Objective:
To evaluate the use of impression-based scleral lenses in a patient with complex ocular surface disease, including Sjögren’s syndrome and advanced glaucoma.
Approach:
- Case Description: A 76-year-old female with a history of Sjögren’s syndrome, severe meibomian gland dysfunction, and advanced glaucoma was evaluated for therapeutic scleral lenses due to persistent ocular surface symptoms affecting her daily life.
- Outcome: After four months, the patient experienced significant improvement in ocular surface health, with corneal staining improving to grade 1 SPK in both eyes, reduced need for artificial tears, and improved visual acuity to 20/20 OD and 20/25 OS.
Key Findings:
- Initial scleral lens fitting improved acuity but caused discomfort.
- Impression-based design provided better ocular surface coverage and comfort.
- Redesigning the lens to an ovate shape improved usability for the patient.
- Final visual acuity was 20/20 OD and 20/25 OS at distance.
Interpretation:
Scleral lens success is determined not only by optical parameters but also by patient usability and comfort, as highlighted in the case.
Limitations:
- The case is based on a single patient experience with complex ocular surface disease, which may not be generalizable to all patients.
Conclusion:
In complex therapeutic cases, scleral lenses can restore independence when designed to meet the patient's functional needs and usability.
