Understanding the Different Types of Laser Eye Surgery in the UK: A Comprehensive Guide
For many people living with refractive errors, the prospect of waking up with clear vision without reaching for glasses or contact lenses is a life-changing ambition. Laser eye surgery in the UK has become one of the most frequently performed elective procedures, backed by decades of clinical advancement and high patient satisfaction rates. However, as technology has evolved, so has the terminology.
Patients researching their options often find themselves overwhelmed by an alphabet soup of acronyms: LASIK, LASEK, and PRK. While they all aim to reduce dependency on corrective eyewear, they are distinct procedures with different surgical approaches. Understanding the different types of laser eye surgery available is the first step toward a productive conversation with a specialist. It is important to note that there is no “best” procedure—only the one most clinically appropriate for your unique ocular anatomy.

What Is Laser Eye Surgery?
At its core, laser eye surgery—also known as refractive eye surgery—is a procedure designed to reshape the cornea, the clear front part of the eye. The cornea acts like a lens, focusing light onto the retina at the back of the eye. When the shape of the cornea is imperfect, the light doesn’t focus correctly, resulting in blurred vision.
Common refractive errors include:
- Myopia (Short-sightedness): The eye is too long or the cornea too curved, making distant objects blurry.
- Hyperopia (Long-sightedness): The eye is too short or the cornea too flat, making near objects blurry.
- Astigmatism: The cornea is shaped more like a rugby ball than a football, causing distorted vision at all distances.
During laser vision correction, a cool-beam excimer laser is used to remove microscopic amounts of tissue to “re-sculpt” the corneal surface, allowing light to be focused accurately. According to the Royal College of Ophthalmologists, over 95% of patients are satisfied with the outcome of their surgery, provided they were correctly screened for suitability.
Types of Laser Eye Surgery Available in the UK
In the UK, the most prevalent techniques are LASIK, LASEK, and PRK. While newer methods like SMILE exist, these three remain the cornerstones of the industry. The primary difference lies in how the surgeon accesses the middle layer of the cornea (the stroma) to perform the reshaping.
LASIK Laser Eye Surgery
LASIK eye surgery in the UK is the most common form of vision correction. The procedure involves two steps. First, the surgeon creates a thin, hinged flap in the outer layer of the cornea using a femtosecond laser. This flap is gently folded back to reveal the underlying tissue. Second, an excimer laser reshapes the cornea before the flap is repositioned.
LASIK is often favoured because:
- Rapid Recovery: Many patients report significantly improved vision within 24 hours.
- Comfort: Because the outer epithelium is preserved (as part of the flap), post-operative discomfort is typically minimal.
- Versatility: It can treat a wide range of prescriptions.
However, LASIK may not be suitable for everyone, particularly those with very thin corneas or those who participate in high-contact sports, where the risk of flap displacement though rare must be considered. You can learn more about our specialist surgeon Mr. Manu Mathew’s approach to these procedures.
LASEK Laser Eye Surgery
LASEK eye surgery (Laser-Assisted Sub-Epithelial Keratectomy) is a surface-based procedure. Unlike LASIK, no permanent flap is created. Instead, the thin outer layer of the cornea (the epithelium) is softened with a diluted alcohol solution, lifted, and pushed aside. After the laser reshaping is complete, the epithelial layer is smoothed back over.
This procedure is often recommended for patients who are not candidates for LASIK due to:
- Naturally thin corneas.
- Dry eye syndrome (as LASEK is thought to disrupt fewer corneal nerves).
- Lifestyles or professions involving high impact (e.g., military or boxing).
Recovery from LASEK is generally more gradual than LASIK, as the surface layer needs time to heal.
PRK Laser Eye Surgery
PRK eye surgery (Photorefractive Keratectomy) was the original form of laser vision correction. Similar to LASEK, it is a surface procedure. The difference is that the epithelial layer is completely removed rather than being moved to the side. The laser reshapes the tissue, and the epithelium then regrows naturally over the following days.
While it is an older technique, it remains highly relevant today. It is often the safest choice for patients with irregular or extremely thin corneas. While vision improvement can be more gradual—often taking a few weeks to reach its peak—the long-term visual outcomes are comparable to LASIK.
LASIK vs LASEK vs PRK – Key Differences
Choosing between these different types of laser eye surgery involves weighing several factors. While LASIK offers the “wow” factor of near-instant results, surface treatments like LASEK and PRK offer a robust solution for those with specific corneal geometries.
- Technique: LASIK uses a flap; LASEK/PRK treat the surface.
- Comfort: LASIK patients usually feel a “gritty” sensation for a few hours. LASEK/PRK patients may experience discomfort for 2–4 days as the surface cells regenerate.
- Stability: Surface treatments (LASEK/PRK) leave the structural integrity of the cornea more intact, which is why they are often preferred for thin-cornea patients.

Laser Eye Surgery Cost in the UK
When researching laser eye surgery cost in the UK, patients will find a wide range of pricing. In the UK, the cost typically ranges from £1,200 to £3,000 per eye, though “budget” providers may offer lower entry prices that often exclude essential aftercare or advanced technology.
Several factors influence the laser eye surgery uk cost:
- Procedure Type: Advanced femtosecond LASIK may cost more than traditional surface treatments.
- Technology: The use of wavefront-guided lasers, which map the eye in 3D for a bespoke treatment, can increase the price.
- Surgeon Experience: Highly specialised consultant surgeons often have higher fees reflecting their expertise and lower complication rates.
- Aftercare: Comprehensive follow-up care is vital for safety and is usually bundled into the price of premium providers.

Does Laser Eye Surgery Cost More in London?
It is a common observation that laser eye surgery in London, UK, often carries a premium. This is frequently attributed to higher overhead costs, such as clinic rent in Harley Street or the City, and the concentration of high-end diagnostic technology in the capital. However, many patients find that travelling to regional centres of excellence, like those led by Dr Manu Mathew and his team — provides access to identical or superior technology and consultant-led care at a more competitive price point.
Which Type of Laser Eye Surgery is Right for You?
There is no universal “best” vision correction surgery. The right choice depends on a multi-factorial clinical assessment including:
- Corneal Thickness: Measured in microns; determines if a flap can be safely made.
- Prescription: High degrees of myopia or hyperopia may be better suited to specific lasers.
- Lifestyle: Professional athletes or those in the police force may be steered toward surface treatments.
- Eye Health: Issues like chronic dry eye or large pupil size must be managed.
The gold standard of care in the UK is consultant-led care, where the surgeon who performs your procedure is also the one who assesses you and manages your aftercare.
Final Thoughts
Advancements in laser eye surgery in the UK have made the dream of clear vision more accessible than ever. Whether it is the rapid recovery of LASIK or the long-term structural benefits of LASEK and PRK, there is likely a solution for most prescriptions.
Making an informed decision starts with education, but it ends with a professional clinical evaluation. If you are considering moving away from glasses or contacts, we encourage you to book a consultation to discuss your options in a pressure-free, clinical environment.
