Corneal scratches caused by wearing OK lenses can generally heal on their own if only the corneal epithelium is damaged, but if the corneal damage is deeper, it will be more difficult to recover on its own. OK lenses, also known as keratoplasty lenses, are a common means of correcting myopia. By wearing keratoplasty lenses at night during sleep, the cornea is deformed by pressure and the curvature of the cornea is altered, thus correcting myopia. If you wear keratoplasty lenses for too long or take off and put on the lenses roughly, you may scratch the cornea, resulting in corneal epithelial damage, causing eye congestion, redness, foreign body sensation, tearing and other symptoms, at this time you need to stop wearing keratoplasty lenses, due to the corneal epithelium repair ability is relatively strong, if not continue to damage, it is usually can be self-healing. Patients can also order antibiotic eye drops to prevent infection, such as levofloxacin eye drops, etc., and can also order drugs to promote corneal repair to accelerate its recovery, such as recombinant human epidermal growth factor eye drops, etc.. The medication should be used according to the doctor’s prescription. However, if the OK lens damages a deeper part of the cornea, it may be difficult to heal on its own, and even if it recovers on its own, it may leave a scar. Patients are advised to go to the hospital in time and follow the doctor’s instructions to avoid delays.
