Abstract

Objective To explore the corneal biomechanical characteristics change in cataractous eyes before and after phacoemulsification using corneal visualization Scheimpflug technology (Corvis ST) and evaluate the influence of 3 mm clear corneal incision on corneal biomechanics. Methods A self-control study was performed.Thirty-six eyes of 36 patients who received phacoemulsification were enrolled in Tianjin Eye Hospital from March to May 2015.The first/second applanation time, the first/second applanation length, the first/second applanation velocity, the highest concavity time, the highest concavity radius, peak distance(PD), deformation amplitude (DA), intraocular pressure, corrected intraocular pressure and central corneal thickness(CCT) were measured in preoperation, postoperative 1 week and postoperative 1 month.This study protocal was approved by Ethic Committee of Tianjin Eye Hospital, and written informed consent was obtained from each patient prior to any medical examination. Results The first/second applanation length, intraocular pressure, corrected intraocular pressure, PD, DA and CCT were significantly different among preoperation, postoperative 1 week and postoperative 1 month (F=3.42, 5.24, 4.21, 3.82, 3.91, 4.03, 3.62; all at P 0.05). Conclusions Corneal biomechanical properties occur change in the early stage after phacoemulsification and return to normal in postoperative 1 month . Key words: Corneal biomechanics; Cataract/surgery; Phacoemulsification; Corneal visualization Scheimpflug technology
