Stereoacuity was compared preoperatively to six weeks postoperative after cataract extraction and intraocular lens (IOL) implant. The authors evaluated the association of postoperative stereoacuity with visual acuity, age and duration of preoperative symptoms. This prospective study recruited 142 patients: 92 
male and 50 female. Stereoacuity was measured in 30% preoperatively and 99% postoperatively, which was significant at p=0.0001. Increase in age was associated with reduced stereoacuity. There was no significant correlation of stereoacuity and duration of symptoms. Postoperative stereoacuity was correlated with postoperative visual acuity in the better eye. No correlation was found for stereoacuity and inter-ocular visual acuity difference.
