Abstract:
Six human epikeratophakia lenticules were remo- ved 1 to 23 months after refractive keratoplasty for aphakia(2)and myopia(3).The myopic group in- cluded one epi-lens treated with ArF-excimer laser for hyperopia.Causes of removal were epithelial de- fect(4),edema of host cornea(1)and overcorre- ction(1),The epi-lens stroma showed a central regular fibrillar structure with a low keratocyte den- sity.Electronmicroscopy revealed preserved cytoplas- mic organelles and nuclear appearance.Lymphocytes and other mono-nuclear cells were absent,Bowan's membrane was normal in all cases.Breaks were not seen while a slight wavy appearance and occasionally focal bends occurred.The epithelium was somewhat irregular and changing in thickness.In the peripher- al wound region stromal and epithelial irregularities were evident.
