the incidence of microbial keratitis after intacs implantation is extremely low and channel infection has been infrequently reported. we present a 23-year-old woman with keratoconus of both eyes who underwent implantation of two intrastromal corneal ring segments (intacs, keravision, inc., fremont, ca, usa) in the right eye. after 2.5 months, the patient presented with decreased vision, inflamm...

PURPOSE To examine epithelial and stromal layers by three-dimensional very high-frequency (VHF) digital ultrasound scanning before and after implantation of Intacs (intracorneal ring segments [ICRS]). METHODS Three-dimensional scanning was performed in five eyes before and 3 months after Intacs insertion. Digital signal processing techniques provided high-resolution B-scan imaging and I-scan ...

PURPOSE: To report a case of bacterial keratitis in a patient with a history of intrastromal corneal ring segments (INTACS®) implantation to correct keratoconus. METHODS: The patient's history, clinical presentation, pathological analysis and therapeutic management were reviewed. RESULTS: A 36-year-old-man was referred to our department due to decreased vision and intense pain in his left eye, ...

PURPOSE To compare the visual, refractive, and keratometric outcomes of single-segment conventional and severe keratoconus (SK) types of Intacs for correction of inferior keratoconus (KCN). METHODS A total number of 41 consecutive eyes of 23 patients with a diagnosis of inferior KCN underwent Intacs implantation. Eight eyes were excluded due to postoperative complications (4 eyes) and loss to...

Intacs, intrastromal corneal rings are widely used to reduce myopia, astigmatism, keratometry readings and high order aberrations in patients suffering from keratoconus, almost 15 years have passed from the first procedure which was performed in the eye of a patient with unsatisfactory visual acuity and contact lenses intolerance. Many publications including book chapters, retrospective studies...

In the past, the main goal of intrastromal corneal ring segment (ICRS) implantation was to reduce keratometry. Current treatment nomograms based on classifi cation of the ectasia phenotype aim to provide both therapeutic and refractive correction. We present the case of a 39-year-old woman diagnosed in 2011 with keratoconus in both eyes, with low best spectacle-corrected distance visual acuity ...

PURPOSE To prospectively study the effects of the use of Intacs microthin prescription inserts for the management of keratoconus. DESIGN Prospective nonrandomized clinical trial. METHODS Thirty-three eyes of 26 keratoconus patients (17 males and 9 females) ages 21 to 51 years (mean age, 32 +/- 9.7 years) were included in the current study. All patients had clear central corneas and contact ...
