Exclusion criteria
Exclusion criteria: (1) One eye meets the inclusion criteria; (2) Those who suffer from systemic diseases resulting in immunocompromise, or those who have an effect on corneal reshaping (e.g., previous diabetes, Down's syndrome, rheumatoid arthritis, psychiatric disorders, etc., or those who have suffered from acute or chronic sinusitis within 1 year, etc.); (3) Those suffering from corneal anomalies, previous corneal surgeries or history of corneal trauma, or corneal hyperalgesia; (4) Those with the following symptoms in the eye: ? Active corneal infections of bacterial, fungal, or viral origin; ? Acute and chronic inflammation of the anterior segment of the eye other than the cornea, such as acute conjunctivitis and blepharitis; ? Any ocular disorder, injury, or structural abnormality that affects the cornea, conjunctiva, or eyelids, e.g., lachrymatorrhoea, glaucoma; ?
