Brief summary
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
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.
