AbstractsPurposeWe aimed to systematically review the existing evidence and determine the efficacy of MyoRing as a novel method for treatment of keratoconus using meta-analysis.MethodsOnline electronic search of Medline, ISI Web of Science, Embase, Scopus, and Cochrane Library databases was performed with reference lists of relevant articles for pre–post trials published through August 2017. Uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), sphere, cylinder… Expand

Effects of intracorneal ring segments on the biomechanical response of the ectatic cornea to air-puff: A patient-specific numerical analysis
The assessment of the underlying factors that influence the biomechanics and dynamics of the cornea is essential for preserving the safety and efficacy of refractive surgeries. In the present work,Expand
Corneal Biomechanics After Intrastromal Ring Surgery: Optomechanical In Silico Assessment
TLDR
A biomechanical framework to better understand the postsurgical optomechanical behavior of the cornea after ring implantation is provided and implants do not stiffen the corneal shape but create a local bulkening effect that regularizes the corNEal shape by modifying corneAL kinematics without canceling corneals motion. Expand
Ectatic diseases.
TLDR
Nomenclature of ectatic disease, etiology and pathogenesis, along with treatment options, are discussed, with special focus on KC and forme fruste keratoconus. Expand

MyoRing Implantation in Keratoconic Patients: 3 years Follow-up Data
TLDR
MyoRing implantation using the Pocket Maker microkeratome was found to be a minimally invasive procedure for improving visual acuity and refraction in the majority of the patients with keratoconus. Expand
Full-Ring Intracorneal Implantation in Corneas With Pellucid Marginal Degeneration
TLDR
MyoRing implantation using the PocketMaker microkeratome appears to provide an effective method for treating pellucid marginal degeneration and with regards to corneal topography, a significant reduction was observed in keratometric values. Expand
Continuous corneal intrastromal ring implantation for treatment of keratoconus in an Iranian population.
TLDR
MyoRing implantation has an acceptable efficacy profile in moderate and advanced keratoconus and both spherical myopia and astigmatism underwent reduction, but the reduction in myopia was more remarkable thanAstigmatism. Expand
Intracorneal continuous ring implantation for keratoconus: One‐year follow‐up
TLDR
Treatment of keratoconus with ICCR implantation significantly improved visual function and the UDVA and CDVA also improved during the first postoperative year. Expand
Implantation of a Complete Intrastromal Corneal Ring at 2 Different Stromal Depths in Keratoconus
TLDR
In both groups, uncorrected distance visual acuity significantly improved after MyoRing implantation, whereas neither of these showed any improvement in the corrected distancevisual acuity. Expand
Clinical evaluation of two types of intracorneal ring segments (ICRS) for keratoconus
TLDR
KeraRing (A) and MyoRing (B) corneal implants both performed well in improving vision and stabilising the cornea, but CDVA improved only in the Keraring group, at the final visit. Expand
Predictability, Stability and Safety of MyoRing Implantation in Keratoconic Eyes During One Year Follow-Up
TLDR
MyoRing implantation in keratoconic patients improves SE, UDVA and CDVA significantly and the improvement in UDVA was remarkable, indicating the procedure was safe and effective in treatment of patients with moderate and severe keratoconus. Expand
Comparative Study between Myoring and Ferrara Ring Intracorneal Implantation Using Femtosecond Laser for Treatment of Keratoconus
TLDR
There were no differences in different parameters except that the Ferrara ring showed more improvement in BCVA and spherical component and the anterior segment OCT in assessment of implanted rings helped to explain the non-improvement in visual outcomes despite the refractive and topographic improvements. Expand
Implantation of a complete corneal ring in an intrastromal pocket for keratoconus.
TLDR
The corneal intrastromal implantation system using a complete ring implanted in a stromal pocket can achieve significant improvements in the visual function of patients with keratoconus. Expand
[Clinical Results after Continuous Corneal ring (MyoRing) Implantation in Keratoconus Patients].
TLDR
The MyoRing implantation is an effective and safe method in improvement of visual functions in keratoconus patients and clinical results are stable in one and two years follow-up time. Expand
