Refractive results after corneal triple procedures (PK+ECCE+IOL)

Summary

Corneal triple procedures, including penetrating keratoplasty and cataract surgery, often resulted in hypermetropia and poor uncorrected vision. Biometry did not consistently improve refractive outcomes in this patient group.

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Refractive Surgery

Background:

  • Corneal transplantation is a common procedure for vision restoration.
  • Cataract surgery with intraocular lens (IOL) implantation is frequently combined with corneal procedures.
  • Assessing refractive outcomes after combined procedures is crucial for visual rehabilitation.

Purpose of the Study:

  • To analyze the refractive results of corneal triple procedures.
  • To evaluate the impact of biometry on refractive outcomes in these complex cases.
  • To identify factors influencing visual performance post-surgery.

Main Methods:

  • Retrospective analysis of 52 eyes from 47 patients undergoing corneal triple procedures.
  • Corneal transplantation combined with extracapsular cataract extraction and posterior chamber IOL implantation.

  • Mean follow-up of 39 months, with analysis of pre-operative and post-operative refractive data.

    • Main Results:

    • The majority of patients were elderly females undergoing unilateral surgery.
    • Pre-operative ametropia was common, with contralateral visual acuity often poor.
    • Post-operative refraction commonly stabilized into hypermetropia, leading to suboptimal uncorrected visual acuity.
    • Biometry did not consistently enhance refractive predictability.

    Conclusions:

    • Corneal triple procedures frequently lead to hyperopic outcomes.
    • Current biometry methods may not be sufficient for optimizing refractive results in these cases.
    • Further research is needed to improve refractive predictability and uncorrected visual performance.
