MYORING

MyoRing is a 360° continous full-ring implant to be implanted into a corneal pocket for the treatment of Myopia and Keratoconus. The internationally patented device combines two a-priori contradictory qualities: rigidity for the modelling and stabilisation of the corneal shape after implantation and flexibility (shape memory) for the implantation via a small pocket entry to preserve the corneal biomechanics.

In Keratoconus, MyoRing implantation performed by a DIOPTEX trained surgeon is the only treatment method which can achieve both, Visual Rehabilitation AND Stop of progression. For detailed clinical information on MyoRing treatment of keratoconus click -> here.

In Myopia, MyoRing implantation performed by a DIOPTEX trained surgeon can achieve spectacle free living even in cases not eligible for Laser Vision Correction in a minimally invasive and easily reversible way. For detailed clinical information on MyoRing treatment of myopia click -> here.

In order to preserve the biomechanics of the cornea it is most important to keep the width of the corneal pocket entry less than 5.5 mm. To achieve optimal visual results it is important to create the corneal pocket for MyoRing implantation by using the PocketMaker Ultrakeratome which guarantees a perfectly smooth interface and, consequently, adaptation of the corneal shape to a new biomechanical equilibrium.

The MyoRing can be considered as a kind of "permanent contact lens" which is not really a lens but a ring and which is, unlike a normal contact lens not worn on the top of the cornea but 0.3 mm beneath the corneal surface inside the cornea.

The treatment is minimally invasive and easy to perform. It is intra- and  postoperatively painless with a very short rehabilitation time. Neither a corneal tunnel or a radial cut nor a suture is required, the implantation site is self sealing and heals within a few hours!

Insertion, exchange or removal of MyoRing is almost as easy to perform as of a normal contact lens and takes less than one minute. The safety of the procedure is highly proven in thousands of treatments. 

MyoRing Corneal Implant

Indications:

Myopia:
All grades of Myopia between 1 dioptre and 20 dioptres even if not eligible to Excimer Laser treatment such as:

  • thin corneas
  • irregular corneal surface
  • forme fruste keratoconus
  • high myopia
  • the patient denies LASIK but wants a minimally-invasive and easily reversible myopia treatment 

Keratoconus:

All grades of non-central and central Keratoconus, PMD as well as post-LASIK Keratectasia as long as the minimal corneal thickness is larger than 350 microns. According to the long-term results of up to 8 years MyoRing cannot only achieve visual rehabilitation but also stop of progression of the disease. MyoRing is therefore also indicated for the treatment of progressive cases of keratoconus without the need of cross linking.

1 The recommended 350 microns minimal corneal thickness are for the use of the PocketMaker Ultrakeratome for pocket creation at 300 microns depth. When using Femtosecondlaser, the required minimal corneal thickness may be larger than 350 microns. In this case user of Femtosecondlasers are requested to follow the related instructions.
