Background

Scleral lenses are increasingly utilized for vision rehabilitation in patients with keratoconus and corneal transplants. However, improper fitting can lead to complications such as conjunctival compression and inflammation, necessitating careful lens design to match the ocular surface's shape.

Data Highlights

No numerical data or trial data presented in the article.

Key Findings

The patient experienced chronic irritation and a pyogenic granuloma due to poorly designed scleral lenses.
Profilometry-guided freeform lenses were ordered to match the individualized shape of the scleral surface.
Post-fitting, the patient achieved 20/20 vision in both eyes and reported comfort with the new lenses.
The pyogenic granuloma diminished significantly, and by the fourth pair of lenses, it had completely resolved.
Sequential lens modifications were necessary as the ocular surface changed during treatment.

Clinical Implications

Clinicians should consider profilometry-guided fitting to avoid complications associated with standard lens designs.

Conclusion

The successful resolution of the pyogenic granuloma and restoration of vision in this patient demonstrates the outcomes of profilometry-guided scleral lens design in accommodating the unique topography of the ocular surface.
