Four months after the procedure, significant increases were observed in the first applanation time (&lt;i&gt;p&lt;\/i&gt; = 0.007), second applanation time (&lt;i&gt;p&lt;\/i&gt; &lt; 0.001), highest concavity time (&lt;i&gt;p&lt;\/i&gt; = 0.004), intraocular pressure (&lt;i&gt;p&lt;\/i&gt; = 0.009), and biomechanical-compensated intraocular pressure (&lt;i&gt;p&lt;\/i&gt; = 0.007). In addition, the absolute value of highest concavity delta arc length and stress-strain index showed a significant decrease after the LEB (&lt;i&gt;p&lt;\/i&gt; = 0.021 and &lt;i&gt;p&lt;\/i&gt; = 0.037, respectively). Other corneal biomechanical parameters did not show significant differences following the LEB procedure (&lt;i&gt;p&lt;\/i&gt; &lt; 0.05).Conclusions: The resection and repositioning of the fat pockets in LEB lead to biomechanical changes of the cornea in the direction of increasing corneal stiffness.<\/jats:p>","DOI":"10.3341\/kjo.2024.0093","type":"journal-article","created":{"date-parts":[[2024,12,24]],"date-time":"2024-12-24T03:07:32Z","timestamp":1735009652000},"page":"31-40","update-policy":"https:\/\/doi.org\/10.3341\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["The
