Are You a Candidate for LASIK?

The best candidates for LASIK have an eyeglass prescription that isn’t extreme. If you are nearsighted, this means you may have myopia of up to –8.00 diopters. If you are farsighted, your hyperopia may be up to +3.00 diopters. Your level of astigmatism may be as high as +4.00 diopters. Patients outside of these ranges can still have LASIK, but they require a greater degree of corneal reshaping and expectations for crisp, clear vision are lower. Above –8.00 diopters of myopia, I usually recommend the implantable contact lens. Above +3.00 diopters of hyperopia, I prefer refractive lens exchange. Both of these options are covered in detail in later chapters.
