What it is
Refractive procedures such as LASIK reshape the cornea to reduce dependence on spectacles or contact lenses. Not everyone is a suitable candidate: corneal thickness, corneal shape, tear film, retinal health, age and a stable spectacle power all have to be assessed first. Outcomes vary between individuals and cannot be promised in advance.
When you might need it
- You are considering reducing your dependence on spectacles or lenses
- Your spectacle power has been stable for at least a year
- Contact lenses are difficult for you to tolerate
- You want to know whether you are a candidate before deciding anything
What happens during your visit
A detailed refractive workup includes corneal mapping (topography), corneal thickness measurement, dilated refraction, tear film assessment and a retinal check. The doctor then explains whether you are suitable, which procedure suits your eyes, and the realistic range of outcomes and the risks involved. If you are not a suitable candidate, you are told so plainly.
Aftercare
If you proceed, drops and a review schedule are given, and eye rubbing, dust and swimming are restricted for the initial period. Some people still need spectacles for certain tasks, including reading as they get older.
