4 Clinical Trials for Various Conditions
This is a prospective comparative study that will be conducted at one clinical site in the United States, in which subjects who sign an informed consent form and fulfil all inclusion and exclusion criteria, will have OCT scans obtained using the test and the predicate devices. There will be two main types of analyses performed as part of this study, including 1) a precision analysis, and 2) an agreement analysis. The precision analyses will be conducted utilizing all complete complements of acceptable scans from the test devices and predicate device for each of the 3 configurations. A complete complement of acceptable scans can be defined as subjects having 3 acceptable replicate scans on each of the 3 devices, at each of the 3 configurations. This is also synonymous with 3 scans for each of the 3 configurations on all 3 devices. If subjects have more than 3 acceptable scans per configuration on a device, only the first 3 will be considered for analyses. The agreement analysis will be conducted utilizing the first set of acceptable scans from each instrument for all overlapping measurement types (for all measurement types two or more of the devices have in common) related to performance endpoints.
The primary purpose of this comparative clinical study is to collect clinical data to demonstrate the equivalence of the investigational device to the predicate device for measurements of the eye. The secondary purpose is to evaluate any adverse events that occur during the clinical study.
The objective of this study is to explore the perception of pain during intravitreal injection related to the distance of the entry site from the limbus.
The purpose of this multi-center clinical trail is to determine the safety and efficacy of the iSert 251 for the correction of aphakia.
