title: Metaanalysis of intraocular lens power calculation after laser refractive surgery in myopic eyes.
abstract: To evaluate the accuracy of intraocular lens (IOL) power calculation methods after laser refractive surgery in myopic eyes, a comprehensive literature search was carried out for retrospective case series studies with data on post-myopic laser surgery IOL power calculations published from January 2000 to May 2014. A metaanalysis of the 9 identified studies was performed using odds ratios in percentage of prediction error within ±0.5 or 1.0 diopter (D) of the target refraction. Compared with the Haigis-L method, the clinical history method, corneal bypass method, and Feiz-Mannis method were associated with lower odds of predication; the Masket method showed higher odds. The subgroup data showed significantly better performance of the Shammas no-history method with the Shammas post-LASIK formula than the Haigis-L method in predication error. The Masket method and the Shammas no-history method with the Shammas post-LASIK formula without historical data had more prediction accuracy than the Haigis-L method. The clinical history method, Feiz-Mannis method, and corneal bypass method, which required historical data, were less accurate in their predictions.
