title: Theory behind surgical correction of presbyopia.
abstract: This relatively new procedure is interesting, promising, and appears to be safe. These issues are currently being evaluated by the US FDA and in several other countries, most notably Canada. The procedure is based on Ronald A. Schachar's new theory of how accommodation occurs. The clinical course of the patients and the new wavefront analysis appear to support the theory. Regardless of the exact mechanism, clinically, the patients read and behave as though they have had their accommodation restored. The author certainly has been very impressed and excited with the results in his patients whose surgeons he has proctored.
