Endolenticular phacolysis using the erbium:YAG laser on human autopsy lenses: a histopathologic study

A pulsed erbium:YAG laser equipped with a 1-m zirconium fluoride fiber coupled with a sapphire tip was used to photovaporize human autopsy lens tissue. Measured diameter of photovaporization of human lens cortex with erbium:YAG laser ranged from 117 micrometers at a fluence of 3.98 J/cm2 to 227 micrometers at fluence of 15.92 J/cm2. Measured diameter of photovaporization of human lens nucleus with Erbium:YAG laser ranged from 265 micrometers at a fluence of 11 J/cm2 and 295 micrometers at a fluence of 15 J/cm2. Endolenticular phacovaporization with the Erbium:YAG laser appears to be a potentially efficient and precise means of removing the human lens.
