Clinical evaluation of preloaded aspheric IOL implantation / 眼科

ABSTRACT

Objective To evaluate the clinical efficacy after implantation of preloaded aspheric intraocular lens.Design Retrospective case series.Participants 74 patients(82 eyes)with age-related cataract38 patients(43 eyes)in group A(control group),36 patients(39 eyes)in group B(case group).Methods 74 patients(82 eyes)were randomly selected to receive phacoemulsification with KS-3(group A)and KS-3Ai(group B)IOL implantation.The wavefront aberrations and contract sensitivity were measured 3 months post-operatively.Main Outcome Measures Wavefront aberrations and contract sensitivity.Results No complications occurred in both gruops.In 1.0deg,0.7deg,the mean contract sensitivity in group A were lower than those in group B(t =3.69,2.71;P
