For keratoconus patients intolerant to contact lenses, penetrating keratoplasty is standard. Intrastromal corneal ring implantation offers a refractive alternative, potentially avoiding corneal transplants in select cases.

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Refractive Surgery

Background:

  • Keratoconus treatment varies with disease severity.
  • Contact lenses may fail due to intolerance or insufficient visual acuity.
  • Penetrating keratoplasty is the traditional surgical option for visual rehabilitation in advanced keratoconus.

Purpose of the Study:

  • To explore alternative treatments for keratoconus when conventional methods fail.
  • To evaluate intrastromal corneal ring implantation as a refractive option.
  • To determine if intrastromal corneal ring implantation can prevent the need for corneal transplantation.

Main Methods:

  • Review of treatment modalities for keratoconus.
  • Analysis of intrastromal corneal ring implantation as a refractive surgical option.

Related Experiment Videos

  • Comparison of outcomes between penetrating keratoplasty and intrastromal corneal ring implantation.

    • Main Results:

    • Keratoconus is a contraindication for incisional refractive surgery (e.g., radial keratotomy, laser in situ keratomileusis) due to corneal instability.
    • Intrastromal corneal ring implantation can improve visual function in patients with a transparent cornea.
    • This procedure may obviate the need for corneal transplantation in select keratoconus patients.

    Conclusions:

    • Intrastromal corneal ring implantation presents a viable refractive alternative for keratoconus management.
    • This surgical option can enhance visual acuity and potentially prevent corneal transplantation.
    • Treatment decisions for keratoconus should consider disease severity and patient-specific factors.
