For many myopic friends, they always hope to cure this problem through femtosecond treatment, but they still have to be cautious. Recently, a man in Guangdong who had 300 degrees of myopia before surgery but became 200 degrees of hyperopia after surgery has attracted widespread attention.After the operation, Mr. Li's myopia problem was indeed solved. The effect of the operation was visible to the naked eye, but his eyes faced a new problem, that is, his eyes often suffered from fatigue.
After the above situation lasted for six months, Mr. Li was tested again and found that his vision had become more serious. Not only did he have 200-degree hyperopia, he also suffered from eye fatigue, and his eye adjustment ability also declined.
There are many similar problems. For example, a netizen posted previously that the first batch of patients who underwent RK myopia surgery in 1993, 30 years later, have corrected visual acuity of 0.2 in the right eye and 0.5 in the left eye, combined with presbyopia, cataracts, and 900-degree astigmatism that cannot be corrected. The cornea is ultra-thin with 16 scratches and retinal holes in the fundus.
Tao Yong, chief physician of the Department of Ophthalmology at Beijing Chaoyang Hospital Affiliated to Capital Medical University, once said that true myopia is irreversible, especially if the eyes have developed into high myopia. After the surgery, the risk of high myopia causing malignant complications such as retinal detachment and subretinal choroidal neoducts still exists.
