Emmetropia deviation in autorefraction compared to subjective refraction result in patients after corneal refractive surgery.

ABSTRACT:

Background

Automatic refraction is commonly applied as a substitute for subjective refraction to evaluate residue refractive error after corneal refractive surgery. Previous research pooled the data from patients of different subgroups to calculate the difference between automatic and subjective refraction, which lacks clinical implications. The present research aims to investigate the difference between subjective and automatic refraction by subgroups in a large population to guide the proper use of autorefraction after corneal refractive surgery.

Methods

Patients between 18 and 50 years who underwent corneal refractive surgery to correct myopia and astigmatism, including photorefractive keratectomy (PRK), femtosecond laser-assisted in situ keratomileusis (FS-LASIK), or sma
