In vitro noncontact intravascular femtosecond laser surgery in models of branch retinal vein occlusion.

Purpose: To investigate intravenous femtosecond laser surgery in models of branch retinal vein occlusion.

Materials And Methods: Non-amplified near infrared femtosecond laser was used to ablate polyamide sutures and human hairs inserted into the vascular lumina of porcine retinal veins in vitro. Specimens were subjected to multiphoton laser scanning microscopy and electron microscopy.
