Sumario:To evaluate images and videos behind the anterior segment of cataract surgery with the porcine eye using a new Miyake-Apple View with a nasal endoscope. SETTING: Sugiura Eye Clinic, Fuji, Shizuoka, Japan. DESIGN: Laboratory study. METHOD: A hole was made in a commercially available wooden desk and the nasal endoscope was fixed under the desk. A tunnel for passing the probe of the nasal endoscope was opened on a Styrofoam human-faced base, and the probe was passed through. A 3 mm × 3 mm incision was made behind the globe, and a nasal endoscope probe was inserted to observe the posterior anterior segment of the eye. RESULT: The posterior part of the anterior segment of the eye could be clearly observed, and each procedure (hydrodissection, phacoemulsification, irrigation and aspiration, and insertion and fixation of intraocular lens [IOL]) in normal cataract surgery could be observed from the posterior. Lighting could be improved. CONCLUSIONS: The conventional Miyake-Apple View required a large-scale custom-made device, which was expensive and could not be taken easily, and required to cut the globe and a technique to fix it to the glass plate. However, this method made it easy to prepare for shooting, and the equipment was inexpensive. Furthermore, it had the great advantage of not having to cut the globe. Since the integrity of the globe was maintained, normal cataract surgery could be reproduced and dynamic observation from the back became possible. It was useful for practicing cataract surgery and examining the fixed state of new IOLs.
