About this trial

This is an interventional treatment trial for Cataract focused on measuring Cataract, Capsulotomy, Capsulorrhexis, lens fragmentation, phacoemulsification

Eligibility Criteria

21 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

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.
