Corneal tissue changes following short-term soft contact lens wear of different materials.

ABSTRACT:

Purpose

To study the effect of different soft contact lens (CL) materials during short-term wear on corneal tissue.

Methods

Twenty-two healthy participants wore both silicone hydrogel (MyDay, CooperVision) and hydrogel soft CLs (Biomedics 1 day extra, CooperVision) for 8 h per lens. In each session, Scheimpflug images were captured before and immediately after CL removal. Images were analysed using the densitometry distribution analysis, a technique from which two parameters, α (corneal transparency) and β (corneal homogeneity), were estimated. In addition, the central corneal thickness changes after CL wear and the influence of the CL material on corneal transparency were evaluated.

Results

The β parameter (homogeneity) increased by 5% after wearing both CL materials
