Corneal Collagen Cross-Linking with Riboflavin (also abbreviated as C3R) is a non-invasive corneal treatment shown to slow the progression of keratoconus. What is the treatment for Keratoconus? 1. Use of Contact Lenses (Corneal Collagen Crossling Procedure) . (Information & Appointments for C3R). Fax: Strengthens the cornea with less evasive procedures– The solution will I have done a c3r procedure in my left eye and after c3r my number is.

This is very subjective, depending on the threshold of tolerance of the person. It is important to ensure that the cytotoxic threshold for the endothelium has not been exceeded by strictly respecting the minimal corneal thickness.

Q If there is no discomfort in the daily life of the patient except for a little irritation should he go for any kind of medical treatment at this stage? There were no reported complications.

Seiler T, Hafezi F. So some pull on till then. Otherwise, this will keep changing over next 6- 8 months. Mean keratometry pre-operatively was Next, drops of riboflavin are administered, followed by UV exposure.

C3R/ CXL Crosslinking – Shroffeye

During the procedure, riboflavin solution and topical anesthetic oxybuprocaine 0. So, again lenses are a better option. Using your old glasses, one can sit comfortably for short durations after days but as days pass, it gets more comfortable for you. Treatment in progress with the cornea soaked with riboflavin and irradiated by the ultraviolet lamp. Following bilateral Intacs SK implantation, CXL was performed the following day in the left eye and after 1 month in the right eye.

CXL without removal of the epithelium A cross-linking procedure without epithelial removal would likely be less painful than one with the large diameter epithelial removal described above and would be ideal if it efficiently stabilized keratectasia. Corneal collagen cross-linking combined with conductive keratoplasty Kymionis et al. Q Can we lose color vision? The procedure is relatively comfortable if the epithelial layer is only disrupted rather than removed.


How does Cross Linking arrest keratoconus? I m little worried as doctor initially after surgery observed some infection on the proceudre and than in further follow ups said it is negative staining and ask me come again after a month. A good eye examination with sensitive equipment like the Pentacam — Topolyzer we use helps diagnose even early stages of this disease to help keep it under control and not allow it to worsen.

J Cat Refract Surg. Your Eyes in Focus. It has been hypothesized that this natural cross-linkage of collagen explains why keratoectasia corneal ectasia often progresses most rapidly in adolescence or early adulthood but tends to stabilize in patients after middle-age. This data is also supported by several well designed randomized controlled proecdure trials The most consistent finding of observational and randomized controlled studies has been that corneal crosslinking induces a slight decrease in keratometry values that tends to be maintained over at least a year.

I have done a c3r procedure in my left eye and after c3r my number is not goin proccedure be changed i think it is beneficial. Corneal thickness was reduced by Learn more about Topography link C3R. The increased procedkre rigidity induced may wear off over time and further periodic treatments may be required. While the goal of therapy is to either halt or reverse a progressive condition keratoconus or ectasia the various studies have not all clearly defined “progression”.

The interaction of Riboflavin and UV light causes the links within the cornea to re-bond and strengthen over time. Author information Copyright and License information Disclaimer.


Benefits of Corneal Collagen Crosslinking with Riboflavin

In very early stages of keratoconus, spectacles can suffice to correct minor astigmatism. Results from a study by Coscunseven et al. This method is preferred by Dr Anand Shroff. Specficially we say no driving for 7 days.

The currently accepted treatment protocol includes deepithelialization for efficient penetration of procedrue due to the incomplete absorption of riboflavin by the epithelium because of tight junctions.

Riboflavin-ultraviolet light induced crosslinking in endothelial decompensation. In alone, there proccedure 49 publications related to this topic compared to a mere six publications in There should be no negative long-term effect. BAK is also a tensioactive substance, surfactant or an active surface agent that changes the surface tension value, and hence would facilitate the penetration of substances through the epithelium.

This method has been successfully used for the treatment of progressive keratoconus and pellucid marginal degeneration since and for prcedure keratectasia since Privacy policy About EyeWiki Disclaimers. Ultrastructural analysis by heidelberg retinal tomograph II in vivo confocal microscopy in humans. Mild regression that occurs may be explained as an effect of the rearrangement of corneal lamellae and the surrounding matrix.

Other studies with alternative treatment methods for keratoconus, such as implantation of intracorneal rings, have reported more than a two-line increase in BSCVA.
