Zusammenfassung:Highlights • Cornea deformation was investigated during Irrigation/Aspiration in Phacoemulsification. • Hyper elastic property of cornea and the thickness variation are included in the model. • Surge in the anterior chamber occurs in a negative gauge pressure. • Anterior chamber instability occurs at higher volume flow rates for coaxial system. • Deformation of the cornea is less for bimanual system.
