KAMRA Inlay (“inlay”) is a dark, ring-shaped device that is implanted in the cornea, which is the clear, front surface of the eye. The inlay improves near vision in patients whose eyes have lost the ability to change focus for near vision, which is a normal part of aging (presbyopia). The device is 3.8 mm in diameter with a 1.6 mm diameter hole in the center. It has 8,400 tiny holes to allow oxygen and nutrients to flow across the cornea.
How does it work? The eye surgeon uses a laser to make a pocket-shaped cut in the cornea to implant the device. The device works by blocking unfocused light rays entering the eye resulting in improved near vision.
When is it used? The inlay is placed in the non-dominant eye of patients:
- Between the ages of 45 and 60 years old.
- Who have not had cataract surgery.
- Who are unable to focus clearly on near objects or small print.
- Who do not need glasses or contact lenses for clear distance vision.
- Who need reading glasses with +1.00 to +2.50 diopters of power.
What will it accomplish? The inlay is intended to improve near vision when used in patients as described above.
When should it not be used? You should not have the inlay implanted if:
- You have severe dry eye.
- You have an active eye infection or inflammation.
- You have signs of a condition resulting in corneal thinning and a cone-shaped bulge in the center of the cornea, or other abnormalities related to the shape and/or surface of your eye.
- You do not have enough corneal thickness to safely have the procedure performed.
- You have a recent or recurring herpes eye infection or problems resulting from past infection.
- You have uncontrolled glaucoma.
- You have uncontrolled diabetes.
- You have an active autoimmune or connective tissue disease such as lupus (systemic lupus erythematosus or SLE) or rheumatoid arthritis.
