[Clinical observations on the combined operation of penetrating keratoplasty, extracapsular cataract extraction and IOL implantation].

26 cases of cataract complicated with corneal leukoma were performed penetrating keratoplasty in combination with extracapsular extraction and IOL implantation. In a follow-up of 6-31 months, the corneal grafts were transparent in 16 eyes(62%), semi-transparent in 7 eyes(27%), and opaque in 3 eyes (11%). Useful vision was restored to 18 eyes (69%). The combined operation is believed to be the best choice in treatment for such cases.
