Background: Measuring cornea thickness is an essential parameter for patients undergoing
refractive Laser-Assisted in SItu Keratomileusis (LASIK) surgeries.
Discussion: This paper describes about the various available imaging and non-imaging methods
for identifying cornea thickness and explores the most optimal method for measuring it. Along
with the thickness measurement, layer segmentation in the cornea is also an essential parameter for
diagnosing and treating eye-related disease and problems. The evaluation supports surgical planning
and estimation of the corneal health. After surgery, the thickness estimation and layer segmentation
are also necessary for identifying the layer surface disorders.
Conclusion: Hence the paper reviews the available image processing techniques for processing the
corneal image for thickness measurement and layer segmentation.
