Femtosecond Laser System For Refractive Correction

Page Type
Product Code
Definition
Ophthalmic femtosecond laser intended to provide refractive vision correction by modification of the shape of the cornea
Physical State
The device consists of a laser console, a computer with graphic user interface, a beam delivery system that positions and focuses the laser beam, patient bed, and a patient interface system that flattens the cornea and holds the patient's eye still during the surgical procedure.
Technical Method
The laser console generates femtosecond laser pulses. When focused in transparent tissue, these low energy pulses produce photodisruption (a highly localized region of ionized plasma) effects that occur on an extremely short time scale and are confined to the few microns surrounding the focal spot. Patterns of contiguous, focused laser pulses result in the creation of cut surfaces in the cornea that define a disc-shaped tissue (lenticule) in the corneal stroma. The surgeon enters treatment parameters and a corresponding lenticule is created according to a pre-defined algorithm such that its thickness determines the refractive correction and resultant corneal reshaping when extracted.
Target Area
Cornea of the eye.

No Linked CFR Text

The FDA has not linked product code OTL to any particular section of the CFR (Code of Federal Regulations). There are multiple reasons why this might be the case:

  • The product code was created for a class III submission that does not follow the normal PMN or PMA path - e.g., for a device that falls under HDE (Humanitarian Device Exemption) or EUA (Emergency Use Authorization).
  • The FDA has generated the product code for an existing Class III device, as a result of a PMA supplement that modifies the device in a way that it can't fit under the existing product code originally assigned
  • The product code was created for internal use at the FDA, and not for classification or regulatory-related purposes.
