Mastering Anterior Segment Diagnostics: The Clinical Impact of the Rexxam RET-700 AR-Kerato Topographer
The Workflow Challenge in Modern Ophthalmic Triaging
Traditional baseline screening forces patients to physically move between multiple diagnostic stations. A patient might start at the auto refractometer machine, move to a separate topographer for a contact lens fitting, and finally proceed to a slit lamp for tear film analysis.
This fragmented approach introduces significant operational friction:
Increased Chair Time: Every machine transfer adds minutes to the diagnostic process, capping the maximum number of daily OPD consultations.
Data Silos: Operating disparate machines often requires manual data transcription into the Electronic Health Record (EHR), increasing the risk of transcription errors during critical IOL (Intraocular Lens) calculations.
Capital & Spatial Drain: Purchasing and housing three separate units consumes valuable real estate in the eye clinic equipment layout and drastically increases long-term maintenance costs.
The Rexxam RET-700 directly solves these bottlenecks. It is a comprehensive corneal analyzer and refractive workstation designed to capture a complete anterior segment profile in seconds without the patient ever leaving the chinrest.
Technical Deep-Dive: Core Capabilities of the Rexxam AR-Kerato Topographer
Engineered by Rexxam (formerly Shin-Nippon)—a brand globally synonymous with Japanese optical perfection—the RET-700 is built for heavy-duty, continuous operation. Here is a breakdown of its primary clinical modalities.
1. High-Precision Auto Refraction & Keratometry
At its core, the RET-700 is a world-class kerato refractometer. It utilizes a wide measurement range to capture accurate spherical, cylindrical, and axial data even in highly myopic or astigmatic patients.
Advanced Auto-Fogging: The device employs a rapid auto-fogging mechanism that relaxes the patient’s ciliary muscle accommodation, preventing falsely myopic readings during routine pediatric or young adult screenings.
Small Pupil Capability: The unit can capture accurate refractive data through pupils as small as 2.0 mm, making it an indispensable piece of eye examination equipment for elderly patients with senile miosis or those suffering from early-stage cataracts.
2. Comprehensive Corneal Topography
Unlike a standard auto keratometer that only measures the central 3 mm of the cornea, the RET-700 features an integrated Placido disc system that maps the entire corneal surface.
High-Resolution Placido Rings: It projects a highly defined series of rings onto the tear film, capturing thousands of data points to generate detailed axial, tangential, and elevation topographic maps.
Presurgical Screening: This data is critical for ruling out subclinical keratoconus before refractive surgeries (LASIK/PRK) and for calculating precise Toric IOL axes prior to premium cataract surgeries.
Contact Lens Fitting: The onboard software includes specialized contact lens fitting simulation, assisting optometrists in selecting the perfect base curve for rigid gas permeable (RGP) or scleral lenses.
3. Retro-Illumination & Ocular Surface Analysis
The capabilities of this ophthalmic machine extend far beyond refractive data. The RET-700 serves as a vital tool for anterior segment pathology screening.
Retro-Illumination Mode: The device captures high-resolution images of the crystalline lens using retro-illumination. This allows the clinician to objectively document the size and density of cortical and posterior subcapsular cataracts, facilitating better patient education and surgical conversion.
Meibomian Gland & Tear Film Observation: With the rising prevalence of Dry Eye Disease (DED), the RET-700 includes specialized light sources to evaluate tear film stability and capture images of the meibomian glands, adding immense value to your dedicated dry eye clinic.
Hardware Ergonomics and Digital Integration
Procuring top-tier medical ophthalmic technology is only effective if your staff can operate it efficiently. Rexxam has designed the RET-700 with user-centric ergonomics.
Fully Automated Alignment & Capture: The device features a 3D auto-tracking system. Once the operator aligns the targeting box roughly over the patient’s eye via the large color touch-screen, the machine automatically executes the X-Y-Z axis micro-alignment and fires the measurement sequence. This drastically reduces the learning curve for new optometry staff.
Integrated Database & Connectivity: The RET-700 boasts an internal database capable of storing thousands of patient files. More importantly, it features seamless DICOM and LAN connectivity, allowing topographer maps and refractive data to be pushed instantly to the surgeon’s consultation room monitor or the hospital’s central EHR.
The Financial ROI: Why Consolidate Your Ophthalmic Equipment?
When upgrading your eye hospital equipment, the total cost of ownership (TCO) must be analyzed. Purchasing the Rexxam RET-700 provides immediate financial leverage:
Lower Capital Expenditure: The combined price of a premium auto refractometer, a standalone topographer, and a dry eye imaging unit far exceeds the cost of a single RET-700 workstation.
Optimized Floor Space: Real estate is a premium in any clinic. Replacing three machines with one frees up space for additional consultation chambers or minor procedure rooms.
Increased Patient Throughput: By automating alignment and capturing refraction, keratometry, and topography in one continuous sequence, clinics can process significantly more patients per hour during peak morning OPD rushes.

Frequently Asked Questions (FAQ)
A standard auto refractometer only measures a patient's refractive error (sphere, cylinder, axis) to determine their glasses prescription. An AR-Kerato topographer, like the Rexxam RET-700, combines that function with an auto keratometer (measuring central corneal curvature) and a Placido disc topographer (mapping the entire 3D elevation of the cornea), providing a complete anterior segment profile in one device.
A corneal analyzer or topographer is absolutely necessary for detecting corneal irregularities such as keratoconus, which contraindicates LASIK surgery. It is also heavily utilized for calculating the exact placement of Toric intraocular lenses during cataract surgery and for fitting specialty contact lenses.
Yes. The Rexxam RET-700 features a dedicated retro-illumination mode. This allows the clinician to capture detailed images of opacities within the crystalline lens, making it an excellent tool for documenting cataract progression and educating patients.
The 3D auto-tracking system on the RET-700 automatically detects the position of the patient's eye and independently adjusts the machine's focus and alignment in the X, Y, and Z axes. This eliminates the need for manual joystick micro-adjustments, significantly speeding up the examination time and ensuring highly repeatable results regardless of the operator's experience level.
