2. Operable, age related cataract grade in both eyes
3. Patients who require an intraocular lens (IOL) power in the range of 15 D - 30 D only
4. Able to comprehend and sign a statement of informed consent
5. Calculated lens power within the available supply range
6. Planned cataract removal by phacoemulsification
7. Potential postoperative visual acuity of 0.2 Logarithm of the Minimum Angle ofResolution (logMAR) or better in both eyes
8. In good general and ocular health
9. Patients with preoperative astigmatism ≤1.0 D Note: Corneal incisions made to reduceastigmatism will not be allowed during the course of the study.
10. Clear intraocular media other than cataract in study eyes
11. Preoperative Best Corrected Distance Visual Acuity (BCDVA) worse than 0.2 logMAR
12. The subject must be able to undergo second eye surgery between 7 days and 30 days ofthe first eye surgery
13. Able to competently complete testing
14. Willing and able to attend study visits

Exclusion Criteria:

1. Previous intraocular surgery
2. Preoperative photopic pupil size of < 2.75 mm
3. Previous corneal refractive surgery
4. Any inflammation or edema (swelling) of the cornea
5. Subjects with diagnosed degenerative visual disorders (e.g. macular degeneration orother retinal disorders ) that are predicted to cause future acuity losses to a levelworse than 0.2 logMAR
6. Subjects who may reasonably be expected to require a secondary surgical interventionat any time during the study (other than neodymium-doped yttrium aluminium garnet (nd:YAG) capsulotomy)
7. Amblyopia
8. Clinically significant ptosis
9. Clinically severe corneal dystrophy (eg., epithelial, stromal, or endothelialdystrophy), keratitis, keratoconjunctivitis, keratouveitis, keratopathy, or kerectasia
10. Diabetic Retinopathy
11. Extremely shallow anterior chamber, not due to swollen cataract
12. Microphthalmia
13. Previous retinal detachment
14. Previous corneal transplant
15. Severe dry eye
16. Recurrent severe anterior or posterior segment inflammation of unknown etiology
17. Systemic medications that may confound the outcome or increase the risk to the subjectin the opinion of the Investigator [tamsulosin hydrochloride (Flomax) or othermedications with similar side effects (floppy iris syndrome)]
18. Rubella or traumatic cataract
19. Iris neovascularization
20. Glaucoma (medically controlled or uncontrolled)
21. Aniridia
22. Chronic severe uveitis
23. Optic nerve atrophy
24. Corneal decompensation
25. Greater than 1.0 D of astigmatism
26. History of corneal disease (e.g., herpes simplex, herpes zoster keratitis, etc.)
27. Pseudoexfoliation syndrome
28. Iris atrophy
29. Pupil abnormalities (e.g., corectopia)
30. Aniseikonia
31. An acute or chronic disease or illness that may confound the results of thisinvestigation (e.g., immunocompromised, connective tissue disease, clinicallysignificant atopic disease, diabetes, and any other such disease or illness)
32. Pregnant, lactating, or planning to become pregnant during the course of the trialNote: Subjects who become pregnant during the study will not be discontinued; however,data may be excluded from the effectiveness analyses because pregnancy can alterrefraction and visual acuity results.
33. Participation in another clinical trial within 30 days of study start
