Most pediatric strabismus requires surgery, and the outcome of surgery is related to the type of strabismus and whether it is accompanied by other conditions. Many children after strabismus surgery will also have to wear glasses, which may be tricorders, nearsighted, farsighted or astigmatic glasses. Strabismus surgery only restores the eye to its proper position and does not change other vision problems. Therefore, children who wore glasses due to refractive error (myopia, hyperopia or astigmatism) before surgery will need to continue to wear glasses after surgery. For children with refractive error, the timing of postoperative lens wear is related to the type of strabismus and the amount of surgery, with most children able to wear lenses immediately after surgery. For children with partially adjusted internal strabismus, the most common type is internal strabismus with moderate to high hyperopia. This type of strabismus can be partially corrected by wearing hyperopic lenses, and the surgery only corrects the remaining strabismus after wearing hyperopic lenses. Therefore, it is necessary to wear glasses as early as possible after surgery to see if the eye returns to the proper position in order to determine whether the surgery is corrected. However, for this type of strabismus, the doctor may adjust the glasses according to the eye position after surgery, so it is not necessary to wear the original glasses, and some children may even take off their glasses early after surgery; on the contrary, some children do not wear glasses before surgery and have good vision, but after surgery, because the eyes have temporary adjustment problems, in order to stabilize the eye position and relax the adjustment, the doctor may temporarily wear 1 to 2D farsightedness for them. With the stabilization of the eye position, most of the glasses can be removed after a period of time, so parents should not worry much. Some children have a small amount of strabismus left after strabismus surgery, which can be corrected by wearing a trigeminal lens, while addressing the residual head tilt. Such children can wear glasses as early as possible after surgery. The trigeminal lenses are mainly for transitional purposes, and when they are worn, they can temporarily correct the residual eye position skew and help restore binocular vision; after the trigeminal lenses are removed, the eye position will still return to the residual skewed state. Therefore, such children need to wear trigeminal glasses for a long time. Since the residual strabismus is often unstable after surgery, it is necessary to follow the doctor’s instructions for regular review during the trigeminal lens wearing period to observe the changes in eye position and make timely adjustments. In some cases, the residual strabismus is too large, so there is a possibility of secondary surgery. Regardless of the type of glasses you wear, you need to follow the doctor’s instructions for regular review. For children who wear glasses due to refractive error, if the post-operative eye position is stable, they can go to the hospital for six months to a year for an eye exam in accordance with the principles of conventional amblyopia treatment; if there is a change in farsightedness, myopia or astigmatism, or a change in eye position, they need to be adjusted according to the doctor’s prescription. Some children wear glasses (farsightedness, myopia or astigmatism) after surgery and stop reviewing them for a year or even two years, and gradually find that the child’s eyes have changed in deviation again. This may be the result of a long period of non-review and a change in prescription without changing the mirror. For example, children with refractive-adjustment internal strabismus rely on distance lenses to maintain their eye position. If the lenses are not reviewed for a long time and the prescription is not reduced as the true prescription of the eye decreases, it can lead to the eye not being able to maintain proper position, so that the strabismus appears again.
