Pseudophakic bullous keratopathy. A clinical-pathologic analysis.

P Berkowitz, R B Orton, D Boyaner

    Canadian Journal of Ophthalmology. Journal Canadien D'Ophtalmologie
    |January 1, 1979
    PubMed
    Summary

    Intraocular lens implantation led to a higher incidence of bullous keratopathy and corneal edema compared to standard cataract surgery. Factors like corneal touch and iritis contributed to these complications in lens implant patients.

    Area of Science:

    • Ophthalmology
    • Corneal Surgery
    • Intraocular Lens Implantation

    Background:

    • Cataract surgery is a common procedure.
    • Intraocular lenses (IOLs) are frequently implanted during cataract surgery.
    • Corneal complications can arise after cataract surgery.

    Purpose of the Study:

    • To compare the incidence of corneal complications between intraocular lens implantation and standard cataract extraction.
    • To identify factors associated with corneal complications in patients receiving intraocular lenses.

    Main Methods:

    • Retrospective analysis of 226 patients who received IOLs and 90 patients who underwent standard cataract extraction by the same surgeon over three years.
    • Clinical examination and pathological assessment of corneas requiring keratoplasty.

    Main Results:

    • Bullous keratopathy occurred in 6.2% of IOL patients versus 2.2% of standard extraction patients.
    • An additional 4.0% of IOL patients experienced peripheral or intermittent corneal edema.
    • Corneal touch, prolonged postoperative iritis, and recurrent lens dislocation were linked to increased complication rates in IOL patients.
    • Pathological findings in explanted corneas included epithelial edema and endothelial cell loss.

    Conclusions:

    • Intraocular lens implantation is associated with a higher risk of corneal complications, including bullous keratopathy and edema, compared to standard cataract extraction.
    • Preventive strategies targeting intraoperative factors and postoperative inflammation are crucial for mitigating these risks.
