Abstract Details


To evaluate the effect of a novel radial corneal inlay implant (Corneal Arches) in keratoconus.


Dar Al Oyoun Eye Hospital. Damascus, Syria


This prospective study included 15 keratoconic eyes. Inclusion criteria were stable refraction for 1year pre-implantation and 400microns minimum corneal thickness. Pre-implantation UCVA and BCVA were measured for distance and near. Subjective refraction was taken along with Pentacam scans and contrast sensitivity. Manual radial intracorneal tunnel creation was used by 1 surgeon in all eyes. Determination of the implant location was based on the corneal topography, and identification of the number of implants needed was based on the degree of desired correction. Same measurements were taken post-operatively at months 1,3,6 and 12. Follow-up examination also included both corneal IVCM and OCT.


Patients' age ranged from 16 years to 41 years. Seven right and 8 left eyes were operated. The number of implants used ranged from 1 to 2 arches. Visual acuity improved in 11 eyes while 2 remained the same and 2 eyes had reduced vision at 12 months follow up. No complications were reported in any of the procedures performed.


Corneal arches are novel corneal inlays which can provide an improvement in both unaided and corrected visual acuity in patients with Keratoconus.
