入选标准
- •Is 25 years or older at the date of enrolment
- •Has a confirmed diagnosis of retinitis pigmentosa, choroideremia or cone-rod dystrophy
- •Has a visual acuity of logMAR 2.3 or worse in both the eyes as determined by a Square Grating scale.
- •Has functional ganglion cells and optic nerve activity
- •Has a memory of former useful form vision
- •Understands and accepts the obligation to present for all schedule follow-up visits.
- •Has AP eye dimensions that are appropriate with the dimensions of the implant(In Germany: Has an AP eye dimension between 20.5 and 25 mm)
- •Has head dimensions that are appropriate for visual Interface.
排除标准
- •Has a history of severe glaucoma, uveitis, optic neuropathy or any confirmed damage to the optic nerve and/or visual cortex,
- •Has any disease (other than study allowed diseases) or condition that affects retinal function of the study eye (e.g., central retinal artery/vein occlusion, end-stage diabetic retinopathy, current or prior retinal detachment, infectious or inflammatory retinal disease, etc.),
- •Has any disease or condition that prevents adequate visualization of the retina of the study eye including, but not limited to, corneal degeneration that cannot be resolved prior to implantation,
- •Has any disease or condition of the anterior segment of the study eye that prevents adequate physical examination (e.g., ocular trauma, etc.),
- •Has severe nystagmus,
- •Has any ocular condition that leads him or her to eye rubbing,
- •Has any disease or condition that precludes the understanding or communication of the informed consent, study requirements or test protocols (e.g., deafness , multiple sclerosis, amyotrophc lateral sclerosis, neuritis, etc),
- •Has a history of epileptic seizure,
- •Has a history of chronic or recurrent infection or inflammation that would preclude participation in the study,
- •Has a known sensitivity to the contact materials of the implant,
- •Presents with hypotony in the study eye,
- •Presents with hypertony in the study eye,
- •Is pregnant or lactating,
- •Has another active implanted device (e.g. cochlear implant) or any form of metallic implant in the head (other than dental work) that may interfere with the device function,
- •Has a diagnosis requiring an active implant (e.g., cardiac pacemaker, vagus nerve implant, etc.),
- •Has active cancer or a history of intraocular, optic nerve or brain cancer and metastasis,
- •Is an immune-suppressed subject (e.g., due to HIV positive diagnosis, etc.),
- •Is carrier of multi-resistant germs,
- •Requires the use of any of the following medications:
- •Antimetabolites,
- •Thrombocyte aggregation reducing therapies (10 days prior until 3 days after surgery),
- •Oral anticoagulants (5 days before until 3 days after surgery),
- •Is participating in another investigational drug or device study that may interfere with the proposed treatment or the ensuring follow-up schedule, (in Germany: Is participating in another investigational drug or device study)
- •Has any health concern that makes general anaesthesia inadvisable, (in Germany: Patients with an ASA-Score of 3 or higher are excluded from the study)
- •Is likely requiring MRI scans subsequent to implantation and prior to explantation,
- •Is likely requiring therapeutic ultrasound subsequent to implantation and prior to explantation of the Retinal Implant
- •In Germany: - Patients with recurrent or chronic inflammations or infections are excluded from the study. Specifically patients with the following disorders are excluded:
- •Common inflammation - severe chronic and consuming diseases that frequently associated with infection (e.g. Crohn disease, Whipple's disease)
- •Chronic inflammation of the skin in the area of the eye (e.g. dermatitis, rosacea, infection of the skin, herpes zoster)
- •Chronic inflammation in the area of the eye (e.g. herpes of cornea and/or conjunctiva, recurrent blepharoconjunctivitis, horedolum, chalazion) In Germany: - Has a severe psychological disorder. When in any doubt, an expert assessment needs to be arranged to clarify whether the patient's psychological health is suitable for the trial.
- •In Germany: - Has severe renal, cardiac, hepatic etc. organ diseases
结局指标
主要结局
Number of Adverse Events as a Measure of Safety and Tolerability
时间窗: Up to 18 month after implantation
All subjects undergo ophthalmological examinations in predefined intervals after implantation. Ophthalmological examinations include funduscopy, slit lamp examination and OCT. All adverse events are recorded and analysed.
次要结局
- Probable benefit(Up to 18 months after implantation)
