What is LASIK eye surgery?

LASIK laser eye surgery is the most commonly performed treatment at OCL Vision. LASIK is an acronym that stands for Laser-Assisted In Situ Keratomileusis.

Your eyes see by allowing light to enter through the cornea (the front part of the eye) and focus on the retina. The information is then communicated to the brain via the optic nerve.

Most people with poor eyesight have eyeballs that are either too long or too short in relation to the size of the cornea. Eyeballs which are relatively long mean that images focus in front of the retina, making you short-sighted. Eyeballs that are relatively short mean that images focus behind the retina, making you long-sighted.

Laser eye surgery reshapes your corneas with precision accuracy so that light will focus directly on your retinas. The result is that you will be able to see clearly without the need for glasses or contact lenses.

We offer laser eye surgery from £3950 for both eyes. Don’t compromise on eye care! Your eyes are unique and we customise all of our treatments to give you the best vision possible. Our pricing is transparent, with no hidden extras. We offer a 0% interest credit payment plan over 6, 12 or 24 months to help spread the cost of this life-enhancing procedure.

What is the process of LASIK eye surgery?


We’ll take you through the process step by step and explain the potential complications to help you to weigh up the risks and benefits in order to make an informed decision regarding laser eye surgery.


LASIK eye surgery is completely painless and the whole procedure typically takes around 10-15 minutes from start to finish. Anaesthetic drops are used to completely numb the surface of each eye. A femtosecond laser creates an ultra-thin flap in the cornea, and the surgeon will gently reflect the flap so that the second laser (the excimer laser) can reshape the cornea. A state-of-the-art pupil tracking device ensures accuracy and safety. If the eye moves during surgery the laser will follow the eye or automatically stop if necessary. The surgeon will then reposition the flap before moving on to the other eye.


Some patients experience dryness of their eyes, reduced night vision, glare and infection after LASIK eye surgery. These symptoms are usually temporary.


If you are about to have or have just had LASIK eye surgery you’ll want to know how to look after your eyes immediately after surgery to get the best results from your investment. We will let you know what to do, for example avoiding rubbing your eyes, contact with water, staying away from dirt and dust and wearing sunglasses.

The majority of patients have fully recovered and can go about their usual day to day activities just 24-48 hours after surgery. There are certain things, such as swimming, that you’ll need to avoid for a little longer. Read more about exercise after laser eye surgery here.

What are the 5 steps of LASIK?

OCL Vision theatre technician Becky talks through the 5 steps of LASIK eye surgery. First the patient’s eyes are cleaned, then anaesthetic eye drops are applied. Next a laser is used to create a corneal flap followed by a second laser used to reshape the cornea. Finally, the flap is replaced. All done in about 5 minutes per eye!

What technology do we use for LASIK eye surgery?

Faster lasers are more accurate. As well as making laser eye surgery even safer, this also means that more eye tissue can be conserved. So, OCL Vision use the fastest lasers available, for all LASIK procedures. LASIK eye treatment is a totally bladeless, wavefront-optimised guided procedure that is carried out using the world’s fastest and most accurate laser combination:

  • The Swiss-engineered Ziemer Z-8 low energy Femtosecond Laser is used for flap creation.
  • The German-made Schwind Amaris 1050RS Excimer Laser is used to shape the cornea. This laser will remove 50% less tissue than most other lasers currently in use and does it in less than half the time.

How safe is LASIK eye surgery?

Millions of LASIK procedures have now been safely carried out worldwide. In fact, LASIK eye surgery is now the most common elective procedure for adults to undergo in the western world. The latest LASIK technology means that problems from surgery are very rare indeed. As with any operation, however, there is a small element of risk. The skill and training of the surgeon are therefore critical to ensure that things go smoothly.

Our world-class surgeons use the very best technology and are able to safely treat prescriptions and conditions that most other laser vision surgeons cannot.

Why choose LASIK eye surgery?

LASIK could save you money. Why not check out our vision correction calculator to find out how much you could save by giving up contacts and glasses?

LASIK gets results. Provided you have a common prescription with no other visual complications, your chances of 20/20 vision following LASIK are very high. There is now almost 20 years of research data showing that in the right hands LASIK is both safe and effective. In fact 100% of OCL Vision patients see 20/20 or better with both eyes.

LASIK offers patients satisfaction. If you’re worried about how you will feel following the procedure, this research is reassuring. It shows that LASIK has a much higher satisfaction rate than contact lenses.

LASIK can treat unusual prescriptions. If your prescription is very high or if you suffer from presbyopia, LASIK can offer a solution. For many patients, LASIK vision correction provides results they never thought possible. Astigmatism, a common condition caused by the shape of a person’s cornea, can also be corrected with laser eye surgery.


At OCL Vision we offer several types of laser eye surgery, including LASIK and LASEK. Over 90% of patients are suitable for LASIK, making it our most common type of laser surgery.

LASEK is an option for patients who have thinner corneas. This procedure doesn’t involve a flap being created, meaning that reshaping takes places on the surface and recovery time is a little longer. The risk of serious complications following surgery (less than 1 in 1000) is the same for both LASIK and LASEK.

At your consultation, your surgeon will discuss with you which option is likely to suit you best based on your eye health and personal preferences.



Laser blended vision

Laser blended vision is a unique and pioneering treatment for patients with presbyopia, who would otherwise need reading glasses. For this treatment, LASIK eye surgery is used to adjust each eye differently, so one eye will be used for distance and the other targeted for close-up viewing.The brain usually adapts to each eye, focusing at a different distance within six to eight weeks.


For patients with extremely high prescriptions, LASIK eye surgery can be part of a combined treatment known as bioptics. This technique corrects the majority of the refractive error with a refractive lens exchange or implantable contact lens. Following surgery, any small residual refractive error can be refined with advanced Z-LASIK.

Bioptics is a rare procedure that can only be carried out by highly-trained refractive surgeons, since it involves highly skilled surgery in more than one field. The consultants at OCL Vision possess experience in both lens implant surgery and laser eye surgery, making them the few surgeons offering this option in the UK.

The history of LASIK eye surgery

Laser eye surgery was first approved in 1995, but the procedure has developed considerably since then. The 1995 procedure was called Photorefractive keratectomy or PRK. During PRK, the outer surface of the cornea is removed and the laser works directly on the corneal tissue to change its shape and improve vision. PRK has longer recovery time and a higher risk of infection than other laser eye procedures. Despite this, PRK is still available and in some cases is the most suitable option. LASEK is a variation on PRK.

LASIK eye surgery has been available since 1999, overcoming the issues associated with earlier forms of laser eye surgery. Using lasers for both the incision under the cornea and the change to its curvature means that it’s easy to control, has predictable results, it’s relatively painless and comes with very short recovery time.
