You will have to be seen by a consultants and have your eyes examined before it can be established for certain whether you are a suitable candidate for refractive surgery. However, if you fit all the following criteria you may well be suitable for corrective surgery:
- You must be over 21
- In general good health
- Have had stable prescription for at least 12 months
- Both eyes must have good vision
- You should have a prescription within the recommended safe range for the procedure. For LASIK this is -1.00 to -10.00 (short sight) or +1.00 to +6.00 (long sight) including any astigmatism. Higher refractive errors can be corrected by lens implantation. Ask your optometrist if you are not sure how to interpret your prescription
You may not be suitable if:
- You are pregnant
- You have had a previous Herpes viral infection of the cornea
- You are taking any drugs which interfere with the healing response such as chemotherapy
- One or both eyes has a significant ocular abnormality or keratoconus (conical cornea)
- You have severe dry eye disease
- You have worn contact lenses within 2 weeks (soft lenses), 4 weeks (gas permeable hard lenses), or 6 weeks (conventional hard lenses) of the pre-operative assessment - contact lens wear can cause temporary changes in your corneal shape making accurate assessment difficult
- You have certain medical conditions, such as diabetes mellitus, SLE, rheumatoid arthritis, connective tissue disorder or other auto-immune disease
