Emmetropic Eye 0.00 Dioptersspot pattern of light is uniform

Hyperopic Eye +4.24 Dioptersspot pattern of light is compacted

Examples of Spot Pattern Received Through CCD Camera

Light is sent from an illumination source inside the SureSight through a beamsplitter and focuses on the back of the eye (retina). The retina, in turn, reflectsthe light back into the device. Inside the unit, the beam travels through a seriesof mirrors and is received by a micro-lens array, creating an image which is sentto a CCD camera. The spot pattern of light formed is translated into sphere,cylinder, and axis.

VISION SCREENER OPTICAL SYSTEM ARCHITECTURE

The following is a description of the present design architecture. A collimated beam of light is projected outof the patient port by the illumination system. The light is ‘focused” by the eye lens and cornea to a smallspot on the retina. This blur acts as a point source on the back of the eye which then radiates back throughthe eye lens and cornea producing a reflected beam which includes information about the lens power andeye aberrations. The resulting return beam is directed by the beam splitter into the measurement path whichis detected by the camera at the end of the path. To achieve alignment, the practitioner views the patienteye and the alignment guide pattern through the viewing system. The working distance between the outputport of the device and the patient of approximately 40 centimeters. This large working distance provides theopportunity to improve accuracy in children, as well as being less intimidating to them. It also reduces theneed for fogging in which is used in conventional autorefractors which work at approximately 2cm.

PN 140399 Rev. B 8

MAJOR SUBSYSTEMS:

Illumination System:The illumination system generates a laser beam which can be projected into the eye under test.

Because this laser beam radiates in the infrared region - it is not visible without an IR goggle or other IRdetecting device. For repair and calibration purposes, an ITT night vision scope is recommended for anywork which includes the illumination system.

The source of illumination is a 5 mW electrical, 3 mW optical semiconductor laser located on thelaser mini board. This board is attached to the illumination tube which houses the optics needed to collectthe light emitted by the laser and form it into a beam which is projected from the end opposite the laser. Thelaser mini board is connected via a 4 position flex cable to the laser drive board which controls the laseroutput. The drive system monitors the laser output with a photodiode which is physically built into the laserdiode. The laser drive system controls the laser output to a particular photodiode level which is set by theDSP board. The DSP controls this setting with a digital pot on the laser drive board according to acalibration performed at the factory. This beam is transmitted through the beam splitter located near the oneinch port on the front of the unit.

*SAFETY NOTE: While the laser is capable of emitting 3 mW of optical power, only a fraction exitsthe illumination tube. Laser levels are controlled to approximately 18 µW, which is well within Class I safetylimits. However, to prevent improper exposure DO NOT look at the bare laser diode.

A properly functioning illumination system produces an approximately collimated beam of light 2mmin diameter. This beam can be seen using ITT goggles when a piece of white paper is placed in front of anoperating illumination tube. The collimated aspect of the beam can be observed by the lack of change insize of the beam (spot) regardless of the distance from the front of the tube.

Measurement System:The measurement system detects the beam reflected from the patients eye back toward the unit.

This beam enters the product through the one inch port on the front of the unit and is reflected down towardthe bottom of the unit by the reflecting side of the beam splitter. This beam passes through a first conjugatelens, to two measurement mirrors which bend the beam across the bottom of the unit and back up towardthe top where it passes through a second conjugate lens in to the camera/lenslet assembly. Thecamera/lenslet assembly consists of the camera board with a lenslet filter mounted to the top of it by alenslet housing. When the beam passes through this lenslet and IR filter, a group of spots are created whichrepresent the optics of the eye from which the beam came.

The camera image is progressively sent to the DSP board for processing. If a sufficient number andquality of images is detected, the DSP computes and reports a reading of the optical power detected. Theexposure, gain and other settings of the camera are controlled by the DSP board through a serial port and adigital pot on the camera board. These settings are also set during the factory calibration.

Viewing System:The purpose of the viewing system is to create a visible image which can be used to align the

product with the patient. Because the laser is invisible, it can not be used for aligning. Instead, the viewingsystem produces a visible crosshair target which is aligned so as to be in the same position as the invisiblelaser beam at the in-range working distance. In this way, when the practitioner aligns the crosshair with thepatients eye, they are also aligning the laser which is required to make the measurement. It is critical thatthe viewing crosshair be aligned to the laser beam at the proper working distance.

The source of illumination for the viewing system is an LED located on the LED mini board. This is atraditional LED used to backlight a crosshair which is cut into a cup mounted over the LED. This mini boardand cup assembly is mounted to one end of the viewing tube which contains optics required to magnify andproject the crosshair to the patients position 40 cm away. The LED mini board is connected to the laserdrive board through a 4 position flex cable. The actual drive for the LED is on the laser board and is turnedon and off by the DSP using a single control line.

PN 140399 Rev. B 9

PC BOARD ASSEMBLIES:

DSP Board:The DSP board includes the microprocessor which controls the operation of the product. It also

contains the software in a flash EEPROM, external RAM, a real time clock with battery, and the decodingcircuitry for the user button presses. In addition, the DSP board “passes” both power and control signalsbetween boards. All boards are connected to the DSP and all signals and power are redistributed asneeded. In other words - any connections which must be made between boards do so through the DSPboard.

Power Board:The power board includes two switching systems to generate all voltages required to operate the

product. It includes the charging control circuitry, the low battery circuitry, the distance measurementcircuitry, and the speaker/tone generation circuitry.

Fixation Board:The fixation board includes the fixation LED array which is flashed to attract the patients attention. It

also includes the jacks for USB/RS232 connection, and the charging port. The drive circuitry for the RS232and USB is located on this board, as well as the IRDA sensor which communicates with the printer. In thecentral section of this board, the ultrasonic sensor is mounted. However, the ultrasonic sensor circuitry isactually on the power board, it only sits on the fixation board to match the output port of the housing.

One important note: the fixation board must be present for the system to power up. If the powerboard does not sense the presence of the charging jack with no plug present (i.e.: not charging), it will notpower up.

Laser Board:The laser board provides the drive for both the viewing crosshair LED and the laser. The LED is

controlled with a simple on/off control at a set output current. The laser is controlled to a target leveldepending on the setting of the digital pot on this board. The pot is settable by the DSP during each startupof the device. In addition, the laser has an on/off control which is used in addition to the digital pot to insurethat the laser is off when not required for measurement.

Camera Board:The camera board contains a full chipset for the black and white imager which detects the return

beam for measurement. The camera exposure control is accomplished via a serial port on the board, andthe gain is controlled by a digital pot which is settable by the DSP. The camera gain is subject to calibrationat the factory.

LCD:The LCD is a custom assembly of glass and printed circuit board. In addition to a series of seven

segment displays to present the reading results, and various indicators to indicate other conditions, thisboard includes the button inputs, and the dip switch inputs. Theses are passed to the DSP for detection anddecoding.

Laser Mini:The laser mini is a board which is primarily a mechanical mount. The board includes only the laser

diode and a flex connector which mates it to the laser drive board via a flex cable.

LED Mini:The LED mini is a board which is primarily a mechanical mount. The board includes only the LED

and a flex connector which mates it to the laser drive board via a flex cable.

Notes:Due to the large variation in parameters which determine the refractive values, (sphere/cylinder

variation from lens value, distance to wheel, exact alignment to lens center, unaccounted foraberrations in lenses, ND power variation, retinal material variation, fake eye actualdimensions, etc) deterministic methods do not yield expected values with an acceptabledegree of accuracy. Consequently, boundaries require correlation to positive clinicalperformance, and are not deductively linked to the lens value placed in the wheel position.

To revise or reset boundaries if tester or wheel are changed, there are two possible means. Fiveor more units can be tested five times to determine range of values, and then clinicallyverified to provide proper performance. Since this is very time consuming, the alternative isto test 30 units under the current settings and then use them to reset and or reverify theacceptable range of values under the new setup. During this comparison, standard deviationsof the new setup must be sufficiently low so as to allow new boundaries to be set. Forreference, a current set of wheel values including standard deviations is included in the wheelverification Aspec listed on the BOM.

GENERAL___________________________________________The purpose of this specification is to provide the product requirements for alignmentfor the SureSight product. The process aspec is derived based on these specifications,and the actual magnification and camera selected for use in the alignment stationtooling. In addition, a specification for the manufacturing setting is listed in addition tothe final product requirement. In each case, the manufacturing specification is tighterthan the final product specification. This is to insure that the manufacturing setting plusthe repeatability variation do not exceed the final product requirement. It should benoted that if the final product requirement is used for the manufacturing setting limits -excessive fallout would be likely at the final tester due to variations in repeatability.

Unless otherwise specified:• Fake eyes to be built as per Fake Eye Construction Aspec on BOM. Nominally this

includes a 4.5mm pupil. (ref)• All measurements to be completed at nominal working distance = 360mm from first

conjugate surface to front surface of fake eye.

1. MAXIMUM GLAREAll alignments to be done with fake eye positioned for maximum glare. Maximum glareoccurs when the laser is projected into a fake eye in the center and perpendicular to thelens. This demonstrated by achieving the brightest glare within the image. In general,this will also occur roughly in the center of the return image. See Figure 1.

Figure 1


A A04260 B


2. BEAM SPLITTER/CAMERA ALIGNMENTThe purpose of the beam splitter alignment is to place the return image in the center ofthe camera active area. This insures that the margin of aiming is as equal as possiblein the up, down, right, and left directions. For example, if the beam splitter image isaligned toward the top of the camera active area, any slight aiming above this will dropthe image off the camera - resulting in no readings.

To facilitate measurement of the image position, a green box function is projected bythe software in the exact center of the camera active area, and in a size whichrepresents the 4.5mm image. For reference, the camera active area is 696 by 494pixels. The green box is 300 by 300 pixels, and positioned with a center of 348,247 tocorrespond with the center of the active area.

Image position accuracy is measured in number of lines outside the green box. Giventhe pitch of the lenslet, each line outside the box corresponds to 1mm of offset in theposition of the center of the image compared to the center of the camera active area.

Figure 2


A A04260 B


Row MeasurementThe measurement of rows outside the box on any side is as follows:Only rows which are three or more spots are considered a row.If the row sits on the green line, it is counted as a half row. If the row is fully outside the line, it is counted as a full row.Figures 2 shows some examples of row counts.

A A04260 B


The purpose of the mirror alignment is to place the crosshair image on top of the laserat the nominal working distance. This insures that the when the physician aligns thecrosshair with the patients pupil, he is also aligning the laser to the pupil. This isnecessary because the laser is not visible and can not be aligned without an alternatemeans.

As noted below, the alignment station setting specification is .41 mm from the pixelcenter. This is to insure that it will meet the crosshair product specification of .76mmfrom the center of the pupil. When unit is initially shipped to the field, Repair Stationsare allowed a modest increase beyond this to cover plate to plate variation which is 1-2pixels (typical).

For convenience, crosshair position accuracy can be measured in pixels from pupilcenter. The equivalent specifications in pixels for the alignment station as well as forthe final tester are listed below.

The acceptable limit for the number of pixels the crosshair center can be from the pupilcenter is a function of the magnification of the optics as well as the resolution of theobserving camera. Any alteration of camera or magnification would require revision tothese specifications. The procedure for determining the magnification as well as thenumber of pixels within the product specification is listed in the next section.

A A04260 B


4. MAGNIFICATION MEASUREMENTThe purpose of the magnification measurement is to determine the pixels per millimeterof a particular optical/camera setting. This magnification is multiplied by thespecification in millimeters to convert to specifications in pixels for that station.

Procedure:1. Place a metric ruler as close to the plane of the fake eye pupil as possible and

placed across the pupil so that the numerical labels on the ruler can be seen for atleast 30 mm. The ruler tick marks should be clearly visible and the ruler should beas straight as possible.

2. Using FPGEYE software, grab a picture of the ruler and save the image.3. Open the image using Vision Builder, PC Paint or equivalent. 4. Count the number of pixels which are visible over a 30mm span of the ruler.5. Compute this number/30 to determine pixels per mm magnification.

GENERAL______________________________________These revision logs are maintained for reference, and do not contain every singlechange which has been made to this product. It is intended to provide a list of majorchanges which are relevant to the repair and troubleshooting of units. Any criticalproduct traceability should be done through the Welch Allyn ECR documentation.

Unless otherwise specified:• All changes refer to both eyecare and primary care units. S/N’s for each model are

given in the S/N log.• S/N’s and Dates refer to best estimate of implementation. Units which are very

close to this transition may or may not have been run to the new change and shouldbe checked for compliance. An estimate of 2 weeks, or 20 units would be anexpected potential overlap.

• It is the judgment of the ECR originator through the ECR process to determine if achange merits inclusion on this list. Changes may also be added after the ECR aslong as the relevant dates and S/N’s are supplied.

• Changes are noted under each category that they impact. Most will occur in at leasttwo categories.
