Intrastromal Rings (KeraRings)
Intrastromal rings are also known as KeraRings, and are ring segments that are implanted into the stroma to flatten and regularise the corneal shape in conditions such as keratoconus.
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.

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.
