PURPOSE To evaluate the predictability of intraocular lens (IOL) power calculations using the IOLMaster and four different IOL power calculation formulas (Haigis, Hoffer Q, SRK II, and SRK/T) for cataract surgery in eyes with a short axial length (AL). METHODS The present study was a retrospective comparative analysis which included 25 eyes with an AL shorter than 22.0 mm that underwent uneve...

Purpose. To evaluate and compare the accuracy of different intraocular lens (IOL) power calculation formulas for eyes with an axial length (AL) greater than 26.00 mm. Methods. This study reviewed 407 eyes of 219 patients with AL longer than 26.0 mm. The refractive prediction errors of IOL power calculation formulas (SRK/T, Haigis, Holladay, Hoffer Q, and Barrett Universal II) using User Group f...

PURPOSE To analyze the accuracy of the Holladay 2 formula, which has been proposed as an improvement over the original Holladay formula. METHODS This retrospective analysis comprised 317 eyes operated on by 1 surgeon using 1 technique and 1 intraocular lens style in a specialty practice. Because the Holladay 2 formula has yet to be published, its accuracy can only be analyzed using the commer...

PURPOSE To compare the accuracy of intraocular lens (IOL) power calculation formulas in eyes with primary angle closure glaucoma (ACG). METHODS This retrospective study compared the refractive outcomes of 63 eyes with primary ACG with the results of 93 eyes with normal open angles undergoing uneventful cataract surgery. Anterior segment biometry including anterior chamber depth, axial length,...

Sociology of Education 2009, Vol. 82 (July): 267–286 267 Beginning with an analysis of the High School & Beyond survey in the early 1980s, James S. Coleman and his colleagues developed an important sociological literature on differences in achievement between public and private high schools (for overviews of the research, see Marsden 2005; Schneider 2000). In contrast to public schools, Coleman...

PURPOSE To evaluate the possible benefits of biometry and ray-tracing intraocular lens (IOL) calculation for aspheric aberration-correcting IOLs. SETTING Private eye clinic in Germany. DESIGN Retrospective consecutive case series. METHODS Eyes with 3 different aberration-correcting IOLs were reviewed. Before surgery, the axial length, corneal thickness, anterior chamber depth, crystalline...

Reviewer Williamjames Hoffer explains that Segregating the New South "is an important contribution to history of South, Black America, and origins Jim Crow" convincingly challenges idea segregation began after Reconstruction, as otherwise argued by "C. Vann Woodward his successors."
