Are You Suitable for Laser Eye Surgery?

Laser eye surgery is a fast-evolving alternative to glasses. The procedure involves using lasers to create a very precise flap in the cornea in order operate on the eye’s delicate interior. Success rates are constantly increasing as technology advances and the medical profession accumulates a body of knowledge on the subject.

As a result, laser eye surgery is for many people becoming a very real alternative to wearing glasses or contact lenses, but not everyone is suitable for the procedure. Below is a brief guide to help you discover if you are suitable for laser eye surgery. However, it is advisable to consult an eye care professional before coming to a decision.


If your eyes are still changing, you may not be suitable for laser eye surgery. It is therefore commonly advised to wait until your eyesight has stabilised (i.e. less than 0.5D change in the preceding two to three years)

Whatever the condition of your eyes, the NHS recommends that you should not undertake laser eye surgery below the age of 21.


Luckily the majority of people who suffer from impaired vision are eligible for laser eye surgery. Different procedures exist to counteract the detrimental effects of long-sightedness, short-sightedness, astigmatism and presbyopia.

Although there are special procedures dedicated to extreme prescriptions, success rates are lower than those with only minor vision impairments. Your doctor should be able to advise you on the probability of success in your particular case.


Your eyes need to be healthy in order for them to be safely operated on. Any existing conditions such as glaucoma, severe keratoconus, or herpes eye infections should be treated before any laser eye surgery.

Likewise, other illnesses may affect your suitability. People who have diabetes or suffer from an impaired immune system are not generally advised to undergo laser eye surgery.

There are a whole host of external influences, such as the use of some prescription drugs, which could affect your suitability. Make sure to give your medical professional all the information they may need in order to assess your situation accurately.


Pregnant women are not generally advised to undergo laser eye surgery. Hormones released while pregnant or breastfeeding can cause tiny fluctuations in the eye, rendering the delicate procedure involved, impossible.

Treatment is not recommended in the months immediately after childbirth, as the prescription can vary and fluctuate.


Even those who suffer from cataracts, a condition characterised by the clouding over of the lens, can benefit from laser eye surgery. The procedure involves making a small incision in the cornea, removing the damaged lens and replacing it with a synthetic substitute.

Although it covers the main areas, this guide is by no means extensive. Do consult your eye care specialist for a professional opinion, or arrange a consultation with a laser eye surgery expert.
