Most people’s glasses prescription can be easily corrected using laser refractive surgery to provide good unaided distance vision. This is achieved by changing the shape of the cornea using an excimer laser to either make it flatter if you are short-sighted or steeper if you are long-sighted. The amount of change in shape needed to correct vision is tiny, often less than 50 microns. Laser refractive surgery has been performed since the mid 1990’s and is one of the most common ophthalmic procedures in the UK.
LASIK is a quick procedure with a short recovery time. It uses lasers to reshape the cornea and is usually carried out under local anaesthetic. There might be some mild discomfort for a few hours following the procedure but most patients are able to see well enough to work and drive a car the next day.
What if I am unsuitable for LASIK?
If during your consultation your scans suggest you have a relatively thin cornea, or an unstable cornea shape, a surface laser treatment called LASEK, would normally be recommended.
The most accurate way to confirm your suitability is to book a consultation with our ophthalmic consultant. A full consultation will always be required before you can choose to undergo surgery.
