In this study published by David Kang from Korea the biomechanical changes after tPRK and fs-LASIK were compared. In addition, biomechanical corrected IOP was measured pre-operatively and 6 month post-operatively. The study showed that bIOP was statistically not different compared to the pre-op measurements.

New Study illustrates the clinical use of TBI for enhancing ectasia detection. In this groundbreaking paper the development and validation of the tomographic Biomechanical Index (TBI) is described. The data prove the increased sensitivity and specificity for the detection of subclinical keratoconus.

Prof Renato Ambrósio Jr, MD, PhD on the Advantages of Integrating Tomography and Biomechanics

Three important questions on corneal biomechanics, Prof Ambrósio gives the answers.

  • Can you give a brief update how to detect ectasia based on corneal biomechanics?
  • What is the advantage of integrating tomography and biomechanics?
  • What will be the future of screening for ectasia risk prior to refractive surgery?

Why is corneal biomechanical assessment essential before refractive surgery?

These and other questions regarding corneal refractive surgery will be discussed during the lunch seminar at DOC; Friday 15th of June from 2:00 to 3:30 pm. Experienced surgeons as Dr. Omid Kermani, Cologne and Dr. Lazlo Kiraly, Leipzig will share their experience regarding the topic: Current trends in modern refractive surgery: pre-operative diagnostics and treatment options.

Case series further illustrates the advantage of the biomechanical assessment in cases without topographic or tomographic abnormalities. In this case series 12 cases are presented without any tomographic abnormality in one eye but clear ectasia in the other eye. Biomechanical properties were already altered in the tomographic normal eyes.
