OBJECTIVE: Postoperative corneal assessment after using two different types of crosslinking equipment METHODS: Two groups of patients, group A with 36 eyes, and group B with 19 eyes, were submitted to the treatment for the stabilization of keractoconus by corneal collagen crosslinking. In group A the equipment used was Crosslink (IROC – Germany), while in group B the equipment was used was Xlink (Opto – Brazil). RESULTS: Corneal reepithelization time, visual acuity, biomicroscopy, topography, corneal tomography and specular microscopy were […]

The cornea has a great influence in the visual process. However, it is liable to distortion, such as flattening. When this flattening is caused by the use of contact lenses, we call “corneal warpage”. In this case, some symptoms may occur as blurred vision with glasses, conjunctival hyperemia, foreign body sensation, etc… Used to think that the cornea was more rigid and, in time, realized that the cornea has viscoelastic properties. We can say that the cornea has a body […]

PURPOSE: Assess the clinical and topographical effects of corneal collagen crosslinking in patients with keratoconus on Brazilian population. METHODS: Thirty seven eyes of 37 patients (22 female and 15 male) with diagnosis of progressive keratoconus and corneal paquimetry higher than 395 micra, were treated with riboflavin and ultraviolet A radiation, over 30 minutes, to induce corneal collagen crosslinking. Keratometric values were compared as well as the best corrected visual acuity, before and after the procedure, with ranges of 40 and […]
