How Do Scleral Lenses Differ From Regular Contact Lenses?

For individuals seeking clear, comfortable vision correction, contact lenses are a popular and effective solution. However, not all contact lenses are the same. Among the different types available, scleral lenses offer unique benefits, particularly for individuals with specific eye conditions or those who struggle with standard contact lenses.
 

What Are Scleral Lenses?

Scleral lenses are large-diameter, rigid gas-permeable lenses that cover not just the cornea (the clear front surface of the eye) but extend over the sclera, the white part of the eye. These lenses create a tear-filled reservoir between the lens and the cornea, providing exceptional comfort and hydration.
 

Key Differences Between Scleral Lenses and Regular Contact Lenses

1. Size and Fit

• Regular Contact Lenses: Typically, soft or rigid lenses are designed to sit directly on the cornea. These lenses are smaller in diameter, generally ranging from 8-14 millimeters.

• Scleral Lenses: With a diameter of 14-20 millimeters, scleral lenses vault over the cornea and rest on the sclera. This design minimizes direct contact with the sensitive corneal tissue.
   

2. Comfort Level

• Regular Contact Lenses: While comfortable for many, standard lenses can cause irritation for individuals with dry eye, keratoconus, or irregular corneas.

• Scleral Lenses: The fluid reservoir beneath scleral lenses keeps the eye hydrated, providing relief for those with dry eye syndrome or other corneal conditions. The lack of direct corneal contact also reduces irritation.
   

3. Purpose and Use

• Regular Contact Lenses: Best suited for correcting common refractive errors like nearsightedness, farsightedness, and astigmatism in individuals with normal corneal shapes.

• Scleral Lenses: Specifically designed for individuals with irregular corneas, advanced keratoconus, severe dry eye, post-surgical complications, or conditions such as Stevens-Johnson syndrome or Sjögren’s syndrome.
   

4. Durability and Maintenance

• Regular Contact Lenses: Soft lenses need daily or monthly replacements depending on the type, while rigid lenses are longer-lasting but require careful handling.

• Scleral Lenses: Made from durable gas-permeable materials, scleral lenses can last up to a year with proper care. They require cleaning and storage in a specialized solution to maintain their quality.
   

5. Visual Clarity

• Regular Contact Lenses: Effective for most users, but may not provide optimal clarity for those with irregular corneas or advanced astigmatism.

• Scleral Lenses: Their custom design ensures a perfect fit, delivering sharper vision for individuals whose conditions make standard lenses insufficient.
   

Who Can Benefit From Scleral Lenses?

Scleral lenses are a game-changer for people with:
 

• Keratoconus or corneal ectasia

• Severe dry eye disease

• Post-surgical complications from LASIK or corneal transplants

• High levels of astigmatism or irregular corneal shapes

• Sensitivities that make soft lenses uncomfortable
