Central Corneal Regularization (CCR)
Central Corneal Regularization is where the patient’s cornea is reshaped by the fastest laser 1000 Hz and then cross-linking is done to arrest the Keratoconus. The principle of CCR is to reshape the cornea and make the Keratoconus cone slightly flat and irregular. In CCR, the surgeon treats the Keratoconus cone by shifting the cone in the centre. This is achieved by performing laser on the side of the cornea which is thicker, therefore, not damaging the cornea that is already thin. The sight can be improved by giving proper prescription of the glasses or contact lenses or cross-linking procedure which helps arrest the Keratoconus and stiffens the cornea.
What is done?
In CCR, the top of the cone is reshaped and flattened and the rest of the cornea is sculpted to bring it to its original shape.
How is it done?
IVIS technology has a unique platform. With high precision tomography, after analyzing nearly 39,000 spots on the cornea, an original defect especially in the central part of the cornea is identified, considering that Keratoconus is in the central area. With 1000 Hz frequency, IVIS laser will reshape the top of the cone and the surrounding area. This is done by putting local anaesthetic drops and the procedure takes only about 40 seconds!
CCR is done by Excimer laser and is not a refractive procedure. The principle is to reduce the irregular astigmatism to regular astigmatism, and to reshape the cornea so that glasses or contact lenses can be prescribed.
