Variable-Rate Multispectral Illumination for Retinal Microsurgery: A Critical Review Adaptive Multispectral Illumination for Retinal Microsurgery

Vitreoretinal surgery is undertaken to treat several eye problems involving the retina, macula, and vitreous fluid, and this surgery is considered one of the most difficult to perform. Many eye problems are treated with vitreoretinal surgery including macular degeneration, diabetic retinopathy, and retinal detachment. During vitreoretinal surgery, small implements are inserted into the ocular vitreous cavity through small incisions and are manipulated within through microscopic visualization. There exist many complicating factors in the surgery, including difficult visualization of surgical targets, lack of tactile feedback, phototoxicity, and the requirement for high precision and accuracy. The surgeon experiences limited field and clarity of view, depth perception, and illumination, hindering identification and localization of surgical targets and leading to long operation times.
