Three-dimensional digital heads-up microscope for ophthalmic microsurgery



Imaging, Three-Dimensional, Microscopy, Microsurgery, Ophthalmologists


The use of the three-dimensional (3D) digital heads-up microscope is increasingly popular in ophthalmology. Its advantages include improved depth of field, excellent visualization, lower illumination requirements, better ergonomics, and more effective teaching. A pilot study involving 18 ophthalmologists was conducted to compare the 3D microscope with the traditional optical microscope in performing microsurgical steps. Although the mean total operating time to complete five tasks was longer using the 3D microscope than the optical microscope (545 vs 410 seconds, p=0.0009), a downward trend was observed for the mean duration for each task using the 3D microscope. The rapid learning curve reflects the ease of learning and fast adaptation to the new instrument. Operating times may improve with more practice.
