Kerarings also called 'corneal implants' or 'intra-corneal ring segments' are a surgical treatment for keratoconus. The small, clear semi-circular rings are inserted at the edge of the cornea. They flatten the distorted cone shape of the cornea returning it to a more normal curve, improving vision so glasses and/or contact lenses are easier to tolerate.

Surgery

Keraring surgery is done as an outpatient day surgery, taking around 30 minutes and you will be awake during the procedure. Dr Reece Hall will use the femtosecond laser to make a tiny, precise circular channel within your cornea. Your corneal implants (kerarings) will then be carefully inserted into the channel and the incision will close and heal naturally, without the need for stitches.

Results

Kerarings are a very safe procedure as no corneal tissue is removed. Most people can return to day to day activities in 2-3 days. You will most likely notice an immediate improvement in your vision after keraring surgery, but we advise you to let your vision settle for around three months before being fitted for new glasses or contacts.
