What is the success rate of C3R?

In over 53% of those eyes there was a slight reversal and flattening of the keratoconus by up to 2.87 diopters. Best corrected vision improved by 1.4 lines. This technique has shown great promise in treating early cases of the disease.

Does C3R improve vision?

While C3R treatment generally does not lead to significant improvement in the inherent vision of the eye, however, as the corneal curvature flattens and the surface stabilizes, the best corrected visual acuity with spectacles and contact lenses improves.

How long does C3R last?

The contact lens is removed 4-5 days after the epithelial healing is complete. Corneal haze develops in most cases following C3R/CXL. This resolves significantly over three weeks and completely over six months.

How many days rest after C3R?

The treated eye is usually painful for 3 to 5 days, however levels of discomfort vary from patient to patient. Recovery time is about one week although most patients may find that it may be slightly longer.

Is C3R a refractive surgery?

What is C3R? C3R eye surgery is a non-invasive treatment for Keratoconus in which the corneal tissues are strengthened to stabilise the vision in the early stages of the condition. C3R involves one-time application of riboflavin drops to the eyes. Riboflavin is activated with exposure to UV rays.

What should I do after C3R?

After the treatment, antibiotic eye drops are applied; a bandage contact lens may be applied, which will be removed by our doctor during the follow up visit. Protective eye wear, such as sunglasses (also given by us) is to be worn for a few days until complete healing takes place.

Is C3R refractive surgery?

Why C3R surgery is done?

Corneal Collagen Cross-Linking with Riboflavin (also abbreviated as C3R) is a non-invasive corneal treatment shown to slow the progression of keratoconus. It does so by increasing the strength of corneal tissue. Undergoing C3R in the early stages may help stabilize vision.

Can we do LASIK after C3R?

This abnormal bulging of the cornea may then be stopped by ‘C3R’ or what is called Collagen Cross-Linking. The importance of cornea screening is to detect sub-clinical or hidden Keratoconus, and reject these cases so that the rest of the eyes undergoing LASIK treatment are safe.

Can we watch TV after C3R surgery?

Day to day activities such as watching TV or using a computer will not do any damage to your eye, but you might find it more comfortable to rest with your eyes closed for the first few days. You will be given an appointment 1 day, 1 week and 1 month after the procedure to check the healing of your eye.

Can we do PRK after C3R?

Corneal Collagen Cross-linking with Riboflavin (C3R) with Topography Guided Laser Surface Treatment (C3R + Topo guided PRK) is a procedure that can be offered to those with early keratoconus. We now perform treatments which combine C3R with an excimer laser surface treatment.

What precaution should be taken after C3R treatment?

Precautions After C3R Surgery Use the eye drops prescribed by your doctor to keep your eyes well-lubricated. Maintain proper hygiene around your eyes and avoid rubbing or touching your eyes frequently. Avoid any heavy activities during the initial few days. Follow all the instructions given by your doctor carefully.

What is the C3R procedure?

C3R is designed to increase the number of cross-linkages between the collagen proteins and prevent the cornea from bulging out any further. During the C3R procedure, eye drops containing riboflavin are introduced to the cornea. After the cornea adequately absorbs the eye drops, ultraviolet light is placed over the eye.

What are the options after C3R treatment?

Secondly, once the C3R is done, we look at the refractive error 3 months to 6 months after the treatment and see if there is any aid to improve vision. The options include : spectacles, RGP contact lenses, special keratoconus contact lenses, laser, ICL’s etc.

Does C3R help in the correction of cataract?

C3R is not going to help any spectacle correction, but only stabilize the progression of the abnormality viz. keratoconus.

Can C3R be used to treat keratoconus?

The cornea in keratoconus cases is ‘wavy’ on the surface. So even if treated by C3R or crosslinking surgey, the basic “waviness” or irregular surface of the cornea does not get treated.
