What is LEX?

Femtosecond Laser Lenticular Extraction (LEX) is a modern laser eye surgery that corrects vision by removing a precisely shaped piece of tissue (called a lenticule) from within the cornea. Using a femtosecond laser, the lenticule is created entirely inside the cornea and removed through a very small incision.

By altering the shape of the cornea from within, LEX allows light to focus correctly on the retina, improving vision without the need for glasses or contact lenses. Unlike LASIK, LEX does not require a corneal flap, making it an attractive option for patients seeking a minimally invasive approach to vision correction.

Types of Laser Eye Surgery

LASIK (Laser-Assisted In-Situ Keratomileusis)

LASIK is the most commonly performed type of laser eye surgery. It uses two advanced lasers, one to create a precise, ultra-thin layer on the surface of the cornea, and another to gently reshape the tissue underneath to correct vision. The treatment is quick, comfortable, and highly accurate, with most patients experiencing clear vision within 24 hours.

LASEK / PRK (Surface Laser Treatment)

LASEK and PRK are surface laser techniques where the outer layer of the cornea is carefully moved aside so the laser can reshape the surface underneath. These methods are often recommended for people with thinner or irregular corneas, or for those involved in contact sports or high-impact activities. Recovery takes a little longer than LASIK, but visual results are equally good once the eye has healed.

Supracor LASIK (for Reading Vision / Presbyopia)

Supracor LASIK is a customised laser treatment designed to correct both distance and near vision, reducing the need for reading glasses. It reshapes the cornea with a unique profile that provides a wider range of focus. This option is often ideal for people aged 40 and above who want greater visual freedom without relying on bifocals or varifocals.

LEX:

A flap-free, keyhole laser procedure reshaping the cornea from within, ideal for suitable myopic patients or those with an astigmatism.

Who is Suitable for LEX?

LEX may be suitable if you:

• Are short-sighted (myopic), with or without astigmatism
• Have healthy eyes and stable vision
• Prefer a flap-free laser eye surgery option
• Have corneal measurements suitable for lenticule extraction
• Lead an active lifestyle or work in environments where flap-based surgery may be less ideal

Suitability is confirmed through comprehensive diagnostic testing, including corneal imaging and ocular health assessment. Your consultant will recommend LEX only if it is the safest and most effective option for your eyes.

What Are the Benefits and Risks of LEX?

Your surgeon will speak with you about the benefits and risks involved before your procedure.

Benefits (vary by procedure):	Risks/side effects (not exhaustive):
Flap-free, minimally invasive laser correction	Temporary dryness or visual fluctuations during healing
Preserves corneal biomechanics	Not suitable for all prescriptions or eye shapes
Reduced dry-eye symptoms in suitable patients	Enhancements, while uncommon, may occasionally be required
Quick return to daily activities
Excellent visual outcomes for myopia and astigmatism

Patient Journey

Enquiry

Start by filling in our online form or contacting our friendly enquiry team. We’ll answer your initial questions and guide you through the first steps toward clearer vision.

Diagnostics

Before any treatment is planned, we carry out a comprehensive series of diagnostic tests using up to 16 of our machines. These detailed scans measure your prescription, corneal thickness and shape, tear film, and overall eye health, ensuring the most accurate and personalised treatment plan.

Consultation

You will meet your consultant ophthalmic surgeon, who will discuss your test results in detail, explain your treatment options (LEX, LASIK, LASEK/PRK, or Supracor), and confirm your suitability. All benefits, risks, and alternatives will be clearly explained before you decide to proceed.

Treatment

Your LEX procedure is quick and comfortable, typically taking only a few minutes per eye. Using advanced femtosecond laser technology, your surgeon reshapes the cornea to correct your vision with exceptional accuracy. Most patients notice clearer vision within 24 hours.

Aftercare

Following surgery, you will have access to a 24-hour helpline and structured follow-up appointments included for one year. Our dedicated team monitors your healing and visual outcome closely, ensuring you achieve the best possible results.
