Slit Lamp SL-9900 ELITE

SL-9900 Elite (H) Slit Lamp: Advanced Features for Optimized Ophthalmic Examination

The SL-9900 Elite (H) slit lamp is designed to meet the needs of eye care professionals by offering state-of-the-art features. It combines powerful LED illumination, versatile microscopy options, and compatibility with advanced digital video systems to deliver precise and reliable examination results.

High-Quality LED Illumination

The SL-9900 Elite slit lamp features LED lighting, offering several advantages over traditional lighting systems. LED light provides consistent illumination with a color temperature maintained at 3100 K, ensuring clear and precise images under all lighting conditions. Moreover, the absence of heat emitted by LED light enhances patient comfort during examinations. With an estimated lifespan of 50,000 hours, this technology eliminates the need for frequent bulb replacements, thus reducing maintenance costs.

High-Precision Microscopy

The SL-9900 Elite offers various microscopy options to accommodate diverse clinical applications. It is equipped with a convergent microscope featuring a Galilean-type zoom system, offering magnifications ranging from 6x to 40x. The eyepieces have a 6° convergence angle and ±8 D diopter adjustments for optimal user comfort. These features enable detailed and accurate examinations, facilitating diagnosis and treatment of ocular conditions.

Filtering and Light Diffusion Options

The SL-9900 Elite slit lamp is equipped with multiple filters, including blue, red-free, green (without red), and ND50% filters. These filters enhance the quality of images obtained, especially during fluorescein tests, thanks to the integrated yellow filter that optimizes visualization of ocular structures. Additionally, the lamp features a light diffuser, ensuring uniform illumination of the examination field.

Digital Video System (Optional)

The SL-9900 Elite can be equipped with the high-resolution CSO Digital Vision HR digital camera. This camera captures and records minute details during slit lamp examinations. When connected to the Phoenix patient management software, high-quality images and videos can be stored for later review and analysis. The camera offers a resolution of 1624x1232 pixels, with 14-bit per pixel A/D conversion and a maximum frame rate of 15 frames per second. The USB 3.0 interface ensures fast data transmission, making the documentation process smooth and efficient.

Phoenix Software and Dry Eye Reports

The Phoenix software, used with the SL-9900 Elite, allows for patient data storage and analysis. This software offers advanced features for dry eye evaluation, based on indices such as Ocular Surface Disease Index (OSDI), limbal and conjunctival hyperemia, Meibomian gland analysis, tear meniscus analysis, Non-Invasive Break-Up Time (NIBUT), and tear film osmolarity. By combining these partial scores, Phoenix provides a comprehensive assessment of the patient's clinical condition, facilitating a thorough diagnosis of dry eye.

Polaris: Advanced Tear Film Analysis (Optional)

The optional Polaris system enables advanced analysis of tear film stability and quality by measuring Non-Invasive Break-Up Time (NIBUT). Integrated with the Phoenix software, Polaris records patient data for later review. This feature is crucial for effectively diagnosing and treating tear film disorders, thereby improving patient care for those suffering from dry eye.

Technical Specifications

The SL-9900 Elite boasts advanced technical specifications. The slit lamp projects a slit with an adjustable width from 0 to 12 mm and a length from 1 to 12 mm, with aperture settings of 12, 9, 5, 3, 1, and 0.2 mm. The slit rotation is continuous with a ±90° range on the TABO system, and a variable slit angle from 0° to 20°. The working distance is 80 mm, providing ample space for various clinical manipulations. The joystick, equipped with a push-button, allows precise control of lamp movements during examinations.

Tonometer Compatibility (Optional)

The SL-9900 Elite is compatible with A900, F900, and Z800 applanation tonometers, enabling accurate measurement of intraocular pressure. This compatibility enhances the versatility of the slit lamp, making it a comprehensive tool for ophthalmic examinations.
