I am extremely happy with the result of my squint surgery and would highly recommend Mr Ali. I am an adult who had never experienced any symptoms or even been aware that I had a squint. However, I suddenly developed rapidly worsening vision and persistent double vision due to a decompensated squint. In less than two months, I went from having perfectly straight eyes to having a very noticeable squint in one eye and significant double vision. Receiving this diagnosis and being told that surgery was required was quite daunting initially. Undergoing eye surgery is a significant decision, and I wanted to make sure I chose the right surgeon. I did extensive research and met with several specialists in London before ultimately choosing Mr Ali because of his extensive experience, focus and high volume of adult squint cases, and expertise with adjustable sutures. I genuinely believe I could not have made a better decision. From my first appointment, Mr Ali provided reassurance and his experience, thoroughness, and the way he cares for his patients made me feel that I was in very safe hands. He was always patient and willing to answer my (many) questions, while providing helpful context and explaining things clearly. I had my surgery less than two months after my diagnosis and had an excellent experience throughout, from the pre-operative appointments through to surgery and recovery. The post-operative suture adjustment to fine-tune the alignment was initially a little daunting, but I felt reassured throughout and the whole process went very smoothly. The care I received after surgery was equally excellent. Mr Ali was very responsive, answered my questions promptly, and actively checked in on my recovery. Knowing that I could contact him directly was extremely reassuring. The cosmetic result has been excellent, but most importantly, my double vision has completely disappeared and my vision has improved significantly. Now, a little over two months after surgery, I am extremely happy with both the result and the healing process. I feel that I am seeing at least as well as I did before my problems began, and possibly even better. My depth perception has also improved, and I have realised that some of the limitations I had previously experienced were things I had simply assumed were normal for me. I am very grateful to Mr Ali and his team for their expertise, reassurance, and care throughout the entire process. What initially felt like a very frightening experience turned into a remarkably positive one.

I was understandably apprehensive about getting eye surgery, but Mr Ali really lived up to his incredible reputation. I was referred to him by the Belfast Cathedral Eye Clinic, who spoke very highly of his results. From the beginning, Mr Ali clarified expectations and answered all my questions in detail. His communication skills and humanity are plain to see. The whole process was unbelievably smooth. I wish I hadn’t worried at all! Do yourself a favour and book yourself in for a consultation with him. He has massively improved my vision, and I could not be more grateful!

I recently had surgery at the London Squint Clinic for a squint I had since childhood. From my first consultation to the day of surgery everything was straightforward. Everyone at the clinic was friendly and approachable. I am so pleased with the results and already feel more confident. For anyone having the adjustable sutures with their surgery, this was something I was apprehensive about but Mr Ali put me at ease and I honestly could not feel a thing. Thank you to Mr Ali and his team. I definitely wish I had done it sooner!

I had squint surgery a few weeks ago and could not be happier with the results, it has transformed my life. Initially I was apprehensive at having surgery on my eye but there was absolutely nothing to worry about. Mr Ali explained everything in detail to me and was calm and reassuring every step of the way. I no longer have to worry about all the things I did before such as where I could sit when out with a group so I didn’t have to look to my left. I worried constantly that people noticed my squint and it was affecting my confidence. This surgery has had such a dramatic difference to not only my vision but how I feel and see myself. Everything went so smoothly on the day, I was operated on in the morning and home by mid afternoon. For anyone suffering with a squint please go and see Mr Ali, he is such a kind and caring person. I really can’t thank him enough.

I had double vision that was getting increasingly worse. I have to admit that I was sceptical about what could be achieved and Mr Ali was always honest with me about potential results. The outcome is amazing. After years of increasing prisms (+16) I now manage without. It really has been truly transformative . Wish I’d known about this clinic years ago. Can’t praise them highly enough.



Regain your self-confidence
Squint stops people seeing the real you. When you have a squint, you can’t look people in the eye, can’t have photos taken, don’t like online meetings, don’t like meeting new people. When you know your eyes are holding you back in life, it’s time to be free from the burden of squint.


Confidence starts with clear vision
The constant worry about how your eyes look is gone. No more avoiding eye contact or feeling self-conscious in conversations. The anxiety of being judged disappears, replaced by newfound confidence. You feel lighter, free from the emotional weight of your squint. For the first time in years, you feel like yourself.
Wake up to a new you
You wake up, look in the mirror, and smile—your eyes are straight, and your vision is clear. You walk into a café, meet a friend, and feel at ease, no longer worrying about where to look. At work, you present with confidence. Life feels simpler, smoother, and full of possibilities.


Be seen the way you were meant to be
Friends and family will notice something different—your newfound confidence. They’ll see you making eye contact, engaging naturally, and smiling more. You’ll come across as more self-assured, comfortable in your own skin. Instead of focusing on your squint, people will see the real you—bright, confident, and ready for anything.


Emma’s story as featured in Women’s Health Magazine
Our patient Emma shared her squint surgery story in this informative article.
Meet your surgeon
Mr Nadeem Ali is a world expert in the diagnosis and surgical treatment of Squint (Strabismus).
There are many eye surgeons who do mainly cataract and a bit of adult squint surgery on the side. There are many who do general ophthalmology for children and a bit of kids’ and adult squint surgery on the side.
But there are very few people in the world who specialise 100% in squint surgery in adults. Mr Ali does just that.
He holds the following degrees:
- MA – Triple First class (Cambridge). He was top of the year for 2 out of 3 years.
- MB BChir with distinction (Cambridge)
- MRCOphth (Royal College of Ophthalmologists, London)
- FRCSEd(Ophth) (Royal College of Surgeons, Edinburgh).
Born in the North East of England, Mr Ali attended the Royal Grammar School, Newcastle-upon-Tyne.
He studied medicine at the University of Cambridge and graduated with a Triple First Class degree.
His College, Gonville and Caius, was the leading medical college at the University and boasts alumni such as William Harvey (who discovered the circulation of the blood) and Francis Crick (who discovered DNA). During his undergraduate years, he was selected for a Summer Research Programme at Cold Spring Harbor Laboratory, New York, the labs of James Watson (the other discovered of DNA), where he studied the developing visual system with Neuroscientist Prof Hollis Cline. He also completed his undergraduate degree in Neurophysiology, conducting research with Prof Roger Carpenter, a pioneer of eye movement research.
He won 15 academic prizes and was top student of the University in medicine for two years of his course. He was also awarded the prestigious Schuldham Plate, given to the top-performing student over all academic subjects, over the three years of undergraduate study.
He completed his medical school at the University of Cambridge Clinical School, graduating with distinction.
Mr Ali completed his general Ophthalmic training in the North East of England.
He then pursued a Fellowship with Mike Clarke, a world-expert on squint and double vision, who taught him much of what he knows.
After that, he undertook a fellowship in Neuro-Ophthalmology at the National Hospital for Neurology and Neurosurgery, Queen Square wher he gained experience in complex neurological causes of double vision.
He also did a Fellowship Squint and Double Vision surgery at the world-renowned Moorfields Eye Hospital in London.
He was then uniquely privileged to undergo a further 18 months of advanced, 1:1 training in squint and double vision surgery with Mr John Lee (deceased), probably the world’s leading squint expert.
He was then one of the youngest Consultants at that time appointed to the role of Consultant Eye Surgeon at Moorfields Eye Hospital.
He worked as Consultant at Moorfields for 13 years from 2010-2023, receiving referrals of complex cases in squint and double vision from across the country.

Squint surgery Frequently Asked Questions
To be a good candidate for squint surgery, you should meet the following criteria:
- Be between 18 and 100 years old.
- Have a visible misalignment of the eyes which affects your life.
- You may have had no previous squint surgery, or had multiple previous operations.
- You may have been denied surgery through the NHS.
- You may have been told that squint surgery is not an option elsewhere.
Squint surgery aims to realign the eyes so they look normal.
During the surgery, the eye muscles are either tightened or relaxed to change the pull on the eyeballs. This changes the alignment of the eyes. At no point is your eye taken out. It’s all done through micro-incision surgery.
Advantages:
- High Success Rate: Overall 95% of our patients achieve success from a single operation.
- Quick Procedure: Surgery is usually completed in less than an hour.
- Anaesthesia Options: General anaesthetic is the norm, but you can also have surgery under local anaesthesia as well.
- Short Wait Time: Surgery can be done within 3 weeks from the first consultation.
- Day Case Surgery: No overnight stay required.
- Immediate Benefits: Many patients notice improvement from day 1, but it does take a few weeks for the eyes to settle down.
- Minimal Pain: Most patients experience very little discomfort afterward. A couple of days of paracetamol is all most patients need.
- Rapid rehabilitation: You can return to normal daily activities after a day, you can exercise after two days, you can return to work after 1-2 weeks.
Disadvantages:
- Low Risk of Complications: Like all surgery, the risk of complications is not zero. The risk of vision loss in an eye is about 1 in 4000.
- Not perfection: We aim for a significant improvement in eye alignment but can’t achieve 100% perfection. Still, what we normally achieve is life-changing.
- Healing time: It takes about 8 weeks for the eyes to feel fully back to normal.
- Irritation: The stitches we use take 6-7 weeks to dissolve and the eyes can feel scratchy during that period, but it improves week by week. Some patients may experience mild pain, swelling, or discomfort.
- Potential Need for Further Adjustments: Not all patients achieve perfect results and may need additional procedures. Your risk of this will be explained at your appointment. For all patients combined it is around 5%.
Squint surgery is very safe, even safer than cataract surgery.
However, like any surgery, there are some risks. These include:
- Overcorrection or undercorrection, where the problem might not be fully fixed.
- The need for another surgery, in about 5% of cases.
- New or ongoing double vision, in about 2% of patients.
- Loss of vision, which is very rare, about 1 in 4,000 people.
- Redness or scarring on the white part of the eye.
- A slight change in the shape of the eyelid.
Overall, the risks are low, and most patients see great results.
Besides surgery, or leaving things alone, the other option is Botox injections.
Botox injections can make the eyes straighter for a period of a few months. However, Botox requires repeated treatments every few months and can worsen vision initially,
Surgery offers a more stable and permanent solution.
- Book an initial consultation to see if surgery is right for you and discuss your options.
- Get pre-surgery measurements, either local to you or in London. Sometimes, these can be taken on the day of surgery.
- Undergo the surgery as a day case, meaning you don’t stay overnight.
- Put in your post-op drops for 6-7 weeks.
- Attend two follow-up appointments, one in 2 weeks and another in 2 months, to check your progress and healing.
- Enjoy the results of your surgery!
Successful squint surgery:
- increases your self-esteem
- increases your confidence
It makes you more confident:
- making eye contact
- meeting new people
- in your relationships
- in your career
- in making presentations
- in online meetings
