Proportions were compared on AS-20 and VFQ-25 composite scores and also between successes, partial successes and failures.

^aP≤0.01 significant difference between success and failure

^bP=0.04 significant difference between success and partial success

^cP=0.01 significant difference between partial success and failure

^dP=0.005 significant difference between AS-20 and VFQ-25 composite scores.

AS-20 = Adult Strabismus-20; VFQ-25 = National Eye Institute Visual Function Questionnaire-25
