Overview

This is study to determine the visual performance of patients with age-related cataracts implanted in both eyes with either of two extended depth of focus intraocular lenses, the Clareon Vivity (Alcon Healthcare) or the PureSee (Johnson & Johnson)

Eligibility

Inclusion Criteria:

• Patients of any sex and race aged 50 years or older
• Patients undergoing bilateral age-related cataract surgery with a lens opacity grade 3 or higher in the LOCS III grading scale
• Willing to receive implantation of an EDOF IOL
• Willing to sign the informed consent and attend the study visits

Exclusion Criteria:

• Requirement of a spherical or toric power of the IOL to achieve emmetropia beyond the available range of either of the two lenses
• The number of patients included with low astigmatism that require an equivalent to a T2 toric IOL will be capped to 10 patients/group
• Irregular astigmatism
• Contact lens wear in the previous 3 weeks before biometry
• Moderate or severe ocular surface, corneal, macular or optic nerve disease that in opinion of the investigator precludes the desired functional results
• History of previous refractive, cornea, retina or glaucoma surgery
• Eyes with a clear lens demanding a refractive lens exchange
• Amblyopia in any eye
• Significant previous ocular trauma
• Pregnancy
• A systemic condition that, in the opinion of the investigator, precludes the reliable assessments required in the study (i.e., dementia) or participation in the study (i.e., severe mobility problems).
