Vision Surgery Risks - Focus Clinic

Vision Surgery Risks

Approximately 7% of all shortsighted adults in the UK have now had their vision corrected with an excimer laser. More than 100,000 LASIK procedures are carried out each year in the UK alone.

Many of the remaining 93% of the population who have myopia (shortsight) have heard about the benefits, but have yet to make the decision to go-ahead and receive treatment. We know that the majority of these patients are interested in removing the need to wear glasses or contact lenses. The number one reason for hesitation is the perceived risks and the worries that ‘something’ may go wrong.

What is the most important factor? Patient selection.

The effect of technology

Stories of patients having a complication, for example halos or glare at night, from earlier technologies during the 1990s still affect perceptions today. The public’s perception of modern surgery is about a decade behind reality. Research has shown that with good patient selection risks are in fact much lower than people think.

The reality of modern surgery

At Focus in London we use surgical skill and technology sufficiently advanced that 100% of shortsighted patients with all common prescriptions now achieve 20/20 vision. In fact, 99.7% of our patients can see even better than 20/20 following correction. The majority of  patients now achieve “supervision” of 20/12. This extremely high level of sight is almost twice as good as 20/20, and equates to being able to read a car number plate at more than 200 feet.

It is this “perfect score” of 100% of all common shortsighted prescription patients seeing 20/20 that reassures many patients to choose Focus. It helps remove the feeling of “what if” when having their vision corrected, removing worries about risks or complications of treatment.

The Lifetime Care Guarantee offered by Focus is also a great reassurance. Anyone treated for their shortsight at our clinic in order to improve distance vision, and who finds that they need distance glasses once again in the future, if suitable can have a free enhancement at any point.

Does the benefit wear off?

It is a common myth that the results of surgery where off over time. In fact, for properly selected patients, laser correction is a permanent treatment. It is possible however that someone’s myopia may get worse and, despite having a very stable result from the excimer ablation, the patient finds that the distance vision has become somewhat blurred once again.


The Lifetime Care Guarantee offered by Focus will still provide a free enhancement to boost the distance vision of such a patient who has had worsening of their myopia, even though the initial treatment was fully successful and permanent. This commitment to the patient’s vision and well-being is part of what makes Focus stand out from the crowd.
