Here's the thing. I found your hospital after seeing Professor Tang's cataract needle aspiration. I would like to ask if it is not necessary to change the lens when pulling the needle. I have consulted many western doctors, but many of my neighbors have had poor results after changing their lenses, and all of them have different sequelae, including the patients I visited in the hospital. Most of the operations are not ideal. It seems that people's eyes can be operated twice in their lifetime. So I'm really afraid to try this crystal substitute easily. I am desperate. Fortunately, I saw what Professor Tang said about pulling out the needle for Chairman Mao. Looking for a lot of information, I didn't find any mention of changing the crystal. I just said scraping cataracts. I didn't expect our Chinese medicine practitioners to be so powerful that my family and I saw hope again. So please help us and give us some advice. We just want to do this operation without changing the crystal. Even if the postoperative effect reaches 60%, we are willing to try. I wonder if this operation is original? If not, can you give us an accommodation? Now your hospital is really the last hope for our family. Help us. I appreciate it. Thank you.
