Subjective and Objective Refraction in Pseudophakic Patients

NCT04319497 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 100

Last updated 2020-03-24

No results posted yet for this study

Summary

Targeting of post-cataract refraction depends mainly on the prediction of the post-operative lens position, but also on the post-operative refraction itself. Hence, aim of this study is to evaluate the agreement and variability of subjective refraction performed by two independent examiners, autorefraction, and wavefront aberrometry in pseudophakic patients after uneventful cataract surgery.
