چکیده
PURPOSE To report the effect of wavefront-guided photorefractive keratectomy and corneal collagen cross-linking (CXL) on visual problems after Ferrara ring segment placement. MATERIALS AND METHODS A 32-year-old male patient was treated with a Ferrara ring segment for keratoconus. One year later, the ring was removed due to severe glare complaints. After 6 months, wavefront-guided photorefractive keratectomy and CXL were applied simultaneously to correct high order aberration and refractive error. RESULTS Six months after the wavefront-guided photorefractive keratectomy and CXL, the uncorrected distance visual acuity was 20/25, and there was a 30% decrease in coma aberrations. The glare complaint regressed. CONCLUSION Wavefront-guided surface ablation and CXL may reduce high order aberrations and glare complaints after intrastromal corneal ring implantation.

متن کاملRandom Implantation of Asymmetric Intracorneal Rings
Intracorneal ring employment for treating ectasia is widespread. Although the mechanism of action of intracorneal rings in the regularization of the corneal surface after its implantation is well known in most cases, there are still many doubts. We present a case of implanted intracorneal rings, where, despite the peculiar position of the rings, the patient gains lines of visual acuity and kera...

متن کاملActual Indications for Intracorneal Ring Segment Implantation in Keratoconus
Intracorneal ring segments (ICRS) are small synthetic implements designed to achieve refractive adjustment by flattening the cornea. Three common types of commercially available ICRS are Intacs, Keraring and Ferrara rings. Low myopia was the initial indication for implantation of ICRS, and indications later included ectatic corneal diseases (such as keratoconus and pellucid marginal degeneratio...

BACKGROUND To investigate the effects of combined corneal wavefront-guided transepithelial photorefractive keratectomy (tPRK) and accelerated corneal collagen cross-linking (CXL) after intracorneal ring segment (ICRS) implantation in patients with moderate keratoconus. METHODS Medical records of 23 eyes of 23 patients undergoing combined tPRK and CXL after ICRS implantation were retrospective...
