KeraRings are inserted into a small intrastromal pocket around the region of steepening.

They work by adding material to the stroma which results in regularisation of both the corneal surface and refractive correction (glasses prescription), whilst preserving the natural corneal shape.

They reduce optical aberrations such as glare and halos whilst improving visual acuity and tolerance to contact lenses. It is a reversible treatment and the ring segments are easily removed.

Treatment Benefits Benefits

What are the benefits of Intrastromal Rings (KeraRings)?

  • Improve corneal shape
  • Reduce refractive error
  • Improve vision

How is it performed?

  • 1.Performed under local anaesthetic in sterile treatment room / operating theatre.
  • 2.Patient is laid flat on a bed or reclining chair.
  • 3.Sterile drape is placed and eyelid support inserted.
  • 4.Intra-stromal pocket created using either a femtosecond laser or a manual technique.
  • 5.Intrastromal ring segments (KeraRings) inserted into corneal stromal pockets.
  • 6.Topical anaesthetic and antibiotic drops applied.
Intrastromal Rings (KeraRings)
LaserVision-FAQ-Main

They are used to regularise corneal shape and reduce refractive errors in keratoconus and other ectatic corneal disorders.

They work by adding material to the stroma which results in regularisation of both the corneal surface and refractive correction (glasses prescription) whilst preserving the natural corneal shape. They reduce optical aberrations such as glare and halos whilst improving visual acuity and tolerance to contact lenses.

Implantation is a simple procedure under local anaesthetic using a femtosecond laser or manual technique.

The corneal shape and refraction changes immediately upon insertion and usually stabilises after 3 months.

They have progressive thickness of the ring segments allowing more customisation compared to other intracorneal ring segments. They may be used in combination with other treatments such as: corneal collagen cross-linking, topography-guided PRK, toric ICL and contact lenses.
