When it comes to managing keratoconus, choosing between scleral lenses and rigid gas permeable (RGP) contact lenses can make a dramatic difference in vision clarity, comfort, and daily quality of life. At Dr. Amit Jain’s clinic in Dubai, we specialize in customizing both lens types to your unique corneal shape, leveraging advanced diagnostics like corneal topography.
Understanding the Options
Rigid Gas Permeable (RGP) Contact Lenses
- Made of firm, oxygen-permeable material, these lenses rest directly on the cornea (en.wikipedia.org, med.aws.emory.edu).
- They mask corneal irregularities by creating a smooth optical surface.
- Ideal for mild-to-moderate keratoconus.
- Advantages include high oxygen transmission and lower initial cost.
- Disadvantages: may cause discomfort and are prone to dislodging.
Scleral Lenses
- Larger lenses that vault over the cornea and rest on the sclera, creating a tear-filled reservoir.
- This fluid cushion smooths out irregularities for superior visual clarity.
- Scleral lenses are preferred for advanced or irregular keratoconus (en.wikipedia.org.
- Benefits include:
- High comfort due to minimal eye contact.
- Stable fit with little movement and excellent acuity.
- Suitable for eyes that are dry or sensitive (med.aws.emory.edu).
Head-to-Head Comparison
| Feature | Scleral Lenses | RGP Lenses |
|---|---|---|
| Comfort | Very high, rests on the sclera | Moderate, rests on the cornea |
| Visual Acuity | Superior in advanced KC | Excellent in mild-moderate KC |
| Stability | Minimal movement | More prone to dislodging |
| Oxygen Transmission | High but slightly less than RGP | Very high |
| Fit Complexity | Custom design, specialist required | Standardized, easier fit |
| Cost (Initial) | Higher | Lower |
| Adaptation Time | Longer | Shorter |
🗓 When to Choose Each Lens
RGP Lenses Are Best For:
- Early-stage keratoconus.
- Patients seeking a cost-effective solution with quick adaptation.
- Those comfortable with standard lens care and handling.
Scleral Lenses Are Ideal For:
- Advanced or irregular keratoconus, where RGP fails
- Individuals needing maximum comfort, hydration, and stability .
- Patients with sensitive or dry eyes, due to the tear reservoir feature .
Real-World Evidence
💡 Things to Consider
- Cost: While scleral lenses are pricier initially, they are durable (lasting 1–3 years) and can be more cost-efficient long-term.
- Maintenance: Both require meticulous cleaning; scleral lenses and their fluid reservoir need daily cleaning and soaking.
- Specialist Fitting: Accurate fitting is crucial—only experienced practitioners like Dr. Amit Jain can ensure the right fit and eye health.
FAQs: Voice Search Ready
1. Which is better for keratoconus, scleral or RGP lenses?
For advanced cases, scleral lenses offer better comfort, vision, and stability. RGP lenses are suitable for early-stage keratoconus.
2. Are scleral lenses worth the extra cost?
Yes—especially if you need better vision, comfort, and fewer complications compared to RGP or soft lenses.
3. Can I switch from RGP to scleral lenses?
Absolutely. Many patients transition successfully to scleral lenses for improved results.
4. How long do scleral lenses last vs. RGP lenses?
Both types typically last 1–3 years with proper care.
5. Do scleral lenses hurt when inserted?
Initially, using a lens inserter helps. After a short learning curve, most find them comfortable
6. Is scleral lens fitting available in Dubai?
Yes—Dr. Amit Jain specializes in custom scleral lens fitting for keratoconus in Dubai.
7. Can scleral lenses protect against corneal scarring?
Yes—the vaulting design protects the cornea from further damage and can reduce progression toward transplantation.
Final Verdict
For mild to moderate keratoconus, RGP lenses remain a reliable and affordable first choice. However, for advanced cases, intolerance issues, or irregular corneas, scleral lenses are the superior option, offering enhanced comfort, visual stability, and protection.
