\nPhakic intra-ocular lenses like ARTISAN<\/a>, ARTIFLEX<\/a>, VISIAN ICL<\/a> and TORIC VISIAN ICL are possible after stabilization of keratoconus by Corneal cross-linking with or without Intra Corneal Rings to treat myopia and residual astigmatism.<\/p>\n
\n It’s the last solution for keratoconus in case of no-stabilization and failure of other techniques like rigid contact lenses, cross-linking or intra-ocular lenses and intra-corneal rings.<\/p>\n
\n Deep lamellar or penetrating keratoplasty need sutures on the cornea at the end of the surgery. Sutures can be removed only after one year. Residual myopia and astigmatism after the removal of the sutures can be treated by Lasik and if they are very high, by Phakic intra-ocular lenses: ARTISAN<\/a>, ARTIFLEX<\/a>, or TORIC ICL<\/a>.<\/p>\n
