PURPOSE: To evaluate the changes in axial length (AL) and corneal astigmatism induced by scleral imbrication on all quadrants in pig eyes. STUDY DESIGN: Experimental study METHODS: We produced scleral imbrications either on all quadrants or on 2 consecutive quadrants of 5 enucleated pig eyes. Scleral imbrications 8 mm wide were made at 8 mm from the limbus on each quadrant. We determined the AL using an electronic caliper and the corneal astigmatism using a keratometer before and after the 2 types of scleral imbrications and compared the changes in ocular AL and corneal astigmatism induced by the 2 surgical procedures. RESULTS: The AL reduction after the scleral imbrication on all quadrants (3.96 ± 0.56 mm) was larger than that on 2 quadrants (2.39 ± 0.41 mm) (P = .001). The change in corneal astigmatism induced by imbrication on all quadrants (2.98 ± 1.96 D) was less than that on 2 quadrants (5.95 ± 2.04 D) (P < .029). CONCLUSIONS: Scleral imbrication on all quadrants induced a shorter AL and less corneal astigmatism than did a standard scleral imbrication on 2 quadrants. Therefore, the former could be a more effective operation for retinal disorders associated with high myopia, including macular hole retinal detachment and myopic foveoschisis.
