Wide-angle viewing systems are used regularly during vitrectomy. Noncontact wide-angle viewing systems are popular, but they cause the corneal surface to dry, often resulting in a blurred fundus view. With such systems, surgical assistants must periodically irrigate to prevent drying, but the added water droplets on the corneal surface can further reduce the quality of the field view. Dr. Masahito Ohji discusses the combination of a wide-angle viewing system with a contact lens to provide a wider, more reliable fundus view without the need for surgical assistance.
