Primary Outcome Measures:
  • Intraocular Pressure [ Time Frame: 3 months ] [ Designated as safety issue: No ]
    Measure the fluid pressure inside the eye

  • Uncorrected and Best corrected Visual Acuity [ Time Frame: one month ] [ Designated as safety issue: No ]
    Vision obtained with the best possible lens correction (Best corrected). Vision obtained without the use of glasses or contact lenses (Uncorrected).

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Study participants must have a cataract for which phacoemulsification extraction and posterior IOL implantation has been planned in at least one eye.
  • Study participants should be capable of achieving better than 20/30 Snellen best corrected distance vision after cataract extraction and IOL implantation.

    • The surgeon may use the Mentor Potential Acuity Meter (PAM) laser interferometer, McIntyre Pinhole, or his/her judgment to estimate the patient's potential acuity.

Exclusion Criteria:

  • Concurrent participation or participation in the last thirty days in any other clinical trial.
  • Known steroid IOP responder
  • Taking medications that may affect vision, IOP or ease of cataract surgery (e.g., Flomax, Glaucoma mediations, etc.)
  • Acute or chronic disease or illness that would increase risk or confound study results (e.g., uncontrolled diabetes mellitus, immunocompromised, etc.)
  • Uncontrolled systemic or ocular disease
  • Corneal abnormalities (e.g., stromal, epithelial or endothelial dystrophies)
  • Pseudoexfoliation
  • Ocular hypertension IOP >25 mmHg by tonometry or glaucomatous changes in the optic nerve
