PURPOSE TO COMPARE SPHERICAL ABERRATION AND CONTRAST SENSITIVITY WITH TWO DIFFERENT TYPES OF ASPHERIC POSTERIOR CHAMBER INTRAOCULAR LENSES (PCIOLS): Tecnis Z9000 versus Akreos AO. METHODS Thirty-four eyes of 34 patients undergoing phacoemulsification for senile cataracts were randomly assigned to implantation of Tecnis Z9000 or Akreos AO PCIOLs. Outcome measures included best-corrected visual...

PURPOSE To evaluate whether the Tecnis Z9000 intraocular lens (IOL) (Pfizer) with a modified prolate anterior surface provides better quality of vision than a conventional spherical IOL. SETTING Oregon Eye Institute, Eugene, Oregon, USA. METHODS Patients presenting for cataract surgery who were randomly assigned to receive a Tecnis Z9000 IOL (Pfizer) or a Sensar OptiEdge AR40e IOL (AMO) in ...

purpose: to compare tecnis z9000 and akreos ao aspheric intraocular lenses (iols) in terms of spherical aberration and contrast sensitivity. methods: thirty-four eyes of 34 patients undergoing phacoemulsification cataract surgery were randomly assigned for implantation of tecnis or akreos ao iols. three months postoperatively, best-corrected visual acuity (bcva), spherical aberration (with 4 an...

PURPOSE To compare the contrast sensitivity of an intraocular lens (IOL) with a modified prolate anterior surface (Tecnis Z9000, Pfizer), with 2 standard spherical IOLs (Sensar AR40e Opti-Edge IOL, AMO and AcrySof Natural SN60AT IOL, Alcon). METHODS In this prospective study, 98 eyes of 71 patients received 1 of 3 IOLs at random. After 6 months, best corrected visual acuity, pupil size and co...

Purpose: To assess the quality of vision in pseudophakic patients with a prolate aspherical intraocular lens (IOL) compared to patients with a spherical IOL. Patients and methods: Twenty patients undergoing cataract surgery were divided into two groups according to the type of IOL: ten prolate aspherical IOLs (TECNIS Z9000, AMO, USA) and ten spherical IOLs (911 CeeOn Edge, AMO, USA). The integr...

PURPOSE To compare ocular performance and quality of vision in pseudophakic eyes with an aspherical intraocular lens (IOL) or a conventional spherical IOL. SETTING Bretonneau University Hospital, Tours, France. METHODS Twenty patients (40 eyes) were randomly divided in 2 equal groups to bilaterally receive the aspherical Tecnis Z9000 IOL (AMO) or the spherical CeeOn Edge 911 IOL (AMO). Cont...

purpose: to compare tecnis z9000 and acrysof iq aspheric intraocular lenses (iols) regarding spherical aberration and contrast sensitivity. methods: thirty-four eyes of 34 patients undergoing phacoemulsification cataract surgery were randomly assigned to implantation of tecnis or iq iols. three months postoperatively, best-corrected visual acuity (bcva), spherical aberration (with 4 and 6 mm pu...
