The study was designed with the intention of reducing the risk of complications in extended wear. 214 eyes were fitted with Scanlens 75 high water content lenses for extended wear and followed for one year. The first 100 eyes to pass the 1‐year check‐up successfully were then followed for another year. The lenses used are high in oxygen transmissibility and at the same time rigid enough to allow good movements, which are considered very important. Thorough patient information, flat fits, frequent check‐ups, and frequent lens replacements were principles applied to prevent discomfort and complications. Visual acuity and comfort were very good. Discomfort and unfavourable Findings were low in frequency and healed without any sequelae whatsoever. The success rate was as good as 94.9% at 6 months, 92.1% at 1 year, and 88.4% at 2 years. The favourable results are considered to be due to the type of lens used as well as to the principles employed.
