Glaucoma is the second cause of irreversible blindness in world. Intraocular pressure (IOP) a recognized major risk factor for development and progression glaucomatous damage. Goldmann applanation tonometry (GAT) internationally accepted as gold standard measurement IOP. The purpose this study was to search correlations between corneal mechanical properties thickness by means vitro tests. IOP m...

purpose: to assess alterations in parameters measured by the ocular response analyzer (ora) after photorefractive keratectomy (prk) with or without 0.02% mitomycin c (mmc) in myopic eyes. methods: in 33 right eyes of 33 patients, iop was determined using the goldmann applanation tonometry (gat) before and 3 months after prk. corneal hysteresis (ch), corneal resistance factor (crf), goldmann-cor...

PURPOSE In recent years, the interest in corneal biomechanics has strongly increased. The material properties of the cornea determine its shape and therefore play an important role in corneal ectasia and related pathologies. This review addresses the molecular origin of biomechanical properties, models for their description, methods for their characterisation, techniques for their modification,...

Any trauma can trigger a cascade of responses in tissues, with the purpose of safeguarding the integrity of the organ affected by the trauma and of preventing possible damage to nearby organs. Subsequently, the body tries to restore the function of the organ affected. The introduction of the excimer laser for keratorefractive surgery has changed the treatment landscape for correcting refractive...

Dear Editor: Changes in the biomechanical properties of the human cornea play an important role in the pathogenesis of corneal dystrophies such as pellucid marginal corneal degeneration and keratoconus. The latter primarily affects young people and is a leading cause of severe visual impairment. Keratoconus is characterized by weakened corneal biomechanics that leads to progressive bulging and ...
