Salient HFA3 .docx

Salient Characteristics The government has a requirement for a Humphrey Visual Field Analyzer system that benefits patients in the Eye Clinic. The Humphrey Visual Field Analyzer shall have the following features and characteristics:

Offeror must meet or exceed these specifications:

· Dimension: 46 L x 52 W x 58 H (cm) which is exactly equivalent to: 18.11 L x 20.47 W x 22.83 H (inch)

· Electrical Requirement: 100-120v- 50/60 Hz, 4.0A

· Internal Storage: 500 Gb

· Operating System: Windows 7-64 bit

· Fixation Control

· Video eye monitor

· Heijl-Krakau blind spot monitor

· Gaze Tracking

· Head Tracking

· Vertex Monitoring

· Visual Field Index™: Summary measurement of the patient’s visual field status, expressed as a percent of a normal age-adjusted visual field.

· Liquid Trial Lens™: Using Liquid pressure, delivers each patient’s refractive correction. Available correction range is -8 to +8 diopters. Spherical correction only. Liquid Trial Lens available in model 860 only.

· SmartTouch interface: Touch screen interface allows for a more efficient workflow

· RelEye: The RelEYE fixation monitoring system allows for systematic and

· pin point fixation inspection. The HFA 3 captures and keeps the image of the eye during the testing and just after, prior to the Result Review Screen. RelEYE cannot be viewed on the HFA 3 after terminating the test. Using the HFA 3, RelEYE is also available in FORUM Glaucoma Workplace (minimum version 2.0.3). Only FORUM can keep the RelEYE data stored for future usage for exporting exams. Guided Progression Analysis (GPA™): GPA allows the doctor to compare visual field status and progression to data collected from glaucoma subjects. GPA provides statistically significant change as well as rate of change, and predict future vision quality.

· Connectivity: For comprehensive connectivity the HFA 3 can be connected to FORUM (minimum version 3.2) with FORUM Glaucoma Workplace (minimum version 2.0.3). DICOM conformant as per the DICOM Conformant Statement, available at http://www.zeiss.com/meditec/en_us/products---solutions/ophthalmology-optometry/dicom.html HFA 3 also supports common file folder sharing used by most Electronic Medical Record Systems (EMR).SITATM (Swedish Interactive Threshold Algorithm): A patented algorithm for fast and accurate visual field threshold measurements; it is the most commonly used test strategy and incorporates patient responses in real time. SITA database: The SITA normative database contains normative data for SITA Standard and SITA Fast 30-2, 24-2 and 10-2 threshold visual field test results from healthy subjects aged 17 to 89.

· SITA-SWAP™ / Blue-Yellow Perimetry: Replaces the Full Threshold and

· FastPac strategies for testing SWAP visual fields due to the much shorter test times available when utilizing SITA SWAP

· STATPAC™: It is a software package using normative values and patient data to perform statistically analysis to help interpret test data. STATPAC is the software, normative data and statistical analysis in HFA.

· Kinetic Testing: In kinetic testing, light stimulus of fixed characteristics is moved into the visual field from a non-seeing area, until it is detected by the patient. Typically, the stimulus is brought toward the center from several directions and the operator marks the location at which the patient first detects the stimulus (threshold point). The HFA 3 provides a kinetic graphical interface with full 180º testing range.

· Glaucoma Hemifield Test (GHT): Compares points in the superior and inferior hemifield to provide analysis of test results. On 24-2 and 30-2 tests, the GHT evaluates five zones in the superior field and compares these zones to their mirrored zones in the inferior field. The GHT evaluates the severity of the GHT evaluates five zones in the superior field and compares these zones to their mirrored zones in the inferior field. The GHT evaluates the severity of disturbed points in each zone pair, relative to its normal database.
