Stromal rings, also called corneal are small semicircular elements. They are made of inert material, that has unique biocompatibility with the tissues of the eye. These rings are able to serve indefinitely. At the same time, if necessary, for example, at age-related vision changes, you can change their location, and even the diameter. In addition, the ring can be replaced or removed. Thus, the operation of installing stromal rings is completely reversible.

The operating principle of intrastromal rings

Implantation of intrastromal rings - a reliable method of keratoconus correction. Intrastromal rings provide a flattening of the central and peripheral areas of the cornea, preserving its sphericity. Rings size produces their refractive effect: the best refractive outcome is provided by a thick ring, with a minimum diameter.

Advantages of the corneal rings

• Stabilization of the keratoconus progression.
• Rapid return to the traditional way of life after the implant surgery.
• The ability of correction and removal of the rings.
• Absolute biocompatibility of the rings material and eye tissues.
• The possibility of using contact lenses.
• No age restrictions for the installation.
• No limitations in motor activity.

Indications for implantation of stromal rings

• Keratoconus in the stage of progression.
• Pellucid marginal degeneration.
• High myopic astigmatism with the thin cornea.
• Excimer laser-induced corneal ectasia.
• Irregular astigmatism after radial keratotomy.
• Irregular astigmatism, of post-traumatic nature.

Contraindications

• Persistent corneal clouding of the visual axis area.
• Keratometry above 75D.
• The high degree of astigmatism after corneal transplant.
• Hydrops.
• Corneal Infection.
• Unjustified expectations of patients.

Intrastromal rings installation process

Intrastromal rings and corneal segments implantation into the thickness of the cornea is considered the most modern and the most optimal treatment for keratoconus. Shape of the rings, measured in circumference degrees, and their thickness in microns, interposition, localization relatively to the vertical and horizontal axes - all strictly individually and is determined by shape, size and position of the cone apex.

Installation of stromal rings (segments) is performed on an outpatient basis, the operation takes about 20-30 minutes. For painlessness of the procedure local anesthesia drip is applied which eliminates stress on heart, blood vessels and other organs.

In the process of keraring, and that is what such an operation is named, along the perimeter of the cornea two canals are formed through which the stromal rings are implanted into the layers of the cornea. After surgery, the patient is under the supervision of specialists for some time, but later that same day, returns home. The rehabilitation period of this intervention is minimal. For faster recovery, the attending specialist forms a schedule of visits and checkups.

Predictable result

Intrastromal rings (segments) help straighten out the deformation of the cornea surface in the most gentle way, fix its refraction, make a flat cone. Compensation of astigmatism with visual functions improvement take place as a result of these changes. Further development of keratoconus with implanted stromal rings is impossible.

Early and late postoperative complications possible

• Extrusion of segment.
• Bowman's membrane perforation and / or perforation of the cornea.
• The asymmetry in segments position.
• Corneal neovascularization.
• The accumulation around the rings of lipid deposit.
• Infectious keratitis.
• Displacement of the implant in the tunnel.
• The melting of the cornea.
• Epithelial ingrowth into the incision area.
• Aureole effect (halo).
• Chronic pain.
• Haze - superficial corneal opacity.
• Prolonged local swelling around segments.
