Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

1. Study the changes in subjective visual quality, contrast sensitivity, and total ocular aberrations of patients with low-to-moderate myopia after SMILE and LASEK surgeries at different age groups;
2. Evaluate the effects of SMILE and LASEK surgeries on the visual conduction pathway PVEP in patients with refractive errors of different age groups;
3. Clarify the correlations between subjective and objective visual quality after SMILE and LASEK surgeries in patients with refractive errors of different age groups and PVEP.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients with refractive errors who were scheduled to undergo SMILE surgery and LASEK surgery were selected. The preoperative equivalent spherical diopter (SE) of the affected eye was less than -6D. The surgical plan was based on voluntary principle and was divided into the SMILE group and the LASEK group. Each surgical group was further divided according to age into groups of ≤ 20 years old, 21-30 years old, 31-40 years old, and ≥ 41 years old. Each group consisted of 35 patients. There were no significant differences in gender, equivalent spherical diopter (SE), optical zone, and preoperative best corrected visual acuity among the groups.

Exclusion Criteria

* The nearsightedness has increased by more than 1D in the past two years. Severe dry eye syndrome, keratoconus, glaucoma, history of eye surgery, severe systemic connective tissue or autoimmune diseases
