New treatments like collagen cross-linking and lamellar keratoplasty offer alternatives to corneal transplantation for ectatic disorders. These advanced procedures improve corneal rigidity and visual rehabilitation, enhancing patient outcomes.

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Vision Science

Background:

  • Corneal ectasia management is evolving with novel surgical and nonsurgical interventions.
  • Keratoconus, postrefractive surgery keratectasia, and peripheral ectatic disorders present unique challenges.

Purpose of the Study:

  • To review and assess recent studies on emerging treatments for corneal ectasia.
  • Focus on keratoconus, postrefractive surgery keratectasia, and peripheral ectatic conditions.

Main Methods:

  • Review of current literature on novel surgical and nonsurgical approaches.
  • Evaluation of treatments aimed at enhancing corneal rigidity and stromal integrity.

Main Results:

  • Nonsurgical options like collagen cross-linking and intrastromal corneal ring segments aim to increase corneal rigidity.

  • Anterior lamellar keratoplasty techniques (DALK, microkeratome/laser-assisted) allow targeted stromal replacement.
  • Peripheral lamellar keratoplasty reinforces peripheral stroma, reducing astigmatism.

    • Conclusions:

    • Advanced lamellar keratoplasty and other novel surgeries are safe alternatives to penetrating keratoplasty.
    • These procedures offer improved visual rehabilitation and tectonic stability for various corneal ectasias.
