Adult Strabismus Surgery Explained: From Initial Consultation to the Operating Theatre
Why Choose Private Squint Surgery?
In the UK, squint surgery may be performed via the NHS, through insurance, or as self-pay. NHS treatment is free, but waiting times can be long and surgery is often performed by trainees under supervision. Many operations are carried out by surgeons who mainly specialise in children’s squint rather than adult complex cases.
With insurance, fees are standardised — meaning some leading specialists choose not to participate. Self-pay allows you to choose your surgeon directly and prioritise experience, specialisation, and access.
Many centres quote only a surgical fee. Hospital costs, anaesthetic fees and follow-ups are frequently additional. At London Squint Clinic, everything is included in one transparent package.

The adult strabismus surgery process corrects eye misalignment and can resolve double vision, improving function and confidence. This guide explains what to expect, from the initial diagnostic consultation to the surgical procedure and post-operative care.
Understanding the Adult Strabismus Surgery Process
Correcting adult strabismus begins with an initial consultation and diagnosis. This step establishes your needs and goals, allowing a surgeon to create a tailored treatment plan. The process is a collaboration between you and your ophthalmologist to achieve the best alignment and visual outcome.
What is Adult Strabismus Surgery?
Adult strabismus surgery, or squint surgery, adjusts the muscles attached to the outside of the eye to improve alignment. It can restore a conventional eye appearance, improve eye contact, and correct diplopia (double vision). The surgery benefits adults with a lifelong squint, those who developed one later in life, or individuals who have had previous, unsuccessful operations.
Your First Step: The Initial Consultation Explained
During the initial consultation, your surgeon will discuss your symptoms, their effect on your daily life, and your surgical goals. They will then take precise eye alignment measurements using techniques like the prism cover test. These measurements are essential for an accurate diagnosis and form the basis of a personalised surgical plan.
Crafting Your Surgical Plan: Precision and Personalization
After diagnosis, your surgeon develops a precise surgical plan. This customised strategy is based on your specific eye misalignment and details which muscles will be adjusted and by how much.
How Surgeons Decide Which Eye Muscles to Operate On
The decision on which eye muscles to adjust is based on measurements from your consultation. An ophthalmologist assesses ocular motility to identify which of the six muscles controlling each eye’s movement are overactive or underactive. For an inward turn (esotropia), the inner muscle may be weakened (recession); for an outward turn (exotropia), the outer muscle may be weakened. The adjustment is calculated to correct horizontal, vertical (hypertropia/hypotropia), or torsional misalignment.
The Role of Adjustable Suture Technique for Optimal Outcomes
For precision in complex or revision cases, surgeons may use the adjustable suture technique. This method allows for fine-tuning the eye’s alignment hours after the operation, while you are awake. A temporary knot used during surgery can be adjusted later to perfect the eye’s position. This technique increases the likelihood of optimal alignment from a single operation.

Preparing for Surgery: Your Pre-Operative Assessment
Before surgery, a pre-operative assessment ensures you are medically fit for the procedure and anaesthetic. This step identifies and mitigates potential risks for a safe surgical experience.
What to Expect During Your Pre-Operative Assessment
The pre-operative assessment includes a review of your medical history, current medications, and any allergies. Standard tests like blood tests, blood pressure measurement, and sometimes an electrocardiogram (ECG) are performed to evaluate your overall health. A nurse or anaesthetist conducts the assessment, confirms your suitability for surgery, and provides pre-operative instructions, such as when to stop eating and drinking.
General Anaesthesia for Adult Squint Surgery
Adult eye muscle surgery is almost always performed under general anaesthesia. You will be asleep and feel no pain during the procedure. An anaesthetist administers the medication and monitors you throughout the operation. Modern general anaesthesia is very safe, and the anaesthetist will discuss the process with you to answer questions and address any concerns.
The Operating Theatre: What Happens on the Day of Surgery?
Arrival and Final Preparations
On surgery day, you will arrive at the clinic or hospital at a designated time and check in. You will meet with your surgeon, Mr. Nadeem Ali, and the anaesthetist to review the plan and ask final questions. After final checks, you will change into a surgical gown before being escorted to the operating theatre.
The Surgical Procedure: Eye Muscle Adjustment
Once you are under general anaesthesia, the surgeon makes a small incision in the conjunctiva, the eye’s clear surface tissue, to access the eye muscles. The surgeon detaches the targeted muscle(s) and reattaches them to a new position on the eyeball to weaken or strengthen their pulling action. The surgical procedure uses high-precision instruments and takes 45 to 90 minutes, depending on the complexity and number of muscles adjusted.
Life After Surgery: Recovery and Post-Operative Care
Following post-operative care instructions is essential for healing and achieving the best long-term outcome. Your surgical team will provide support throughout this period.
Immediate Post-Operative Expectations and Care
After the procedure, you will rest in a recovery area as the anaesthesia wears off. Soreness, redness, a gritty sensation, and temporary double vision are normal as your brain adapts to the new eye alignment. You will receive lubricating and antibiotic eye drops to aid healing and prevent infection, along with pain management instructions. At the London Squint Clinic, patients have 24/7 WhatsApp access to Mr. Ali for any concerns during initial recovery.
Long-Term Recovery and Follow-Up Appointments
Full recovery varies, but most patients return to non-strenuous activities within a week. Follow-up appointments to monitor progress are typically scheduled at one week, six weeks, and three months post-surgery. With an audited alignment success rate of 95% from one operation, results are typically stable and long-lasting. A re-operation policy is in place for rare instances where further adjustment is needed.

Why Choose a Specialist for Your Adult Squint Surgery?
A specialist in adult strabismus offers the knowledge and skill critical for success, especially in complex cases.
Addressing Complex Cases and Revision Surgery

Some may have been told nothing more can be done. A specialist like Mr. Nadeem Ali, with 24 years of surgical experience and a former consultant role at Moorfields Eye Hospital, focuses on these challenging cases. This expertise in revision surgery and complex strabismus, recognized by bodies like the American Association for Pediatric Ophthalmology and Strabismus, provides effective solutions.
