on wide-angle view, which were rated significantly higher in DSLR camera. Conclusion: Commercial DSLRs are an affordable low cost alternative for vitreoretinal surgery recording and may be used for documentation and teaching.
