Corneal biomechanics in iatrogenic ectasia and keratoconus: A review of the literature
The Ocular Response Analyzer (ORA) (Reichert Ophthalmic Instruments, Buffalo, NY) allows direct measurement of corneal biomechanical properties. Since its introduction, many studies have sought to elucidate the clinical applications of corneal hysteresis (CH) and corneal resistance factor (CRF). More recently, detailed corneal deformation signal waveform analysis (WA) has potentially expanded t...
متن کاملCorneal Ectasia: prevention and management
Francois Malecaze MD commenced the session with an update on current research into the genetics of keratoconus. Dr Malecaze noted that forme fruste keratoconus is one of the major causes of post-LASIK corneal ectasia and the condition may be due to genetic factors in the majority of cases. Identification of the gene or genes responsible for keratoconus might lead to the development of blood tes...
متن کاملAirbag induced corneal ectasia.
PURPOSE To report a case of airbag induced corneal ectasia. METHODS Case report. RESULTS A patient 3 years post-LASIK developed bilateral corneal ectasia worse in the right eye following airbag deployment in a road traffic accident. At last follow up, best corrected vision was 20/40 with -4.00/-4.00 x 25 in the right eye and 20/25 with -1.25/-0.50 x 135 in the left eye. CONCLUSIONS This i...
متن کاملIntegration of Scheimpflug-Based Corneal Tomography and Biomechanical Assessments for Enhancing Ectasia Detection.
PURPOSE To present the Tomographic and Biomechanical Index (TBI), which combines Scheimpflugbased corneal tomography and biomechanics for enhancing ectasia detection. METHODS Patients from different continents were retrospectively studied. The normal group included 1 eye randomly selected from 480 patients with normal corneas and the keratoconus group included 1 eye randomly selected from 204...
متن کاملCollagenase-mediated tissue modeling of corneal ectasia and collagen cross-linking treatments.
PURPOSE Corneal collagen cross-linking (CXL) is a method for modifying the natural history of keratoconus and other corneal ectatic diseases. The authors evaluated the use of collagenase for generating an experimental model of ectasia to evaluate the topographic effects of CXL interventions. METHODS Nine human corneoscleral specimens unsuitable for transplantation were used. After epithelial ...
