How does child cataract return a responsibility?

summary

Congenital cataract is a common eye disease in infants. Congenital cataract refers to partial or total lens opacification in the first year after birth. The first is the birth of cataract, known as congenital cataract. The second kind of cataract occurs only a few weeks or months after birth, which is called infantile cataract. Let's take a look at the following.

How does child cataract return a responsibility?

First: exogenous factors: is the main cause of congenital cataract. Such as maternal infection in the first two months of pregnancy, or suffering from rubella, chickenpox, measles, mumps and other infectious diseases within six months of pregnancy, causing damage to the fetal lens. Thyroid insufficiency, malnutrition, vitamin deficiency can cause congenital cataract. In addition to cataract, some patients also have congenital malformations such as iris defect, microphthalmos or hypoplasia of brain.

Second: endogenous factor: refers to the chromosomal gene variation, causing the lens embryo development process disorder, hereditary and family history.

Third, cataract surgery in children is very difficult. Because the eyeball is soft, the wound is easy to leak, and the anterior capsule of the lens is highly elastic, it is not easy to maintain the integrity of the opening of the anterior capsule when opening the anterior capsule; In addition, the available intraocular lenses are not specially customized for children. Many children with cataract do not have intraocular lens implantation at the same time after undergoing lens extraction surgery, so the eyes are like a camera without lens. They need to wear 1500-2000 degree hyperopia glasses to help focus after surgery, and then wait for one to several years before the second implantation of intraocular lens. However, the image obtained through glasses is better than normal, and the visual effect is not satisfactory. Amblyopia is more likely to occur, and amblyopia may also be accompanied by strabismus.

matters needing attention

Pediatric cataract surgery has ultra-high requirements for doctors, in the operation of the lens accurate measurement and operation position control is very strict, only step by step in order to ensure that children can recover to high quality vision, inexperienced doctors give children cataract surgery, postoperative recovery of vision effect will be relatively poor. Therefore, the selection of experienced doctors and experts is the key factor for the success of the operation.
