1.1 Current evidence on laser in situ keratomileusis for the treatment of refractive errors suggests that it is efficacious in selected patients with mild or moderate myopia. Evidence is weaker for its efficacy in patients with severe myopia and hyperopia.
1.2 There are concerns about the procedures safety in the long term, and current evidence does not appear adequate to support its use without special arrangements for consent and for audit or research.
1.3 Clinicians wishing to undertake laser in situ keratomileusis for the treatment of refractive errors should take the following actions: - Ensure that patients fully understand the specific risks associated with the procedure and provide them with clear written information. Use of the Institute's Information for the Public is recommended. -Audit and review clinical outcomes of all patients having laser in situ keratomileusis for the treatment of refractive errors.
1.4 Clinicians should have adequate training before performing the technique. The Royal College of Ophthalmologists has produced standards for laser refractive surgery (http://www.rcophth.ac.uk/about/aboutcollegedocs/RefractiveSurgeryStandardsMay2004.pdf).
1.5 Further research will be useful and clinicians are encouraged to collect longer-term follow-up data.
1.6 The procedure has been referred to the Review Body for Interventional Procedures for systematic review.
