The prognosis of penetrating keratoplasty based upon corneal morphology.

In this paper, the author has attempted to express the prognosis for successful penetrating keratoplasty based upon a morphological classification of corneal disease. Four groups have been designated with their basic prognosis ranging from excellent to poor. The importance of appraising the diseased cornea in the area of its optimal recipient zone has been stressed. Ancillary factors adversely affecting the estimated final prognosis of keratoplasty have been considered, with emphasis upon the importance of glaucoma, lid function, tear film, ocular inflammation and patient compliance. Not only is it important for the surgeon to appraise the chance of successful surgery, but it is essential for the patient to be informed in advance regarding the probability for successful surgery and the need to comply with sometimes demanding requirements of postoperative care.
