An alternative gonioscopy and fundus contact lens protocol.

The clinical procedures for gonioscopy and fundus contact lens examination traditionally have required the use of a topical anesthetic and an interface solution. I have replaced the topical anesthetic and interface solution with a disposable contact lens. The alternative protocol was performed on 18 volunteers, none of whom showed any significant adverse effects of the procedure. The pre- and post-slit lamp microscopic results are discussed in addition to the advantages and potential pitfalls of the new protocol.
