Intracorneal ring segments aided by femtosecond laser for the correction of residual astigmatism after keratoplasty
نویسندگان
چکیده
METHODS: This prospective non-comparative interventional case series comprised eight eyes of eight patients with high residual astigmatism after keratoplasty, who had Keraring® ICRS implantation aided by femtosecond laser (FL). We evaluated uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), refractive astigmatism and corneal maximum (Kmax) and minimum curvature (Kmin) at one, three and six months post-surgery.

Post-keratoplasty astigmatism management by relaxing incisions: a systematic review
Postoperative visual acuity can be limited by post-keratoplasty astigmatism, even with a clear corneal graft. Astigmatism management can be performed by selective suture removal, adjustment of sutures, optical correction, photorefractive procedures, wedge resection, intra-ocular lens implantation, intracorneal ring segments, relaxing incisions with or without compression sutures and repeated ke...
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...
