What are scleral lenses?

 

Scleral lenses are contact lenses that rest directly on the sclera (the white part of the eye), covering the cornea without touching it, unlike other types of contact lenses.

They are primarily recommended for keratoconus, corneal transplants, intracorneal rings, and dry eye, although they can be fitted for almost any eye.

 

The main advantages of these lenses are:

  • Comfort and stability
  • Significant visual improvement
  • Protection against wind and dry eye

 Types of scleral lenses

We work with many contact lens brands that manufacture a wide range of scleral lenses, and it is possible that any of them could work for your specific case.

Which one is the right choice? How do you select the best option?

It depends largely on:

  • The condition of the eyes.
  • The patient's goals: What does the patient want to do with them? Example: Material recommendations differ depending on whether the patient wants to use them to view a computer clearly all day or simply to play soccer.
  • The amount the patient wishes to invest in the lenses.

A key aspect of any scleral lens fitting is understanding the advantages and limitations of the specific type of scleral lens selected. For example, some lenses may significantly improve vision but cause eye redness and/or fog up easily.

 

This is a summary of the types of scleral lenses that can be fitted.

 

Standard scleral lens

  • A basic scleral lens that works well for healthy corneas and mild-to-moderate keratoconus. It is not recommended for large corneas or eyes with significant scleral irregularities (such as pingueculae or pterygia), as it may cause persistent redness or fail to provide optimal vision.

  • It cannot be used for advanced keratoconus because its size is insufficient to fully cover the cornea.
  • It is prone to drying out or becoming cloudy.

 

Advanced standard scleral lens

  • A more customizable design that performs better on large corneas or eyes; ideal for keratoconus of almost any severity, as well as for eyes with intracorneal rings or corneal transplants.
  • It does not perform well in cases with scleral irregularities (such as pingueculae or pterygia), as it may cause significant redness in certain areas of the eye.
  • It is prone to drying out or becoming cloudy.

 

Specialized scleral lens for dry eye

  • A design that improves visual quality in cases of residual astigmatism caused by lens flexure.
  • The material features a special coating that prevents hazy vision, making it ideal for those who spend long hours working at a computer.

Specialized "Elite" scleral lens

  • The lens edge is adjusted using a system of elevations and depressions, allowing it to better match the scleral anatomy; this results in a gentler, more comfortable fit for extended wear. This design is highly recommended for cases with small to moderate scleral growths (pingueculae or pterygia), as it avoids compressing them, thereby preventing eye redness.
  • It features surface treatments to prevent hazy vision.

 

3D-scanned scleral lens

  • A "free-form" scleral lens representing the pinnacle of scleral lens technology. The eye's surface—including both the cornea and the sclera—is scanned, and a lens is designed to perfectly match the eye's shape with micron-level precision. It is the best option for corneal or scleral irregularities of any size and offers superior comfort. 
  • It features surface treatments to prevent hazy vision.

 

Ultra-high-definition 3D-scanned scleral lens

  • It shares the same characteristics as the free-form design, with the difference that the prescription can be applied using aberrometry guidance, thereby achieving the best possible visual quality. This is the most advanced scleral lens in the world.
  • It features surface treatments to prevent hazy vision.

How do we fit the lenses?

During the consultation, a comprehensive eye assessment is performed—including topography and tear quality evaluation—to provide a detailed explanation of what wearing the lenses will be like.

The lens fitting process incorporates scleral topography; this is the world's most advanced technology for fitting scleral lenses. It involves a complete scan of the eye's surface, enabling the analysis and fabrication of contact lenses with the highest possible precision.

Problems with scleral lenses?

The best way to evaluate issues with scleral lenses is to come in for a consultation. Some of the most frequent complications include red eyes, hazy vision, or blurred vision.

 

Scleral irregularities (Fleshy growths)

These are known as pingueculae—bumps on the conjunctiva (often colloquially referred to as "fleshy growths") that vary in size and shape. If they aren't accounted for during the scleral lens fitting process, they can cause red eyes, conjunctival prolapse, discomfort, and blurred vision. Depending on their size, problems can be avoided by selecting the appropriate lens design and/or features.

Hazy vision

Tears must keep the surface of any contact lens lubricated. With scleral lenses that lack surface treatments, it is common for the surface to dry out and cause hazy vision after a few hours of wear (depending on the individual case)—especially in dry climates or high-altitude locations like Mexico City.
