Custom Scleral Lens Designs: How Modern Labs Create Perfect Fits

Scleral lenses have transformed the way complex vision problems are managed. For patients with irregular corneas, dry eye disease, or post-surgical complications, standard lenses often fail to provide clarity or comfort.


Thanks to advancements in diagnostic imaging and manufacturing, modern scleral lens designs now offer highly precise, personalized solutions.


At the Charlotte Contact Lens Institute, we work closely with advanced optical labs to deliver lenses that match each patient’s unique eye shape and visual needs.

  • What Makes Scleral Lenses Different?

Unlike traditional contact lenses, scleral lenses rest on the sclera (the white part of the eye) and vault completely over the cornea. This design:

 

  • Neutralizes corneal irregularities
  • Creates a smooth optical surface
  • Holds a fluid reservoir that enhances comfort
  • Improves vision stability throughout the day

 

Because of these benefits, scleral lenses are often the preferred choice for complex corneal conditions.

  • The Role of Advanced Eye Measurements

Creating a perfect scleral lens fit begins with highly detailed diagnostics. Modern clinics use tools such as:

 

  • Corneal topography
  • Scleral profilometry
  • Wavefront aberrometry
  • Anterior segment imaging

 

These measurements capture both corneal shape and scleral contour, ensuring the lens aligns properly without excessive pressure or movement.

  • How Modern Labs Design Custom Scleral Lenses

Once diagnostic data is collected, it is sent to specialized laboratories where advanced software and precision manufacturing take over.

  • Digital Lens Design
Labs use 3D modeling to design lenses that match the eye’s exact contours, allowing for micron-level accuracy.
  • Precision Manufacturing
Computer-controlled lathes carve lenses from high-quality materials, ensuring consistency, oxygen permeability, and durability.
  • Customization Beyond Shape

Labs can adjust:

 

  • Lens diameter
  • Vault height
  • Edge alignment
  • Optical zones

 

This level of detail is essential for patients seeking custom contact lenses charlotte NC that provide both clarity and long-term comfort.

  • Why Customization Matters for Vision and Comfort

A well-designed scleral lens does more than correct vision—it improves quality of life. Proper customization helps:

 

  • Reduce glare and halos
  • Improve contrast sensitivity
  • Minimize dryness and irritation
  • Support long wearing times

 

For patients who struggled with previous lenses, custom scleral designs often become a life-changing solution.

  • Who Benefits Most from Custom Scleral Lenses?

Custom scleral lenses are commonly recommended for patients with:

  • Keratoconus or corneal ectasia
  • Post-LASIK or post-surgical irregularities
  • Severe dry eye disease
  • Corneal scarring or trauma
  • Poor tolerance to standard contacts

A comprehensive evaluation determines whether scleral lenses are the right option for each individual.

  • Why Choose the Charlotte Contact Lens Institute

Our practice focuses exclusively on specialty contact lenses and complex cases. By combining advanced diagnostics with trusted laboratory partnerships, we deliver personalized lens solutions designed for optimal vision and comfort.

  • Frequently Asked Questions
What are custom scleral lenses?
Custom scleral lenses are large-diameter contact lenses designed specifically for an individual eye. They vault over the cornea and rest on the sclera, creating a smooth optical surface for clearer, more stable vision.
Modern labs use advanced digital modeling, 3D design software, and precision manufacturing tools to shape lenses that match the eye’s unique contours with exceptional accuracy.
Yes. When properly fitted, scleral lenses are typically very comfortable because they do not touch the sensitive cornea and maintain a fluid layer that keeps the eye hydrated.
Patients with keratoconus, corneal ectasia, post-surgical irregularities, severe dry eye, or difficulty wearing standard contacts often benefit the most from custom scleral lenses.
After the initial evaluation and measurements, lenses are usually designed and manufactured within a few weeks. Follow-up visits help fine-tune the fit if needed.
Yes. Proper cleaning, storage, and handling are essential for comfort and eye health. Your eye care provider will provide detailed care instructions during the fitting process.
