How Astigmatism Influences Corneal Biomechanics and Intraocular Pressure

Medical University of Lodz39 enrolled

Overview

The aim of the study was to identify whether preoperative corneal astigmatism can influence corneal biomechanics and the assessment of intraocular pressure (IOP) following micro-incision phacoemulsification.

Corneal Astigmatism Intraocular Pressure Cataract Senile

Interventions

non-contact measurement of intraocular pressureDIAGNOSTIC_TEST

Non-contact measurement of corneal biomechanical properties and intraocular pressure with an Ocular Response Analyzer. Parameters measured: corneal hysteresis (CH), corneal resistance factor (CRF), Goldman-correlated IOP (IOPg), corneal compensated IOP (IOPcc) and waveform score (WS).
