Bilateral spontaneous rupture of anterior lens capsules in a middle-aged woman [PDF]
, 2012 Hypermature cataracts are commonly seen in developing countries. Spontaneous rupture of the anterior capsule, resulting in dislocation of the lens nucleus into the anterior chamber, presents rarely in hypermature cataracts.

Advanced Materials Technologies, EarlyView.Here, it is shown that focused ion beam induced deposition (FIBID) using helium and neon ions enables advanced high‐resolution 3D nanoprinting achieving precise multimaterial architectures and engineered internal voids. Thus, FIBID with finely focused noble gas ion species is presented as a unique platform for designing functional nanomaterials for ...

Advanced Science, EarlyView.Tracking physical impacts is important in many fields. Self‐assembled microparticles made from polydiacetylene and silk fibroin that change color from blue to red when hit can provide an alternative approach to traditional mechanical transducers, quantitatively visualizing impact with responses ranging from <100 to 770 N.

Study of the internal stresses in the capsular bag after the implantation of an intraocular lens and the causes of its dislocation [PDF]
, 2017 Cataract surgery is very common and the majority of these surgeries are successful and are really fast. However, some people who are operated of cataracts have problems after a while (after 5-7 years or more): they suffer a dislocation of the IOL ...
