Summary
This summary is machine-generated.

Epikeratophakia offers a safe alternative for keratoconus patients intolerant to contact lenses. This procedure significantly improves visual acuity, with 50% achieving 6/6 vision post-surgery.

Area of Science:

  • Ophthalmology
  • Corneal Surgery

Background:

  • Keratoconus causes progressive corneal ectasia and irregular astigmatism.
  • Contact lens intolerance and poor spectacle acuity are common in advanced keratoconus.

Purpose of the Study:

  • To evaluate the efficacy and safety of epikeratophakia in patients with keratoconus.
  • To assess visual outcomes and refractive changes following epikeratophakia.

Main Methods:

  • Retrospective analysis of the first 15 consecutive epikeratophakia cases for keratoconus.
  • Patients were selected due to contact lens intolerance and inadequate spectacle correction.

Main Results:

  • 73% of eyes had pre-operative visual acuity of 6/60 or worse.
  • Post-operative spectacle acuity improved to 6/12 or better in all but one eye (amblyopia).

  • 50% of eyes achieved 6/6 visual acuity; average post-operative astigmatism was 1.9 diopters.

    • Conclusions:

    • Epikeratophakia is a viable and safe surgical option for selected keratoconus patients.
    • It provides significant visual rehabilitation for those unable to tolerate conventional corrections.
    • It may serve as an alternative to penetrating keratoplasty in specific cases.
