Before deciding to have surgery, I was understandably nervous and uncertain. Eye surgery is not something you take lightly, but any concerns I had quickly disappeared after meeting Dr. Ali and his team. From my very first consultation, they were professional, reassuring and took the time to answer every question I had, leaving me feeling completely confident that I was in the best possible hands. The surgery itself was far more straightforward than I had imagined. In my case, everything went smoothly, and I was able to leave the clinic early that same afternoon. The results have exceeded my expectations. For many years I had been very self-conscious about my squint, particularly whenever photographs were taken. It was something I was always aware of and often tried to hide. Since the surgery, that self-consciousness has gone. It has genuinely changed how I feel about having my photograph taken and has given me a confidence I didn't expect to regain. What has impressed me just as much as the surgery itself has been the aftercare. Dr. Ali's support throughout my recovery was exceptional. Whenever I had a question or concern during the healing process, he responded incredibly quickly and was always reassuring. Knowing that level of support was there made the recovery much easier. I cannot thank Dr. Ali and everyone at the London Squint Clinic enough. My experience from start to finish has been outstanding, and I would not hesitate to recommend them to anyone considering squint surgery.

Absolutely amazing service from start to finish! Having had multiple previous surgery from a little child and countless years of trying through the NHS and private for further review with always a negative outcome. I finally took the plunge to contact Dr Ali & team and completely amazed by the results! The customer service, kindness and support I’ve received was second to none and I couldn’t have wished for a better outcome! Even with having to move my surgery date due to illness, nothing was too much trouble and it was resolved extremely quickly with a new date! I can’t thank the team enough especially DR Ali for the compassion and outcome! Highly recommended!

I recently had squint surgery at the London Squint Clinic and I'm extremely happy with the results. From the first consultation through to the surgery and aftercare, the team were professional, reassuring and supportive. Mr Ali explained everything clearly, which made me feel confident and comfortable throughout the whole process. The surgery went smoothly, and the care I received afterwards was excellent. I am really pleased with the outcome and grateful for the difference it has made. I would highly recommend The London Squint Clinic to anyone considering going ahead with surgery.

I am so pleased with the result of my surgery, and would highly recommend Mr Ali. The whole process end to end was really smooth, and I felt very supported and listened to throughout. My quality of life has improved hugely - thank you!

I honestly don’t know how to write this review without sounding dramatic but I think this is one of those times where dramatic is completely justified. I first booked an appointment with Mr Ali at the London Squint Clinic in May 2025. At that point, I had already lived with eye problems for most of my life. My first eye turn was when I was around 4 years old and since then I feel like I have done the full strabismus bingo card: corrective surgery as a child, glasses, patches, Botox, atropine drops, the lot. Before seeing Mr Ali, I had been told on the NHS that nothing could really be done and that surgery was too risky. I was also honestly told that it was in my head by some doctors and that I needed to focus or I was making it worse than it is. I accepted that for a long time because when you are told something is not possible, you believe it. But knowing the outcome I have had now, I genuinely wish I had explored it sooner. I came to Mr Ali knowing that my case was not simple. He operated in June on one eye, then another operation in September on the other eye. 2 months ago I had my third and final surgery with mr Ali - That might seem a lot but we were cautious of over correction because at this point I was already chuffed with the outcome. at one point my eyes looked beautifully straight, but I still had double vision when looking to the left. Anything to the left of my central vision was double and It affected so much more than people realise. I couldn’t drive properly with double vision. If I had one eye patched, even if technically I could legally drive, I didn’t feel safe or confident. I would bump the curb and scratch my tyres because my judgement just wasn’t right. I now drive confidently. That alone has changed my life. I can now sit and have a conversation with someone on my left. I can look someone in the eye without having to alternate between which eye has focus. I don’t have to overthink where I am looking or whether the other person can tell. I don’t feel like I am constantly managing my vision and my face at the same time. Before this, I had tried Botox injections and had drooping eyelids. I had a haemorrhage in my eye that lasted over a month. It is exhausting. It makes you want to hide. What I appreciated from the beginning was Mr Ali’s honesty. He never overpromised. He explained things clearly. I always felt informed and respected. I think he understood that I knew things were complicated, and I appreciated his approach of: we will do our absolute best and I knew he meant it. I can honestly say the result has changed my life. Mr Ali’s post-operative care is unlike anything I have experienced before. He is reassuring, calm and goes above and beyond. I am also one of those rare people who seems to be allergic to absolutely everything, especially eye drops, because apparently I like to keep medical professionals on their toes. So thank you for dealing with me being so complicated again on top of it all. The impact has been far bigger than cosmetic. I don’t feel shy in groups now. I don’t hide from photographs, video calls or people looking at me. My confidence at work has improved. I contribute more. I don’t shy away from being on camera or being seen. For anyone who has lived with a squint, double vision, or a misalignment of the eyes in any way you will understand that this is not vanity. It affects how you move through the world. It affects driving, conversations, eye contact, confidence, work, social situations and whether you feel comfortable being noticed. Mr Ali has given me something I honestly did not expect to get - ever. Thank you, Mr Ali, for your skill and for changing my life.

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.

- Lead for Adult Squint, Double Vision and Neuro-Ophthalmology, Moorfields Eye Hospital – South, London (2016-2023)
- Honorary Consultant to the National Hospital for Neuro-Disability, London (2021-2023)

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
- having your photo taken
