Yes laser eye surgery can correct high prescriptions and the range it can treat has greatly increased over the past few years. Laser eye surgery can treat a higher degree of short sightedness(minus prescriptions eg -4.00) compared with long sightedness (plus prescriptions eg +4.00). Laser eye surgery can treat up to -12.00 (short sighted) and + 5.00 (long sighted). It can treat upto -/+ 6.00 astigmatism. These figures however relate to the maximum that can be treated and the limiting factor is the thickness of your cornea. In order for the laser to reshape such a large amount of presciption you will need to have a thick enough cornea. This will be assessed in your laser eye surgery consultation.
