The whole of the Friday morning session was given over to silicone hydrogels and the lessons learnt over the 10 years since their introduction. Chaired by the always entertaining Professor Brien Holden, speakers included Professor Fiona Stapleton who re-emphasised some of her research findings concerning inflammatory events and the impact of silicone hydrogel material upon the incidence of microbial keratitis.
Far from seeing the end of this potentially sight-threatening condition, Stapleton suggested that the improvement was less than clear cut. Data looking at extended wear modalities suggested that there may well be higher rates of infiltrates in silicone hydrogels (SiH) compared to conventional hydrogels, though the data may fail to suggest that the infiltrates may well be of a different aetiology or tend to be less severe. Furthermore, it appears to be the case that the risk of infiltrates is greatest in the early period of continuous wear with SiH lenses.
