The LensAR Laser System is used to create an opening in the anterior capsule of the lens and fragments the cataractous lens. The study will evaluate clinical outcomes compared to the contra-lateral eye treated with conventional phacoemulsification surgery.

Condition Intervention Phase
Cataract Device: LensAR Laser System Device: Conventional phacoemulsification Phase 2 Phase 3

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Prospective Clinical Trial of the LensAR Laser System in the Treatment of Cataracts of Different Grades of Maturity

Estimated Study Completion Date: June 2011
Estimated Primary Completion Date: June 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Laser Treatment Device: LensAR Laser System
Use of laser for capsulotomy and lens fragmentation

Use of standard techniques for capsulotomy and lens fragmentation


Ages Eligible for Study:   21 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Subjects must sign and be given a copy of the written informed consent form
  • Subjects must have elected to undergo lens extraction and IOL implantation and then elect to have the LensAR laser surgery as part of the procedure.
  • Subjects must be willing and able to return for scheduled follow-up examinations for 6 months after surgery.
  • Subjects must have central 7 mm of clear cornea without vascularization.

Exclusion Criteria:

  • Subjects who have undergone previous corneal or intraocular surgery in the eye to be treated.
  • Subjects with a history, signs or symptoms of ocular disease or atypical finding which would be contraindicated under standard of care for cataract surgery.
  • Diabetic or hypertensive subjects with clinical evidence of retinal pathology.
  • Subjects with macular degenerative pathology.
  • Subjects with a history of steroid-responsive rise in IOP or uncontrolled glaucoma in either eye.
  • Subjects with known lens/zonular instability such as, but not restricted to, Marfan's Syndrome, Pseudoexfoliation Syndrome, etc.
  • Subjects with corneal disease or pathology that precludes applanation of the cornea or transmission of laser wavelength or distortion of laser light.
