    14. In vivo evaluation of corneal biomechanical properties by optical coherence elastography at different cross-linking irradiances

      In vivo evaluation of corneal biomechanical properties by optical coherence elastography at different cross-linking irradiances
      Corneal collagen cross-linking (CXL) strengthens the biomechanical properties of damaged corneas. Quantifying the changes of stiffness due to different CXL protocols is difficult, especially in vivo . A noninvasive elastic wave-based optical coherence elastography system was developed to construct in vivo corneal elasticity maps by excitation of air puff. Biomechanical differences were compared for rabbit corneas given three different CXL protocols while keeping the total energy delivered constant. The Youngs modulus ...

  2. About Wenzhou Medical College

    Wenzhou Medical College

    Wenzhou Medical College, designated as a key university in Zhejiang, is an institution of higher learning under the leadership of Zhejiang Provincial Government. Its history can be traced back to Zhejiang Specialized Medical School established in Hangzhou in 1912, named "Zhejiang Second Medical College" at that time. In August 1958, part of Zhejiang Medical College was moved from Hangzhou to Wenzhou and began recruiting 5-year fulltime program students, hence the name Wenzhou Medical College (WMC).
