Lens replacement habits in soft contact lens wearers.

The aim of this paper was to assess soft contact lens replacement habits of patients of Contact Lens Clinic, Zagreb University Hospital Department of Ophthalmology, Zagreb, Croatia. During spring of 2010, a survey was conducted in Contact Lens Laboratory, Zagreb University Hospital Department of Ophthalmology, Zagreb, Croatia. 47 completed surveys were collected and analyzed. The results of the survey have shown that the majority of soft contact lens wearers wear them longer than recommended by the manufacturer. It also showed that they eventually replace the lenses in regular intervals, indicating that they base their lens replacement on constant criteria. The main reasons for the eventual lens replacement were increased blur or discomfort while wearing lenses. Since it is obviously impossible to convince all lens wearers to replace their lenses as recommended by the manufacturer, it is up to the contact lens practitioners to find the way to reduce the risks of lens overwear. It may be achieved by introducing a method that will enable each soft contact lens wearer to choose an optimal lens replacement regimen without risking their eye health.
