تغییرات رفراکتیو و توپوگرافیک قرنیه پس از عمل جراحی

  Background & Aim: Refractive change after strabismus surgery is a known phenomenon which may be attributed to the extraocular muscle traction.Since previous studies were often done by conventional methods,accompanied by a short follow-up, and without considering simultaneous evaluation of both refractive and topographic changes, this study was organized to evaluate refractive and topographic ...

Surgically induced astigmatism: distinguishing between dioptric vectors and non-vectors.

To the Editor: I read with interest the October editorial, “JRS Standard for Reporting Astigmatism Outcomes of Refractive Surgery”1 by Reinstein et al.; however, some clarification is required. I advocated common standards for reporting surgically induced astigmatism in 1997.2 In 2008, a comprehensive analysis of assessment methods and statistical analysis of surgically induced astigmatism was ...

Astigmatism induced by conventional spherical ablation after PRK and LASIK in myopia with astigmatism < 1.00 D

BACKGROUND The purpose of this study was to evaluate surgically-induced astigmatism after spherical ablation in photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK) for myopia with astigmatism < 1.00 D. METHODS The charts of patients undergoing spherical PRK or LASIK for the correction of myopia with minimal astigmatism of <1.00 D from 2002 to 2012 at the John A...
