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
There are several types of laser eye surgery, each designed to suit different eyes, prescriptions and lifestyles. All laser vision correction procedures use an excimer laser to precisely remove microscopic amounts of corneal tissue, reshaping the eye so light focuses correctly on the retina and correcting refractive errors such as short-sight (myopia), long-sight (hyperopia) and astigmatism.
1
LASIK is the most commonly performed form of laser eye surgery. It involves creating a thin flap on the surface of the cornea before the excimer laser reshapes the underlying tissue. The flap is then repositioned to aid healing. LASIK is known for its accuracy, comfort and rapid visual recovery, with many patients achieving clear vision within 24 hours.
2
LASEK and PRK are surface-based laser treatments that reshape the cornea without creating a flap. Instead, the outer surface layer is gently moved aside or removed so the laser can correct the cornea directly. These procedures are often recommended for people with thinner or irregular corneas, or those with active lifestyles or contact sports. Recovery takes longer than LASIK, but long-term visual results are equally effective.
3
Supracor LASIK is a customised laser treatment designed to correct near, intermediate and distance vision, reducing reliance on reading glasses. It uses a specialised multifocal laser profile to extend the eye’s range of focus. Supracor is often suitable for people aged 40 and over who are experiencing presbyopia and want greater visual freedom without bifocals or varifocals.

A flap-free, keyhole laser procedure reshaping the cornea from within, ideal for suitable myopic patients.

Am I suitable for LEX?
Laser eye surgery can be life-changing for many people, but it isn’t right for everyone and determining suitability starts with a thorough, consultant-led assessment of your eyes.
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.
Not Sure If You're Eligible?
Schedule a comprehensive eye examination to determine your candidacy for LEX laser eye surgery.

Very professional and thorough service. The team really look after you. Particular shout out to Adora who was lovely and really made me feel relaxed throughout the whole process. Mr Daya is very obviously a master of his profession and would recommend him to anyone wanting Laser eye surgery. My vision is perfect!

Alexa Rose
I am free of glasses!!!!!! Thanks to Dr Daya & his Team. I feel great following PRK surgery. The whole procedure was seamless & quick. I was in a lot of discomfort after the procure for a few days (which is fairly normal). The aftercare was spectacular, fast and well put together!

My experience was great. Dr Daya is very talented and experienced eye surgeon. After LASIK I can see better then I saw when I was in glasses ( I was wearing contact lenses and glasses from the age of 10) Almost a year later everyday I wake up and think how amazingly my life has changed for the best – now I can see!
My life has definitely transformed. Thank you.

Absolutely life changing! I was only 20 when I got this done but having had a stable prescription I knew the time was right. Everyone is so welcoming from the moment you step in. I had a few options but Mr Daya directed me in the right way on which procedure suited me. Me being me I was nervous and they reassured me by giving me a lady’s number who had had the same procedure so I got to have a chat with her about all my worry’s. On the day it’s so straight forward and quick and within hours I could see better. Fast forward over a year I have better than 20:20 vision after previously being -8 my whole life, it is hands down the best thing I have ever done I wouldn’t second think getting it done, thank you so so much.
