Abstract
The effects of a picosecond (ps) Nd:YLF laser-induced optical breakdown on the irises of five rabbits were investigated by means of iridography and histology and compared with iridotomies obtained using a traditional nanosecond (ns) multimode Nd:YAG laser. The authors' results showed that in the rabbit the Nd:YLF laser creates sharp-edged iridotomies, with little or no disruption of the adjacent iris tissue and vessels. This finding contrasts with that of little and is affected by late perilesional diffusion of the fluorescein at iridography. Nd:YAG laser-induced iridotomies are most often characterized by lacerated margins, with gross cavitations and hemorrhages extending deeply into the perilesional tissues. Acute iritis was also more apparent in the last treatment group.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
