Mocean 4000 OCT/OCTA System
The Mocean 4000 represents Moptim’s flagship ophthalmic imaging platform, combining high-speed spectral domain OCT with AI-enhanced image processing and integrated scanning laser ophthalmoscope (SLO) technology. Designed for thorough assessment of retinal, glaucoma, and corneal conditions, the system delivers widefield imaging capabilities previously available only in premium international devices.
Product Overview
Positioned as Moptim’s most advanced diagnostic system, the Mocean 4000 addresses the clinical need for high-resolution, widefield ophthalmic imaging with automated analysis. The system integrates multiple imaging modalities—cross-sectional OCT, en face imaging, and optional OCTA angiography—into a single platform, reducing the equipment footprint and workflow complexity in busy ophthalmology practices.
The Mocean 4000 targets the premium segment of China’s rapidly growing OCT market, where domestic manufacturers have achieved over 50% market share in public hospital procurement. The system competes directly with international platforms from Zeiss, Heidelberg, and Topcon while offering cost advantages through domestic manufacturing.
Key Features
High-Speed Acquisition: The system performs up to 130,000 A-scans per second, enabling rapid capture of widefield 3D volumes while minimizing motion artifacts. This scan speed supports the 12×12mm PanoScan mode, which provides full coverage of the posterior pole in a single acquisition.
AI-Powered Image Enhancement: Proprietary algorithms process multiple image frames to reduce speckle noise and enhance structural detail. The system captures 100 images in less than one second and merges them to create high-definition composite images with minimized noise.
Real-Time SLO Eye Tracking: The integrated scanning laser ophthalmoscope captures up to 50 fundus images per second, providing real-time visualization of the retina during OCT acquisition. The SLO-based eye tracker compensates for eye movement at 100 tracking cycles per second, maintaining scan registration accuracy.
Extended Depth Imaging: With 3.1mm scan depth capability, the Mocean 4000 visualizes structures from the vitreous through the retina to the choroid. The Deep Choroidal Imaging (DCI) mode enhances visualization of choroidal neovascularization and other sub-retinal pathology.
VASCAN OCTA Module: An optional upgrade adds OCT angiography capabilities for non-invasive visualization of retinal and choroidal vasculature without contrast injection.

Clinical Applications
The Mocean 4000 supports thorough ophthalmic assessment across multiple subspecialties:
Retina: HD line scans, radial patterns, and 3D cube acquisitions enable detailed evaluation of macular pathology including age-related macular degeneration, diabetic retinopathy, and epiretinal membranes. The widefield PanoScan mode captures peripheral retinal abnormalities that may be missed by conventional narrow-field imaging.
Glaucoma: Dedicated analysis modules measure optic nerve head parameters and ganglion cell complex thickness. The system provides progression analysis for longitudinal monitoring of glaucomatous damage.
Cornea: Anterior segment imaging with 16mm angle-to-angle scans supports evaluation of corneal thickness, anterior chamber depth, and angle anatomy. Applications include pre-operative assessment for refractive surgery and monitoring of corneal ectasia.

Frequently Asked Questions
What imaging modes does the Mocean 4000 offer?
The system provides nine standard scan patterns organized by clinical application: retina modes (HD line, six-radial lines, multi-frame, 3D cube up to 12×12mm), glaucoma modes (disc analysis for ONH, macular analysis for GCC), and cornea modes (HD line, six-radial lines, angle-to-angle). The optional VASCAN module adds OCT angiography capabilities.
How does the Mocean 4000 compare to imported OCT systems?
The Mocean 4000 offers specifications competitive with premium international platforms, including 130,000 A-scans/s scan speed and 12×12mm widefield imaging. Key differentiators include integrated SLO eye tracking, AI-enhanced image processing, and typically lower acquisition cost due to domestic manufacturing.
Is OCTA included with the Mocean 4000?
OCT angiography is available as an optional VASCAN module upgrade. The base system includes structural OCT imaging with SLO fundus photography.
