Experimental approach to Z-myotomy. (A) Schematic. Extraocular muscles were clamped at both ends and preloaded to prevent slackness. The specimen was then incised from opposite margins 8 mm apart at predetermined ratios (20%, 40%, 50%, 60%, and 80%) of total width. Reprinted with permission from Shin A, Yoo L, Demer JL.

After clamping the specimen (top), 40% of muscle width was incised from both margins (bottom).
