The development of the applications of ocular response analyzer in excimer laser surgery

Abstract

Research on the application of ocular response analyzer has become one of the main issues in ophthalmology.The ocular response analyzer has been used in the measurement of ocular bioparameters of glaucoma,cataract,heretability and refractive surgery.As a newly invented non-contact tonometric device,the ocular response analyzer is helpful not only in the measurement of intraocular pressure (IOP),but also in the determination and calculation of two corneal biomechanical properties:corneal hysteresis (CH) and corneal resistance factor (CRF).It offers the possibility of measuring corneal biomechanical properties in vivo.This article primarily reviewed the application of the ocular response analyzer in terms of pre-operative examination and post-operative follow-up in excimer laser surgery. Key words: ocular response analyzer; excimer laser surgery; intraocular pressure; biomechanics
