Criteria

Inclusion Criteria:

• Patients able to understand and sign a document of informed consent;

• Patients aged ≥49 years with age-related cataract formation;

• Patients planning to undergo surgical removal of cataract by phacoemulsification with implantation of a posterior chamber intraocular lens;

• Patients that have healthy eyes excluding the formation of cataract.

Exclusion Criteria:

• pseudoexfoliation syndrome with glaucoma or zonular compromise in the operative eye;

• A congenital ocular anomaly (e.g., aniridia, congenital cataract) in the operative eye;

• Iris atrophy in the operative eye;

• Glaucoma (including pseudoexfoliation or pigmentary) or any causes of compromised outflow in the operative eye;

• Any abnormality which prevents reliable Goldmann applanation tonometry in the operative eye;

• Ocular hypertension (lntraocular Pressure (IOP) > 21 mmHg) in the operative eye at the baseline exam;

• Corneal abnormality that results in a poor endothelial cell photograph and prevents reliable endothelial cell density measurement;

• Baseline endothelial cell density < 1500 cells/mm2, in the operative eye;

• Planned multiple procedures during cataract/Intraocular Lens (IOL) implantation surgery (e.g., trabeculoplasty, corneal transplant). NOTE: A minor relaxing keratotomy

• Patients 48 years of age or younger;

• Proliferative diabetic retinopathy in the operative eye;

• Uncontrolled diabetes mellitus;

• Marfan's Syndrome;

• An ocular disease and/or condition that may compromise results;

• A history of chronic or recurrent inflammatory eye disease (e.g. iritis, scleritis, uveitis, iridocyclitis, rubeosis iritis) in the operative eye;

• Lens for the correction of astigmatism may be performed;

• Previous ocular trauma to the operative eye (this includes previous intraocular surgery and traumatic cataract). NOTE: history of non-invasive laser surgery (with the exception of laser treatment for PDR) is acceptable for inclusion;

• A non-functional fellow eye;

• Participation in any other clinical study within the 30 days before surgery
