Abstract PURPOSE. The Collaborative Longitudinal Evaluation of Refractive Error and Ethnicity (CLEERE) Study was initiated in 1997 to investigate ocular and refractive error in various ethnic groups.

METHODS. Children in grades 1 through 8 were recruited and examined during the 1997-98 academic year at four clinical sites. The four ethnic groups (per parent report) represented in this sample were Caucasians (n=1,028), African-Americans (n=532), Hispanics (n=460), and Asians (n=550). Refractive error, axial length, and corneal curvature were measured using cycloplegic autorefraction, A-scan ultrasonography, and autokeratometry.

RESULTS. Refractive error distribution differed significantly by ethnic group with the highest prevalence of myopia (defined as at least -0.75 D of myopia in each principal meridian) among the Asians (17.1% myopic, mean vertical meridian 0.37 +/- 1.77 D), the lowest prevalence of myopia among the Caucasians (4.2% myopic, mean vertical meridian 1.21 +/- 1.19 D) and the Hispanics and African-Americans intermediate (14.2% and 6.4% myopic and mean vertical meridian 0.57 +/- 1.80 D and 0.48 +/- 1.21 D respectively; chi-square = 90.55, pCHANGES IN CORNEAL ABSORBANCE AFTER PHOTOREFRACTIVE KERATECTOMY IN RABBITS
