Randomized Comparison of the Abbott WHITESTAR Signature System With Ellips Tranversal Ultrasound vs. the Alcon Infiniti With the Ozil Torsional Handpiece in Phacoemulsification: A Contralaterally-Controlled Trial

Randomized Comparison of the Abbott WHITESTAR Signature System With Ellips Tranversal Ultrasound vs. the Alcon Infiniti With the Ozil Torsional Handpiece in Phacoemulsification: A Contralaterally-Controlled Trial

The purpose of this study is to look at the outcomes of your vision after your cataract surgery based on two different types of equipment that will be used during your surgery.

Inclusion Criteria:

• Patients at least 21 scheduled to undergo bilateral phacoemulsification with implantation of multifocal IOLs.
• Both eyes must have similar degrees of cataract and astigmatism (topographic cylinder difference of <2.00D as well as similar globe axial length as measured by the IOL Master of <0.5mm).
• Visual potential of UCVA 20/25/ or better.
• Clear intraocular media other than cataract.

Exclusion Criteria:

• Clinically relevant differences between eyes in ocular disease or pathology.
• Presence of glaucoma, macular disease, or foveal disease to an asymmetrical degree.
• Asymmetrical use of ocular medications.
