Authors retrospectively analyzed 22 cases of inferior oblique overaction, which were treated by means of infetior tlblique recession from May 1983 to June 1985. We compared preoperative and postoperative hyperdeviation in the primary position and adduction, and calculated the amount of corrected hyperdeviations in the prirrtary position and adduction pet millimeter of inferior oblique recession. The results were as follows: 1. The overall success rate was 84.4 % in primary inferior oblique overaction. 2. The amounts of correction in the primary position per millimeter of inferior oblique recession were 0.69 prism diopter. 3. The amounts of correction in adduction per millimeter of inferior oblique recession were 1.94 prism diopter. 4. Decrement amounts in adduction compared to in the primary position were 1.59 prism diopter per millimeter of inferior oblique recession.

Although most available IOL power calculation formulas perform accurately for eyes of average axial length, they have been shown to be inaccurate for eyes that have unusually short and long axial length. To compare the prediction accuracy of new Hoffer Q with SRK-II formula, we reviewed, retrospectively, a series of 225 ECCE with PCL implantation cases, including 106 Hoffer Q group and 119 SRK-II group, each of which was further divided into subgroups based on axial length. The Hoffer Q formula overestimated the refraction and resulted in more myopic shift and was less accurate than SRK-II in all length eyes, except short length eyes. In short length eyes, both formulas had similar mean error and mean absolute error but Hoffer Q formula was more accurate than the SRK-II in +/- 0.5D prediction proportion.
