Patients with 400 degree myopia can wear OK lenses, i.e. keratoplasty lenses, for myopia correction. Generally, patients’ visual acuity can reach 1.0 in about 2 weeks, but the specific effect is related to the patient’s condition.
Patients wear keratoplasty lenses at night, which presses the cornea to deform and change the curvature of the cornea, thus correcting the refractive state of the patient and improving the visual acuity. However, the correction process is gradual, not the second day after wearing the lens patients can reach 1.0 visual acuity, generally 400 degrees myopia patients need to wear the lens for about 2 weeks to be able to improve to 1.0, but the specific time is related to the patient’s condition.
Keratoplasty is a commonly used ophthalmic correction and treatment for myopia, generally suitable for myopia below 500 degrees. After wearing Keratoplasty lenses, patients need to develop good hygiene habits to avoid eye infections.
It is recommended that patients who experience eye discomfort after wearing keratoplasty lenses should consult a hospital in time to assess their condition and follow the doctor’s instructions for treatment.
