Inside Eye = LARGER Field of View
New Category Device and Procedure
• Medical Device: the telescope is entirely different from an IOL - treats AMD (and not cataract)
• Procedure: Implanting the telescope is entirely different from inserting an IOL

• No new equipment
• Device is not an IOL
• 12 mm limbal incision & large capsulorrhexis
• Posterior direction and OVDs critical to avoid corneal touch

FDA Pivotal Trial: 28-Centers
19
• Prospective, 28 US centers• Multi-disciplinary approach
– “Vision training” 6 visits over first 3 months
• 217 visually impaired patients enrolled– Mean Age 76 years – Mean BCVA 20/316 (range: 20/80 – 20/800)
• Follow-Up– 12 months: n=194 of 206 implanted (11
received IOL instead of telescope prosthesis)– 24 months: n=174 of 206 implanted
Phase II/III IMT002 Trial(2002 – 2004)
20
One-Year Results Summary
Efficacy• FDA VA endpoint met
– 90% ≥ 2 lines vs. 50% required• 67% improved ≥ 3 lines BCDVA
– vs. 10% of control fellow eyes (p<.0001)• Improved quality of life
– VFQ increase 7-14 points (relevant subscales)
Safety• Preservation of vision: 95%• Endothelial cell density >17% target• Implant well tolerated in eye
21
IMT Restores Functional Sight in Blind Patients (5-year follow-up data)
• Pre-IMT vision of 20/320 or worse (statutory blindness)• Significant & sustained improvements in vision (long-term)
FDA Summary of Safety and Effectiveness Data
BCDVA = Best-Corrected Distance Visual Acuity22
Large, Clinically Significant Visual Gain
Intraocular lenses (IOLs) for cataract do not work for End-Stage AMD
