Nomogram for Astigmatism Correction of KLEx

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This interventional study investigates the use of a nomogram to guide astigmatism correction. Eligible participants are adults 18 years and older with specific refractive errors and healthy corneal measurements. Participants will be followed for 3 months with manifest refraction and visual acuity assessments to compare nomogram-guided treatment with non-nomogram approaches. The study aims to see if the nomogram can lead to acceptable, if not improved, treatment results. Additional details on methodology and outcomes are not provided in the available summary.
