title: [The first stage of clinical trials of hydrogel lenses manufactured in Czechoslovakia].
abstract: The authors give an account of the results of the first stage of clinical trials of Czechoslovak disc-shaped hydrogel lenses made from the copolymer HEMA and methacrylic acid. Hitherto assembled experience provided evidence that the envelope technique for opening of the anterior capsule does not ensure sufficient stability of these lenses in the later stage and their decentration may cause serious complications. Therefore the optimal solution is to place the implant in the capsule after circular capsulorhexy. Improvement of the geometrical and optic properties of the lenses during the subsequent follow-up and their perfect harmony with the surgical technique will produce even better functional results in operated patients.
