Predictability of Tunnel Depth for Intrastromal Corneal Ring Segments Implantation Between Manual and Femtosecond Laser Techniques.
PURPOSE To compare the predictability of intrastromal tunnel depth creation for intrastromal corneal ring segments (ICRS) implantation between manual dissection and femtosecond laser using a high-resolution anterior segment optical coherence tomography (AS-OCT). METHODS This multicenter study included patients with keratoconus who had Ferrara-type ICRS implantation at Hospital de Braga using ...
متن کاملferrara intrastromal corneal ring segments in keratoconus
purpose: to evaluate the efficacy and safety of ferrara intra-stromal corneal ring (fiscr) segments for keratoconus. methods: the study was performed on 57 eyes of 44 patients with keratoconus and clear cornea who were contact lens intolerant. subjects underwent complete ophthalmic examination before surgery. objective and subjective refraction achieving the best visual acuity was used to deter...
متن کاملCorneal asphericity in eye bank eyes implanted with the intrastromal corneal ring.
OBJECTIVE To evaluate the effects of the intrastromal corneal ring, a device developed to reduce myopia, on corneal asphericity in a large set of eye bank eyes. METHODS Forty-one deturgesced eye bank eyes were implanted with intrastromal corneal rings of five different thicknesses, ranging from 0.25 mm to 0.45 mm. Corneal asphericity, before and after implantation, was examined using two diff...
متن کاملSingle intrastromal corneal ring segment implantation using the femtosecond laser after radial keratotomy in a keratoconic patient.
A 33-year-old woman with irregular astigmatism 6 years after radial keratotomy (RK) for keratoconus was treated with implantation of a single intrastromal corneal ring segment (Keraring) using the femtosecond laser. The segment (0.150 mm thick with a 160-degree arc) was inserted in the steepest area (inferior) with no intraoperative or postoperative complications. Six months postoperatively, th...
متن کاملClinical outcomes of MyoRing implantation in keratoconic eyes by using the Femtosecond laser technology
Purpose: To assess the outcomes of the insertion of the MyoRing (DIOPTEX, GMBH, Linz, Austria) by applying the Femtosecond Laser Technology (FLT) method in eyes that have keratoconus problem. Methods: A prospective, nonrandomized, clinical examination was managed. 27 eyes of 15 subjects with stable keratoconus (6 females and 9 males), with lifetimes differing from 14 to 49 years were involved. ...
