Eligibility
Inclusion criteria
Inclusion criteria: 1. Patients aged 35-45 who underwent SMILE surgery in both eyes, with the dominant eye selected as the primary study eye; 2. Both eyes meet the SMILE surgery criteria before surgery; 3. Preoperative accommodation amplitude of 3.5D-7D; 4. Preoperative astigmatism = 0.8; 6. Experiencing visual fatigue 1 week after surgery. Diagnostic criteria for visual fatigue: (1) blurred vision, inability to maintain prolonged focus, difficulty in focusing, inaccurate focusing; (2) ocular discomfort such as eye fatigue, eye soreness, eye pain, pulling sensation in the eyeball, photophobia, tearing, foreign body sensation, or dryness; (3) accompanied by headache, lack of concentration, easy fatigue, or memory decline. Diagnosis can be made if 2 of (1), (2), and (3) are present; 7. Accommodative sensitivity <11 cpm/min in one eye, <8 cpm/min in both eyes one week after surgery; 8. Agree to perform 15 minutes of VR training/reverse photography training at home daily during the study period, notify the researchers if unable to comply, and are able to accept and complete follow-up examinations on time; 9. I understand and agree to participate in this clinical trial and have signed the informed consent form.
Exclusion criteria
Exclusion criteria: 1.Have absolute contraindications for SMILE surgery. 2. Have SMILE surgery failure/abnormalities. 3. Have received flipper/other visual function training within the past half year. 4. Have used anti-fatigue drugs within one month prior to enrollment. 5. Have active eye diseases. 6. Have severe dry eyes. 7. Have eye diseases such as glaucoma, strabismus, amblyopia, and nystagmus. 8. Have a history of eye trauma or other eye surgeries. 9.
