Initial comfort and surface wettability: a comparison between different contact lens materials.

A clinical investigation was performed to compare the initial comfort and surface wettability of the Novalens (Ocu-Tec), ENVISION (Polymer Technology Corporation) and D3X4 (Wesley-Jessen). Fifteen subjects were randomly fit with each one of these three lens materials. Initial comfort was significantly better with the D3X4 lens; no significant difference was found between the two rigid lens materials. No significant difference in lens surface wettability was found between the three materials.
