• DMEK IOL Exchange Description: This is a video of dmek/IOL exchange in a patient of mine that underwent Phaco/DSEK 3 years ago in both eyes. Her left eye had a great result, 20/25, spherical equivalent approx -1, but her right eye, in spite of uncomplicated surgery, ended up +3, best corrected Va approx 20/50. Some DSEK patients have poor vision in spite of uncomplicated surgery, sometimes from interface opacities and sometimes from visual aberrations from the DSEK graft itself. In this surgery, I removed the IOL and replaced it with one of higher power, then removed the DSEK graft and replaced it with a DMEK graft. She ended up 20/25 UCVa. I am happy to answer questions about the surgical technique and IOL exchange calculations. Thanks, James Lehmann, MD. Subspecialty: Cornea / External Disease Level: Advanced Uploaded By: James Lehmann
