On 27 November 2021, Johnson & Johnson Surgical Vision convened the Expert Panel in Cataract Surgery (EPICS) TECNIS SynergyTM User Meeting with 12 ophthalmologists from across Asia Paci c, moderated by Dr Fam Han Bor. The experts shared best practices and experiences in patient selection, preoperative evaluation and counselling, as well as postoperative management to optimize patient outcomes with TECNIS SynergyTM. Asian patients’ unique near vision needs A de nition of patients’ vision needs after cataract surgery is important when implanting presbyopia-correcting intraocular lenses (PCIOLs),1 with distances of near vision varying according to the occupation and lifestyle of patients, and may include distances of 25, 30, 33, 35 or 40 cm.1-3 While there is often a need to hunt for the sweet spot with existing trifocal IOLs, near visual acuity (VA) is typically measured at 40 cm.4,5 However, visual performance at 33 cm is becoming increasingly important in meeting the near vision needs of Asian patients.1,6 Various studies have shown that Asians generally view reading materials such as their handheld smartphones and books at a closer distance due to their shorter stature – thus, proportionately shorter arm lengths – compared with Europeans and Africans.6,7 Furthermore, the more elaborate and intricate formation of Asian scripts, particularly Chinese scripts, require 1.5 times more VA than English characters.8 Studies have shown that the functional mobile usage distance is at 33 cm (Figure 1), and smartphones are generally held at an average viewing distance of 33.95 cm among Asians.1,6 “Asians need strong near and good intermediate vision due to challenges in reading Asian scripts such as Chinese, Hangul, Thai, Arabic and Japanese,” Dr Prin Rojanapongpun said. “Another consideration is the reading needs of patients, including tablet / book at distances of 30–35 cm and computer monitor at distances of 45–50 cm.” Speaking from experience in Taiwan, Dr Hsiao Yu-Chuan shared that such near vision needs are prominent among Taiwanese owing to the need for reading traditional Chinese script – which is more complex than simpli ed Chinese script.
