Refractive Outcomes and Ocular Biometry of Two Swept-Source Optical Coherence Tomography-Based Biometers With Segmental or Equivalent Refractive Indices (ORION)

Sponsor: Walailak University

Summary

Cataract surgery represents a common surgical intervention, encompassing the extraction of the opaque natural crystalline lens, followed by the substitution with an artificial intraocular lens (IOL). To ascertain an IOL possessing optimal power, antecedent to the surgery, preoperative evaluations are conducted through the utilization of a biometric devices. Diverse categories of these instruments are accessible, each harnessing distinct optical methodologies or mathematical algorithms to ascertain the most fitting IOL power. The principal objective of this study was to evaluate the ocular biometry and the predictive precision outcome of a biometer that uses standard keratometry to the prediction accuracy of another biometer that uses Total Keratometry.
