If the eye examination value is normal but the effect of wearing keratoplasty lenses is not good, it may be related to poor daily eye habits, insufficient wearing time, irregular corneal shape and other factors. 1. Poor daily eye habits: Wearing keratoplasty lenses can have the effect of controlling myopia growth. Although the eyes are normal during the examination and fitting, if the patient uses too much near eye in daily life, especially electronic products, myopia can grow faster, and the effect of controlling myopia growth by wearing keratoplasty lenses will therefore become worse. 2. Insufficient wearing time: Keratoplasty lenses need to be worn for 8~10 hours during sleep time at night every day. Although the patient’s eyes are normal, some of the children cannot guarantee 8 hours of sleep time at night because of the heavy study load, and the effect of Keratoplasty lenses will be unsatisfactory after wearing them. 3. Irregular corneal shape: everyone’s corneal shape is different, some people have regular corneal shape, some people have irregular corneal shape. Usually, the irregular corneal shape is not good enough to fit with regular design of keratoplasty lenses, and it is necessary to change to cycloplegic design of keratoplasty lenses. It is recommended that patients who experience ocular discomfort after wearing keratoplasty lenses should seek prompt medical attention to evaluate their condition and follow the doctor’s instructions for treatment.
