Dr. David F. Chang on the wonderful academic journey of WOC 2022丨WOC 2022

Editor's Note The 2022 World Ophthalmology Congress (WOC 2022) came to a successful conclusion today. The academic themes of this online conference are rich and diverse, covering the history, current situation and future of the ophthalmology field, and in-depth discussions on hot topics in various fields of ophthalmology. , and made the participating doctors fully feel the pleasure of "setting a personalized agenda for themselves". At the end of this academic feast, "International Ophthalmology News" specially invited Dr. David F. Chang, a world-renowned ophthalmologist, to conduct an exclusive interview. Dr. Chang shared his wonderful memories of this academic journey in WOC 2022. The WOC 2022, which was originally scheduled to be held in China in conjunction with the "26th National Ophthalmology Academic Conference of the Chinese Medical Association", officially kicked off on September 9. All live speeches have been recorded, and participants who registered for the conference can log on to the website at any time. Check out the exciting academic content at the conference. The 2022 WOC meeting, originally scheduled to be held in China, was instead conducted virtually starting on September 9. All the live presentations were recorded and can be viewed at any time by the registered attendees. After months of planning, our Cataract Project Committee Seven symposia have been developed covering many important issues related to modern cataract surgery. Each symposium includes unscripted group discussions to complement the teaching lectures. Friday's subspecialty day kicks off with 3 cataract surgery debates - multifocal IOL vs monofocal monovision; for or against immediate sequential bilateral cataract surgery; femtosecond laser-assisted cataract surgery (FLACS) vs conventional phacoemulsification Comparison. Co-chaired by Mahipal Sachdev (India) and Gede Pardianto (Indonesia), the session highlighted not only the different perspectives, but also the diversity of opinions around the globe. After many months of planning, our cataract program committee developed 7 symposia covering the wide range of important issues relating to modern cataract surgery. Each symposia included unscripted panel discussion to supplement the didactic lectures. Friday's sub-specialty day started with 3 cataract surgery debates – multifocal IOLs vs monofocal monovision; the case for or against immediately sequential bilateral cataract surgery; and femtosecond laser assisted cataract surgery (FLACS) vs conventional phaco. This session, co-chaired by Mahipal Sachdev (India) and Gede Pardianto (Indonesia), not only highlighted differing viewpoints, but also the diversity of opinions across the globe. Michael Knorz (Germany) and I co-chaired the next session titled "Refractive Cataract/Intraocular Lens Surgery - My Top 5 Topics". In this workshop, Council members spent only 7 minutes listing patient selection related to biometrics/formulas, Toric IOL fixation, multifocal IOL, post LASIK patients and implanted refractive IOL dissatisfaction 5 best topics related to patient management of . After each lecture, council members will have a 5-6 minute group discussion. Along with Michael Knorz (Germany), I co-chaired the next session, called Refractive Cataract/IOL Surgery – My Top 5 Pearls. For this symposium, the faculty were given only 7 minutes to list their 5 best pearls relating to biometry/formulae , toric IOL alignment, multifocal IOL patient selection, post-LASIK patients, and managing unhappy refractive IOL patients. Each rapid-fire lecture was followed 5-6 minutes of panel discussion by the faculty. The final session on Friday was titled " You Make the Call", focusing on cataract complications. Rudy Nuijts (Netherlands) and I presented a total of 4 cases. At various stages, we paused the video and asked the panel members (who had never seen the case) what they would do, and the panelists often disagreed on what treatment strategy to pursue. Finally, we move on to the video so that viewers and panelists can see how Dr. Nuijts or I solve this complex problem. This case-based teaching approach allows viewers to see how experienced surgeons think through complication management thinking when faced with stress. The final Friday session, called You Make the Call, focused on cataract complications. Rudy Nuijts (Netherlands) and I presented 4 cases in all. At different points, we stopped the video to ask the panelists (who had never seen the case) what they would do. They often disagreed on what strategies to employ. Finally, we resumed the video so that the audience and panelists could see what Dr Nuijts or I did to address the complication. This case-based method of teaching allows the audience to observe how leading surgeons think through complication management while under pressure. On Saturday, at a symposium on "Refractive intraocular lens content update" co-chaired by Gerd Auffarth (Germany) and Jose Guell (Spain), the International Council of Ophthalmology gave a review of the continuous The range of vision (EDOF), trifocals, small aperture, optically tunable, and accommodating intraocular lenses were updated, followed by a panel discussion. A workshop co-hosted by Boris Malyugin (Russia) and Sergio Canabrava (Brazil) on Sunday discussed the challenges of fixation of posterior chamber intraocular lenses (PC-IOLs) with insufficient capsular support, proposing a variety of solutions, including iris claw intraocular lenses Lens, anterior chamber intraocular lens (AC IOL), iris suture fixation, rescue of subluxated intraocular lens, Yamane intraocular lens fixation and posterior chamber seamless intraocular lens intrascleral fixation. Saturday featured a symposium on refractive IOL updates, co-chaired by Gerd Auffarth (Germany) and Jose Guell (Spain). Updates on EDOF, trifocal, small aperture, light adjustable, and accommodating IOLs were given by the international faculty. A panel discussion followed. The challenge of PC-IOL fixation with deficient capsular support was addressed in a Sunday symposium co-chaired by Boris Malyugin (Russia) and Sergio Canabrava (Brazil). A wide range of solutions was presented, including iris claw, AC IOL, iris suture fixation, salvaging subluxated IOLs, Yamane flanged IOL fixation, and glued IOL intrascleral haptic fixtion. Nancy Al-Raqqad (Jordan) and Zaina Al-Mohtaseb (USA) co-chaired a workshop dedicated to complex cataract cases, covering topics including Small pupils, white lenses, pseudoexfoliation/ligamentopathy, posterior polar cataracts, and microphthalmia with shallow anterior chambers were followed by a panel discussion after each presentation. The final cataract symposium focused on the challenges of hard nuclear cataract, co-chaired by Yao Ke (China) and Dennis Lam (Hong Kong, China), and covered topics such as nuclear chopping, FLACS for hard nuclear cataracts, complications of hyperhard nuclear, Recommendations to avoid posterior capsular rupture and manual extracapsular cataract extraction (ECCE). A symposium dedicated to complex cataract cases was co-chaired by Nancy Al Raqqad (Jordan) and Zaina Al Mohtaseb (USA). The topics ranged from small pupils, white lenses, and pseudoexfoliation/zonulopathy, to posterior polar cataracts and small eyes with shallow eyes anterior chambers. Panel discussion followed each presentation. The final cataract symposium tackled the challenge of the rock hard cataract. Co-chaired by Ke Yao (China) and Dennis Lam (Hong Kong, China), this session included presentations on chopping techniques, FLACS for hard lenses, co-morbidities with brunescent nuclei, pearls for avoiding posterior capsular rupture in these eyes, and manual ECCE. While WOC 2022 will not be able to hold in-person meetings, there are advantages to virtual meetings. Attendees can selectively watch sessions of interest at home based on their own situation, without being overwhelmed by too much information at once. Attendees can pause recordings to study content on slides and tables, and can replay key sections of lectures and videos. Finally, WOC 2022 has created a unique learning opportunity where attendees can learn from nearly 50 top cataract surgeons from around the world without having to board a plane, which is a wonderful experience. Although we all miss attending live meetings, the virtual format does have advantages. Attendees can selectively watch sessions of interest from home at their own convenience, and without being overwhelmed with too much information all at once. Attendees can pause the recordings to study slides and tables and can replay key parts of lectures and videos. Finally, this is a unique opportunity to learn from nearly 50 leading cataract surgeons from around the world without having to board an airplane. Expert Profile Dr. David F. ChangDr. David F.
