Abstract Details


To investigate the corneal morphology after ReLex SMILE in low, medium, high myopia and myopic astigmatism with Swept Source optical coherence tomography (SS OCT) images.


University Hospital of Lord�â�€�™s Transfiguration, partner of Karol Marcinkowski University of Medical Sciences in Poznan


Assessment of 100 eyes from 50 patients with myopia ranging from -1D to -10D and myopic astigmatism from -0.25 to -5D was performed preoperatively, 1 day, 7 days, 2 and 6 months after SMILE surgery. All SMILE procedures were performed by the same surgeon with the same laser parameters (energy-index 28~140nJ, spot distance -4,5 �Â�µm �â�€�“ lenticule, cap; spot distance 2 �Â�µm - side cut) using VisuMax 500 kHz femtosecond laser. Each patient underwent corneal SS OCT in 12 meridians of 6mm width using 3D DRI OCT Triton, Topcon preoperatively and postoperatively 1 day, 7 days, 2 and 6 months


Elevated cap thickness caused by swelling and inflammatory infiltration was gradually decreasing from day 1 to 6 months after surgery.Gradually decreasing of reflex interface intensity from day 1 to 6 months after surgery.Bowman layer distortion after high myopia correction.Bowman layer distortion after cap creation of 110�Â�µm thickness


Gradually decreasing of cap thickness and reflex interface intensity from day 1 to 6 months after surgery is associated with improving refractive outcomes after SMILE surgery. Corneal caps of SMILE are characterized by a good predictability and uniformity.Above evaluation show great SS OCT usability in cornea imaging and monitoring after SMILE surgery.
