Combined use of high-reflective index vitrectomy meniscus contact lens and a noncontact wide-angle viewing system in vitreous surgery
Inouye Eye Hospital, Chiyoda-ku, Tokyo, Japan
Background: The aim of this study was to assess the combined use of a high-reflective index vitrectomy (HHV) meniscus contact lens and a noncontact wide-angle viewing system in vitreous surgery.
Methods: Twenty-three gauge vitrectomy was performed with combined use of a HHV meniscus contact lens and a noncontact wide-angle viewing system. When delicate manipulation of the retina such as internal limiting membrane peeling was performed, only the HHV meniscus lens was used.
Results: Advantages of this combination procedure include the ability to observe the peripheral fundus image, easy access to the posterior pole without exchange of the contact lens when needed, keeping the corneal surface wet covered by a contact lens, and the good view afforded during fluid–air exchange.
Conclusion: Combined use of a HHV meniscus contact lens and a noncontact wide-angle viewing system is useful for vitreous surgery. It has the advantages of both contact and noncontact wide-angle viewing systems.
