Objective:
To rehabilitate a patient with a failing penetrating keratoplasty graft using a customized scleral lens.
Key Findings:
- Best-corrected visual acuity (BCVA) improved from hand motion to 20/150 after 4 weeks.
- Subjective symptoms such as glare and fluctuating vision decreased.
- Tomography showed reduced central corneal thickness and improved epithelial contour.
Interpretation:
Maximizing oxygen permeability is critical for maintaining corneal clarity and prolonging surgical intervention in cases of endothelial decompensation.
Limitations:
- Single case report limits generalizability.
- Long-term outcomes and potential complications were not addressed.
Conclusion:
Combining high Dk material with a customized lens design provided therapeutic and visual benefits, aiding in the preservation of a failing PK graft.
