Method of manufacturing a pair of contact lenses for improving visual performance in patients with keratoconus as well as a set of passive lenses.

摘要

In a method of manufacturing a pair of contact lenses for improving visual performance in patients with keratoconus corrected with hard or soft contact lenses, use is made of a set of rotationally stabilized passive lenses with different frontal optics, one at the bottom of the passive segment has a more positive and negative strength than the other part of the front-end. First, what eye of the patient has the lowest degree of keratoconus. Then, for that purpose, the most effective passports can best be seen from the set of passive lenses by using different passes of the set of pass lenses one by one with this best eye while the patient looks at optotypes with both eyes . Then this is repeated for the other eye of the patient. Spherical pass glasses are then held with different strength for each eye to determine the base strength of the contact lenses to be manufactured. After that, a contact lens is manufactured for each eye with a strength equal to that of the passport found and has a segment with a strength equal to the sum of the strength of the segment of the selected passport and the strength of the passport.
