PRK 8000

Excellent

Refractometry & Keratometry Measurement PRK-8000 provides an extensive dioptric measurement range (-300 to +250) compared to our previous model, and the radius of curvature for keratometry is 5.0mm to 13.0mm. Easy alignment and friendly operation allows you to measure the refraction and keratometry in sequence, and the results can be validated immediately. Owing to its easy alignment and friendly operation which you can measure the refraction and keratometry in a sequence, the results can be checked all at once. .

Key Features & Performance

Ultra-Fast Measurement Speed

Handles both refraction and keratometry in rapid succession—market-leading speed ensures efficient patient flow and maximum throughput.

Semi-Automatic Pupil Tracking

Automatically adjusts head height to maintain optimal alignment, reducing measurement time. Manual mode is also available for control flexibility.

Enhanced Retro-Illumination Mode

Uses light through the pupil to highlight cataract opacity or contact lens faults during measurement. Ideal for early detection.

Peripheral Keratometry

Allows curvature mapping by directing patient gaze to side fixation lamps—helpful in detecting irregular astigmatism and optimizing contact lens fitting.

Diameter & IOL Simulation

Freezes cornea/pupil/lens measurements instantly and enables progressive lens simulation for intuitive patient education.

Tilting & Swiveling Display

7-inch 800×480 VGA TFT screen supports 180° vertical and 135–145° horizontal swivel for ergonomic operation. Touch-screen controls simplify interaction.
