Clinically, myopia of more than 600 degrees is called high myopia. High myopia occurs due to genetics, poor eye habits, long hours of close work, and lack of adequate rest for the eyes, which can lead to high myopia over time. Most high myopia is characterized by dilated eyes, elongated eye axes, and a relatively fragile eye structure as the eye expands. With modern technology becoming more and more advanced, what treatments are available for high myopia? The incidence of high myopia is very low during the teenage years. The main focus of this stage is to control the progression of myopia and prevent it from developing into high myopia. A lot of research has proven that wearing keratomileusis (the familiar OK lens) can effectively slow down or even stop the progression of myopia. Youth With the rapid growth of the size, academic workload, myopia may also rapidly deepen, many glasses by high school has grown into high myopia. This period still needs to wear glasses to correct, or you can choose OK lenses to slow down the progression of myopia. If the myopia is stable, you can choose refractive surgery to remove your glasses after your Bar Mitzvah at age 18. After the age of 40, many patients with high myopia begin to develop cataracts and slowly aggravate them. At this time, cataract surgery can be considered to treat cataracts and correct high myopia, killing two birds with one stone. In reality, many patients actually take a chance and try to avoid surgery if they can do without it. This kind of thinking is very harmful. Cataracts can aggravate high myopia, and if they are too severe, even if fundus lesions appear, patients may not have the ability to detect new problems because their vision is too poor, delaying treatment. The structure of the highly myopic eye is relatively fragile, and where is it fragile? It is mainly in the fundus of the eye. As a result of continuous expansion of the eye, the walls of the eye become thinner and the blood supply becomes poorer while retinal fissures and even detachments may occur and retinal atrophy becomes less functional. Therefore, patients with high myopia need regular checkups, preferably every six months with dilated pupils. If you are thinking of having surgery, you need to undergo a thorough examination as well. It is important to mention that our department now also performs posterior scleral reinforcement surgery for high myopia. This posterior scleral reinforcement surgery can strengthen the expanding eye and stop the growth of myopia.
