Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study evaluates the various ocular parameters which are necessary for ocular biometry and the calculated IOL powers using both dual Schiempflug analyzer and optical low-coherence refelctometry.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The measured keratometry, axial length, anterior chamber depth, lens thickness, white-to-white corneal diameter, and calculated IOL powers using various formulas including Hoffer Q, Holladay I, SRK II and SRK T measured by dual Schiempflug analyzer and optical low-coherence refelctometry will be compared.
