Primary Outcome Measures:
  • Changes in Symptoms [ Time Frame: SCR & 6 Month ] [ Designated as safety issue: No ]
    Quality of vision will be assessed using the National Eye Institute Visual Functioning Questionnaire - 25.

  • Participant Satisfaction [ Time Frame: SCR & 6 Month ] [ Designated as safety issue: No ]
    Participant satisfaction will be assessed using the Global Aesthetic Improvement Scale.

  • Complications and Adverse Events [ Time Frame: SCR & 6 Month ] [ Designated as safety issue: Yes ]
    Complications and adverse events will be assessed through tabulation of adverse events, changes in vision, cell density, intraocular pressure, and slit lamp exam.


Estimated Enrollment: 300
Study Start Date: October 2013
Estimated Study Completion Date: December 2015
Estimated Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: PMA Cohort
The artificial iris will be implanted in the eye with an iris defect. The fellow eye can be treated 1 month after the primary eye.
Device: Artificial Iris (CustomFlex)
Experimental: Compassionate Use Cohort
Study participants that do not meet the inclusion/exclusion criteria for the study may be enrolled in the compassionate use treatment arm. The artificial iris will be implanted in the eye with an iris defect. The fellow eye can be treated 1 month after the primary eye.
Device: Artificial Iris (CustomFlex)

  Eligibility

Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  2. Having a diagnosis of congenital or acquired full or partial iris defect in the study eye.
  3. Having symptoms of light sensitivity, photophobia, and/or glare in the study eye.
  4. Subjects should be pseudophakic, aphakic or require cataract extraction.
  5. Signed and received a copy of the signed written informed consent.
  6. Willingness and ability to comply with schedule for follow-up visits and postoperative evaluations.

Exclusion Criteria:

  2. Preoperative intraocular pressure > 21 mm Hg.
  3. Subjects with a current condition that, in the investigator's opinion, would interfere with the treatment.
  4. Subjects with any of the following conditions:

    1. Severe chronic uveitis
    2. Microphthalmus
    3. Untreated retinal detachment
    4. Untreated chronic glaucoma
    5. Rubella cataract
    6. Rubeosis of the iris
    7. Proliferative diabetic retinopathy
  5. Female subjects who are pregnant or lactating at the time of surgery.
  6. Subjects with a known sensitivity to required postoperative study medications (4th generation fluoroquinolone or steroid anti-inflammatory) if an alternative medication is not available.
  7. Subjects under legal guardianship or who, in the investigator's opinion, lack the mental capacity to provide written informed consent for study participation.
  8. Stargardt's retinopathy.
  9. Subjects with gastric ulcers or diabetes mellitus in whom high doses of postoperative steroids are required.
  10. Surgical difficulty of the planned surgery, which might increase the potential for complications.
  11. No useful vision or vision potential in the fellow eye.
  12. Clear crystalline lens.
  13. Implantation of a CustomFlex Artificial Iris prosthesis in the contralateral eye within the previous 4 weeks.
  14. In the investigator's opinion, the presence of a condition or finding in the contralateral eye that would make it unsafe to implant a CustomFlex Artificial Iris prosthesis in the study eye.
