BACKGROUND: Postoperative endophthalmitis after cataract surgery is a severe eye infection that can lead to irreversible blindness in the affected eye. The characteristics, treatment and prognosis of this disease vary because of its association with different pathogens. Here, we report what is possibly the first case of endophthalmitis after cataract surgery to be associated with the rare pathogen Earliella scabrosa. CASE PRESENTATION: A 56-year-old man from Hainan Island (China) with a history of phacoemulsification and type II diabetes mellitus underwent intraocular lens (IOL) implantation...

Jason Hsu
BACKGROUND/PURPOSE: To describe a novel use of the flexible nitinol loop membrane scraper (FINESSE Flex loop; Alcon, Fort Worth, TX) for rescue and refixation of a dislocated intraocular lens (IOL). METHODS: A 27-gauge nitinol flex loop was used to lasso each haptic of a dislocated 3-piece IOL. By retracting the loop, the haptic could be effectively locked to the instrument and externalized through a scleral tunnel, thereby fixating it to the sclera in a sutureless fashion...

We have developed a simple method for the induction of cataracts in adult zebrafish using hydrogen peroxide. Our method uses a corneal puncture followed by intraocular injection of hydrogen peroxide into the anterior chamber. The procedure can be done rapidly, forming a highly opaque cataract almost immediately, and fish recover quickly. The optical clarity of the lens is gradually regained over time, showing the innate ability of zebrafish to regenerate healthy lens tissue. This technique provides a simple in vivo system with which to assess mutant strains or targeted disruptions to genes expressed in the lens...

Aim: Cataract extraction is one of the most frequent surgeries in Germany. In most cases, the clouded natural lens is replaced by a hydrophobic or hydrophilic acrylic intraocular lens (IOL) implant. The most common long-term complication after cataract surgery is the development of a posterior capsule opacification (PCO). Although no precise real world data are available, published evidence suggests a lower risk for PCO development for hydrophobic acrylic IOLs compared to hydrophilic acrylic IOLs...
