Summary

To evaluate the impact of refractive errors on the central corneal thickness obtained by Pentacam and intraocular lenses (IOL) master in eyes with different refractive errors.

Detailed description

Central corneal thickness (CCT) is a key indicator of corneal health status and helps to assess corneal diseases. The normal corneal thickness is about 540 μm and mainly consists of the stroma, which is estimated at 450 μm in the center. The stroma provides vital structural integrity and plays a key role in helping maintain transparency. It has been reported, however, that CCT follows a diurnal pattern being 10 μm thicker in the morning due to reduced evaporation of water from underneath the closed eyelids
