Designed for Modern Refraction Workflow
The TSDR-3000 combines compact hardware, wireless operation, automatic testing support, and modern digital workflow integration for efficient clinical environments.
Single Body Concept
The ultra-compact single-body design improves interaction with patients while reducing examination room space requirements.
Wireless Tablet Control
Control the TSDR-3000 wirelessly from a Samsung Galaxy Tab. The tablet interface provides intuitive operation of the digital phoropter during subjective refraction.
Low-Noise & High-Speed
Lightweight lens discs reduce friction, improve rotation speed, and provide quiet and comfortable examinations.
Near Vision Test
Tilting up to 45 degrees and built-in digital near chart support convenient presbyopia and near vision examinations.
Advanced Cross Cylinder Functions
Supports ±0.25D and ±0.50D Jackson cross-cylinder lenses and dual cross-cylinder functions for fast and precise astigmatism and axis measurements.
Bluetooth Device Connection
Easily connect visual acuity charts, auto ref-keratometers, and lensmeters through wireless Bluetooth pairing.
Precision Refraction Technology
Automated phoropter functions, including automatic occlusion and custom test programs, support clinician-guided subjective refraction. The TSDR-3000 also supports phoria testing and advanced prism functions.
Automatic Occlusion
Automatically activates during function changes or lens rotation to minimize accommodative interference.
Prism up to 20△
Supports precise phoria testing with minimum 0.1△ step control.
Monocular PD
Independent left/right PD adjustment supports precise alignment based on patient posture.
Unit Test Programs
Operators can create up to 99 custom test programs for different examination workflows.
Clinical Workflow Demonstration
Explore the TSDR-3000 digital refractor in real clinical environments, including wireless tablet control, automatic occlusion, near vision testing, and Bluetooth device integration.
Monocular PD Adjustment
Monocular PD can be adjusted independently for the left and right eyes, allowing more precise visual acuity testing and refraction based on the patient's facial structure and examination posture.
This helps support accurate alignment and stable measurement conditions during subjective refraction.
Portable Thermal Printer
The portable thermal printer includes a rechargeable battery and wireless Bluetooth connection for unrestricted examination room placement.
Compact portable design improves workflow flexibility in modern clinics.
Patient Posture Alarm
When the patient moves away from the forehead rest, LED indicators notify the operator to maintain proper examination posture.
This supports more stable measurements and improves refraction accuracy.
Bluetooth Mouse Control
In addition to direct touchscreen operation, the system supports Bluetooth mouse control for users who prefer conventional mechanical operation.
The mouse wheel provides jog dial-like functionality, allowing intuitive and familiar control during refraction.

TSDR-3000 Frequently Asked Questions
Is the TSDR-3000 a digital phoropter or a digital refractor?
Both terms describe the TSDR-3000. It is a lens-based instrument for subjective refraction, operated by an eye care professional using a wireless tablet.
What should I check when choosing an automatic phoropter?
When comparing auto phoropter systems, check how the clinician controls the examination and which functions are automated. The TSDR-3000 uses a wireless tablet, supports automatic occlusion during function changes or lens rotation, and allows up to 99 custom test programs. The clinician guides the subjective refraction examination.
