I had 2 squint operations with Dr Ali and my squint is nearly 100% solved. The last part to be solved with prisms. I would definitely recommend Dr Ali. His pre-assessment and surgery was excellent and put me at ease. Answered all the questions I had. This has made my life easier. Thank you Dr Ali Thanks Mr Bristow

After suffering with double vision for several years and forever changing prescription for prism glasses, I decided to do some research into alternative solutions. After many hours of googling I came across the London Squint Clinic and decided to take the plunge and contact the clinic with a view to making an initial appointment to assess my vision, I booked an appointment to see doctor Ali at his London office, and from the get go he made me feel comfortable and confident that my vision could be corrected. Just a few short weeks after the initial appointment it was off to Gatwick Spire Hospital for the corrective surgery, nervous obviously but feeling hopeful at the same time. One hour in the theatre, back in my room resting before Doctor Ali came by to make fine adjustments, well here we are two weeks later and enjoying single vision for the first time in years, my only regret is I wish I’d have done this sooner, Doctor Ali is a highly skilled specialist and I wouldn’t hesitate to recommend him to anyone. If your a double vision sufferer you know how awful it is, don’t wait for years like I did, do it sooner its life changing.

Cannot express enough how delighted I have been with the whole experience. From the first video consultation with Mr Ali to the sign off, I have been made to feel safe and supported. Mr Ali is amazing he understands not only the physical difficulties caused by having a squint but the emotional impact it can have too. The whole process ran smoothly, knowing there was always someone to contact for information or support was so reassuring. Every stage was explained clearly, the hospital staff were wonderful explaining what would be happening. Mr Ali and team thank you so much for everything.

I’ve received two eye surgeries from Dr Ali, and I can honestly say it has been one of the best decisions I’ve made. So a little bit about me and my need for surgery in the first place, in October 2021 at 26 years of age I had finished work and on my way home but I fell asleep at the wheel and ended up having a single vehicle crash which resulted in me having a brain injury, speech difficulties and double vision. I’ve had four surgeries in total with the first one being mildly successful 04/04/2023 I had some single vision on my upper gaze which meant I adopted quite a lot of head tilt which wasn’t ideal as I had broken my neck in the crash. By the time my eye had totally healed 3-4 months had passed and he had retired so I was placed under the care of a different surgeon. He decided that I would need further surgery to help with the upper gaze being more central which I agreed to as I was keen to continue to make progress. My second surgery was on 09/10/2024, it was unsuccessful in actual fact it was worse than before even the first surgery which I struggled to deal with but at my 2 week post surgery appointment he could see how unsuccessful it was and put me back on the surgery list and I was expecting an appointment for February- March 2025 time I then get a phone call from booking in March and said “we can only see 6 months of appointments and your not on there did you still need/want your appointment if you do we can’t tell you when it will be” and I was just so low and frustrated at this point I had enough so I looked up top squint surgeons in the uk and that’s how I found Dr Ali I have not looked back ever since. The results have been nothing short of amazing. The improvement in my vision has not only been noticeable but genuinely transformative in my day-to-day life. Before his intervention I would be anxious going out in public because my double vision played a massive part in my balance and it was just unbearable. I can’t quite put into words how much this man has helped me and improved my quality of life. Overall, I couldn’t be happier with the outcome. This surgery has given me a new level of freedom and confidence, and I would highly recommend it to anyone on the fence about having it.
I cannot thank Mr Ali enough. Having had squint surgery when I was 6, then 18 and it never really getting fixed, going in to my 3rd surgery at 30, and...
I cannot thank Mr Ali enough. Having had squint surgery when I was 6, then 18 and it never really getting fixed, going in to my 3rd surgery at 30, and choosing Mr Ali and The London Squint Clinic I could not be happier. He showed such empathy, kindness and care when discussing my squint, and throughout the surgery and after. I am incredibly happy with the results and can't thank Mr Ali enough. It really has changed my life in such a positive way, thank you thank you!!



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
