[Permanent-wear of gas-permeable rigid lenses: a new solution for the aphakic patient].

The authors reviews his experience during a period of six years with permanent wear gas-permeable hard contact lenses. Problems with dislocation of the lens during sleep was solved by using a diameter of 11 mm. Corneal respiration was maintained due to the oxygen permeability of the new material. A new fitting technique was developed advising daily wear for 8 days post-operatively, extended wear at the 15th day, and the final lens given after 45 days. The results obtained suggests that the technique is a very real alternative to intraocular lens implantation.
