Ferrara Ring Surgery

Ferrara rings surgery is A type of ring used to add to the corneal layer. The intrastromal corneal ring segment is made of polymethyl methacrylate, which is the same material used to produce artificial eye lenses for cataract surgery. Ferrara ring insertion surgery was initiated by Dr. Paula Ferrara and in 1996 using the principle that any volume enhancement in the outer cornea will reduce or flatten the curvature of the middle cornea, resulting in a corneal with abnormal curvature caused by certain eye diseases to have a reduced curvature and a more uniform curve. As a result, myopia and astigmatism decrease. Patients will be able to see better with the naked eye.

Corneal bulge or keratoconus is a condition in which the cornea is abnormal because the cornea originally had a curved shape similar to a dome, but instead bulged forward or cone-shaped. This is caused by the thinning of the cornea in the middle, causing pressure inside the eyeball, pushing the thinner part of the cornea to bulge out in front. Patients with corneal bulges will have poor vision. This syndrome also requires treatment. Ferrara Ring Surgery

Highlights of Ferrara Ring Surgery

• The structure of the cornea is strengthened. Reduce myopia and astigmatism Slowing down or stopping the course of the disease
• It is a minor surgery that does not pass through the middle of the cornea. The visual axis keeps the cornea in the center of the cornea clear as before.
• It is a surgery that inserts the ring into the corneal layer. It does not go into the eyeball and does not have surgery to remove the corneal tissue, so it is a small surgery with high safety.
• The ring can be surgically removed and corrected to return to the way it was before surgery. But it can usually be safely inserted throughout the day without removal.
• Adjustable procedure
• The surgery does not require anesthesia. There are no stitches and no need to stay in the hospital.
• The surgical incision is only 1 millimeter small, making the wound heal very quickly and recover shortly.
