Internal pars plana sclerotomy with the contact ND: YAG laser: an experimental study

ABSTRACT

Transvitreal pars plana sclerotomy using the contact Nd YAG laser with a sapphire probe was performed on a group of rabbit eyes and compared with a similar procedure performed with a Ziegler knife. Although the intraocular pressure [IOP] was lowered in both groups of animals, the reduction was greater and more lasting in the group on which the Nd YAG laser with sapphire probe was used. This technique may have application in cases with extensive peripheral anterior synechiae or where a vitrectomy as a combination procedure to clear ocular media is performed
