Xiao Ming is a 14-year-old child, at the age of 10 years old began to wear glasses, but every year has been about 100 degrees of degree growth, and astigmatism is getting bigger and bigger, initially 100 degrees, now it is 400 degrees, and how to correct in the optician, are not very clear. So, he came to the hospital to check, and as a result, what happened to his eyes? In fact, it was not a simple increase in his prescription, but the initial stage of cone cornea. After the corneal topography examination, it was found that his corneal curvature had reached 47.9, and the cornea was partially thinned to a thickness of 400 microns. His parents were very worried about this. It is an autosomal dominant or recessive genetic disorder with an incidence of about 0.5/1000, slightly higher in males than females, and most of the adolescent patients; the lesions often cause high irregular myopic astigmatism and varying degrees of visual impairment, and the disease can seriously impair visual function at a later stage of development. The disease often causes high myopic astigmatism and varying degrees of visual impairment. So Xiao Ming is not yet in such a serious situation as corneal transplantation, what treatment should be used at the moment? He is a student with good academic performance and has to enter a major university. According to the physician’s examination, the most suitable treatment for him is conservative treatment, i.e. RGP glasses with conical cornea. Domestic and international studies have shown that more than 90% of patients with conical cornea can significantly benefit from the optical correction and treatment of corneal contact lenses, and the application of specially designed RGP can quickly and effectively improve visual acuity, restore visual function in both eyes, and effectively control the development of lesions. Sure enough, by wearing RGP glasses with conical cornea, Xiao Ming’s vision improved significantly to over 0.8, which is basically the same as the other eye. He can study with other students in class again! He is now very happy, but regular checkups are still necessary. Once an acute change of cone cornea is detected, you should stop wearing RGP lenses and go to the hospital for examination.
