Book yourself a FREE CONSULTATION for life-changing Laser Eye Surgery today.

Long-sighted, short-sighted and astigmatism… however HIGH or LOW your prescription is, for the sake of clarity and transparency we use fixed pricing and will not change our price after your consultation – and that includes a comprehensive eye examination.

LASIK stands for laser-assisted in situ keratomileusis and is the most commonly performed type of laser vision correction in the world. LASIK eye surgery is proven to be safe and effective. Advanced Wavefront LASIK is completely blade-free and has a very quick recovery time, hence is now the first choice for vision correction.

There are two parts to the blade-free LASIK procedure:

A micro-thin flap is created in the cornea using a precision laser
A cool beam excimer laser is then used to reshape the cornea to correct the prescription.

With the introduction of bladeless LASIK in the 90’s, the appeal of LASIK treatments has improved considerably. Previously, normal LASIK procedures relied on the use of a microkeratome, a mechanical device which itself uses a blade in making the LASIK flap. 

LASIK eye surgery working

However, Advanced Wavefront LASIK differs by instead using a femtosecond laser. With this laser, we can produce a corneal flap that is significantly cleaner, thinner and more precise than that possible with standard LASIK surgery. For the patient, the resulting benefits and safety are immense.

Advanced Wavefront LASIK is able to treat a wide variety of prescriptions; long sight, short sight and astigmatism. Precision Vision’s expertise in laser vision correction is world renowned and has a reputation of successfully treating higher and more complex prescriptions, often treating those found unsuitable by other clinics.

Dr. CT Pillai was one of the first surgeons in the UK to perform bilateral (both eyes treated on the same day) LASIK treatment.


Advanced Wavefront Lasik is the most popular form of vision correction treatment and is able to treat a wide variety of prescriptions, long sightedness, short sightedness and astigmatism, and all within the space of a few minutes.

To be potentially suitable you must be:

Aged over the age of 18
Within the following prescription range: Between -9 DS (short sighted) and +5 DS (long sighted), with up to -5 DC (astigmatism)
Have a stable prescription

With the best international surgical team in the UK, our combined expertise in laser and non-laser treatments is without precedent. We take great pride in having the skills to help even those who have been turned down by other clinics. So book a consultation now to learn how Precision Vision can perfect your sight and improve your quality of life today.


Although we are passionate about correcting the sight of all those we possibly can at our LASIK eye surgery London clinic, we neither provide experimental treatments nor operate on those who suffer from conditions that prevent safe and ethical treatment.

Common reasons patients are found unsuitable for LASIK treatment include:

Age: patients younger than 18 are ineligible.
Pregnancy or breastfeeding: Hormonal changes experienced during pregnancy and breastfeeding can temporarily affect the refractive errors of the individual
Thin corneas
Exceptionally large pupils
Unstable prescription: patients whose prescriptions have changed significantly in the past year should wait until their vision stabilises
Certain medications: You would be ruled out for LASIK surgery at our London clinic if you are taking immunosuppressant drugs.
Specific health conditions: these include autoimmune diseases
Previous instance of serious eye trauma or retinal detachment.


About Benefits Treatment Process


Laser eye surgery involves reshaping the cornea at the front of the eye to correct visual defects and imperfections like short sight, long sight and astigmatism. To correct short sight, the cornea is flattened and to correct long sight, the cornea is curved.

Advanced Wavefront LASIK is completely blade-free unlike traditional methods, and consequently has a quick recovery time. The procedure is carried out using two extremely precise types of lasers. A micro-thin flap is created on the cornea using the highly specific Intralase laser and an excimer laser is then used to reshape the cornea to correct the prescription.

If you need LASIK in Essex, Hertfordshire or any other area just outside London, rest assured that our Harley Street clinic is easy to reach from where you live.

So, just how was LASIK invented? On the right is a must-watch inspirational video on the development of the LASIK procedure. 

It also compares LASIK to other lesser procedures available at the time, which took months to correct vision. Rangaswamy Srinivasan, the inventor of the LASIK procedure explains the safety and high degree of precision offered by Laser Eye Surgery.


Traditionally Laser eye surgery was carried out using a blade to create the precision flap. Here at Precisoin Vision we use a blade-free technique called Lasik, which creates the corneal flap.

As a result, patients of our LASIK surgery London services can enjoy the following benefits:

Sharp and clear vision
Safety – with fewer flap complications
Computer controlled precision providing superb accuracy
Proven faster visual recovery
Enhanced flap stability – three times more compared with LASEK
Enhanced flap healing – increased flap adhesion post-operatively
Reduced dry eye symptoms
No heat is produced and no damage to the surrounding corneal tissue
Lasik treatment was approved by the FDA in 1999

Due to the treatment’s use of bladeless technology, patients don’t need to fret about potentially suffering complications resulting from a manual blade’s creation of the flap. This issue could arise with the previous, traditional form of LASIK treatment.

Patients can anticipate achieving vision of 20/20 clarity or better. Meanwhile, compared to the more basic traditional type of LASIK surgery, Advanced Wavefront LASIK treatment is safer for the patient both in the short and long term.

We are leading providers in LASIK eye surgery, not just because of our state of the art technology, but more importantly due to Dr. CT Pillai, Precision Vision’s Medical Director who is a highly skilled corneal specialist and is extremely sought after in the field of vision correction. You will be in the hands of an expert pioneering surgeon who has over 30 years’ of experience in the field of refractive surgery. Having an experienced surgeon carry out your laser procedure is paramount in ensuring you are getting the very best quality of vision, and in the safest manner possible.

For these reasons and many more, Precision Vision is increasingly the eye clinic choice for vision correction for not only people seeking LASIK from Essex, Hertfordshire and other England counties, but also patients across the globe.

Treatment Process

When arriving at our LASIK London clinic on the day of surgery our friendly and experienced clinical team will guide you through every step of the way. The treatment is painless and only takes 20 minutes for both eyes. We only carry out blade-free and needle-free treatments at Precision Vision.

The Lasik eye surgery procedure is as follows:

Anaesthetic drops are then applied to numb the eyes. You will be awake and comfortable throughout the procedure.
The consultant will then apply an eye lid guard which is used to prevent blinking.
The corneal flap is then created, using the blade-free FS laser (LASIK)
The excimer laser uses your personalised treatment plan to reshape the corneal tissue to correct your prescription.
Throughout the procedure, the Advanced Control Eye-tracking (ACE) system guides the laser during the treatment by following and mirroring the movement of your eye.
A protective soft contact lens is placed in each eye.
Your specialist nurse will go through any precautions and medications that are needed to aid recovery.

Advanced Wavefront Technology

The Aberrometer meticulously measures the prescription and imperfections (aberrations) of the eye. It accomplishes this by directing a beam along 9000 points of the cornea to the retina and calculates the required refractive errors at these precise locations. This information generates a refractive and aberrations profile for each pupil.

The Aberrometer then employs the Zernike algorithm to mathematically reconstruct the wavefront. Since the Aberrometer measures total wavefront aberrations and mathematically represents them up to the 5th order Zernike terms, it is not limited to just sphere and cylinder (as used for glasses and contact lens prescriptions). This data, combined with the numerous tests conducted during your consultation, is utilised to formulate a truly personalised treatment plan.

7 Dimensional Eye Tracking System

During the consultation, a comprehensive scan is conducted to map the entire iris of each eye. Just as fingerprints are unique, this mapping generates a distinct digital identification for each eye. This iris map serves as the basis for the operation of the multi-dimensional eye tracker.

Throughout the procedure, the Advanced Control Eye-tracking (ACE) system is utilised. This cutting-edge 7-dimensional eye tracker guides the laser during treatment by accurately tracking and mirroring the eye’s movements. If excessive movement is detected, the laser automatically shuts off, ensuring precision and safety during the procedure.

Before commencing LASIK treatment in London, the ACE system must first identify the unique ID associated with the eye undergoing treatment. This crucial step ensures that treatment profiles are always correctly linked to the respective patient and eye.

Key features of the 7 Dimensional eye tracking system include:

Iris Recognition Technology: Ensures precise placement of personalised laser treatment by accurately identifying the patient's eye.
Comprehensive Eye Tracking: Tracks all eye movements across 7 dimensions (XYZ, intraoperative rotations, and static rotations) using iris recognition technology.
High Sampling Rate: Captures images of the eye at a rapid rate of 1,750 times per second (1750Hz), allowing for real-time monitoring and adjustment.
Ultra-Fast Response Time: With a response time of 2ms, the system ensures that no laser pulses are ever misplaced, maintaining accuracy and safety.
Adaptive Tracking: Capable of following even the most sudden or subtle eye movements, ensuring precise delivery of laser treatment throughout the procedure.

Advanced Wavefront Lasik Vs SMILE

SMILE laser procedure is new laser technique where the surgeon uses a femtosecond laser to create a small, lens-shaped bit of tissue within the cornea. Then, with the same laser, a small arc-shaped incision is made in the surface of the cornea, and the surgeon extracts the lenticule through this incision and discards it. It is said to produce similar results as Lasik, however as it was only FDA approved in September 2016, it’s long term effects are not yet fully known.
