Posterior-Chamber Phakic Intraocular Lens Implantation in Patients over 40 Years of Age

Figure 2

Postoperative spherical equivalent accuracy (a), attempted-versus-achieved spherical equivalent (b), and scatterplot of preoperative and 1-year postoperative astigmatic vectors (c). Solid line in figure B represents the best-fit line (regression equation and R value was included) and dotted lines ±1.00D. In the third figure, the more central location of postoperative data around 0 represents a reduction in astigmatism after lens implantation (J0 = Jackson cross-cylinder, axes at 180° and 90°; J45 = Jackson cross-cylinder, axes at 45° and 135°).
