This is a surgical procedure that consists of modifying the muscles that surround the eye and aligning them in such a way that corrects the crossing of the eyes. It involves “strengthening” some muscles and “weakening” others in order to reach the aligning of the eyeball.

Rectus resection surgery: is the procedure where the muscle is placed in a different position. It can be done over the lateral or vertical rectus muscles to correct deviations. This technique aims to achieve the parallel alignment of both eyes.
Muscular recession: A recession consists of altering the attachment site on the eyeball. A suture is placed through the muscle at the attachment site to the eye. The muscle is detached from the surface of the eye and reattached further back from the front of the eye. This procedure can be done on the lateral or vertical rectus muscles.

In some cases, the eyes are not left perfectly aligned and various surgeries are needed. Other complications such at the bleeding of the eye, an infection or the side-effects of anesthesia can also arise.
DURATION:
The procedure lasts, on average, about 30-60 minutes

A strabismus patient can return to normal day to day activity except rough movements or exercise two days after the procedure. The day following the surgery, the patient must go in for a follow-up appointment. There will be redness of the eyes for about two weeks after the surgery, which can be alleviated with the use of lubricated eye drops. During this postoperative process, the patient may feel a strange object in their eye or a “pulling: sensation when he moved the eyes. This feeling might last for up to three days.
