Basic conditions for fitting OK glasses: Medical institutions must have the Practice License of Medical Institutions and the qualification of hospitals above Grade II, and the registered medical subjects include ophthalmology, reception room, examination room, optometry room and wearing room, with good sanitary conditions; Doctors must have the qualification of practicing doctors and the title of ophthalmologist above the intermediate level, and medical institutions must have a series of equipment such as corneal curvature meter and corneal topography meter. Therefore, the fitting of orthokeratology lens needs to be cautious, and if it is fitted by non-professionals in institutions without relevant equipment, the risk is greater. In order to avoid all kinds of complications that are harmful to eye health caused by poor fitting, it is suggested that patients go to regular professional eye institutions to fit orthokeratology lenses, and ensure the safety of the whole treatment process through scientific fitting, regular review and close monitoring by professional ophthalmologists.
