Ray tracing for intraocular lens calculation - PubMed

WebPurpose: To compare corneal astigmatism derived from total corneal refractive power (CA TCRP), a ray-tracing method, with that derived from simulated keratometry (CA SimK), an anterior surface-based method, in candidates for toric intraocular lens (IOL) implantation. Design: Reliability analysis. Methods: In 1 eye of 200 consecutive patients (mean age 71 ± … WebTherefore, ray tracing is no more advantageous than third-generation IOL formulas to predict the accuracy of postoperative IOL position (Figure 2).
