角膜地圖儀

  小錐形測量頭設計,28個Placido環可覆蓋90%以上的角膜表面,世界上第一台採用”Arc-Step”方法計算來反映角膜真實曲率的地形圖儀,能精確的描繪角膜曲率、弧度、角膜屈光度形狀是否正常。具有精確、高重複性和顯示角膜地形最小细節的能力。

特色重點:

  1.  “Arc-Step”弧步演算法:可測量兩種曲率值:①傳統的Axial值(模擬球面曲率);②真實曲率true curnature(為OPTIKON獨有技術):最早獨創採用弧步演算法,這一演算法可顯示角膜每一局部點的曲率值,與傳統的軸向曲率方式比較,能更真實地反映角膜表面的形態。可即時顯示出角膜軸向的高度值,使相對高度的測量更精確。
  2. 凹陷式錐形測量頭和頂點距離控制技術(EPCS):獨有的凹陷式錐形測量頭和紅外線定位專利技術,自動識別角膜頂點來獲得圖像,對焦準確,角膜覆蓋面更大,角膜曲率測量範圍更廣。
  3. 移軸技術:自動校正偏心,無論是否對正正視軸,都可以準確測試,大幅降低檢測時間,並改善病人的不舒適性。
