High hyperopic astigmatism
WebAstigmatism did not change over time. Conclusions: Most preschool children in this highly astigmatic population are hyperopic, with astigmats showing higher mean hyperopic sph eq than non-astigmats. Astigmats and non-astigmats show a similar decrease in amount of hyperopic sph eq over follow-up of 4 to 8 years. WebObjective: To describe LASIK for hyperopia, hyperopia with astigmatism, and mixed astigmatism and to examine the evidence to answer questions about the safety and efficacy of the procedure. Methods: A literature search conducted for years 1968 to 2002 retrieved 118 citations.
