Orthokeratology is a nearsighted control program where a child sleeps with a pair of breathable contact lenses that gently reshapes their cornea. During daytime, contact lenses are removed and the child will be able to see without their glasses. A nearsighted patient would have light rays focused in front of their retina: When corrected with regular eyeglasses or contact lenses, the central rays of light will now be focused on the retina, however the rays of light on the side will focus behind the retina. This would cause the brain to tell the eye to elongate so that they can put the focus back to the retina. This will just begin a cycle again wherein the central rays of light are not focused correctly on the retina. During orthokeratology, the new shape of the cornea alters how light rays enter the eye, thus preventing the elongation of the eyeball. Orthokeratology does not remove or lessen the grade or prescription, but just controls it from getting higher and higher ea
There is a myopia (nearsightedness) epidemic happening in so many countries all over the world. Patients we see with myopia in the clinic are becoming younger and younger. Singapore, Taiwan, Hong Kong have seen the most childhood myopia in their statistics, and Philippines has been following their footsteps. Clinical trials are being done by top scientists in order to find means in controlling and preventing myopia. Currently, myopia control can be achieved with specially designed contact lenses and ophthalmic lenses. But what is also important is to control some environmental factors that can cause the progression of myopia. Kids will say that you want to blame your parents for giving you myopia, but studies show that 78.4% in 15- year old children are myopic, compared with only 19.8% in parents… this means environment really plays a big role. Indeed times have changed. Some kids do not even know how to play dolls or cars or robots… And whether you want to admit it or not, some pare
