Clinical Scorecard: Specialty Soft Design for Keratoconus
At a Glance
| Category | Detail |
|---|---|
| Condition | Keratoconus causing irregular astigmatism and visual impairment |
| Key Mechanisms | Corneal thinning and irregular astigmatism leading to distorted vision; specialty soft lenses designed to improve fit and visual acuity |
| Target Population | Patients with keratoconus intolerant to conventional contact lenses or seeking alternative lens options |
| Care Setting | Optometry or ophthalmology clinics specializing in contact lens fitting and keratoconus management |
Key Highlights
- Conventional corneal gas permeable lenses may cause discomfort and poor tolerance in keratoconus patients.
- Specialty soft contact lenses (e.g., KeraSoft Thin) can provide improved comfort, stable fit, and better visual acuity in keratoconus.
- Long-term use (8 years) of specialty soft lenses demonstrated sustained patient satisfaction and manageable disease progression.
Guideline-Based Recommendations
Diagnosis
- Confirm keratoconus diagnosis with corneal topography and slit lamp biomicroscopy.
- Assess keratometry values and manifest refraction to evaluate severity and astigmatism.
- Evaluate best-corrected visual acuity and pupil size.
Management
- Consider specialty soft contact lenses for patients intolerant to rigid gas permeable lenses.
- Use diagnostic fitting with specialty soft lenses and refine overrefraction to optimize visual acuity.
- Provide patient training on lens application and removal.
Monitoring & Follow-up
- Schedule follow-up visits to assess lens fit, comfort, and visual stability.
- Monitor for corneal health and any signs of compromise after lens removal.
- Adjust lens parameters as keratoconus progresses or if visual acuity changes.
Risks
- Potential discomfort or poor lens tolerance with conventional lenses.
- Risk of corneal compromise if lenses are not properly fitted or monitored.
- Progression of keratoconus and development of cataracts may alter lens requirements.
Patient & Prescribing Data
Adult keratoconus patients with intolerance to conventional gas permeable lenses
Specialty soft lenses can achieve stable, comfortable wear with improved visual acuity (20/20) and sustained use over years, with periodic parameter adjustments as disease progresses.
Clinical Best Practices
- Perform comprehensive ocular examination including corneal topography and keratometry before lens fitting.
- Start with diagnostic specialty soft lenses and refine fit and prescription based on overrefraction and patient feedback.
- Ensure lens movement and centration are adequate to maintain corneal health and comfort.
- Educate patients on lens care, insertion, and removal techniques.
- Schedule regular follow-ups to monitor ocular health and adjust lenses as needed.
