What are Corneal Inlays?
Corneal inlays are mini-rings with an opening – or pinhole – in the center, which are surgically inserted into the cornea in order to improve near vision in older adults with presbyopia. This, in turn, can reduce the need for reading glasses.
As the name suggests, corneal inlays are placed within your cornea, as a separate procedure or in combination with iLASIK in a two-step procedure.
This method is stable and long-lasting; the inlay may halt the visual effects of presbyopia over the long-term. It restores near and intermediate vision while maintaining good distance vision, provides quality reading vision, maintains depth perception and is removable.

What is Kamra?
In 2012 Kamra, which was developed by AcuFocus, became the first corneal inlay to gain Health Canada approval.
The Kamra inlay is specifically designed to reduce or even eliminate the need for reading glasses amongst individuals between the ages of 45 and 60 who have good distance vision without glasses, but suffer from presbyopia, which affects their near vision.
The Kamra inlay is incredibly small and very thin. It has a diameter of 3.8 mm (which is about a quarter the size of a soft contact lens) and is only 6 microns thick, making it about one-tenth the thickness of the average human hair.
The inlay has an opaque outer ring and a tiny (1.6 mm) central opening. When the Kamra is implanted in your cornea it is positioned so that the central opening sits directly in front of your pupil. This creates a “pinhole camera” effect and expands your range of clear vision. It brings nearby objects into sharper focus while still maintaining clear distance vision.
You do not need a Kamra implanted in both eyes. Instead, the device is generally implanted in your non-dominant eye. This allows both of your eyes to see clearly at distance, while the Kamra improves your near vision.
The corneal inlay procedure takes less than fifteen minutes and can be performed at the Horizon Laser Vision Center. No stitches are needed for this procedure, and healing time may vary between patients.
