Selecting patients for penetrating keratoplasty

Area of Science:

• Ophthalmology
• Corneal Surgery
• Transplantation Science

Background:

• Penetrating keratoplasty (PKP) is a corneal transplant procedure.
• Patient selection is crucial for successful PKP outcomes.
• Several factors influence graft survival and visual recovery.

Purpose of the Study:

• To outline the critical factors for selecting appropriate patients for penetrating keratoplasty.
• To emphasize the multifaceted nature of successful corneal transplantation.

Main Methods:

• Review of established criteria for patient selection in corneal transplantation.
• Analysis of pre-operative, intra-operative, and post-operative considerations.
• Identification of four key domains influencing graft success.

Main Results:

• Successful PKP depends on four primary factors: psychosocial assessment, general ocular health, host cornea structure, and surgeon's skill.
• Psychosocial factors include visual needs and patient's capacity for long-term graft care.
• Ocular health encompasses surface integrity, intraocular pressure, motility, and absence of vitreoretinal disease.

Conclusions:

• Comprehensive patient evaluation across psychosocial, ocular, corneal, and surgical domains is essential for successful penetrating keratoplasty.
• Thorough preoperative assessment and skilled postoperative management by the ophthalmologist are vital.
• Optimizing these factors enhances graft survival and visual prognosis in corneal transplant recipients.
