Corneal ring segments

Corneal ring segments

Corneal ring segments are used in treating keratoconus to improve the corneal irregularity and improve vision. The corneal ring segment evens out the shape of the cornea improving both corrected and uncorrected vision. The corneal ring segments are 1mm thick, clear curved crescents of plastic.

The 10-minute procedure uses a Femtosecond laser to create a 1mm circular channel within the cornea. The corneal ring segment is then introduced into this channel through a 1 mm incision. Recovery is next day, with vision continuing to improve over several months.
