Purpose: to describe the visual and topographical changes after accelerated corneal collagen cross-linking (ACXL) in keratoconus-affected eyes.Methods: a retrospective case series study was made. Clinical records of patients with keratoconus-affected eyes... see more

Introduction: Corneal ulcer is a leading cause of blindness worldwide. Many of these patients don’t respond to conventional treatment with topical agents. Collagen cross-linking (CXL) has been suggested to avoid complications requiring emergency keratopla... see more

Background: Keratoconus is a corneal dystrophy characterized by progressive thinning, conical shape of the cornea and irregular astigmatism. It is particularly insidious when it occurs in very young patients. Case: We report the case of a 10-year-old chil... see more

We report a case of late onset keratectasia after laser in situ keratomileusis (LASIK) and its quick reversal and stabilization after use of latanoprost and riboflavin/ultraviolet-A corneal collagen cross-linking (CXL). A 39-year-old man with normal intra... see more

Corneal collagen cross-linking increases the stability of the cornea through the use of the photosensitive material - riboflavin (vitamin B2) and ultraviolet A radiation. Progressive keratoconus is the most common indication and the frequency of these pro... see more

The polymeric biomaterial film based on poly(vinyl alcohol) (PVA) and fish collagen of Lates calcarifer scale were synthesized by three times freeze-thaw cycles followed by gamma irradiation at varied doses of 0, 10, 20, and 30 kGy respectively. Character... see more

Collagen films were produced from five commercial collagen dispersions used for in-line sausage co-extrusion production. Films were prepared by partially dehydrating in a salt solution (30%) and crossed linked with smoke condensate (15%) or glutaraldehyde... see more

This study aims to determine the functional properties of natural and modified sago starch as a substitute for raw material for capsule shells from animal gelatin. Rumbia starch (Metroxylon sagu Rottb) or sago starch has good biodegradability, edibility, ... see more

Gelatin is a proteinaceous substance composed of all the essential amino acids (except tryptophan) and derived from collagen using a hydrolysis technique. Hydrogels and modified composites based on gelatin are widely used in the food industry, biomedicine... see more
