A system records browsing activity of a user using a browser. Backplane controller includes: processor, memory, HID universal serial bus interface, and non-volatile memory. The O-Q cover is disposed in proximity to the diffractive grating and is mechanically coupled to the optical coupling system in a way that seals the portion of the optical coupling system comprising the diffractive grating in order to protect the diffractive grating from environmental contamination. The adequate permeability of metabolites through both of the hydrogels of the diffractive ICL yields a safe implant for the cornea. One or more vibrating elements may be removably attached to the tops of the cantilever bolts andor to the sides of the form.
