They also had a postoperative best\u2010corrected visual acuity of better than 20\/40 in both eyes. All patients underwent an ophthalmologic examination including best spectacle\u2010corrected visual acuity and binocular alignment. Stereoacuity was evaluated using the Titmus Stereotest and a stereoacuity of 100 sec of arc or better was designated as \u201cgood\u201d stereoacuity. Binocularity was determined using the polarized 4\u2010dot test at distance and at near and the reporting of 4 dots were used to establish fusional ability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results.<\/jats:title>\n                    <jats:p>Four of the nine patients (44.4%) showed the highest stereoacuity of 40 sec of arc and another four patients (44.4%) showed a stereoacuity of 50 or 60 sec of arc.
