Which Lens Wins in Keratoconus?
This study reveals how choosing the right contact lens can significantly enhance visual outcomes for keratoconus patients.
Clinical Scorecard: Which Lens Wins in Keratoconus?
At a Glance
Category Detail
Condition Keratoconus Key Mechanisms Comparison of visual outcomes between mini-scleral lenses and small-diameter rigid GP lenses. Target Population Individuals with moderate-to-severe keratoconus. Care Setting Tertiary referral center.
Key Highlights
Both lens types significantly improved best-corrected visual acuity (BCVA). RGP lenses showed lower surface regularity index and irregular astigmatism index. Topographic indices like CSI and IAI are valuable for lens fitting decisions. SLs are beneficial for eyes with apical scarring or highly decentered cones. Study suggests incorporating topographic indices into fitting algorithms. Guideline-Based Recommendations
Diagnosis
Use topographic indices for diagnosing keratoconus and predicting visual improvement. Management
Consider RGP lenses for patients with lower CSI values and SLs for those with apical scarring. Monitoring & Follow-up
Regularly assess visual acuity and keratometric values post-lens fitting. Risks
Potential selection bias and overrepresentation of advanced keratoconus in study. Patient & Prescribing Data
36 eyes from 28 patients with moderate to severe keratoconus.
SLs are particularly advantageous for patients with apical scarring.
Clinical Best Practices
Incorporate topographic indices into contact lens fitting algorithms. Utilize fluorescein staining for SL fitting to ensure proper lens fit. References
