HIGH-RESOLUTION DIGITAL RETROILLUMINATION IMAGING OF THE POSTERIOR LENS CAPSULE AFTER CATARACT-SURGERY

Purpose: To develop a system for high-resolution imaging of the poster ior lens capsule after intraocular lens surgery for objective assessme nt of posterior capsule opacification (PCO). Setting: Department of Ca taract and Refractive Surgery, St. Thomas' Hospital, London, United Ki ngdom. Methods: A system was developed that uses coaxial illumination and imaging based on Zeiss components with a digital camera directly l inked to a computer for online image verification and image analysis. Results: The system produced high-resolution digital images with even background illumination of sufficient quality to demonstrate progressi ve lens epithelial cell changes that are amenable to computer image an alysis. Conclusion: This system produced excellent images for objectiv e documentation and quantitative measurement of PCO.
