Scleral Trends: Mini-Scleral Designs and Toric Landing Zones
Discover insights from a recent retrospective study on prescribing trends in a high-volume Netherlands-based contact lens clinic, revealing a shift towards mini-scleral designs and the use of toric landing zones.
Clinical Report: Scleral Trends in Mini-Scleral Designs and Toric Zones
Overview
A retrospective study from a high-volume Netherlands clinic reveals a significant shift in scleral lens prescribing trends from large-diameter to mini-scleral designs over six years, with a notable prevalence of toric landing zones. The findings underscore the importance of adapting lens designs to anatomical scleral shapes for optimal fitting.
Background
The evolution of scleral lens designs is crucial for improving patient outcomes, particularly for those with irregular corneas. Understanding these trends helps clinicians make informed decisions about lens selection, which can enhance comfort and visual acuity. The study highlights the growing preference for mini-scleral lenses, which may offer better fitting characteristics.

Key Findings
60.8% of scleral lenses prescribed were mini-scleral designs.
Use of mini-scleral lenses increased from 44% in 2016 to 74% in 2022.
99.8% of scleral lenses fitted utilized toric landing zones.
The tangential-to-curved landing zone ratio was 10:1 in mini-scleral lenses.
The median age of patients at initial lens order was 43 years.
Successful fitting required an average of 1.4 lenses across all designs.
Clinical Implications
Clinicians should consider the increasing trend towards mini-scleral lenses and the necessity of toric landing zones when fitting patients. This approach aligns with the anatomical variations of scleral shapes, potentially improving patient comfort and lens stability.
Conclusion
The shift towards mini-scleral lenses and the widespread use of toric landing zones reflect advancements in fitting practices that cater to individual anatomical needs. These trends are essential for optimizing patient care in scleral lens fitting.
