Partially accommodative esotropia is an esotropia that is not fully corrected by wearing full cycloplegic refraction. The aim of surgery for partially accommodative esotropia has been directed only at correcting the residual angle that was not corrected with glasses, i.e., the non-accommodative element. Three methods have been proposed for determination of the surgical target angle: standard surgery formula, augmented surgery formula and prism adaptation. Both the standard recession and the enhanced recessions led to high undercorrection rates. On the other hand, the augmented recession was known for its tendency to overcorrection. This was a prospective randomized interventional comparative study on patients with partially accommodative esotropia who have normal accommodative convergence to accommodation ratio Fifty-three patients with partially accommodative esotropia with normal were enrolled in this study. This study aimed to compare bilateral medial rectus recession, based on the distance angle with correction which is the smallest angle, reinforced by posterior scleral fixation to bilateral medial rectus augmented recession based an average between the distance angle with glasses and the near angle without glasses. The overall success in the Faden group was 64.29%; 35.71% were orthotropic with and without glasses and 28.57% were orthotropic with glasses but undercorrected without glasses. The overcorrection rate was 32.14% and the undercorrection rate 3.57%
