Using the Femtosecond Laser to make a clear corneal incision.


Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
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.
