Summary

The purpose of this study is to evaluate current available assessments (automated vs. manual) with which manifest refraction data and biometric variables are obtained to understand if data from an automated refractor can be utilized to optimize the A-constant as well as manual subjective refraction (ie, to a clinically insignificant difference). The A-constant is the calculated number that helps the surgeon determine which IOL should be implanted in the eye during cataract surgery.

Conditions

  • Cataract
