A novel corneal indentation device for comparison of corneal tangent modulus before and after FS-LASIK in vivo. [PDF]
Biomed Eng OnlineBackground: Corneal refractive laser surgery is widely used to correct myopia and astigmatism due to its safety and effectiveness. However, postoperative changes in corneal biomechanics, such as corneal ectasia, can occur, necessitating a deeper ...

Journal of Ophthalmology, Volume 2025, Issue 1, 2025.Aims: To investigate the impact of horizontal markings on the VisuMax surgical bed headrest on the accuracy of astigmatism correction in small incision lenticule extraction (SMILE). Methods: This retrospective study categorized preoperative astigmatism severity into low‐astigmatism (−0.25 to −1.75 D) and moderate‐to‐high astigmatism (−2.00 to −4.50 D).

Corneal Epithelial Thickness Mapping: A Major Review
Journal of Ophthalmology, Volume 2024, Issue 1, 2024.The corneal epithelium (CE) is the outermost layer of the cornea with constant turnover, relative stability, remarkable plasticity, and compensatory properties to mask alterations in the underlying stroma. The advent of quantitative imaging modalities capable of producing epithelial thickness mapping (ETM) has made it possible to characterize better ...
