A new lens for observing fundus with a noncontact wide-angle viewing system

Mihori Kita, Yukiko Fujii, Sachiyo Hama Department of Ophthalmology, National Organization Kyoto Medical Center, Kyoto, Japan Abstract: Drying of the cornea during surgery, which causes poor visibility of the fundus, is one of the most serious problems when using a noncontact-type wide-angle viewi...

This study used a newly commercialized lens for observing the fundus with a noncontact wide-angle viewing system. The lens used has a very thin meniscus made of polymethyl methacrylate and a large outer diameter. Following the application of viscoelastic material, the lens can be put on the cornea without using a contact lens fixation ring. The larger diameter and lightweight characteristics of the new lens contributed to the overall stabilization. The smooth surface of this lens was able to achieve an intraoperative view of good quality not only during vitrectomy but also during scleral buckling procedures.
