Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Transplantation Immunology

Background:

  • Penetrating keratoplasty (PK) was the standard for corneal transplantation for over 100 years.
  • Advancements in surgical techniques and instrumentation enable partial-thickness corneal transplantation.
  • Lamellar keratoplasty techniques are emerging as alternatives to full-thickness PK.

Purpose of the Study:

  • To review the indications for both penetrating and lamellar keratoplasty.
  • To compare the advantages and disadvantages of these corneal transplantation methods.
  • To highlight the shift towards component transplantation in corneal surgery.

Main Methods:

  • Review of current literature on penetrating and lamellar keratoplasty techniques.
  • Comparative analysis of surgical outcomes, including endothelial failure rates and visual rehabilitation.
  • Discussion of immunological aspects and patient selection for each procedure.

Main Results:

  • Lamellar keratoplasty may offer reduced rates of endothelial failure due to immunological rejection compared to PK.
  • Faster visual rehabilitation is a potential advantage of lamellar techniques.
  • The choice of technique depends on specific indications and desired outcomes.

Conclusions:

  • Lamellar keratoplasty represents a significant advancement in corneal transplantation.
  • Component surgery offers benefits such as improved graft survival and quicker visual recovery.
  • Understanding the indications and comparative outcomes is crucial for selecting the optimal transplantation method.
