Myoring Femtosecond-Assisted Intracorneal in Management of Keratoconus
Journal Title: The Egyptian Journal of Hospital Medicine - Year 2018, Vol 73, Issue 1
Abstract
<strong>Purpose</strong>: To evaluate long term follow‑up data on implantation of a full‑ring intra‑corneal implant (Myoring) for management of keratoconus with no cross linking postoperatively done. <strong>Patients and methods:</strong> A prospective non –randomized interventional clinical study was carried out at Nour- EL–Hayaha Eye Center (Cairo) between July, 2015 and July, 2017.40 eyes of 20 patients with symptomatic marked diminution of vision and keratoconus grade 2 to 4 were enrolled in this study. For all patients, a MyoRing (Dioptex, GmbH, Austria) was implanted using a femtosecond laser (Victus Femto Second Laser SW version 3.2 Technolas Perfect Vision GmbH .Munich, Germany). Inclusion criteria; age was between 18 and 35 years, maximum K reading less than 60D (based on pentacam examination), and a central corneal thickness (CCT) was at least 380 μm. Patients who had corneal scarring, any concomitant ocular disease or any history of ocular surgery were excluded from the study. Patients who failed to complete follow-up examinations one month after the surgery were also excluded. <strong>Results</strong>: 40 eyes of 20 patients 5 males (25%) and 15 females (75%) with keratoconus grade 2 to 4 enrolled in this study with a mean age of 24.6 ± 7.92 years. Preoperatively, mean central corneal thickness (CCT) was 440.25±44.49 μm in the right eye and mean CCT 441.35±43.02 in the left eye, while mean keratometry (K) readings, 52.57±5.24diopters (D) in the right eyes and 50.16±3.59 D in the left eyes. Postoperatively, there was a statistically significant improvement in the uncorrected distance visual acuity(UDVA), corrected distance visual acuity(CDVA), K readings, manifest spherical and cylindrical refractive errors, and spherical equivalent (P<0.05). Mean K reading decreased by 6.8 D, from52.57±5.24D to 45.77±2.16D. No serious intraoperative complications were occurred. <strong>Conclusion</strong>: Myoring had the capability in halting the progression of the disease, Insert it whatever the site of lesion and it was noticed that no need for cross linking done postoperatively.
