Dr Ali helped fix my squint, he was very welcoming and extremely helpful throughout the entire process. The fee was well worth it, a life changing surgery that wouldn’t have been possible without him. I highly recommend if you are in need of the same procedure.

I cannot thank Dr Ali and the team enough! I struggled with my squint from about 8 years old, and it progressively got worse. I was told there was nothing that could be done for me on the NHS and that I would just have to live with it. Then I found Dr Ali, who, from the first video call to 8 weeks post surgery, has been nothing short of amazing. So friendly and comforting, and was able to be contacted whenever I needed. He has given me my confidence back, and I am so grateful! If you are considering this surgery, go for it!

I had been suffering from double vision (Diplopia) and was diagnosed with 4th Cranial Nerve Weakness in my left eye in November 2024. A prism was fitted to my glasses and although it helped with the centre of my vision, my downward and far right gaze remained badly affected. By September 2025 my mental health started to become badly affected, I was mentally exhausted and my quality of life was seriously declining. I started to research a surgical solution. I initially used an AI app which rated Mr Ali as the best in his field, I did extensive further research, I found zero negatives. There is a very long waiting list for NHS surgery and getting on the list isn't easy. With all due respect to the NHS, I couldn't wait 3 years for an NHS surgeon, I needed help quickly, I needed the best of the best. By January 2026, I felt I could no longer work, I felt I maybe wasn't capable of doing my job anymore and my GP signed me off sick. I was mentally exhausted, basic tasks such as pouring a drink, ironing, and walking down stairs had became difficult. I eventually arranged an appointment for March 2026. Although video consultation was an option, it was important to me to meet Mr Ali in person so I flew to London from Glasgow. I was initially seen by Orthoptist Rhiannon who did my measurements. I could see the genuine belief she had that Mr Ali would be able to help. I had so many questions I wanted to ask, but by the time the consultation with Mr Ali had ended I didn't need to ask anything, he had covered everything I needed to know. I left the consultation with hope that the nightmare of the previous two years could soon come to an end. I had surgery to realign my eyes on April 13th, I flew to London the day before, stayed overnight in the Travelodge which is a 5 minute walk from Gatwick Spire Hospital and went to the hospital at 7AM on the day of the surgery. A couple of hours after I went back to my room, Mr Ali came in and told me exactly what to expect in the coming days, he gave me his number so I could contact him on WhatsApp if I needed to, but everything went exactly as he said it would, although I didn't need to use it, knowing he was there if I needed him was extremely reassuring. Three days after the surgery when I woke up, I noticed that the TV at the bottom of my bed was single in a position I'd normally have seen double, the 24/7 awareness of the condition in my peripheral vision had completely gone. As the days went on it felt like my central vision had gone from standard definition to 8KHD, this was a huge bonus which I hadn't expected. It is not a painful operation, the following days there's a slight ache and the stitches feel like there is a bit of grit under the eye, it is a very minor irritation, there is a regime of antibiotic eye drops and steroid eye drops, two weeks after the operation there is very little visible evidence that you've even had surgery at all. I'm only on day 25 and the result has already way surpassed my expectations and is most likely to continue to improve. If I had to put a figure on it I would say there is in excess of a 90% improvement in my vision, my functional field of vision is now better than I could have hoped, there is zero double vision, it feels like I imagine the result of laser eye surgery would feel, the blurriness has completely gone, I can now read small print on things like food instructions without glasses (which I previously needed to use my phone to magnify) and was able to return to work a week after surgery. I can see better now without glasses than I could wearing them before surgery. I will be eternally grateful to everyone at London Squint Clinic, and most of all to Mr Ali for the difference this has made to my life. If you are considering making an appointment I strongly recommend doing so. Private surgery is obviously expensive, but you couldn't put a monetary figure on the difference this has already made to my life in such a short period of time. I can now look forward to the future instead of dreading it



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.
Mr Ali has held/holds the following roles at Consultant level:
- Consultant in Squint, Neuro-Ophthalmology and Paediatric Ophthalmology, Moorfields Eye Hospital – City Road, London (2010-2014)
- Consultant in Neuro-Ophthalmology, the Royal London Hospital, London (2010-2014)
- Consultant in Squint, Neuro-Ophthalmology and Paediatric Ophthalmology, Moorfields Eye Hospital – South, London (2014-2023)
- 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
