N2  - Purpose To evaluate the Goldmannapplanation tonometer (GAT) and the ocular response analyzer (ORA) tonometer in measuring intraocular pressure (IOP) in keratoconic eyes and eyes with post lasikectasia before and after riboflavin/ultraviolet A corneal collagen crosslinking (CXL), to assess agreement among devices and to analyze the impact of some ocular parameters on their measurements.  Patients and Methods  This prospective non comparative study included thirty eyes of 17 patients who had undergone corneal collagen crosslinking (CXL) to arrest progression of keratoconus or post LASIK ectasia. Intraocular pressure readings were taken by Goldmannapplanation tonometer and Ocular ResponseAnalyzer. The IOP was measured by the two techniques before the procedure of CXL and again 1 week, 1 month and 3 months after the procedure.Three reliable measurements were obtained from each eye and the mean was taken each time. Other changes were also analyzed before and after the CXL; such as central corneal thickness, corneal resistance factor and cornealhysteresis
