Comparative study of aspheric intraocular lenses with negative spherical aberration or no aberration

PURPOSE: To compare the quality of vision with an aspheric intraocular lens (IOL) with no aberration and an IOL with negative spherical aberration. SETTING: Bretonneau University Hospital, Tours, France. METHODS: Patients scheduled for cataract surgery were randomly chosen to bilaterally receive a SofPort Advanced Optics IOL with no aberration (no-aberration IOL group) or a Tecnis Z9000 IOL with negative spherical aberration (negative-aberration IOL group). Six-month postoperative outcomes included patient-centered visual disability assessed with the Activities of Daily Vision Scale (ADVS), contrast sensitivity testing, and wavefront aberration analysis. RESULTS: There was no difference in the overall ADVS score between the 2 groups (P = 0.07); however, the negative-aberration IOL group had a better night-driving score (mean 82.7 +/- 15.1 [SD] versus 66.4 +/- 7.6) (P Language: en
