Telescope Exchange Study

Exclusion Criteria

• •Stargardt's macular dystrophy
• •Cognitive impairment that would interfere with the ability to understand instructions, follow directions, or prevent proper visual training/rehabilitation with the device.
• •Any ophthalmic pathology that compromises fellow-eye peripheral vision
• •A history of steroid-responsive rise in intraocular pressure (IOP), uncontrolled glaucoma, or preoperative IOP \>22mmHg while on maximum medication
• •Known sensitivity to planned study concomitant medications.
• •An ocular condition that predisposes the patient to eye rubbing.
• •Patients participating in any other ophthalmic drug or device clinical trial during the time of this clinical investigation.
• •Operative eye with:
• •* Evidence of active CNV or treatment of CNV within 6 months

• •* Central anterior chamber depth (ACD) \< 3.0 mm; measurement of the ACD should be taken from the posterior surface of the cornea (endothelium) to the anterior surface of the IOL.
• •* Axial length \< 21 mm or \>27 mm
• •* Endothelial cell density (ECD) lower than 2300 cells/mm2 for subjects between the ages 65-69, lower than 2000 cells/mm2 for subjects between the ages of 70-74, and lower than 1800 cells/mm2 for subjects 75 years old or greater.
• •* Corneal stromal or endothelial dystrophies, including guttata
• •* History of intraocular or corneal surgery (including DSEK) except cataract removal and IOL placement
• •* History of complicated cataract surgery
• •* Compromised capsular bag (previous YAG posterior capsulotomy, evidence of tearing)

• •* Inflammatory ocular disease
• •* Pseudoexfoliation or zonular weakness
• •* Diabetic retinopathy
• •* Untreated retinal tears
• •* Retinal vascular disease
• •* Optic nerve disease
• •* A history of retinal detachment
• •* Intraocular tumor
• •* Retinitis pigmentosa
• •* Prior or expected ophthalmic related surgery within 30 days preceding telescope implantation
• •* Any medical or ophthalmic condition that in the opinion of the investigator renders the subject unsuitable for participation in the study
