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, ...

OBJECTIVES To describe the visual outcome of keratoconus managed with Intacs implantation (Addition Technology Inc, Fremont, Calif) and to define criteria that predict good outcome. METHODS This retrospective, nonrandomized, comparative, consecutive case series studied 58 eyes of 43 patients with keratoconus managed by Intacs implantation. The outcome measures were analyzed pre-Intacs and 1 y...

PURPOSE To evaluate the safety and efficacy of modified intracorneal ring segment implantation (INTACS) in the management of moderate and advanced keratoconus (KCN). METHODS A modified procedure of intracorneal ring segment (INTACS) implantation was performed in eyes with moderate to advanced keratoconus that were intolerant to contact lens or spectacle correction. The main outcome measures w...

PURPOSE To report deep corneal vascularization noted 3 years after intrastromal corneal ringsegments (Intacs) implantation for the treatment of keratoconus. METHODS A 33-year-old male keratoconus patient intolerant to rigid gas permeable contact lens in the right eye underwent Intacs implantation. At 2 years postoperatively, slit-lamp examination of the right eye revealed superficial corneal ...

OBJECTIVE To compare visual, refractive, and corneal aberrometric outcomes in keratoconic eyes implanted with intracorneal ring segments (ICRS) implantation using either a mechanical or a femtosecond laser-assisted procedure. DESIGN Retrospective, consecutive case series. PARTICIPANTS A total of 146 consecutive eyes of 106 patients with the diagnosis of keratoconus (68 unilateral and 39 bil...

purpose : to assess the results of intracorneal ring (icr) segments for treatment of patients with pellucid marginal degeneration (pmd) methods : in this prospective interventional case series study, eight eyes of 5 patients with pmd who were contact lens intolerant received one or two intacs (intacs, addition technology) segments. preoperative and postoperative evaluations included slit-lamp e...

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...

OBJECTIVE To evaluate the use of INTACS micro-thin prescription inserts (Kera Vision, Inc., Fremont, CA) for the treatment of keratoconus. DESIGN Prospective, nonrandomized (self-controlled) comparative trial. PARTICIPANTS/INTERVENTION Ten patients from our prospective clinical study who had completed 12 months of follow-up were evaluated. All patients had keratoconus with clear central cor...

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...
