It depends on:
- the size,
- location,
- depth of the scar and
- whether/how much associated corneal thinning there is.
In general, some form of laser refractive surgery (LASIK or PRK) can be considered if the best vision with spectacles is normal (6/6) and the scar is not in the centre of the cornea.
If the scar is small, e.g. <1mm, superficial and in the far corneal periphery, LASIK could be an option.
For some other types of scars, PRK may be advisable if the scar is likely to interfere with flap creation during the LASIK procedure.
So is it safe to do LASIK or PRK with a corneal scar? It really depends.
Hence, do consult with an experienced refractive surgeon. He/She will examine your eye carefully, perform the necessary tests, evaluate the results, and then discuss the risks and benefits with you.
