Strabismus intelligent correction, i.e. intelligent correction of the posterior migrating suture of the extraocular muscle, has the advantage of free eye position adjustment, intelligent and flexible error correction during the strabismus treatment. Five major concerns of parents before strabismus surgery 1. Will the surgery affect vision? Strabismus correction surgery is now a mature and relatively safe surgery, and most hospitals are now carrying out microscopic strabismus correction, with light post-operative reactions and fast recovery. Strabismus surgery is an adjustment of the muscles on the surface of the eye and will not affect vision. Strabismus surgery is performed outside the eye and usually does not hurt vision. Only a small number of patients may have slight fluctuations in vision in the early stage due to edema and pulling of the extraocular muscles in the short term, which is a normal post-operative reaction. 2.Can the surgery be successful in one visit? Most patients can achieve satisfactory results in one surgery. However, the position and length of the muscles that move the eye are adjusted according to the type of strabismus, the degree of strabismus and other factors of the patient. Due to individual differences, it is possible that the surgery may be undercorrected or overcorrected, and the surgery can be re-corrected if necessary. In some cases, the surgery must be performed in stages because of the complex type of strabismus. 3.Will the strabismus continue after surgery? Will there be recurrence? In some children, the correction of strabismus is very good when they are discharged from the hospital, but after a period of time, parents may find that the child’s strabismus changes, and even some children with exotropia may have internal strabismus, and some children with internal strabismus may have exotropia. Horizontal strabismus: According to the classic textbook of strabismus abroad, the recurrence of intermittent exotropia after surgery is 15%-20% or even 30%. Some children’s strabismus is due to the problem of the central control ability of the brain on the eye muscles. Although the eyes can be corrected to the right position after surgery, strabismus will occur again after a period of time due to the poor central control ability and the poor ability to control the convergence or separation of the child’s strabismus. There are also some children whose visual function has not developed normally or whose visual function of both eyes has been severely damaged since childhood due to early detection (after birth) or long duration of the disease (several years of strabismus). This group of children is very prone to recurrence after surgery, and such children also do not easily recover binocular vision. The literature reports that the incidence of residual and recurrent exotropia after exotropia surgery ranges from 22% to 59%, and the recurrence rate increases with time after surgery (one study found that the recurrence rate can be as high as 60-70% at 20-year follow-up), which is the main reason for the long-term outcome. Therefore, further refractive correction is needed after surgery to improve visual acuity, binocular fusion function, and assembly function training to improve binocular orthostatic control. If the frequency of postoperative exotropia is high, reoperation is usually required. Vertical strabismus: Vertical strabismus surgery is indefinite if it is a problem of the oblique muscles, and it can improve the child’s obvious head tilt through surgery. Therefore, no matter which hospital in China the child is operated, the doctor will explain to the parents before the surgery: strabismus surgery may not be corrected at one time, and the child needs a second or multiple surgeries, which is actually due to the above reasons. 4.Will there be diplopia after surgery? The problem of diplopia after surgery is actually quite understandable, as the eye needs to adapt to a new position, so it is not surprising that diplopia will occur. The child’s visual system is very plastic, so diplopia usually disappears, and if the strabismus is completely corrected, diplopia may promote the development of binocular vision. For adults, the diplopia after surgery can disappear in 1-2 weeks for most people, and very few people will gradually adapt to it without affecting their life and work. 5.Will the surgery leave scars? The strabismus surgery is performed on the conjunctiva of the white surface of the eye, and the longer the surgery is performed, the less obvious the scar will be. However, it will definitely not leave a scar on the eyelid that will affect the appearance. In conclusion, both the patient and the family should have a correct understanding of strabismus surgery, that is, surgery can only correct the eye position and cannot cure the cause of the disease. This is because the root cause of the disease lies in the abnormalities of the centers in the brain that control eye assembly and divergence, and not in the eye itself. Therefore, the possible overcorrection, undercorrection and recurrence of strabismus after surgery should be understood.
