Keratoconus (KC) patients frequently seek the benefits of Intacs Intracorneal Ring Segments (ICRS) as these devices improve the corneal curvature (topography) and also in many patients remarkably slows down the progression of KC, making corneal transplantation less likely.  Alan N. Carlson, M.D., Professor of Ophthalmology and Chief of the Corneal and Refractive Surgery Services at the Duke Eye Center in Durham, North Carolina sees a large number of patients with Keratoconus from Raleigh and Durham and Chapel Hill and has wondered if Keratoconus may be more prevalent in North Carolina in comparison to other regions.  One question that always comes up is what are the long term risks of Intacs (ICRS) and will these rings be problematic later in life when a cataract develops.  Carlson reports “The most common finding I see with Intacs occurs in patients who are aggressive with eye rubbing which can cause the spacing between the ring segments to become asymmetric.”  One patient referred to the Duke Eye Center in Durham, NC, previously for Intacs now returns after developing cataracts (unrelated to keratoconus or Intacs).  The video demonstrates that the Intacs ring segments do not significantly interfere with the visibility during surgery or any of the technical considerations related to cataract surgery.
