Cataract surgery
Today’s cataract surgery can be labeled miraculous compared to the days before Intra Ocular Lens (IOL) implants. In the olden days, the cataract lens was removed completely and the refracting power required to see, had to be provided with a spectacle lens. Because the spectacle lens could only be placed in a position some 13mm from where the natural lens was, it caused about thirty percent magnification. To the patient, everything looked much bigger and affected spatial judgment. These glasses were also ugly and very heavy. It was really tough to cope after cataract extractions.
