Time to say goodbye to double vision

Get out of prism glasses with surgery

Reclaim single vision

Imagine being able to wake up and see everything clear and single. No more double objects, blur, difficulty judging distances, tackling steps, problems reading. No more confusion from things on the side appearing in front of you. We take single vision for granted. Only people with double vision appreciate what it would mean to get that back.

Remember the life you used to have

Get back to enjoying all the things which double vision took away: reading for pleasure, outdoor activities, sports, driving. Double vision doesn’t just affect your eyes, it constricts your life. And you get used to it just because you have to. But with double vision surgery you can once more live the life you used to enjoy.

Throw away your prism glasses

Prism glasses can be good for some people. But for others they are just a pain. They don’t fix the problem in different directions or distances. They don’t work great for when you are moving about. Costly, thick, heavy and always need updating. And once you are in them, you are trapped. Unless you have double vision surgery. Most of our patients can get rid of their prism glasses after surgery and return to how they used to see before: no-prism glasses, contact lenses, or nothing.

DOUBLE VISION SURGERY OFFERS HOPE

When our patients are first told that they can have double vision surgery, it is often a very emotional moment. Finally they have hope that their double vision will come to an end and they can get back to a normal life.

Who is Mr Ali?

Mr Nadeem Ali is a world expert in the diagnosis and surgical treatment of Double Vision.

There are many eye surgeons who do mainly cataract and a bit of 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 and double vision 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)
  • Visiting Consultant in Squint Surgery, Gibraltar Health Authority (2018- present)

Double vision surgery Frequently Asked Questions

Double vision suitability criteria

To be a good candidate for double vision surgery, you should meet the following criteria:

  • Be between 18 and 100 years old.
  • Experience double vision, which means you see two images of one object.
  • Or experience visual confusion, which means objects appear in the wrong place.
  • You might or might not have a visible eye turn or squint.
  • You might or might not have tried prism glasses, which are special glasses to help with double vision.
  • You may have been denied surgery through the NHS.
  • You may have been told that surgery is not an option elsewhere.

Double vision surgery aims to fix misalignment in the eyes that causes seeing two images of one object.

During the surgery, the eye muscles are adjusted to improve their alignment. This can involve tightening or loosening the muscles to correct their position. The goal is to make both eyes work together, so you see a single, clear image instead of two.

Recovery involves some rest and follow-up visits to ensure the eyes are healing properly and functioning well together.

Advantages:

  • High Success Rate: 95%, meaning most patients see significant improvement.
  • Quick Procedure: Usually completed in less than an hour.
    Anesthesia Options: Choice of local or general anaesthesia.
  • Short Wait Time: Surgery can be done within a few weeks from the first consultation.
  • Day Case Surgery: No overnight stay required.
    Immediate Benefits: Many patients notice improvement from day 1.
  • Minimal Pain: Most patients experience very little discomfort afterward.

 

Disadvantages:

  • Low Risk of Complications: Very rare, less than 1 in 1,000, but risks such as infection or adverse reactions to anaesthesia are possible.
  • Temporary Discomfort: 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.

Double vision 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, affecting less than 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.

Prism glasses:

Prism glasses bend light to correct its path, aligning images on the retina and reducing double vision by helping the brain merge them into one clear view.

Botox:

Botox injections can also alleviate double vision temporarily by relaxing eye muscles. However, Botox requires repeated treatments every few months and can worsen vision initially, 

Double vision surgery offers a more stable and permanent solution.

  1. Book an initial video consultation to see if surgery is right for you and discuss your options.
  2. Get pre-surgery measurements, which can be done in London or in several locations in the UK or beyond. Sometimes, these can be taken on the day of surgery.
  3. Undergo the surgery as a day case, meaning you don’t stay overnight.
  4. Say goodbye to prism glasses and start enjoying clear vision right away!
  5. Attend two follow-up appointments, one in 2 weeks and another in 2 months, to check your progress and healing.

Getting your freedom back

  • Freedom from prism glasses
  • Freedom to drive
  • Freedom to read
  • Freedom to work on a computer
  • Freedom to enjoy sports and hobbies
