PURPOSE: To report a new wide-angle viewing contact lens for vitrectomy. DESIGN: New surgical instrument. METHODS: The new wide-angle viewing lens is made of glass and polymethyl methacrylate without a plastic rim. The diameter is reduced to 16.2 mm. In addition to a smaller diameter than the currently available lens, the new lens is partially cut to reduce the lens diameter. RESULTS: A smaller diameter makes it possible to eliminate contact between surgical instruments and the wide-angle lens. Instruments can be inserted through sclerotomies without removing the wide-angle lens. The optical properties are otherwise identical to the standard wide-angle lens. CONCLUSION: The new wide-angle viewing lens may be easier to use in vitreous surgery.
PURPOSE: To evaluate the feasibility of illuminating the fundus by combining a wide-angle-viewing contact lens and slit lamp attached to a surgical microscope during retinal reattachment surgery and vitrectomy. DESIGN: An interventional study. METHODS: We combined slit-lamp illumination and a wide-angle-viewing contact lens to visualize the fundus during retinal reattachment surgery and vitrectomy. RESULTS: We clearly observed the fundus using this combination approach during conventional retinal reattachment surgery, which we completed without using an indirect ophthalmoscope. With slit-lamp illumination, the wide-angle-viewing contact lens provided a wider area of illumination than a planoconcave contact lens during vitrectomy in addition to an area of illumination as wide as that obtained using a light pipe. CONCLUSIONS: Combining slit-lamp illumination and a wide-angle-viewing contact lens seems to provide a useful alternative method for viewing the fundus during vitreoretinal surgery.
Three instruments developed by David M. Maurice, i.e., pachometer, fluorophotometer and specular microscope, helped clinicians develop improved clinical practice. It covered wide areas, such as contact lens practice, cataract surgery, medical therapy of intraocular inflammation and glaucoma.
