After congenital cataract surgery to remove the lens, the child’s eyes are in a highly hyperopic state. Since infants and toddlers have relatively fast eye development, they usually do not implant IOLs for the time being, but choose to wear glasses to correct hyperopia and wait for the second phase of IOL implantation after the age of 2. So what should parents be aware of during the time they are wearing glasses? Wear glasses as soon as possible after surgery! If your child’s condition is normal after surgery, you need to have your child examined and fitted with glasses as soon as possible, as it takes some time from optometry, glasses production to fitting in the hospital. When you first start wearing glasses, children are often uncooperative, especially when they are of a certain age, and they are very reluctant to wear glasses and always grab them with their hands. Parents should be careful to reassure the child, and when the child insists on wearing them for a period of time, he or she will slowly adapt and become dependent on the glasses. When the child finds that he or she can see clearly after wearing glasses, he or she will not want to take them off. After wearing glasses, it is important to have regular optometric reviews! Children should visit the hospital regularly after cataract surgery, usually 1-3 days, 1 week, 1 month, 3 months, 6 months and 1 year after surgery. Generally, children of monthly age should be examined and fitted with glasses 1 week after surgery, and once again in three months, because the younger the child, the greater the refractive change, and if there is a change in refractive error, they need to be refitted with glasses. After half a year after surgery, children can be examined every six months, and gradually change to once a year as they grow older. Of course, in special cases, the doctor will adjust the program according to the results of the review. Generally speaking, after the removal of the lens after surgery, the child’s eyes are no longer able to adjust, so the pupil does not need to be dilated during the eye exam, unless the pupil is particularly small after surgery, or even if there is pupillary adhesion, then the pupil needs to be dilated. What’s wrong with using one eye to see after I put on glasses? Some children prefer to see with one eye after wearing glasses. This has an impact on the development of visual function in both eyes. If a child has a monocular cataract, he or she definitely prefers to see with the healthy eye, so the healthy eye must be covered after surgery and amblyopia training must be given to the affected eye. Otherwise, it is difficult to improve the visual function of the affected eye if only surgery is performed without amblyopia training. In children with bilateral cataracts, the development of visual function in both eyes may not be the same either, which is related to the degree and location of preoperative lens clouding, and the occurrence of postoperative complications. Such children are also willing to see in the eye with relatively good vision, and postoperative masking training is also required. All children with cataracts need to be seen by a doctor who specializes in amblyopia after surgery, and rehabilitation will be tailored to each child’s specific situation.
