What is it?
Myopia, hyperopia and astigmatism are refractive errors in which light is not focused precisely on the retina. Glasses and contact lenses are common corrections; for some people laser or implantable lens procedures may be options.
The suitability assessment examines the stability of your prescription, corneal thickness and surface map, tear film and the overall health of the eye in detail. If you wear contact lenses, you may be asked to stop for a period before the measurements.
The measurements show whether each eye is suitable for different methods; in some cases continuing with glasses or lenses may be more appropriate. Outcomes and expectations vary between people, and the path is decided with your doctor after the examination.
Who is it assessed for?
- Those aged eighteen or over whose prescription has been stable in recent years
- Those who find contact lenses difficult
- Those curious about alternatives to glasses because of work or sport
- Those previously told they were unsuitable for laser and seeking reassessment

Questions
When should I stop wearing contact lenses before laser assessment?
It depends on the lens type. Before your appointment you are told which lenses to stop and for how long.
Is everyone suitable for laser treatment?
No. Corneal structure, prescription level, tear film and some general health conditions affect suitability. The decision is made after the measurements.
How long does the assessment take?
Because of the measurements and pupil dilation, it may take longer than other examinations. Plan your day accordingly.
