INTRODUCTION This report describes the first known case of late-onset intrusion of an intrastromal ring segment into the anterior chamber due to posterior migration of a ring segment. To our knowledge, intrastromal ring segment penetration has only been shown to occur in the intraoperative or immediate postoperative period. We postulate that the perforation in this case is due to progressive th...

PURPOSE To report on the use of the Nd:YAG laser corneal disruption in the treatment of infectious crystalline keratopathy. METHOD Case report. A 52-year-old woman with infectious crystalline keratopathy unresponsive to topical antibiotics was treated with an Nd:YAG laser to the intrastromal crystals. RESULTS After Nd:YAG laser treatment, the infiltrate completely cleared within 4 weeks. ...

PURPOSE To examine the corneal repair response after intrastromal femtosecond (fs) laser keratotomy. METHODS Twelve rabbits underwent monocular intrastromal keratotomy performed with an fs laser at a preoperatively determined corneal depth of 160 to 200 microm. The fs laser-induced corneal repair response was compared with that of nonoperated control eyes and eyes treated with photorefractive...

PURPOSE Nd:YAG laser photodisruption with nanosecond (ns) pulses in the millijoule range is an established tool for intraocular surgery. This study investigates tissue effects in cornea, lens, and retina to assess whether picosecond (ps) pulses with energies in the microjoule range can increase the surgical precision, reduce collateral damage, and allow applications requiring more localized tis...

The purpose of this report is to provide a comprehensive account an exceptional case involving the presentation congenital rubella syndrome (CRS) in newborn. Furthermore, it aims document successful regression CRS through medical treatment alone. We present five-day-old infant who was referred our facility as case. patient presented with bilateral white corneal opacity, which observed shortly a...

PURPOSE To evaluate the clinical outcomes of implantation of Ferrara intrastromal corneal ring segments (ICRS) in patients with astigmatism after penetrating keratoplasty (PKP). SETTING Private clinic, Belo Horizonte, Brazil. DESIGN Retrospective consecutive case series. METHODS Chart records of post-PKP patients who had ICRS implantation from May 2005 to September 2009 were retrospective...
