Purpose: To compare visual acuity, aberrometry, and contrast sensitivity in eyes with spherical intraocular lens (IOL) and aspheric IOL implanted after uncomplicated phacoemulsification.
Setting: Department of Ophthalmology, University Hospital, Hradec Králové, Czech Republic.
Methods: A prospective clinical study involving 90 patients (105 eyes) having cataract surgery, with implantation of spherical IOL AcrySof Natural (SN60AT) in 45 patients (50 eyes) with a mean age of 62.5 years, and aspheric IOL AcrySof IQ (SN60WF) in 45 patients (55 eyes) with a mean age of 64.5 years. A control group involved 22 eyes of similar age with clear lens crystallina. Postoperatively, visual acuity (ETDRS charts), aberrometry (ORK Wavefront Analyser, Schwind), and contrast sensitivity tests (CSV 1000, Contrast Sensitivity 8.. View More»
