This page explains what squint surgery is, what happens during the procedure, and what to expect during your recovery.
A squint occurs when the muscles that control the movement of the eyes are too long or too short, causing the eyes to be misaligned and to look in different directions. One eye may look forward, while the other may look up, down or turn inwards or outwards. The condition is also known as strabismus or cross-eyes. A squint can occur all the time or intermittently.
Squints are common in childhood and affect around one in twenty children but can also occur in teenagers and adults. The cause of a squint is often unknown. Some babies are born with the condition, while in other cases a squint can develop later in life.
Untreated squints can cause double vision and may lead to lazy eye syndrome (amblyopia). Lazy eye syndrome occurs when the brain ignores input from the eye affected by the squint and can cause vision to deteriorate in that eye.
Some squints can be treated with non-surgical measures such as glasses, eye exercises, regular monitoring, and an eye patch to strengthen the lazy eye. If these treatments are not successful, surgery may be necessary to correct the squint.
There are several benefits of having squint surgery including:
Your consultant will ask you about your symptoms, general health, and medical history, and perform a full eye examination. They may ask you to look at an object while covering one eye. This is to assess which eye turns, how much it turns and when the abnormal turn occurs.
At Circle Health Group, your first appointment is very important as it's where we get to know you, discuss your expectations for treatment and encourage you to ask any questions you may have. It is important to us that you are as well-informed and comfortable as possible before, during, and after your squint surgery, so please ask your consultant any questions you may have.
After making a diagnosis, your consultant will talk you through all the available options, including whether squint surgery could help you. Together, you'll build a bespoke treatment plan, tailored to your individual circumstances.
Your consultant will tell you everything you need to do to prepare for your squint surgery. If there's anything you're not sure about, or if you have any questions about how to prepare for your surgery, speak to your consultant or call the hospital for advice. Being well-prepared for your surgery will help to ease any anxiety you may have as well as allow your surgery and recovery to go more smoothly.
Before your surgery, tell your consultant about any medical conditions or allergies you have and any medication you are taking, including over-the-counter medicines.
Your consultant may tell you to stop taking some medications like blood thinners before your operation. This is to reduce the risk of bleeding during and after your surgery.
You will not be able to eat or drink anything from midnight on the day of your operation.
Being in optimal health before your surgery can reduce the risk of complications and speed up your recovery.
To make sure you are as healthy as possible before your surgery:
Once the anaesthetic has taken effect, the eye area is cleaned with an antiseptic solution. A device called a lid speculum is applied to your eyelids to hold them open during your surgery.
Your eye is rotated to allow your consultant to access the muscles that move your eyes. The conjunctiva (the layer of tissue over the white of the eye) is cut to expose the muscle.
Your consultant weakens or strengthens the muscles to align them, then they are fixed in place with dissolvable stitches.
Squint surgery normally takes between 40 minutes and an hour.
Sometimes squint surgery needs to be performed on both eyes to ensure they are correctly aligned. Your consultant will let you know ahead of time if this is the case for you.
After your surgery, you will be taken to the recovery room where your heart rate, blood pressure and breathing will be monitored closely until the effects of the anaesthetic have worn off.
When you wake up, you will have an eye pad over your eye to protect it. This is normally removed before you go home.
You will likely have some pain and discomfort and your eye may appear red and weepy after your squint surgery. Your healthcare team will give you medication such as painkillers and eye drops to help you feel more comfortable.
You will be given instructions on how to bathe your eye and apply eye drops in the weeks following your surgery.
Avoid rough or contact sports, swimming, and dusty environments for at least two weeks after your squint surgery. Do not use make-up around your eyes for at least four weeks after your surgery and don't use contact lenses until your consultant tells you it is safe to do so.
Most squint surgery can be done as a day case, meaning you'll go home later the same day. In some cases, you may need to spend one night in hospital.
You will not be able to drive yourself home from the hospital after your squint surgery. Please make arrangements for someone to come and collect you. We can organise a taxi if you prefer, but it's important to have someone to help you when you get home.
How soon you can go back to work after your surgery depends on how you feel after your surgery and the type of job you do. Most people return to work within a week or two of squint surgery.
You should not drive for at least 24 hours after your squint surgery as the anaesthetic may not have fully worn off, and your reaction times may be impaired. After the first 24 hours, you can drive when you have no double vision and can safely control your vehicle and perform an emergency stop. This is normally a few days after your squint surgery.
Recovery from any type of surgery is a gradual process that is different for everyone. Most people can resume normal daily activities one to two weeks after squint surgery.
Possible complications of any surgery include:
Possible complications specific to squint surgery include:
"The main risks of the surgery are that there may still be a squint after the operation because either too much surgery has been done or not enough.
"Some patients experience temporary double vision post-operatively, but in most cases this settles after a few days
"The eye will be red and gritty for a period after the surgery, but this is rarely a serious problem. If you have any concerns, please contact your consultant.
"All risks and complications will be discussed with you in full prior to your procedure."
Dr Alasdair Fern, consultant ophthalmic surgeon at Ross Hall Hospital.
In some cases, your squint can be treated without surgery. Non-surgical methods of treatment such as glasses and eye exercises are normally tried first. Your squint will be monitored to see if it is getting worse. If your squint doesn't improve with non-surgical treatments, your consultant may recommend surgery.
There is around a 5% risk that your squint can come back after surgery. This is because surgery doesn't correct the defect that caused your brain to allow your eyes to drift in the first place. A squint may return shortly after surgery or years later.
Laser eye surgery involves reshaping your corneas with a laser and is used to treat refractive errors such as long-sightedness, short-sightedness, and astigmatism. You can have laser surgery if you have a squint, but it will not treat your squint or affect it in any way.
Squint surgery normally takes between 40 minutes and one hour.
Squint surgery in adults is normally very successful and around 80% of adults have satisfactory alignment after one operation.
Squint surgery is performed under general anaesthetic which means you'll be asleep during the procedure and won't feel any pain. You can expect some soreness and discomfort for a few days after your squint surgery. Take over-the-counter painkillers like paracetamol or ibuprofen if you need to.
Squint surgery is a relatively safe procedure, but as with all surgical procedures, there is a small risk of complications. Your consultant will explain all the possible risks and complications to you before your operation. It's important that you are fully aware of all the possible risks and complications before your surgery so that you can make an informed decision.
