Chinese Trial Validates Scleral Lenses

Large Chinese trial confirms strong visual outcomes with four-zone scleral lenses for irregular corneas

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.
