The purpose of this study was to prospectively compare high-order aberrations between eyes implanted with the AcrySof® Natural IQ (SN60WF) intraocular lens (IOL) versus those implanted with the Tecnis ZCB00 IOL.

Inclusion Criteria:

• Requires bilateral extraction of cataracts by phacoemulsification followed by implantation of a posterior chamber intraocular lens;
• Confirmed absence of pre-existing conditions that could skew the results or present contraindications for the IQ intraocular lens (IOL) or the Tecnis ZCB00 IOL;
• <1 diopter corneal astigmatism preoperatively;
• Able to achieve 6.5 mm dilated pupil;
• Other protocol-defined inclusion criteria may apply.

Exclusion Criteria:

• Chronic disease or illness;
• Irregular optical aberration;
• Amblyopia;
• History of corneal disease (e.g., herpes simplex, herpes zoster keratitis, etc.);
• Diabetic retinopathy;
• Macular degeneration;
• History of retinal detachment;
• Other surgeries planned at time of cataract removal;
• Severe dry eye;
• Other protocol-defined exclusion criteria may apply.
