Summary

Pseudophakic penetrating keratoplasty offers good vision restoration for bullous keratopathy after intraocular lens (IOL) implantation. Most vision improvements are not limited by transplant rejection, but by extracorneal factors like cystoid maculopathy.

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Intraocular Lens Implantation

Context:

  • Bullous keratopathy is a common cause of corneal opacity following intraocular lens (IOL) implantation.
  • Pseudophakic penetrating keratoplasty (PKP) is a surgical option for visual rehabilitation in these cases.
  • This study retrospectively analyzes outcomes of PKP in eyes with pre-existing IOLs.

Purpose:

  • To evaluate the efficacy and safety of pseudophakic penetrating keratoplasty.
  • To assess visual outcomes and complications in patients with bullous keratopathy and prior IOL implantation.
  • To identify factors influencing visual prognosis after PKP in this specific patient group.

Summary:

  • 50 eyes with bullous keratopathy and prior IOL implantation underwent PKP.

  • Visual acuity improved in 44 eyes; 10 had vision limited by cystoid maculopathy (CMP).
  • No corneal graft rejection occurred; complications included wound dehiscence and other postoperative issues.

    • Impact:

    • Pseudophakic PKP demonstrates a favorable prognosis for visual recovery in bullous keratopathy.
    • Extracorneal factors, particularly CMP, are significant determinants of final visual acuity.
    • This research informs surgical decision-making and patient counseling for corneal transplantation in pseudophakic eyes.
