President Trump is scheduled to be in Philadelphia on Tuesday, September 15, 2020 at The National Constitution Center (NCC) in the Independence Mall area. Increased police presence is anticipated in Center City throughout Tuesday afternoon and evening. Please allow extra time if you are going to Wills Eye. Please be advised of area street closures to vehicles beginning at 1:00PM on Tuesday 9/15. Pedestrian access will also be limited in the area. This is subject to change and area restrictions, which could widen, will be lifted once the President departs the NCC. There are also demonstrations planned for Tuesday 9/15 around Independence Mall as well as City Avenue.

Anterior Segment

The anterior segment refers to the front-most region of the eye, and includes the cornea, iris, and lens. Typically, the phrase “anterior segment surgery” refers to surgery performed on the iris and lens (either natural lens, or synthetic intraocular lens placed during cataract surgery).

Many forms of pathology including inherited conditions or trauma can affect the iris or lens and require medical or surgical correction. In addition, some patients may have had a complication from a previous cataract surgery, requiring additional anterior segment surgery to improve visual outcomes. Even after uncomplicated surgery, some patients may experience blurry vision, visual distortions, or aberrations secondary to the intraocular lens placed in the eye, requiring a lens exchange to improve vision. 

The surgeons on our Cornea Service perform a wide range of anterior segment surgery, including cataract surgery (both standard and complex), intraocular lens exchange after previous cataract surgery, management of dislocated intraocular lenses, secondary intraocular lens placement, and iris repair or iris replacement.
