Orbital Implants Receiving Food and Drug Administration Premarket Notification.

Area of Science:

• Medical Device Regulation
• Ophthalmic Surgery
• Biomaterials

Background:

• The Food and Drug Administration (FDA) 510(k) program, or premarket notification, allows Class II medical devices like orbital implants to reach the market faster.
• This process relies on demonstrating substantial equivalence to existing devices, rather than rigorous clinical safety standards.

Purpose of the Study:

• To evaluate the FDA's 510(k) clearance process for orbital implants.
• To identify potential shortcomings in the premarket notification pathway for these devices.

Main Methods:

• A comprehensive search of the FDA's 510(k) Premarket Notification database was performed.
• Data on FDA-cleared orbital implants from 1976 to 2022 were analyzed.

Main Results:

• Between 1987 and 2022, 29 orbital implants received 510(k) clearance.
• Four of these implants were recalled, and 3 were cleared based on predicate devices that were later recalled.
• Data on predicate devices were available for only 9 of the 29 implants.

Conclusions:

• The FDA's 510(k) process may allow devices to be cleared based on substantial equivalence to previously recalled implants.
• This raises concerns about long-term implant safety and associated morbidity.
• Clinicians need to be aware of the 510(k) approval pathway and the implications of substantial equivalence to recalled devices.
