To apply a new television system, which displays highly sensitive, high-quality 3-dimensional (3-D) images, in performing experimental ophthalmic surgeries.
By combining a high-gain avalanche rushing–amorphous photoconductor (HARP) camera, recently developed in Japan, which has 600 times greater sensitivity than conventional television cameras, and a single-camera, 3-D high-definition television system, which displays high-quality 3-D images, we performed cataract/intraocular lens surgeries and pars plana vitrectomies under various illumination intensities in pig cadaver eyes.
Cataract/intraocular lens surgeries were performed using 7.3% the intensity of ordinary surgical microscopic illumination; vitrectomies were performed using 30.2% the intensity of an ordinary endoillumination probe with the HARP camera and by observing the stereoscopic display of the single-camera 3-D high-definition television system. Images identical to those observed by the surgeon were displayed on the stereoscopic display monitor.
The system not only allowed surgeries to be performed under lower intensities of operating light but also provided real-time, highly sensitive 3-D images identical to those observed by the surgeon; thus, the device may be effectively used for education, team surgery, and telesurgery.
