We here describe the use of one such smartphone, (HTC Incredible S) for acquiring High Definition video of ocular surgery through standard operating microscope with assistant observer scope. Further we will be discussing only the smartphones with Android operating system and camera supporting at least 8 megapixel camera and full HD (1280*720 pixels) video recording at 30 frames per second.

4 The camera interface of these smartphones has rich features and has numerous advantages over the conventional imaging system used in ophthalmology, both for stills and videos. Recently the availability of smartphones with processing capabilities comparable to computers and plethora of sensors has made their application in medical science increasingly popular. Later on this is edited using computer to produce a video of desired quality, with narration and captions. These cameras produce analog signal which is then transferred to a recording device (VCR, DVD recorder, Hard Disk Recorder, Commuter video Capture Card etc.). Conventionally the video and still imaging of surgical videos has been done using CCD (Charged Couple Device) camera attached to a beam splitter and C-mount. Videos have important role in skill transfer and training, 1, 2 demonstration of new procedures, 3 and as material of clinical evidence. Video recording and still photography is an essential component of documenting surgical and clinical details. We have described the arrangement used to mount the smartphone to microscope and discussed the advantages and limitations of this arrangement when compared to a conventional capturing and recording system used with the operating microscope. We here describe the use of an Android smartphone, (HTC Incredible S) for capturing High Definition (HD) video of ocular surgery through the assistant observer scope of an operating microscope. Additionally videos have important role in skill transfer, demonstration of new procedures, and as material of clinical evidence. Video recording and still photography is an essential component for documenting surgical and clinical details.
