Background & aim: The studies have shown that by an increase in the aberrations and visual performance might be affected by the ocular aberrations after the corneal refractive surgery. This study was to investigate the effects of LASEK surgery on the ocular aberrations in hyperopic and hyperopic astigmatism patients.Methods: In this analytical & descriptive study 35 patients (11 men, 24 women) having LASEK surgery using the Technolas 217 z were divided into 3 groups of preoperative hyperopia as mild (+0.50-+1.75), moderate (+2.00-+3.00), and high (+3.25-+5.00). The preoperative and 6 month postoperative UCVA, BSCVA, subjective refraction, HOAs values of coma, trefoil, spherical aberration, 2nd astigmatism, quadrafoil, pentafoil, total higher-order aberrations were measured with 6mm pupils using the zywave II aberrometer. The mean spheric.. View More»
