Continuous Intracorneal Ring Implantation in Keratoconus: Efficacy, Predictive Factors, and Complications.

Purpose: To examine the clinical outcomes, predictors of visual improvement and complications of continuous intracorneal ring (ICCR) implantation in patients with keratoconus and confirmed contact-lens intolerance (CLI).

Methods: This nonrandomized, multi-centric, retrospective cohort study examined visual, keratometric and clinical outcomes evaluated after a minimum follow-up of 2 months. Among the inclusion criteria for the standard treatment group (STG) were corrected distance visual acuity (CDVA) <20/25 Snellen, no central corneal scars, minimum corneal thickness >350µm, and central mean keratometry reading (meanK) <55 diopters.

MyoRing treatment of myopia.

Introduction: Laser Vision Correction is not always possible for the treatment of myopia. The aim of this paper is to present results after MyoRing implantation in myopic eyes who in their majority were not eligible for LVC. Safety, effectivity and patient selection is discussed.

Long-term results of MyoRing treatment of keratoconus.

Purpose: To study long-term results of MyoRing treatment of keratoconus.

Methods: Retrospective study of MyoRing implantation into a corneal pocket for keratoconus.

Results: Corneal thickness at the thinnest point remained unchanged, SIM K's, manifest sphere and cylinder were significantly improved at the first follow-up 9 months postoperatively and remained stable until the last follow-up about 5 years after surgery.

Biomechanics of Corneal Ring Implants.

Purpose: To evaluate the biomechanics of corneal ring implants by providing a related mathematical theory and biomechanical model for the treatment of myopia and keratoconus.

Methods: The spherical dome model considers the inhomogeneity of the tunica of the eye, dimensions of the cornea, lamellar structure of the corneal stroma, and asphericity of the cornea. It is used in this study for calculating a strengthening factor sf for the characterization of different ring-shaped corneal implant designs.

Clinical outcomes after complete ring implantation in corneal ectasia using the femtosecond technology: a pilot study.

Purpose: To evaluate the clinical outcomes after implantation of the MyoRing (DIOPTEX GmBH, Linz, Austria) by means of femtosecond laser technology in eyes with corneal ectasia.

Design: Retrospective, consecutive, nonrandomized, case series.

Participants: A total of 12 eyes of 11 patients with ages ranging from 17 to 50 years were included.

Intracorneal continuous ring implantation for keratoconus: One-year follow-up.

Purpose: To evaluate intracorneal continuous ring (ICCR) implantation for the treatment of keratoconus.

Setting: Eye specialist centers, Europe and Middle East.

Method: This study assessed the results of implantation of a MyoRing ICCR in 15 eyes with keratoconus.

Corneal crosslinking and visual rehabilitation in keratoconus in one session without epithelial debridement: new technique.

A new surgical technique for the treatment of keratoconus is presented. This technique combines a new corneal crosslinking method with implantation of a flexible full-ring implant into a "closed" corneal pocket via a narrow incision tunnel in 1 surgical session. Riboflavin is not applied in the form of eyedrops onto a corneal surface after epithelial removal but is instilled into the corneal pocket without the need for epithelial debridement.

Adjustable intracorneal ring in a lamellar pocket for keratoconus.

Purpose: No theory or method currently exists to preoperatively predict the optimal position of an intracorneal implant for the treatment of keratoconus, or a surgical system or technique to adjust and optimize the position of the implant after its implantation. A surgical technique for adjusting the position of the implant inside the cornea is presented, and by adjusting the position of the implant after its insertion into a corneal pocket, the surgical results in keratoconus treatment may be improved.

Methods: After the formation of a closed pocket of 9 mm in diameter and 300 mum in depth within the corneal stroma, a flexible full-ring implant is inserted into the corneal pocket via a narrow incision tunnel.

Implantation of a complete corneal ring in an intrastromal pocket for keratoconus.

Purpose: to evaluate the refractive and visual results of a new treatment for keratoconus using the corneal intrastromal implantation system (CISIS).

Methods: six eyes of four patients with keratoconus were treated with CISIS. Follow-up was 1, 3, and 6 months.

Corneal intrastromal implantation surgery for the treatment of moderate and high myopia.

I describe a corneal intrastromal implantation technique that uses a new type of microkeratome to create a closed intrastromal pocket as well as a continuous ring-shaped inlay with shape memory for placement in the pocket. The technique is a minimally invasive way to treat patients with moderate and high myopia. It can be considered an alternative to laser in situ keratomileusis and phakic intraocular lens implantation in these cases.
