Abstract Details

Purpose:

To evaluate clinical and corneal tomographical changes induced by the implantation of Keraring intrastromal corneal ring segment (ICRS) in Keratoconus

Setting:

Department of ophthalmology,Tabriz university of medical science,IRAN

Methods:

Keraring segments were placed in 30 eyes of 21 keratoconus patients. The mean follow-up time was6.2 ± 0.6 [SD] months (range 6 to 7.5months). All patients underwent a complete ocular examination and corneal topography which obtained from Pentacam (Oculus Pentacam®, USA). Improvement in uncorrected visual acuity (UCVA), best spectacle corrected visual acuity,refraction and topographic changes including keratometry, maximum anterior and posterior elevation,central corneal thickness and thinnest point thickness and location were analyzed

Results:

No intraoperative or postoperative complications occurred in any of patients.ICRS implantation significantly improved UCVA(P=0.005) and BSCVA(P=0.000) .Mean Spherical equivalent significantly reduced from -6.66±3.52 to -4.42±3.20(p=0.000). A clinically significant reduction in mean keratometry(p=0.000),Max Ant Elevation(P=0.024) and Max Post Elevation(P=0.002) were seen.No clinically significant changes in central corneal thickness,thinnest point thickness and thinnest point location were observed

Conclusions:

With mean follow-up of 6.2 months, Keraring segments implantation caused significant clinical improvement in UCVA , BCVA Refractive Error and Keratometric findings of the most keratoconic patients FINANCIAL INTEREST: NONE
