Penetrating keratoplasty with optical aims. Presentation of four cases
Keywords:
penetrant keratoplasty, corneal opacity, visual acuity.Abstract
Penetrating keratoplasty has been a procedure used, almost universally, to treat corneal diseases affecting vision in an irreversible way. Four clinical cases are reported of patients with corneal affections severely compromising vision, given by short vision and luminous perception. After completely evaluating each case, the authors decided to perform the penetrant keratoplasty with optical aims, to recover cornea transparency and the vision quality. There were not transurgical complications and the patients were followed up according to the protocols of post-surgery evaluation of corneal graft. The results and evaluation were satisfactory; after a year, the transparency of the graft was maintained and visual acuity substantially improved.
