The depth of myopia in adults is generally not as deep as that in children and adolescents. If myopia continues to increase with age, we should be careful of signs that cataracts may occur. Myopia is not a patent for young people. Recently, an old man surnamed Xie, who was nearly seventy years old, found that his eyesight was getting worse. A telephone pole is considered as three. Accompanied by his family, he went to the eye clinic for examination and found that the old man was nearsighted by about 300 degrees and was diagnosed as cataract.
Dr. He Jianxian, an ophthalmologist, said that the causes of myopia in the elderly are generally related to cataracts. This kind of cataract is special, and the patient's lens will show uniform nuclear sclerosis, which may cause additional lens effect and increase myopia by 200 to 300 degrees every year. At first, the patient's hyperopia will gradually blur, but myopia will become clear. Some patients mistakenly think that presbyopia has improved at this time. In fact, it is.
A bad sense of distance is also a sign. After a while, he will find that he can't even see things nearby clearly. At this time, it may be time for surgery. The common symptoms of cataract include blurred vision, monocular diplopia, extreme photophobia, glare, occasional color change and poor sense of distance.
At present, there are no effective drugs to treat and prevent cataracts. Therefore, if the patient's cataract is serious enough to obviously affect his daily life, the only treatment is surgical cataract removal and intraocular lens implantation. Dr. He Jianxian also mentioned that at present, the standard surgical method generally adopts "phacoemulsification", which has little surgical trauma and short recovery time. Unless the patient's condition does not allow it, traditional and traumatic surgical methods will be adopted.
