Do you wear glasses? If yes, would you like to have surgery(手术) so you don't need to wear them anymore? Many believe that surgery can fix the problem forever, but that's not always the case(总是如此).
Most people wear glasses because of nearsightedness (近视). When we see things, light comes into our eyes and focuses (聚焦) on the retina (视网膜). But for people with nearsightedness, in their eyes, light focuses in front of the retina. This makes things far away blurry(模糊的) but close things clear.
Surgery can treat this. Xu Jiayi, a 19-year-old student from Beijing, had the surgery five months ago during the winter vacation. "After the surgery, I can see very clearly. Life is more convenient without having to wear eyeglasses," said Xu. However, the process (过程) is not as easy as you might think. Xu said that her eyes hurt badly right after the surgery. Also, she needed to use medicine for at least three months. "At first, there were four types of medicines, then the number became six, she said. These medicines help the eye heal(康复) and prevent eye problems.
Moreover, if you don't look after your eye health well, nearsightedness may return even after surgery. "Because I use my eyes too much both at work and at home, things have started to look blurry to me again," said Du Anni, 32, who had the surgery nine years ago.
Instead of fixing nearsightedness, "the surgery just lets you ‘take off your glasses'" said Wei Wenbin from the Beijing Tongren Hospital in a speech in July. He said that the surgery doesn't fix the changes in the eye's structure(结构).
