LASIK Common Questions

What is the success rate of LASIK?
The goal of LASIK is to reduce your dependence on your glasses or contact lenses. At least 95% of LASIK procedures, performed on patients with a suitable prescription, result in you reaching the legal driving standard without glasses or contacts, 6/12 or better. Our goal is to try to achieve the best possible vision for you. It is important you understand that results may vary for many reasons and are influenced by your prescription and your corneal thickness. 75% of our patients achieve even better results: 6/6 (20/20) vision.

Following treatment 25% of patients may require glasses occasionally, usually only for detailed distance vision such as driving. Older patients will require reading glasses due to presbyopia which cannot be treated with LASIK.
Does LASIK hurt?
LASIK is a virtually painless procedure. Anaesthetic drops are used to numb the eye and although most patients claim there is no pain, some have mentioned that they can feel mild pressure or vibration. There is usually some temporary minor discomfort after the procedure, which is relieved by taking a nap and using the drops as prescribed.
Why is LASIK the most commonly performed laser treatment?
LASIK offers a number of benefits over other forms of laser vision correction because it is performed under a protective layer of corneal tissue. As a result of this and the latest laser technology available, there is less surface area to heal. This also means less risk of corneal haze and scarring, less postoperative discomfort and your vision will return more rapidly, often within a day or so. LASIK can also treat a higher range of vision errors.

Is LASIK safe?
Since 1988, more than 10 million excimer laser procedures have been performed worldwide. Laser vision correction is projected to become the most commonly performed surgical procedure in the world.

Although the vast majority of patients achieve outstanding results without complications, it should not be forgotten that LASIK is however a surgical procedure. As with all surgical procedures there are risks associated with treatment.

The most common risks include:

i.
Surgical complications relating to the flap. This may be because the flap is not perfect at the time of surgery in which case the laser treatment is best deferred for 3 months. The flap may also cause problems if it heals irregularly. Most flap complications can be corrected without compromising the visual outcome.

ii.
LASIK is associated with dryness of the eyes and some patients require tear drops for a few months after treatment. It is rare for tear supplements to be required long term.

iii.
Glare and halos around lights are seen by some patients post-operatively. They do not usually interfere with driving and in most cases resolve within the first 6 months.

iv.
Under or over correction occurs when a patient’s individual healing response varies from the average for their age and sex. This is more likely to occur in the correction of higher degrees of short or long sight.

v.
Reduction of vision, even with glasses or contact lenses, can result following all forms of laser surgery. This may be due to inflammation or infection of the cornea after treatment, or because of irregular healing or scarring of the cornea. Severe visual loss is rare but in extreme cases patients have required corneal transplants following treatment.

Why should I choose Grange Eye Consultants to perform my LASIK?
Laser vision correction, although quick and virtually painless is nevertheless a form of eye surgery. At Grange Eye Consultants your eyes will be treated by a locally based surgeon who is an accredited Consultant Ophthalmic Surgeon working in the NHS and independently.

Our consultants have an outstanding track record of results and long-term reputation to maintain: You can be assured that you will receive the most dedicated of care, as a private outpatient, with all the benefits of a high quality private hospital.

Am I a suitable candidate for LASIK?
Generally speaking, the ideal LASIK candidate is over 21 years of age and has healthy eyes and normal corneas with no significant change in their spectacle prescription in the last 2 to 3 years. Certain medical conditions make people unsuitable candidates. Pregnant or breastfeeding women should allow several months after giving birth or ceasing feeding before having treatment. Some patients who are not suitable for LASIK are suitable for LASEK.

Would I be better off having a Wavefront guided treatment?
Not everyone is suitable for a Wavefront treatment and we will not perform a Wavefront treatment unless we feel there will be definite benefits for you over standard LASIK. If you have a complex profile due to your pupil size, a large refractive error, considerable higher order aberrations, a need for re-treatment or concerns over night vision then you may well achieve significantly better results with a CustomVue wavefront guided treatment.

Should I have both eyes treated at the same time?
Many people find it more convenient to have both eyes treated together but there are advantages and disadvantages to this which will be fully explained at your assessment. Patients who do opt for unilateral surgery need to wait until one eye has fully healed before undergoing surgery on the 2nd eye and in these cases we recommend at least 1 month between treatments. Unilateral treatment is best suited for patients with low refractive errors who are able to tolerate uncorrected vision in one eye or those who can wear a soft contact lens in the untreated eye. Patients with moderate or high refractive errors who are unable to wear lenses, often find the interval between treatment sessions difficult to tolerate.

Following the consultation with your surgeon you can make an individual decision on which option is best for you.

I have been told I am unsuitable for laser vision correction. Are there any other refractive surgery procedures?
Yes. Although laser vision correction is the most widely publicised, there are other refractive techniques that have been successfully performed for years by Consultant Ophthalmic Surgeons in the UK and internationally. As these procedures involve surgery inside the eye (intra-ocular surgery), they are more complex. At Grange Eye Consultants we are trained and skilled in PRELEX, Refractive Lens Exchange, Implantable Contact Lenses (ICLs), LASEK and LASIK.

To find out which procedure would be best suited to your individual eyes and lifestyle we offer a full initial examination and assessment with a Consultant Ophthalmic Surgeon. You will be given advice on the treatment options that can be recommended for you together with information about the benefits and the potential risks and complications of those procedures.

How much will it cost?
Our Practice Managers will be able to offer guidance on the cost of an initial consultation and the various treatment options available.

How can I pay for my LASIK or Wavefront procedure?
Grange Eye Consultants are able to arrange a finance plan with credit facilities to fund the cost of treatment. We also accept cash, cheque, Switch, Visa and Mastercard or any combination of these.
