Objective:
To evaluate longitudinal variations in intraocular pressure (IOP) after long-term scleral lens wear in Chinese individuals with irregular and regular corneas.
Key Findings:
- Mean IOP variation was less than ±0.3 mmHg across study visits in both groups (P>.05).
- 10% of eyes in both groups showed a sustained IOP increase of ≥ 2 mmHg from baseline at two consecutive visits.
- Both groups exhibited similar IOP trends with an average variation of ≤ 0.6 mmHg over 3 months.
Interpretation:
IOP remained stable in Chinese individuals with regular and irregular corneas after 3 months of scleral lens wear, although some individuals experienced significant increases.
Limitations:
- Different tonometers were used for IOP measurement in the two groups.
- IOP variations were analyzed separately for ICG and RCG participants.
Conclusion:
Long-term scleral lens wear does not significantly affect IOP in the studied population, but further research is needed to assess IOP changes with lenses in situ and their potential effects on ocular health.
