LASIK involves cutting a flap in the cornea, lifting the flap and applying the laser treatment underneath, then replacing the flap and allowing the eye to heal.
LASEK or Advanced Surface Ablation is a less invasive method of laser treatment in which the epithelial cells (surface layer) of the cornea are moved gently to one side, the laser is applied directly to the exposed corneal surface and then the epithelial cells are replaced to form a protective layer whilst the cornea heals.
Who needs it and why?
Patients with a low-to-moderate degree of short-sight, long-sight or astigmatism who want a permanent alternative to spectacles or contact lens. However excimer laser treatment will not correct presbyopia, (an age-related change in vision that usually makes it difficult to focus and requires reading glasses from the mid / late forties onwards).
How long does the treatment / surgery take?
Approximately 30 minutes for both eyes.
Is a general or local anaesthetic required?
Topical - Anaesthetic eye drops are used for this procedure.
Is a stay in hospital required?
No - Outpatient in theatre.
What are the risks and side effects of treatment?
Potential risks and complications include infection, under or over-correction, night vision problems, corneal haze, corneal dryness, corneal ectasia (weakening of the cornea). All of these would be fully explained at an initial outpatient consultation to consider suitability for treatment.
