Purpose:
One aspect of biocompatibility of IOLs can be tested using specular microscopy of the anterior and posterior surface of the lens in vivo.
Methods:
We examined 45 patients after implantation of a "Memory lens" and 31 patients after the implantation of an "Acrysof" lens 3-6 months after surgery.
Results:
Typical deposits (Lens epithelial cells, spindle-shaped macrophages, giant cells, pigment, Wolter membrane) were rarely seen on both types of lenses. There were fewer lens epithelial cells on the posterior capsule and less secondary cataract after implantation of the "Acrysof" lens.
Conclusions:
We did not find any indication of reduced biocompatibility in any of the lenses examined. The reduced rate of secondary cataract after implantation of the "memory lens" may be explained by the fact that this lens type sticks to the posterior capsule better.
