An excellent and comprehensive review of the subject, which also includes a worksheet for use by clinicians. The authors also discuss some of the newer technologies such as light-adjusted IOLs that may be of great benefit in the future for refinement of refractive status after surgery.

In this study, six central maps were performed using Orbscan to determine the central 2-mm power of the cornea after myopic LASIK. In addition, the authors also looked at the anterior-posterior corneal curvature after LASIK. The central 2-mm power determined by Orbscan-II was thought to be a true representation of the corneal power. In addition, the anterior-posterior ratio was found to be not constant, as assumed in the Gullstrand model eye. The authors present this as a direct corneal power measurement regardless of the data before refractive surgery
