ABSTRACT
The indications and the adaptation method of a combined contactoptical system called piggy-back system, are dealt with.

The optical and the therapeutic results obtained in 7 groups of patients (56 eyes) with astigmatism, aphakia, keratokonus, keratoplasty, injuries, chronic lesions of the epithelium, and hyposecretion of the tear fluid, are discussed together with the results of the adaptation of the lenses.
