No. The treatment itself is completely painless. Large amounts of anaesthetic drops are used which completely numb the eye. You might feel a bit of pressure at the very beginning when the Intralase laser is used to create the front flap. After the procedure some patients describe a gritty sensation like a lash in their eye. Some feel a bit of stinging and this lasts for a few hours. For this reason we ask patients to have a nap for about 4 hours after the procedure. Paracetamol or Advil is the most you will need to manage the discomfort.

The procedure has been in use for over 20 years and is approved by the USA’s stringent Food and Drug Administration (FDA). The procedure is also approved by the UK’s National Institute of Clinical Excellence (NICE). The outcomes and safety of the procedure is highly dependent on the Surgeon, the centre and its processes and environment as well as technology.

You will need to be seen the next day or a few days after the initial procedure. You will then be seen at 1 month and again at 6 months for a final visit. Sometimes patients are seen at 3 months if there are concerns about regression or if there is a possibility that an enhancement treatment may be needed. More frequent appointments may be scheduled if needed. Our surgeons at Centre for Sight are available to see you whenever necessary and a helpline is available 24/7.

Mascara should be avoided for 4 weeks.
All other make-up can be used 2 days following surgery.

You may return to all spor ting activity after TWO weeks For contact sports, you are advised to use protective eye glasses. Polycarbonate sports glasses are recommended.

After 4 weeks

Usually one or two days. You may return to work as soon as you are comfortable. Make sure you are able to take your eye drops regularly as instructed.

This is highly variable. Some patients obtain good vision within 24 hours and others may take a little longer. Much depends on each individual’s response to healing.

Firstly, it’s important to avoid dusty or smoky atmospheres for the first two weeks after your surgery. Here are some common questions about what you can and can’t do after surgery:

• Can I shower after laser eye surgery? You can shower the next day but you must make sure your eyes are closed.
• How long after laser surgery can I drive? When you are comfortable with your new vision, and if it meets the level required to meet the driving standard.
• How soon after surgery can I go back to work? The next day if you are comfortable. Make sure you are able to take your eye drops regularly as instructed.
• Can I use a computer after laser eye surgery? The next day but be sure to take breaks every 20 minutes and close your eyes for 20 seconds. Make a conscious effort to blink more often.
• When can I exercise at a moderate pace? After one week.
• What about exercising at an intense level? Please wait for two weeks and use a headband to absorb any perspiration to prevent this from entering your eyes.
• When can I return to playing sports? You may return to all sporting activity after TWO weeks. For contact sports, you are advised to use protective eyeglasses. Polycarbonate sports glasses are recommended.
• Can I go swimming after laser eye surgery? After three weeks but with goggles, four weeks without.
• When can I go Scuba Diving? After 4 weeks.
• When can I wear eye make up again? Please do not wear mascara or eyeliner for TWO weeks. For all other make-up, please wait for two days. Consider having your eyelashes tinted before surgery. When removing eye make-up, use your usual make-up remover gently and finish it by using preservative-free eye-lid cleansing lotion.
• When may I return to activities such as housework, shopping, and gardening? There are no restrictions, and you may return to these activities the following day. You must keep away from smoky and dusty environments and do not forget to wash your hands before using your eye drops.

It usually takes less than 15 minutes for both eyes. However, in order to prepare you for the procedure and ensure recovery you will be at the centre for 2-3 hours

It’s impossible to blink during the surgery as we use a special clip that gently holds your eyelid open.

The main danger or disadvantage is that, as with any technically complex eye surgery, rare problems with vision can occur. This is usually at the stage when the surgeon creates the flap, which can affect your permanent vision. The risk is greatly reduced by using femtosecond laser technology in the hands of an experienced surgeon and reputable provider like Centre for Sight.

Centre for Sight has always had the very highest standards in hospital safety and procedures and Intralase decreases the risk of infection further. IntraLASIK also uses one-time use disposable instruments, further improving this level of safety.

Laser eye surgery with appropriate patient selection and treatment provides excellent outcomes. With current technology, serious problems are extremely rare. There are however some side effects that you must be aware of:

Dry eye: Laser eye surgery affects the nerve receptors that sense dry eye and as a result tear production can be temporarily reduced. To compensate for this, artificial tears (provided) are required for at least 6 to 12 weeks whether or not there are dry eye symptoms. Consider there may not be symptoms as the nerve endings will not have recovered. As nerve endings and receptors recover, dry eye improves. Patients at risk of severe dry eye are identified at consultation and either treated for dry eye beforehand or declined for laser surgery.

Over-correction, under-correction, and regression: It is possible but very unusual for the eye to be overcorrected, under corrected or slip back (regression) slightly over the first 6 weeks. Much depends on how the eye responds to surgery, how it heals and whether or not artificial tears are used. Dry eye (symptomatic or not) can result in regression. If this is significant and affects the visual outcome, an enhancement will be performed to correct this at 3 months as long as the eyes are stable. To reassure you, this occurs infrequently at Centre for Sight with less than 1% of our patients requiring an enhancement and there is no further charge for correction within the first year of treatment.

Night vision disturbances: It is normal to experience some initial disturbance after the procedure which rapidly decreases over a period of days to two weeks. This occurs from mild swelling of the cornea and subsequent light scatter. Long term disturbances are rare with the correct treatment choice being tailor-made for each eye (i.e. with Aspheric and Wavefront Aspheric treatments).

Most health insurance companies do not cover laser eye surgery where the purposes for treatment are elective vision correction.

At Centre for Sight, our prices are always transparent with no hidden extras. We also have finance options to make your surgery more affordable. To learn more, see our page on pricing.

Although every patient is different, the vast majority of InterLASIK patients achieve legal driving vision or better by the very next day. In a very small number of patient’s vision will take longer to recover, possibly up to 10 days.

Before your consultation: how to prepare 

If you are a contact lens wearer, we ask you to stop wearing your contacts for at least one week if they’re soft lenses, and four weeks if they’re hard/gas permeable lenses. This helps us to accurately assess your eye and the degree of correction required.

During the evaluation, we shall test your vision with and without your glasses. You will also be checked on a machine called an autorefractor. Other tests include:

• Contrast sensitivity
• Corneal topography (the shape and curvature of your cornea) – using 4 different methods
• Corneal thickness
• Mechanical strength of the cornea
• Eye pressures

We’ll also measure the way a wavefront of light passes through the cornea and the crystalline lens using a method known as aberrometry.

At the same time we capture details of your iris for our Advanced Controlled Eye Tracker, a tool that helps track the eye and provide accurate laser spot delivery during surgery, even with finest and fastest of eye movements.

In addition, we shall also evaluate you for dry eye. Lastly, we use special drops that dilate your pupils and paralyse your internal muscles and this allows us to both check the true power of the eye when in a relaxed state and examine the retina at the back of the eye to exclude any potential issues.

Once your surgeon has finished the assessment, they will recommend the best treatment option for you (if any) and talk you through the benefits, alternatives and risks as well as the post-operative and recovery phase.

There’s a good chance we’ll be able to suggest other treatments based on your specific eye issue. Your surgeon will talk you through the options during your consultation.

To find out whether you’re a suitable candidate you can use the Am I Suitable questionnaire and our staff will respond with some specific treatment options. Although each case is assessed individually, generally speaking you will meet the criteria for laser eye surgery if you can say yes to the following:

• You are over 18 years old (if required for your career) – otherwise 21 and above
• You are Short-sighted, Far-sighted or have Astigmatism
• Your vision has remained the same over the past 12 months (less than 0.50D change in the last year)
• You have a good eye health and no autoimmune diseases
• You are not pregnant or nursing

Lastly, you’ll also need to have an extensive 2-3 hour period of investigation followed by a consultation with a surgeon to see whether your eyes are suitable for surgery. To save time, this may be divided into preliminary screening tests and if suitable you will see the surgeon for a lengthier visit at a later date.

Safety is paramount
At Centre for Sight, we are very selective about those who are eligible. Safety is our number one priority, and we make our decisions based on scientific evidence, delaying (and first treating where appropriate) or declining those who might be at increased risk.
