Intracorneal ring segments (ICRS) have been used in patients with keratoconus for slowing keratoconic progression and delaying keratoplasty.1,2 However, we experienced anterior optical coherence tomography (OCT) image distortion of the iris in patients with ICRS insertion by chance. Some femtosecond laser cataract surgery systems use OCT images of the cornea, anterior lens capsule, and nucleus ...

We report risk factors associated with intraocular penetration of caterpillar hair seen at our institute from January 2005 to December 2007. Records of all patients with caterpillar hair induced ophthalmitis (CHIO) were retrospectively reviewed for clinical characteristics, anatomic location of lodgment of the caterpillar hair, treatment methods, and outcomes. Out of a total of 544 cases of CHI...

PURPOSE To report complications after the implantation of intrastromal corneal ring segments (Keraring; Mediphacos, Belo Horizonte, Brazil) in keratoconic eyes using a femtosecond laser (IntraLase; Advanced Medical Optics, Santa Ana, California, USA) for channel creation. METHODS Retrospective chart review of 531 patients (850 eyes) who underwent Keraring insertion using a femtosecond laser f...

Keratoconus is a corneal degeneration that usually appears during puberty and may seriously deteriorate the quality of life of the patients. This corneal disease is today the first indication of corneal transplantation in young patients. Until the last decade of the XX century, keratoplasty procedures were the only alternative to treat this pathological condition. In the beginning of the XXI ce...

PURPOSE We detected keratoconus cases with a significant potential for poor outcomes following intracorneal ring segment implantation (ICRS). We attempted to predict the potential of a case in terms of gain or loss of corrected distance visual acuity (CDVA). METHODS In this retrospective and prospective, consecutive, nonrandomized, multicentric study, 58 keratoconic eyes (aged 1756) were impl...
