Abstract:To solve some microsurgical procedures in the anterior and posterior chambers using the photo disruptive effect, a special Nd:YAG nanosecond laser device is presented. The Nd:YAG laser is q-switched (Cr 4+ :YAG). The laser beam is expanded. After expansion, the laser beam is passed through a circular variable filter which is rotated by a processor, allowing energy to be set at any value in the range of 0.5-10 mJ. Two infrared LED-phototransistor pairs are used to position the filter. The laser beam is focused … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
