Tarsal switch procedure for the surgical rehabilitation of the eyelid and socket deficiencies of the anophthalmic socket

Abstract

Purpose: To describe a tarsal transfer procedure, which we have named the "tarsal switch," to correct the eyelid malpositions and camouflage the socket defects of acquired anophthalmos.

Methods: The technique consists of an upper eyelid tarsectomy, with transfer of the autologous tarsoconjunctival graft to the posterior lamella of the lower eyelid.

Results: The operation was performed in 21 anophthalmic patients. In 16 patients with eyelid malpositions, excellent results (within 1 mm of the fellow eye) were attained in 100% of the patients with ptosis, and in 88% of patients with lower eyelid retraction. In the remaining 5 patients, orbital volume loss with secondary implant migration, inferior prosthetic displacement and eyelid asymmetry predominated. In these patients the anophthalmic orbital defects and eyelid asymmetry were masked well. Patient satisfaction was high and complications were few during an average follow-up interval of 16 months.

Conclusion: The tarsal switch procedure is useful in managing the eyelid malpositions and masking the orbital deficiencies of the anophthalmic socket.
