New endoscopic technique to analyze various modern specialized intraocular lenses in research eyes and human eyes obtained postmortem.
OBJECTIVE
To describe a new modification of the Miyake-Apple posterior video photographic technique and its 2 variations. We have developed a new endoscopic technique that is especially amenable for observation of modern specialized intraocular lenses (IOLs).


METHODS
Laboratory study.


METHODS
Three cadaver eyes obtained postmortem.


METHODS
Human eyes obtained postmortem were prepared according to our modified preparation technique used for analyses of whole globes. An intraocular endoscope was utilized to demonstrate all aspects of the interior of an experimentally implanted IOL, with specialized reference to anterior segment structures, obtaining posterior, oblique, and side view images.


METHODS
Different interior dynamic views of the anterior segment structures before and after implantation of an IOL.


RESULTS
High-magnification images of different intraocular structures both before and after device insertion as well as the device itself were obtained. Oblique and side view images from different locations were also available and informative. These images helped to create a 3-dimensional view of these objects and their relations to the surrounding structures.


CONCLUSIONS
The combination of the intraocular endoscope with the closed-system technique is a useful addition to our 3 previously described techniques: (1) the original Miyake-Apple posterior video/photograph technique and the (2) closed system and (3) side/oblique view (keyhole technique) modifications.
