Purpose. Evaluation of the indications, anatomical and functional results, and complications of total penetrating keratoplasty (TPK)
in disorders involving whole cornea. Materials and Methods. We analyzed outcomes of the surgical treatment of 47 eyes of 46
patients that underwent TPK. Indications were infectious keratitis, autoimmune disease, injury of the eyeball (mainly chemical
burns), and other combined disorders. The surgical technique involved dissection of affected tissues with a margin of 1.0 mm.
The size of the corneal graft ranged from 10.0 to 14.0 mm. We analyzed indications, outcomes, and complications of surgery.
Results. Final restoration of the ocular integrity and maintenance of the globe were achieved in 27 eyes (57%). More than one
surgery was necessary in a total of 29 eyes (62%). The frequency of retransplantations did not vary significantly between the
groups with different causes of corneal melting/perforation (63% of eyes with infection, 66% of eyes after trauma and 70% of
eyes of patients with autoimmune disorders). Surgical treatment failed in 20 eyes (43%). Evisceration was necessary in 13 eyes
(28%), phthisis occurred in 7 cases (15%). Conclusion. TPK should be considered as a last line treatment in huge corneal
destruction to restore integrity of the eye globe.
1. Introduction
Serious corneal disorders like ulcers or perforations
frequently give rise to difficult clinical situations, with rapid
consecutive threatening of vision and disintegrity of the eye
globe. Despite current advances in pharmacological and
surgical treatment, severe corneal infections, injuries, or
systemic diseases can lead to corneal perforations, which
frequently require surgery “à chaud.”
Urgent reconstructive surgical interventions may be nec-
essary to avoid consecutive endophthalmitis and the forma-
tion of the anterior and posterior synechiae and secondary
glaucoma and to prevent the spread of pathogens toward
the posterior pole of the eye globe or to avoid other severe
complications [1–4]. The optical result of urgent surgical
treatment is less important; if possible, visual restoration or
rehabilitation may be accomplished in the future. Initial dif-
ficult and complicated medical status, despite a wide spec-
trum of pharmacological and surgical treatments, may
result in fatal treatment failure with loss of the eye. The poor
visual outcome of rapid corneal surgery may require further
surgery [1, 4–6].
The surgical approach to retain corneal integrity may
vary, depending on size, localization, depth of corneal tissue
damage, and the state of other internal globe tissues. Also,
coexistent or causative infection or inflammation may deter-
mine the choice and timing of surgical decisions. Additional
surgical procedures like amniotic membrane transplants,
