    7 Quick user guide Register your 2WIN: registration takes less than 1 minute! It's highly recommended to register your 2WIN at: http://www.adaptica.com/user-registration/ Important • Read carefully the Chapter 6 – Precautions of the present manual before operating the device. • The 2WIN is a binocular refractometer and vision analyser. It measures refraction of both eyes at the same time, at the distance of 1 meter.

  • Page 16: Main Applications

    • It automatically measures binocular refraction, pupil distance, pupil size, direction of gaze, and fixation abnormalities. 7.2 Main Applications • Refraction of infants and children from 2 months of age, seniors, impaired and non- cooperative patients. • Early detection and documentation of multiple amblyogenic factors. •...

  • Page 19 • If you wish to refract infants, young children and any non-cooperative patients, you can turn the audible and/or the visible fixation targets ON. Audio fixation (attraction system) is preferable to the visible small lights fixation. • Make sure the Reliability Index of the refraction measurement is higher than 6 (max. is 9).

  • Page 20: Description Of The Device

    8 Description of the device 8.1 2WIN The measuring principle of the device is based on infrared photorefraction. In this technique, infrared light is projected through the pupils of the patient onto the retina. Depending on the refractive error, the reflected light forms a specific crescent-shaped brightness pattern within the pupil.

This information is used in particular to compensate accomodation in young patients with hyperopia-based refraction error.

  • Page 43: Preparation Of The Patient

    Browsing mode: recall of a possible patient. When pressing the left arrow button the patient's data is shown overlaying the image for a couple of seconds. The following data are displayed: patient number, patient name, date of birth, age selection, folder name, exam date and software version used to acquire and save the exam.
  • Page 44 Measurement tips: usually the RED condition depends on a bad distance between the 2WIN and the patient. When the top bar is RED adjust the distance between the 2WIN and the patient in order to focus the image and to obtain a GREEN top bar. Try every time to focus as best as you can, looking at the corneal reflex.
  • Page 45 5. When the top bar is PERMANENTLY green and the focusing indicator reaches the highest peak (as shown in the following photo) release the BUTTON S1/S2. Examination screen – focus OK 6. Stay firmly in the condition in which the upper bar is green until the message DATA PROCESSING appears on the display.
  • Page 46 Wait until the measurement process is finished and the results of the measurement are displayed on the screen. A two-beep sound indicates that the measurement has been correctly taken (this is an option selectable from Measurement>Sound>Alerts>Ending Beep). • If the ambient light is too high a message will appear warning about the unsuitable condition.
  • Page 47 Possible anisocoria For any problem during operation, please refer to Chapter 21 - Troubleshooting. 7. At the end of the measurement the results are displayed: Measurement screen The results of the measurement are here described. The top box contains, for OD and OS respectively, the values for sphere and cylinder, the axis and the “reliability index”, a number between R1 to R9 (the higher the index, the more reliable the measure).
  • Page 48 PD = pupillary distance HT = inclination of the line connecting the centres of the two pupils, referred to the ground Axis angles are expressed according to TABO system. Numbers for “Pupil” and for “Gaze” represent, for OD and OS respectively, pupil diameters and horizontal and vertical (in this order) offset angles of the average position of the corneal reflex on respect of the centre of the detected pupil.

    10.9 Zoom function When the measurement is performed, the operator can make a zoom on the acquired pupils of the patient. In order to do that SHORT PRESS the PRINT button. In order to come back to the main visualization just short press the power botton. The Zoom App has two main functions on the bottom left of the screen: the Zoom function (lens) and the Pan function (hand).
  • Page 50 If you hold the down button the zoom will became 1x, if you hold the up button the zoom will became 4x centered on the selected pupil. If you want to change pupil you have to press the right and the left buttons that allows you to choose on wich of the two pupils the zoom will take place.
  • Page 51 How to activate zoom on other measures You can use the Zoom App on an image took from another measure by selecting the Zoom function and loading the image. The Zoom App sometimes does not automatically identify the pupils. Auto-research of pupils In case of automatically identifying of the pupils, the situation will be the same as the nor- mal situation shown earlier.
