植入高階多焦點散光人工水晶體(PhysIOL FineVision Trifocal Toric IOL)，藉由威力揚定位系統(VERION Image Guided System)在手術中可精準植入高階多焦點散光人工水晶體，期待能達到最正確的手術矯正治療。植入高階多焦點散光的人工水晶體，如果沒有對準到視軸中心(Visual axis)，或是散光軸度(Astigmatism axis)沒有對準，將會使多焦點散光人工水晶體的效果大打折扣，相當可惜。

嬰幼兒童視力篩檢新時代來臨了-光導波折射驗光儀(ADAPTICA 2 WIN)
嬰幼兒童視力篩檢新時代來臨了-光導波折射驗光儀(ADAPTICA 2 WIN)
本診所於2017年6月購進專門檢查嬰幼兒童視力屈光度數的儀器-『光導波折射驗光儀』(ADAPTICA 2 WIN)，能檢測出3個月大至3歲的嬰幼兒視力狀況，提早發現弱視及斜視(Ambyopia/Strabismus)的可能，可以量出近視(myopia)、遠視(hyperopia)、散光(astigmatism)、瞳孔距離(pupil distance)、眼位注視…等數據。
檢查過程為全自動拍攝，由醫師親自操作，有音樂可以吸引小兒注意，成功率及準確度近98%。此檢查屬預防保健項目，因此健保並無給付，自費檢查費用約NT 1000元，檢查結束後會列印報告，供家長參考及保存。

The 2WIN main applications:
- Binocular refraction measurement in natural vision conditions.
- Refractive errors – Myopia, hyperopia, astigmatism and other amblyogenic factors. Un-aided binocular refraction of all other patients.
- Refraction of infants and children from 2 months of age, seniors, impaired and non-cooperative patients.
- Early detection and documentation of multiple amblyogenic factors. Un-aided binocular refraction of all other patients.
- Sight anomalies that may be related to anisometropia, anisocoria, strabismus, phoria.
- Pupil parameters – pupil size, pupil distance and head tilt.
- Automatic measurement of dynamic pupils response to programmable light stimulations.
- Over-refraction with glasses or contact lenses.
- Lens centering on spectacle frames.
Extended Range Refraction and Zoom [EZ-App]
The 2WIN measures spherical power in the range of -15D to +15D, being the only mobile, hand-held instrument to provide such extended measurement range.
The 2WIN measurement principle is eccentric photo-retinoscopy. InfraRed (IR) light is projected through the patient pupils and onto the retina. Depending upon the refractive error, the reflected light forms a specific crescent-shaped brightness pattern within the pupil. The 2WIN measures spherical power, cylinder power and axis by interpreting the reflected light crescent pattern and position.
Zoom of InfraRed Retinoscopy Images
Automatic zoom of InfraRed retinoscopy enables detection of artifacts due to other abnormalities (opacities such as cataracts, foreign bodies, etc.).
Corneal Reflexes Application [CR-App]
Thanks to the “Analysis of Corneal Reflexes”, the 2WIN can help your daily work by automating the analysis of refraction with a documented information of phorias and tropias (horizontal and vertical). This application provides complete information regarding the position of corneal reflexes.
Dynamic Pupillometry [DP-App]
Automatic measurement of dynamic pupil response to programmable light stimulations enables the detection of subtle pupillary changes, removing subjectivity from the pupillary evaluation.
Intermediate Distance Application [66cm-App]
Thanks to the 2WIN application “Intermediate Distance”, it is possible to identify the difficulties in focusing at VDUs Distance and to estimate the power of the additional lens needed on top of the prescription.
The 2WIN measures the patient’s refraction while reading from VDUs, at a distance of 66 cm (2’). In all those cases when reading at such distance proves difficult, the 2WIN calculates the necessary additional power (ADD) to restore the best vision. The application requires the use of an additional lens that is inserted in the central aperture of the 2WIN; the additional add-on lens together with a 66 cm reading chart compose the kit.
Lens Centering on Frames [LC-App]
This feature allows to accurately center spectacle lenses with reference to the actual visual axis of the eye (cornel reflex) for better vision comfort.
