What Are Mini Scleral Lenses?
Mini scleral lenses are a smaller type of scleral contact lens designed to treat vision problems caused by irregular corneas, such as keratoconus, corneal ectasia, or post-surgery corneal distortion.
Like standard scleral lenses, mini sclerals vault over the cornea and rest on the white part of the eye (the sclera). However, they are smaller in diameter, usually between 14.5mm and 18mm, while full scleral lenses can range from 18mm to 24mm.
Mini scleral lenses still provide the same comfort, stability, and hydration, but their smaller size makes them easier to handle and fit for many people.
Features of Mini Scleral Lenses
Here are the standout features that make mini scleral lenses unique and effective:
1. Smaller Diameter
Mini sclerals are slightly smaller than full scleral lenses.
- Diameter: 14.5mm – 18mm
- This size makes them easier to insert and remove.
- The smaller design still covers the cornea but touches less of the sclera, giving a lighter feel.
2. Vaulting Design
Mini sclerals are built to vault over the cornea completely, creating a fluid reservoir of sterile saline between the lens and the eye.
- This fluid cushion smooths out irregular corneas.
- It keeps the eye hydrated and comfortable throughout the day.
- It also protects the cornea from friction or scratches.
3. Rigid Gas Permeable Material
Like full scleral lenses, mini sclerals are made of highly breathable materials that allow oxygen to pass through to the cornea.
- This keeps the eyes healthy and prevents dryness.
- It’s also safer for long-term wear compared to traditional soft lenses.
4. Custom Fit
Each mini scleral lens is custom-made to fit the exact shape of your cornea and sclera.
Eye specialists use digital corneal mapping to create a lens that matches your eye perfectly, ensuring top comfort and visual clarity.
5. Stable Vision
Because they cover more surface area than regular gas-permeable (RGP) lenses, mini sclerals stay very stable on your eye. They don’t move or pop out easily, giving you consistent, sharp vision all day long.
6. Hydrating Cushion
The liquid layer underneath the lens acts as a built-in moisturizer.
This helps reduce dryness, redness, and irritation, making them a great choice for people with dry eye disease or sensitive corneas.
Common Uses of Mini Scleral Lenses
Mini scleral lenses are used to solve several corneal and vision-related problems. Here are the most common uses:
1. Keratoconus
Mini sclerals are a popular choice for people with mild to moderate keratoconus.They create a smooth optical surface and provide clear, stable vision even if the cornea is cone-shaped.
2. Post-LASIK or Corneal Surgery
If someone has had LASIK, PRK, or corneal transplant surgery, their cornea may become irregular. Mini scleral lenses help restore normal vision by covering those irregularities safely and comfortably.
3. Dry Eye Syndrome
The fluid reservoir under the lens keeps eyes hydrated and prevents irritation, perfect for people who experience chronic dry eyes.
4. Astigmatism or Irregular Corneas
People with irregular astigmatism often struggle with soft lenses. Mini sclerals provide a stable, centered surface that corrects astigmatism effectively.
5. Eye Protection
Since mini scleral lenses don’t touch the cornea, they act as a protective shield, reducing the risk of scratches and further damage in sensitive eyes.
Who Can Benefit from Mini Scleral Lenses
Mini scleral lenses are an excellent solution for patients who:
- Mini scleral lenses create a smooth optical surface for clearer vision when glasses or soft lenses cannot correct your sight.
- The fluid layer under the lens keeps your eyes hydrated, providing relief from dryness and irritation throughout the day.
- These lenses help patients recover clear, stable vision following procedures like LASIK or corneal transplants.
- Mini scleral lenses offer a comfortable alternative for those with sensitivity or discomfort from standard contact lenses.
- Custom-fit mini scleral lenses stay securely in place, providing consistent, reliable vision all day.
