30 EW ASCRS PREVIEW March 2013 April 19-23, 2013 Binkhorst Lecture to examine past, present, future of IOLs by Erin L. Boyle EyeWorld Senior Staff Writer T his year's Binkhorst Lecture honoree, Nick Mamalis, M.D., is looking forward to highlighting a topic of great interest to him in the lecture: the history of the intraocular lens. "This is an exciting area, and even though we have undergone a tremendous evolution, there is still room for improvement, and we still have a long way to go," said Dr. Mamalis, professor of ophthalmology, John A. Moran Eye Center, Department of Ophthalmology & Visual Sciences, University of Utah, Salt Lake City. Dr. Mamalis will present this year's Binkhorst Lecture, "Intraocular Lens Evolution: What a Long, Strange Trip It's Been," at the ASCRS Opening General Session on Saturday, April 20, 10 a.m. to 11:45 a.m. "I will talk about different ways of accomplishing restoration of accommodation, near and intermediate vision in addition to distance vision after cataract surgery," he said. "That is what I am going to cover—what is being looked at right IOL development important to the lecture itself. "One of the main people in Europe who was involved in the various designs of IOLs was Dr. Binkhorst," Dr. Mamalis said. "Cornelius Binkhorst [M.D.] designed variations on different iris-fixated IOLs. I'm going to spend some time talking about the evolution of IOLs and how they went from lenses that were fixated to the iris to different designs of lenses that were in the anterior chamber, and then, eventually, going back to the posterior chamber, where we put IOLs now." Binkhorst Lecture honoree Nick Mamalis, M.D., speaks at the ASCRS Winter Update meeting in February. Source: ASCRS now and what is in the near future that we are going to be looking at to try to and improve patients' vision after cataract surgery." He said being selected to give the lecture was a great honor. "I think it is truly one of the highest honors you can receive from ASCRS to be chosen to give the San Francisco Shopping: Quick guide Old Shanghai 645 Grant Ave. 415-986-1222 www.pekingbazaar.com Fudge House Building K, Level 1 415-986-4240 www.fudge-house.com Westfield San Francisco Centre 865 Market St. 415-495-5656 www.westfield.com/ sanfrancisco Tiffany & Co. 350 Post St. 415-781-7000 www.tiffany.com Binkhorst Lecture so I'm very excited, and at the same time very humbled that I was chosen to give this lecture," Dr. Mamalis said. "When I look at the list of the people who have given the Binkhorst Lecture over the last couple of decades, it really is a 'who's who' of people who have done a tremendous amount of work in the area of cataract and refractive surgery." History of IOLs The Wok Shop 718 Grant Ave. 415-989-3797 www.wokshop.com Thos. Moser Cabinet Maker 3395 Sacramento St. 415-931-8131 www.thosmoser.com Dr. Mamalis will begin the Binkhorst Lecture at the invention of the IOL, with inventor Sir Harold Ridley, M.D., and his observation of Royal Air Force (RAF) pilot injuries during World War II. "My mentor David Apple [M.D.] did a lot of research with Sir Ridley and wrote a book about him," Dr. Mamalis said. "It was Sir Ridley's experience treating RAF fighter pilots, who would get shattered bits of cockpit in their eyes, [that led to the choice of the material for the first IOL]. It just fortuitously worked out that the cockpit was made of Plexiglas (PMMA), which was the original material that he chose for making the first IOL. He found that this material was inert and did not cause inflammation when it was inside the fighter pilots' eyes." Sir Ridley performed the first successful IOL surgery in England in 1949, and following that, IOL innovations spread across Europe in the 1960s and 1970s, Dr. Mamalis said. He will trace those innovations in the lecture, including an aspect of Lecture conclusion Dr. Mamalis said he will discuss different IOL materials, designs, and technologies currently on the market, and issues in accommodation and restoring full vision following cataract surgery. In addition, he will look into the future, highlighting research into new kinds of materials and accommodating lenses. Another topic discussed will be the potential for an injectable IOL, which could closely mimic the way the crystalline lens works in the human eye. "I think the conclusion is going to be that we have come a long way from the earliest attempts at designing an IOL by Sir Ridley, which has been more than 60 years now. Over the past 60 years, IOL designs, materials, and finishes have evolved greatly, and I think the main conclusion is going to be we've come a long way but we still have a way to go," Dr. Mamalis said.
