PURPOSE: To describe a new technique that allows visualization of the posterior corneal surface, enabling safer performance of deep anterior lamellar keratoplasty. METHOD: Cadaveric porcine eyes are dissected using a 3 mirror Goldman lens and 30-gauge needle to achieve sub-Descemet cleavage plane. Histopathology of the dissections is also presented RESULTS AND CONCLUSION: The technique demonstrated in the video offers a novel method whereby substances such as air / viscoelastic can be injected in a controlled manner under continuous visualization. This would likely reduce the risk of needle penetration and may provide better sub-Descemet dissection in human eyes.
