Hazards of bilateral intraocular lens implantation

Seven patients had bilateral intraocular lens implantation performed with a short interval between procedures, using intraocular lenses of unproven design or deficient quality control All seven patients suffered severe visual impairment, some to the level of legal blindness in both eyes. Lenses with unproven design characteristics should never be implanted in both eyes of a patients. The interval between the first and second procedure, even when using lenses of proven design and quality, should be long enough to insure the long-term successful outcome of the first procedure.
