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

  • Uncorrected and Best corrected Visual Acuity [ Time Frame: three 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 Mento Potential Acuity Meter (PAM)laser interferometer, McIntyre Pinhole, or his/her judgement to estimate the patient's potential acuity.

Exclusion Criteria:

  • Concurrent participation or participation in the last 30 days in other clinical trials.
  • Known steroid IOP responder.
  • Taking medications that may affect vision, IOP, or ease of cataract surgery (e.g. Flomax, Glaucoma medications, 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 (>or =20hg) or glaucomatous changes in the optic nerve.
