    Dear Sir

    We read with interest Babu’s report on ‘Utility of digitally assisted vitreoretinal surgery systems (DAVS) for high volume vitreoretinal surgery centres: a pilot study’.1 As the first unit in the United Kingdom to purchase and use the NGENUITY 3D Visualization System (Alcon Laboratories, Fort Worth USA), we would like to share our experience. We assessed DAVS against analogue microscope (AM), from the Consultant surgeons’, trainees and the scrub nurses’ perspective. In our group there was a rapid adaption to the altered colours, head position and stereo vision offered by the DAVS for macular disease, with slower uptake for complex retinal detachments and trauma. In particular, we found the view and quality of image colour in macular cases to be sharp, even at high magnification, making for easier and safer membrane peels. DAVS provided a tangibly improved image quality and ease of description and teaching never previously experience by everyone present in theatre. Surgical trainees particularly benefited from better anatomical and a 3D view of the vitreoretinal pathology. Anecdotally, we tend to agree with Babu et al’s findings that the limitations lie in complex anterior segment cases, particularly with a poor red reflex, where we found the view of the posterior capsule to be compromised compared to the AM. Also, the presence of a sizeable disparity in contrast between immediately adjacent structures in the posterior segment (e.g. colobomas, asteroid hyal...
