Surgery to correct crossed eyes, also known as internal strabismus correction surgery, is a very routine procedure in ophthalmology and usually costs about $3,000-5,000. In the case of children, the cost is relatively higher because children are younger and are not able to cooperate with local anesthesia, so they are usually required to be operated under general anesthesia, which will increase the cost of anesthesia, usually around 2,000 yuan. The development of the visual function of the eye can be seriously affected by crossed eyes, so it is important to detect and treat this condition as early as possible. For the treatment of internal strabismus, there are two main methods: the first is surgical treatment; the second is conservative treatment. The first is surgery, and the second is conservative treatment. This condition is mainly for the adjusted internal strabismus, which refers to the presence of refractive errors, such as farsightedness or astigmatism, leading to the occurrence of strabismus, which can be corrected by wearing glasses.
