The conservation of large carnivores is a formidable challenge for biodiversity conservation. Using a data set on the past and current status of brown bears (Ursus arctos), Eurasian lynx (Lynx lynx), gray wolves (Canis lupus), and wolverines (Gulo gulo) in European countries, we show that roughly one-third of mainland Europe hosts at least one large carnivore species, with stable or increasing abundance in most cases in 21st-century records. The reasons for this overall conservation success include protective legislation, supportive public opinion, and a variety of practices making coexistence between large carnivores and people possible. The European situation reveals that large carnivores and people can share the same landscape.

BACKGROUND Disenclavation is a common complication of prepupillary iris-claw intraocular lenses (IOL). We present a new minimally invasive revision surgery technique for reenclavation of prepupillary iris-claw IOLs using standard 23 Gauge (G) vitrectomy instruments. HISTORY AND SIGNS Three cases of revision surgery by unilaterally dislocated prepupillary iris-claw IOLs are presented. THERAPY AND OUTCOME Two 20 G sideports 90 degrees apart were constructed. Healon 10® was injected to maintain the anterior chamber. A standard enclavation needle was introduced to rotate the optic into correct position and a 23 G endgrasping forceps was used to grasp and stabilize the IOL for enclavation. The reenclavation was successful in all three cases and the mean visual acuity improved from preoperatively 0.1 (range counting fingers [CF] to 0.25) to 0.6 (range 0.4 to 0.8) with no significant induction of astigmatism. CONCLUSIONS This minimally invasive reenclavation technique for repositioning of the prepupillary iris claw IOL appears to lead to successful and rapid visual rehabilitation.
