Eligibility Criteria

Inclusion Criteria

•Bilateral cataracts
•40\~80 years of age
•4 Days - 1 Week interval between a single patient's surgery
•dilated pupil size (in dim light) ≥ 4.0 mm
•Anticipated correction with an IOL of +10 Diopters \~ +25 Diopters
•0.75 - 2.0 Diopters of astigmatism preoperatively as measured by Keratometry readings

Exclusion Criteria

•Preoperative ocular pathology
•Previous intraocular or corneal surgery
•An increased risk for complications which could require vitreoretinal surgery
•Corneal irregularities
•Corneal opacities
•Current contact lens usage(within 6 months prior to first surgery)

Outcomes

Primary Outcomes

Uncorrected Visual Acuity (UCVA)

Time Frame: 6 Months after surgery

Uncorrected Visual Acuity (UCVA) from surgery measured in logMAR. LogMAR is the "logarithm of the minimum angle of resolution". A lower logMAR value indicates better visual acuity.
