Methods A retrospective analysis was made on 17 cases (17 eyes) of bullous keratopathy which were treated by penetrating keratoplasty or combined surgery.The follow up period was 2 to 43 months. Results The grafts of 12 cases were transparent,3 cases were semitransparent,2 cases were opacificative.Only 4 cases suffered from immune rejection 2 weeks to 21 months postoperatively. The immune rejections were controlled by conservative therapy. All of the patients with intolerable pain preoperatively became pain free postoperatively.Only one case of blindness before operation did not change after operation.
