Abstract
Purpose: :
To demonstrate the newly developed real time intraoperative OCT and to show the clinical application in the anterior segment surgeries.
Methods: :
We developed the prototype of intraoperative OCT device that can be easily attached to the surgical microscope. It can get the real time OCT images in 98 frames a second. Applying the concept of augmented reality, the device can display the OCT images through the microscopic ocular. After the evaluation of the shadowing of the various surgical instruments, the intraoperative OCT images during the cataract and corneal transplantation surgeries were obtained.
Results: :
In OCT images, metallic instruments such as forceps and needles showed total shadowing. Silicone tips and acrylic IOL showed mild to moderate shadowing. During cataract or secondary IOL implantation, we could find the anatomical land marks and evaluate the position of IOL. While performing the corneal transplantation, we could evaluate the the position and state of the graft and recipient, especially in DALK and DSEK operations.
Conclusions: :
Using the intraoperative OCT, we could get more informations of the eye in real time. Surgical efficiency and accuracy could be improved.
