After the natural lens has been removed the lens often replaced by an artificial lens, called an intraocular lens, or “IOL.” A permanent intraocular lens (IOL), which is individually selected for each eye care patient, replaces the cataract lens. This IOL is a plastic lens that requires no care and becomes a permanent part of the eye. The IOL also has an ultraviolet filter to protect the retina, in the back of the eye, from sunlight injury. Cataract surgery is generally a relatively simple outpatient procedure with little discomfort, requiring only a few hours and a topical anesthetic.
The researchers’ analysis of registry data for 837,795 live-born infants in Denmark between 1996 and 2008 found no link between the use during pregnancy of the anti-herpetic agents acyclovir, famciclovir or valacyclovir and the occurrence of major birth defects, after adjusting for several variables. Of 1,804 pregnancies exposed to one of these antivirals at any time during the first trimester, 40 infants ( percent) had a diagnosis of major birth defect, as compared with 19,920 of 835,991 ( percent) unexposed pregnancies.
