February 2013 Figure 2A: Phaco tip puncturing an intact anterior capsule and aspirating and debulking the nucleus Figure 2B: Ophthalmic viscosurgical device injected into the anterior chamber, with good visualization of the capsular tear Figure 2C: Completion of a continuous curvilinear capsulorhexis when the phaco tip is introduced, the eye will be pushed to a nasal position. A second instrument can be placed into the paracentesis to pull the eye back to an ortho position before the phaco capsulotomy is performed. A larger wound and phaco tip are also advantageous because there is less chance of the handpiece becoming occluded, thereby decreasing the risk of wound burn and facilitating removal of the dense lens fragments. In conclusion, phaco capsulotomy is a safe and effective technique for preventing the Argentinian Flag Sign. By using the phaco tip to simultaneously create an anterior capsular puncture and remove the liquefied cortex and nucleus, the lens/capsule apparatus is decompressed and the impetus for the capsulorhexis to spontaneously tear outward is eliminated.

McCannel, M.D., died on December 30, 2012, in his home in Indianapolis. He was 96 years old. ������Mac��� was a special man,��� said Richard L. Lindstrom, M.D., adjunct professor emeritus, ophthalmology department, University of Minnesota, Minneapolis, and founder, Minnesota Eye Consultants, Minneapolis. ���He pioneered practice management methods, including the use of ophthalmic technicians to take histories, perform refractions and other testing prior to being placed in one of multiple surgeon consultation rooms at a time when most ophthalmologists were performing all testing themselves. This allowed him to see a large number of patients per hour and develop a high volume surgical practice.��� Dr. Lindstrom said Dr. McCannel was an early adopter of IOL implants. ���The famous McCannel suture was developed, in part, to manage the subluxations associated with early iris clip intraocular lenses implanted after intracapsular cataract extraction,��� he said. ���Amazing to me, he was an avid reader of the ophthalmic literature 20 years after he retired from clinical care and could astutely discuss both advances in technology and technique, as well as the societal impact of the changing care delivery models. A humble and caring man, he was loved by his patients, employees (including my wife Jaci Lindstrom who was a COMT and scrub tech for him), colleagues, family, and innumerable friends. He will be missed, but his impact on how we interact with patients today lives on in hundreds of practices worldwide.��� According to his obituary printed in the Indianapolis Star Tribune, Dr. McCannel was born in Minot, N.D., earned his bachelor���s degree in 1937 at the University of Minnesota, his M.D. in 1941 from Temple University School of Medicine, Philadelphia, and his M.S. in 1946 from the University of Minnesota School of Medicine. He practiced ophthalmology with his father, Archibald D. McCannel, M.D., in Minot for several years before moving to Minneapolis in 1949 and establishing Ophthalmology, P.A., where he remained for 42 years until his retirement in 1991. From 1957 to 1983, Dr. McCannel traveled with Project Hope, Medico-Care International, and Project Orbis to administer free eye surgery to the less fortunate around the globe, the obituary said. He was the author of numerous articles and textbook chapters including a definitive paper describing a surgery technique he developed called the McCannel suture. He is survived by his wife, four daughters, and five grandchildren. Dr. McCannel was cremated and his final request was for no memorial service. EW
