5 Key Takeaways

• 1

  Scleral lenses induce mild corneal edema of about 2% in healthy eyes, but may cause epithelial and stromal edema in those with reduced endothelial cell density.

• 2

  In a study, keratoconus patients wearing scleral lenses for one year showed significant changes in corneal thickness and curvature, differing between those with and without ICRS.

• 3

  The KC-ICRS group experienced a 3.98% increase in superior corneal thickness, while the KC group showed no significant changes in corneal thickness over the same period.

• 4

  Long-term scleral lens wear resulted in anterior corneal flattening and region-specific curvature alterations, but did not adversely affect visual acuity in either group.

• 5

  The study emphasizes the need for individualized fitting and monitoring of corneal topography to enhance patient satisfaction and manage potential visual changes.
