[Thin soft hydrogel lenses of high and low water (author's transl)].

The authors relate the results obtained with very thin soft hydrogel lenses (0,10 mm thickness) of high and low water content: the Vergo-Softcon THX of 70% water-content and the Bauch and Lomb Plano-T of 38%. The most frequent indications encountered are bullous keratopathy, epithelial defects and keratitis sicca. The results are positive in 78,2% of cases with 70% w/c soft hydrogel lenses. Results are given for cases of direct fitting of thin lenses, as well as for cases of fitting after failures of classic soft hydrogel lenses and in cases of exchanges of 40% lenses for 70% lenses. The 70% water content lenses seem to give better results main in cases of epithelial defects and keratitis sicca.
