Ophthalmology has been a cu�ing-edge specialty, relying on high-tech instruments and pushing the forefront of microsurgery. While the surgical binocular microscope has been a long-standing piece of equipment for eye surgery, it was not until 2019 that the first 3D digital microscope – a built-in digital viewing system integrated into an ophthalmic surgical microscope – was introduced. The Department of Ophthalmology at HKU was amongst the first tier to acquire the 3D digital surgical microscope during the worldwide launch. Since the delivery in 2020, we have been applying the digital microscope for cataract, retinal, and glaucoma surgeries and research for more than 2 years. The microscope has also enhanced resident training as well as medical student teaching. The new microscope features a 3-dimensional display of the surgical field using two 4k cameras for true digital stereo vision on a 65-inch LED screen. Adopting a natural upright si�ing posture, the surgeon no longer needs to bend the neck and peek into two small eye pieces to view the surgical space. In addition, new filters, lighting features and viewing manipulations are available to see fine structures such as blood vessels, retinal layers, membranes or vitreous humor in high magnification. The viewing system also allows for much larger, detailed images with deeper field of view which can assist delicate retinal surgical procedures. With the development of the digital microscope, microsurgery has finally entered a paradigm shi�. Hong Kong will see the addition of the new digital microscope into public hospitals beginning in 2022. 眼科專科之發展一直依靠高科技儀器推動。手術 顯微鏡一直是所有眼科和眼內科手術的必備工 具。然而，直到2019年市場才推出第一台內置 數碼觀察系統的眼科手術顯微鏡。香港大學眼科 學系是全球首批獲得內置數碼手術顯微鏡技術的 眼科團隊。在這兩年以來，我們已將數碼顯微鏡 應用於白內障、視網膜和青光眼手術和研究。 該顯微鏡加強了住院醫生和醫學生培訓。 新型數碼顯微鏡具備手術視野三維顯示，並使用 兩個4K鏡頭在65英寸LED屏幕呈現真正的數碼 立體影像。外科醫生可採用自然的直立坐姿，不 再需要彎曲頸部來查看手術情況。此外，透過新 的濾光鏡、照明功能和觀察操作，可以更高倍率 查看血管、 視網膜層或玻璃體液等精細結構。系 統還容許觀察更大、更詳細的圖像，並具有更高 的視覺深度，以協助更精細的眼科外科手術程序。 隨著數碼顯微鏡的發展，香港公立醫院將於2022 年增設和應用全新的數碼顯微鏡，眼科手術治療 將進入另一個嶄新模式。 25 HKU Eye Center Inaugural Report The University of Hong Kong
