Question: I wear -20.00 D power contact lenses. Am I a candidate for Laser Eye Surgery such as LASIK?
Answer: LASIK and other types of Laser Eye Surgery such as PRK are useful for correcting moderate and some degrees of high myopia. At -20.00 D you would be classified as extreme myopia. Most currently FDA approved excimer lasers for LASIK allow a maximum correction of -10.00 D-12.00 D with any degree of precision. In addition the real limitation is not actually just the laser programming but more importantly that Laser Eye Surgery for Laser Vision Correction is a "subtractive" procedure in that it removes tissue. It is highly unlikely that there would be enough corneal tissue to safely and predictably remove enough tissue to achieve a -20.00 D correction.
Depending on your age and the overall health of your eyes more appropriate choices might be the Visian ICL™ Implantable Collamer Lens or perhaps Lens Replacement Surgery. Your best next step is to schedule a consultation with a top LASIK Surgeon who is also a full scope Refractive surgeon and also performs Lens Implants and Lens Replacement procedures.
