The aim of LASIK eye surgery is to improve quality of life by improving unaided vision. In this regard, the results of LASIK are generally excellent. More than 96 per cent of people who undergo surgery no longer require glasses or contact lenses.
It’s important to understand that no surgeon can guarantee perfect vision. The degree of improvement in vision varies from person to person.
Those with higher degrees of refractive error have more chance of needing to wear glasses for some activities such as night driving. Those in the presbyopic age group (usually between 40-50 years of age) will eventually need glasses for reading and other activities where they cannot focus on close objects.
People who are most satisfied with the results of laser correction have realistic expectations of the outcome, and clearly understand the potential risks and side effects. Generally, patients most suited are over 18 years of age, and have had no change in their spectacle prescription for 1-2 years.
