Objective:
To assess recent high-risk ophthalmic medical device recalls.
Methods:
The publicly available Food and Drug Administration Center for Devices and Radiological Health database was mined for Class I (high-risk) ophthalmic device recalls from January 1, 2003 to December 31, 2015. The number of Class I ophthalmic device recalls was quantified. Additionally, recall characteristics and market entry data were determined for each device.
Results:
Twelve Class I ophthalmic device recall events were identified, collectively affecting over 68 million units in distribution. A median of 147,491 units (range 20 to 57,252,581) were recalled per event. 9 out of 12 recalls (75%) had at least one documented occurrence of an adverse event to a patient. Pre-market related issues accounted for one device recall (8%), post-market related issues accounted for nine device recalls (75%), and two device recalls (17%) were indeterminate. 510(k) clearance was the most common pathway to market, accounting for 50% of Class I recalls. Three devices were approved through pre-market approval (PMA) pathway, two devices were exempt from review, and one device failed to register with the FDA.
Conclusion:
Class I recalls surrounding ophthalmology are relatively infrequent compared to other medical specialties. However, given the impact of Class I recalls in the field, ophthalmologists have an impetus to advocate for stronger device regulation particularly in the context of post-marketing surveillance.

Anatomy of the Brain: Major Regions
The cerebrum is the largest section of the brain and divides into left and right hemispheres, separated by a deep fissure. The cerebral outer layer of grey matter — the cerebral cortex — comprises elevations called gyri and shallow groves called sulci. The inner portion of white matter includes long nerve fibers known as axons, which connect...
