Indications for Contact Lenses or Keratoplasty in Keratoconus

Lamellar Keratoplasty in Corneal Ectasias

“…Also, this represents a valuable improvement in relation to the pre-operativ condition; none of the cases of keratoconus operated by us possessed comparable vision without correction before operation. 'The keratoconic patient is tremendously handicapped if he is without his contact lenses' [2]. In 69 of the 70 eyes operated, correction with spectacles have better vision.…”

Lamellar Keratoplasty in Corneal Ectasias

“…Therefore, in this new revision we intend to include the following: keratoconus secondary to vernal catarrh [3], ectasias secondary to parenchymatous keratitis and also keratolorus. Primary keratoglobus, probably a spon taneous clinical variety of keratoconus and secondary kerato globus following the use for many years of scleral contact lens [4,5] for an earlier keratoconus are also included in this series.In any case, although we know that some of the different types of ectasias can, under some circumstances, change the time for surgery, some stage of the operation, or even the result, we believe that as from now keratoconus can be accepted as a pattern for these corneal deformities. A discussion of these deformities is the reason for our paper.…”
