Corneal inlays are tiny lenses or other optical devices inserted into the cornea to reshape the front surface of the eye to improve vision. Some of these devices resemble very small contact lenses.
Less frequently corneal inlays may be referred to as “corneal onlays”.
During the procedure the corneal inlays are implanted within the tissue of the cornea, right in front of your pupil. They are are placed under a flap of tissue or in a special pocket created with a laser.
This type of refractive surgery is less invasive than phakic IOL procedures which involve larger implantable lenses that are placed deeper in the eye, in front of or behind the pupil.
