The impact of modern soft contact lens wear on corneal curvature and thickness and on the outcomes of refractive Laser surgery

The research will evaluate the impact of modern soft contact lens (SCL) wear on corneal curvature and thickness parameters. The stability of these measurements following SCL cessation for a two week period will be examined. Through comparison of curvature and thickness scans between a group of SCL wearers and a non-lens wearing control group, the influence of SCL on corneal measurements will be analysed.


The accuracy of pre-operative measurements of corneal curvature and thickness is crucial in order to assess patient suitability for corneal refractive surgery (CRS) and rule out potential risk factors for developing post-operative corneal ectasia. SCL wear may impact on the stability of these measurements and result in poorer CRS outcomes. This study will assess the stability of measurements taken prior to CRS and the possible influence of SCL wear on refractive outcomes.
