Quantification of the psychosocial effects of manifest strabismus has been made possible by the introduction of the Adult Strabismus 20 (AS-20) questionnaire. We investigated the effects of strabismus surgery and patient demographics on the pre- and postoperative AS-20 scores. ⋯ Strabismus surgery gives a highly significant improvement in quality-of-life scores. Females gain more benefit from surgery and there is a greater improvement in the score with larger changes in deviation size. The smaller the postoperative angle, the larger the final AS-20 score.
