Refractive Outcomes Utilizing Two SS-OCT Biometers for IOL Power Calculations
The Eye institute of Utah
Summary
The purpose of this study is to evaluate and compare the potential refractive outcomes using the Argos 1.5 biometer in the surgical planning for cataract extraction to that obtained from IOLMaster 700. Both devices are used as standard of care in surgical planning optimization for patients undergoing cataract surgery.
Description
Cataract surgery is one of the most performed surgical procedures globally. The goal of the cataract surgeon is to implant an intraocular lens (IOL) with an appropriate IOL power to compensate for the refractive error and leave the patient emmetropic. The accurate measurement of ocular parameters is therefore critical for the effective calculation of IOL power, which directly impacts postoperative visual outcomes. However, accurate IOL power determination is influenced by several factors, including the measurement techniques employed and the specific biometers used in the process. Optical bio…
