Abstract: the angular plastic adopts the inverse geometric design, and its inner surface is composed of multiple arc segments, which is designed as flat in the center and steep around. Due to the uneven distribution of tear layer between the lens and the cornea, the radian of the central area of the cornea is reasonably shaped through the hydrodynamic effect after wearing and the pressure of the eyelid on the center of the lens, so as to reduce a certain amount of myopia in a short time.
nowadays, the learning pressure of teenagers is generally large, and more and more children begin to be short-sighted from a very young age. Looking at the children’s degree rising year by year, many parents expressed great concern. Don’t worry, Xiaobian. Here’s a secret weapon to control myopia! What is
corneal shaping lens?
, also known as keratoplasty and OK lens, are high oxygen permeable rigid corneal contact lenses specially designed according to the shape of human cornea.
corneal shaping lenses originated in the United States in the 1960s and have developed for more than 50 years. It is a kind of night glasses. Wearing at night can effectively change the corneal curvature, so that children can enjoy clear naked vision during the day.
secret weapon attribute? The
angle molds adopt inverse geometric design, and their inner surface is composed of multiple arc segments. They are designed to be flat in the center and steep around. Due to the uneven distribution of tear layer between the lens and the cornea, the radian of the central area of the cornea is reasonably shaped through the hydrodynamic effect after wearing and the pressure of the eyelid on the center of the lens, so as to reduce a certain amount of myopia in a short time. The biggest advantage of
angle plastic is to wear it at night and take it during the day to correct myopia in sleep. The effect of controlling the development of myopia is 8 times that of frame glasses.
corneal shaping lens is suitable for who?
corneal plastic lens are different from excimer laser surgery in the treatment of myopia. It is a physical method to control myopia, and the treatment process is non-invasive. However, the premise of fitting is that the patient should have no corner, conjunctival disease and other eye diseases, and no contraindications to wearing contact lenses.
1. Patients who control or slow down the further deepening of myopia in the early stage of myopia formation in children and adolescents;
2. Patients who are unwilling to undergo surgery or cannot wear other glasses during enrollment, recruitment and physical examination;
3. It is an ideal method for athletes, actors and other special occupations not to wear frame glasses and contact lenses;
4. The ideal way not to wear any glasses during the day;
is an ideal method to correct myopia and presbyopia over 5.45 years old;
6. Correction of various refractive errors;
7. It can be used for the correction and treatment of myopia and amblyopia in children;
patients over 8.7 years old unwilling to wear other glasses;
9. Keratoconus patients.
need to be reminded that the correction effect of corneal plastic lens has certain reversibility. Once it is stopped wearing, the corneal shape will gradually return to its original state, and the speed of recovery is related to factors such as the refractive status of the eye and the length of wearing the lens. Therefore, in terms of controlling myopia, it needs a long-term process of wearing glasses.
