Corneal Inlay
A corneal inlay (also called an intracorneal implant) is a device which is surgically implanted in the cornea of the eye as a treatment for presbyopia. Successful installation results in reducing dependence on reading glasses, so that the user can more easily engage in everyday tasks such as using a mobile phone, reading store shelf prices and working on a computer.
Coreal inlays are small, thin, and permeable. Typically one is implanted in the non-dominant eye.
The Procedure
The inlays are implanted into the cornea either in a laser-created corneal pocket or lamellar corneal flap (similar to LASIK). The inlays can be removed should the patient develop another condition requiring medical treatment.
The procedure takes less than 15 minutes and can be performed in the eye surgeon's office. Sutures are not required, and only topical anesthesia in the form of eye drops is used.
Corneal Inlay Types
The KAMRAinlay (AcuFocus, Inc.) is a biocompatible ring that increases the visual depth of field using the physical principle of a small aperture. This design only allows focused light to enter the eye resulting in an improvement in near and intermediate vision while maintaining distance vision.
The Raindrop Near Vision Inlay (also known as Vue+ and Presbylens) (Revision Optics, Inc.) is a micro-porous hydrogel inlay that creates a microscopic change to the curvature in the center of the cornea, resulting in a multifocal cornea designed to support near and intermediate focusing power.
