This study evaluates corneal epithelial thickness using anterior segment optical coherence tomography (AS-OCT) in patients with refractive errors. It aims to assess the relationship between epithelial thickness patterns and different types of refractive errors.

* Patients diagnosed with myopia or hyperopia by refraction
* Clear cornea with no evidence of corneal pathology
* Ability to undergo reliable anterior segment imaging
Exclusion Criteria:
* Inability to fixate or follow instructions

Primary outcome measure(s)
Measurement of corneal epithelial thickness using AS-OCT — At baseline during a single study visit when participants undergo AS-OCT examination. Corneal epithelial thickness will be measured using anterior segment optical coherence tomography (AS-OCT). Measurements will include central and regional epithelial thickness values in microns in patients with different refractive errors.
