In children with congenital cataracts, after surgical removal of the lens, the eye is in a highly hyperopic state and implantation of an IOL is the most effective way to correct the refraction of the aphakic eye. In children (usually <2 years old), the eye develops very quickly and the refractive error changes relatively quickly, so IOLs are not usually implanted at the same time as the removal of the child's own lens, but rather when the child is older and the eye is relatively stable. What can I do to correct my child's high hyperopia when he or she is aphakic? The first move: wear farsighted glasses to correct your child's farsightedness, the most common way is to wear frame glasses. The advantage of wearing glasses is that they can be replaced at any time as the prescription changes, and they are safe and inexpensive to use. But it also has disadvantages, farsighted glasses will magnify the object image, the child is equivalent to wearing a magnifying glass, see things larger than the real situation, the lens is thick and heavy, there is a distorted image after wearing, small field of vision and other disadvantages. Second trick: wearing corneal contact lenses Another method is to wear contact lenses. At present, foreign congenital cataracts after the removal of the crystal, usually take the method of wearing contact lenses to correct farsightedness, the advantage of which is that you can change the diopter at any time with the development of the child's eye. The visual effect of wearing contact lenses is better than wearing frame glasses, but there are several problems with contact lenses for children. First, removal is the biggest problem, and the older the child gets, the less tolerant he or she is to contact lenses. In addition, it is also a problem for parents to take good care of their children while wearing contact lenses. Not only do they have to take them off every day, but they also have to be checked regularly by a doctor in order to see if the lenses are causing keratoconus, and they have to be replaced regularly as the farsightedness changes, and contact lenses are more expensive. The third trick: implantation of artificial crystals children by wearing glasses can generally meet the normal life and learning, but, highly hyperopic glasses are not as thin as general glasses, it is very thick, after wearing others to see the child's eyes are magnified, easy to attract the attention of other children, affecting the child's mental health. In addition, wearing thick frame glasses, broken glasses can easily cause eye trauma and unsafe. Therefore, IOL implantation is still recommended to make the child's sports activities more convenient. IOL is the best way to provide optical correction, and after implantation, it can provide the quickest reconstruction of post-operative vision, which is also helpful in the treatment of amblyopia. Generally, children with cataracts removed from both eyes can have a second IOL implantation after the age of two. However, considering that children aged two or three years old also have faster eye development, poorer cooperation in pre- and post-operative examinations, and poorer post-operative intraocular response, they can choose to have a second IOL implantation at the age of four or five. For children over two years old with unoperated cataract, cataract extraction combined with IOL can be done at one time.
