Risks and sequelae of strabismus surgery 1. Will the surgery affect my vision? Strabismus correction surgery is now a mature and relatively safe procedure that will not affect vision. Strabismus surgery is performed outside the eye and will not affect vision as long as the patient cooperates and does not move around. Only a small number of patients have slight fluctuations in vision in the short term due to edema and pulling of the extraocular muscles, which is a normal post-operative reaction. 2.Can the surgery be successful at once? 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 under-corrected or over-corrected, 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 I still have strabismus after surgery? Some patients with poor vision may develop exotropia in the long term. The long-term regression rate of exotropia is about 15-20%, but it usually does not recur within a short period of time. The main way to reduce the regression rate is to make a mild overcorrection in the near future after surgery, that is, to make a mild internal strabismus of about 5 degrees, so that the appearance is not too obvious internal strabismus, and a rough prediction can be made before surgery according to the data of the examination. 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, we should understand the possible overcorrection, undercorrection and recurrence of strabismus after surgery, and should not blindly have too high expectations of the results of strabismus surgery!
