Objective:
To analyze prescribing trends of scleral lenses in a high-volume contact lens clinic over a 6-year period, highlighting the implications for clinical practice.
Key Findings:
- 60.8% of lenses prescribed were mini-scleral designs, while 39.2% were large scleral designs.
- Mini-scleral lens usage increased significantly from 44% in 2016 to 74% in 2022, except in keratoplasty patients.
- 99.8% of scleral lenses had toric landing zones, reflecting the anatomical shape of the sclera.
Interpretation:
The shift towards mini-scleral lenses and the prevalence of toric landing zones indicate a response to the anatomical variations in scleral shape, enhancing fitting success and suggesting a need for updated fitting practices.
Limitations:
- Retrospective design may limit the ability to establish causation and introduce potential biases.
- Data limited to a single clinic in the Netherlands, which may affect generalizability.
Conclusion:
The study highlights a significant trend towards mini-scleral lens designs and emphasizes the importance of toric landing zones for optimal fitting, suggesting areas for future research.
