Eye muscle repair surgery is a procedure that corrects a muscle imbalance in the eyes, known as strabismus, where the eyes do not line up properly and look in different directions. The surgery involves shortening and strengthening the muscles by removing a section of the muscles or a nearby tendon (resection), or stretching and reattaching the muscles to a point further back in the eye to weaken them (recession). While eye muscle surgery is usually safe and effective, it is not a permanent solution as vision loss can remain, and patients may still need to wear eyeglasses or contacts for vision problems.
| Characteristics | Values |
|---|---|
| Permanence | Eye muscle repair surgery is not a permanent cure for strabismus. It is also not a cure for poor vision in a lazy (amblyopic) eye. Patients may still need to continue wearing eyeglasses and contacts for vision problems like nearsightedness, farsightedness, or astigmatism. |
| Patient Age | The surgery is most often performed on children, but it is also a successful, safe, and effective treatment for adults of all ages. |
| Anaesthesia | Children usually undergo eye muscle repair surgery with general anaesthesia. Adults are given medicine to numb the area and relax, but some prefer to be awake during the procedure. |
| Surgery Type | To shorten and strengthen the muscles, the surgeon will remove a section of the muscles or a nearby tendon (resection). When the muscles need to be weakened, they are stretched and reattached to a point farther back in the eye (recession). |
| Recovery | The eyes will probably feel scratchy and painful for several days after the surgery. The patient should avoid touching or rubbing their eyes. Antibiotic eye drops or ointments may be prescribed to prevent infection. A follow-up appointment is usually scheduled for one to two weeks after the surgery. |
| Risks | Possible risks include excessive bleeding, infection, double vision, and eye damage. The risk of post-operative infection is higher in very young patients. |

Eye muscle repair surgery is a safe and effective treatment for strabismus
The procedure is usually performed on children, as strabismus is more common in younger patients, but it can also be done on adults with eye muscle problems. Before the surgery, the patient undergoes a complete physical and eye examination, and the doctor determines which muscles are weaker or stronger than they should be. In the case of children, the surgeon ensures the child is healthy enough for surgery and does not have any signs of illness. For adults, the procedure is similar, but they are usually awake and given medicine to numb the area.
During the surgery, the surgeon makes a small cut in the clear tissue covering the white of the eye, called the conjunctiva. Then, the surgeon locates the eye muscle(s) that need to be operated on. To strengthen a muscle, a section of it or a nearby tendon is removed to make it shorter (resection). To weaken a muscle, it is stretched and reattached to a point farther back in the eye (recession). The surgery can be performed on one or both eyes, depending on the patient's needs.
After the surgery, the patient's eyes will likely feel scratchy and painful for several days, and it is important to avoid touching or rubbing them to prevent infection. The patient will need to follow up with their doctor about one to two weeks after the procedure. By this time, their eyes should feel more comfortable and appear normal. In some cases, follow-up treatment or additional vision correction may be required, as strabismus can lead to impaired vision.
While eye muscle repair surgery is generally safe and effective, there are some possible risks, including excessive bleeding, infection, double vision, and eye damage. However, these complications are rare, and the surgery has been shown to improve the way the eyes work together, enhancing stereo (3D) vision and even expanding the field of vision in some cases.

Surgery may be required when non-surgical treatments are ineffective
Eye muscle repair surgery is a procedure that corrects a muscle imbalance in the eyes, causing them to cross inward or outward, known as strabismus. People with strabismus have eyes that don't line up properly, resulting in the eyes looking in different directions. While strabismus can often be treated with eyeglasses or eye exercises, surgery may be required when non-surgical treatments are ineffective.
Strabismus surgery, or eye muscle surgery, is performed to treat misaligned eyes when other treatments have not worked. It is a procedure that loosens or tightens the eye muscles, depending on the issue, to realign the eyes into the correct position. The surgery can be performed on one or both eyes, depending on the problem.
During the procedure, the surgeon makes a small cut in the conjunctiva, which is the clear tissue covering the white of the eye. They then locate the eye muscle(s) that need to be operated on. To strengthen a muscle, a section of it or a nearby tendon may be removed to shorten it, a process called resection. To weaken a muscle, it is stretched and reattached further back in the eye, known as a recession.
The surgery is usually performed as an outpatient procedure, meaning patients can go home the same day. However, it is important to follow the doctor's instructions for pre and post-operative care. Before the surgery, patients may be asked to stop taking certain medications and may need to fast. After the surgery, patients should avoid touching or rubbing their eyes, and the doctor may prescribe antibiotic eye drops or ointments to prevent infection.
While strabismus surgery can improve the alignment of the eyes, it is important to note that it does not fix the poor vision of a lazy eye. Patients may still need to continue wearing eyeglasses or contacts for vision problems such as nearsightedness, farsightedness, or astigmatism. Additionally, in rare cases, eye muscle repair surgery can cause double vision and eye damage. Therefore, surgery is often recommended only when non-surgical treatments have not been successful.

Botulinum toxin is a temporary alternative to surgery
Eye muscle repair surgery is a procedure that corrects a muscle imbalance in the eyes, a condition known as strabismus. The surgery involves shortening and strengthening muscles by removing a section of the muscles or a nearby tendon (resection), or stretching and reattaching muscles to a point further back in the eye to weaken them (recession). While this surgery can help realign the eyes, it is not the only option for treating strabismus.
Botulinum toxin injections, often known by the brand name Botox, offer a temporary alternative to surgery for those seeking to treat strabismus. These injections can be used to weaken specific muscles for a period of six to twelve weeks, with results typically lasting three to six months. This treatment does not require general anaesthesia and can be administered in an office setting. This makes it a convenient option for those who may not be suitable candidates for surgery or who wish to avoid more invasive procedures.
One of the key advantages of botulinum toxin injections is their versatility. They can be employed as a temporary treatment option, for example, in patients with acute cranial nerve palsies, while the surgeon monitors the patient's condition and determines the need for more permanent solutions. Additionally, botulinum toxin injections may be beneficial for patients who experience early overcorrections following strabismus surgery, as they can help manage and adjust the treatment outcome.
However, it is important to consider the variable and unpredictable nature of botulinum toxin injections. The effects may differ from person to person, and the treatment is not suitable as a permanent solution. As the toxins wear off, muscles regain movement, and the initial issue may return. Furthermore, botulinum toxin injections carry their own set of side effects, such as pain, swelling, redness, bruising, flu-like symptoms, and indigestion. Therefore, it is crucial to consult a healthcare provider to weigh the pros and cons of this treatment option and determine if it is the right choice for the individual's specific needs.

Eye muscle surgery carries the risk of post-operative infection
Eye muscle surgery, or strabismus surgery, is a procedure to correct a muscle imbalance in the eyes, causing them to cross inward or outward. While strabismus surgery is considered very safe and effective, like any surgery, it carries risks of complications, including the possibility of post-operative infection.
The risk of post-operative infection can be minimised by treating any pre-existing infections aggressively before surgery, using sterile techniques during the procedure, and administering post-operative antibiotics. However, it is important to recognise the signs of infection, which may include conjunctival injection, eyelid erythema and swelling, a bump over the muscle insertion site, discharge, eye pain, tenderness, fever, and photophobia.
To prevent infection, it is crucial to keep the eyes clean and free of dirt and other irritants after surgery. Patients may be prescribed antibiotic eye drops or ointments to use as a precautionary measure. In addition, avoiding swimming pools, saunas, and hot tubs for at least two weeks after surgery can help reduce the chances of infection.
Although rare, eye muscle surgery can sometimes result in double vision, eye damage, or recurrent misalignment. In some cases, the eyes may return to their pre-surgical state of crossing or wandering, or they may over-correct and move in the opposite direction. Therefore, it is essential to follow the surgeon's instructions for post-operative care to minimise the risk of infection and other complications.

The procedure is usually an outpatient one
Eye muscle repair surgery is a procedure that corrects a muscle imbalance in the eyes, known as strabismus. This condition causes the eyes to cross inward or outward and appear unaligned. The surgery is usually performed on children, but adults with similar eye problems may also undergo the procedure. In most cases, it does not require an overnight stay in the hospital, and patients can go home the same day.
During the procedure, the surgeon makes a small incision in the conjunctiva, which is the clear tissue covering the white of the eye. The surgeon will then locate the eye muscle(s) that need repair. Depending on the desired outcome, the muscle may be shortened and strengthened or stretched and weakened. To shorten and strengthen the muscle, a section of it or a nearby tendon is removed in a process called resection. To weaken the muscle, it is stretched and reattached further back in the eye, in a process called recession.
Eye muscle repair surgery is typically performed under anesthesia. Children usually undergo general anesthesia, where they are asleep and do not feel any pain. Adults are often given medicine to numb the area and help them relax, although some may prefer to be asleep during the procedure. In some cases, adults may receive botulinum toxin injections to temporarily weaken specific muscles without the need for anesthesia.
After the surgery, patients will need to take extra care to prevent infection and avoid touching or rubbing their eyes. The eyes may feel scratchy and painful for several days. Antibiotic eye drops or ointments may be prescribed as a precautionary measure. A follow-up visit with the doctor is typically recommended about one to two weeks after the surgery. At this point, the patient should feel more comfortable, and their eyes should appear normal. However, vision problems may still persist, and eyeglasses or contacts may still be needed.
