5 Key Takeaways

• 1

  A clinical trial in China showed that a four-zone scleral lens design effectively rehabilitates vision in patients with irregular corneas.

• 2

  The study involved 138 adults with irregular corneas, primarily due to keratoconus, and followed them for three months after lens fitting.

• 3

  At one month, 97.7% of participants met the criterion for successful visual rehabilitation, with a median improvement of 0.30 logMAR.

• 4

  Fitting efficiency was high, requiring an average of 1.5 lenses per eye, with only 5% needing two refits during follow-up.

• 5

  No serious adverse events were reported, and safety findings indicated stable endothelial cell density and intraocular pressure throughout the study.
