A pinhole occluder is then placed before the patient's eye, and their vision is then tested again (each eye separately) to determine if the patient's poor visual acuity is a result of optical irregularities, or pathological issues.

Tests of reading performance indicated that a 60-channel implant is sufficient to restore some reading ability, but only with significantly enlarged text. [20] Similar experiments evaluating room navigation ability with pixelated images demonstrated that 60 channels were sufficient for experienced subjects, while naïve subjects required 256 ...
