collagen cross-linking
patients with keratoconus constitute a large proportion of patients suffering from anterior segment disorders. as of this time, however, its pathogenesis has not yet been elucidated. a reduction in cross-link between collagen molecules has been observed in keratoconic eyes as compared to normal ones. present approaches only address refractive errors resulting from the abnormal abnormal corneal ...
متن کاملChemistry of collagen cross-links: glucose-mediated covalent cross-linking of type-IV collagen in lens capsules.
The incubation of lens capsules with glucose in vitro resulted in changes in the mechanical and thermal properties of type-IV collagen consistent with increased cross-linking. Differential scanning calorimetry (d.s.c.) of fresh lens capsules showed two major peaks at melting temperatures Tm 1 and Tm 2 at approx. 54 degrees C and 90 degrees C, which can be attributed to the denaturation of the t...
متن کاملHistopathological Finding of Cornea after Collagen Cross-Linking Using Riboflavin and Ultraviolet A in Rabbit
Purpose: To evaluate the histopathological changes of the cornea in rabbit corneas after accelerated collagen cross-linking. Methods: Right eyes of 7 adult New Zealand albino rabbits weighing 1.5 to 2.0 kg were studied. Right eyes of all animals were in the treatment group and left eyes were in the control group. The epithelium of all right eyes was removed and was crossed-linked with riboflavi...
متن کاملStandard versus trans-epithelial collagen cross-linking in keratoconus patients suitable for standard collagen cross-linking
PURPOSE Evaluating the clinical results of trans-epithelial collagen cross-linking (CXL) and standard CXL in patients with progressive keratoconus. METHODS This prospective study comprised 20 eyes of 20 patients with progressive keratoconus. Ten eyes were treated by standard CXL and ten by trans-epithelial cross-linking (TE-CXL, epithelium on) with 1 year of follow-up. All patients underwent ...
متن کاملCorneal collagen cross-linking procedures
Objective: to present corneal collagen corsslinking techniques. Corneal collagen cross-linking (CXL) is a procedure used to slow down or arrest the progression of keratoconus in order to avoid or, at least delay the necessity of keratoplasty. CXL means photopolimerisation of the stromal fibrillar tissue, in order to increase their stiffness and resistance to the corneal ectasia. CXL is a proces...
