Scleral contact lenses offer superior comfort and vision for keratoconus patients compared to other lens types. While they reduce dryness, midday fogging remains a challenge for some wearers.
Area of Science:
- Ophthalmology
- Optometry
- Biomedical Engineering
Background:
- Keratoconus management often involves specialized contact lenses.
- Previous lens modalities may have limitations in comfort and vision for keratoconus patients.
Purpose of the Study:
- To evaluate the comfort and subjective experiences of keratoconic patients wearing scleral contact lenses.
- To compare these experiences with prior contact lens use.
Main Methods:
- Recruitment of 24 keratoconus patients.
- Informed consent and Institutional Review Board approval.
- Administration of a survey and a dry eye questionnaire.
Main Results:
- Overwhelming preference for scleral lenses' comfort and vision over previous lenses (soft, piggyback, hybrid, gas permeable).
- Patients reported reduced dryness with scleral lenses, despite some being dry eye suspects.
- Midday fogging occurred occasionally in over half of the participants.
Conclusions:
- Scleral contact lenses demonstrate excellent patient acceptance due to enhanced comfort and vision.
- These lenses can alleviate dry eye symptoms for many keratoconus patients.
- Midday fogging is a notable limitation requiring further investigation.
