How Are Scleral Lenses Different from Regular Contacts?

Contact lenses have come a long way over the years, with advancements offering solutions for a wide range of vision needs. While many people are familiar with standard soft contact lenses, scleral lenses provide a unique alternative. Understanding how they differ can help you determine which option might be right for you.

Understanding Regular Contact Lenses?

Regular contact lenses, such as soft or rigid gas-permeable (RGP) lenses, rest directly on the cornea - the clear, dome-shaped surface at the front of your eye. They correct common vision issues like nearsightedness, farsightedness, and astigmatism, and are available in daily, biweekly, and monthly replacement schedules.

Soft contact lenses are the most common, offering comfort and ease of use, while RGP lenses provide sharper vision for some prescriptions. However, both types rely on the cornea for their fit and stability.

What Are Scleral Lenses?

Scleral lenses are larger in diameter than regular contacts and are designed to vault over the cornea entirely, resting on the sclera (the white part of your eye). This creates a space between the back of the lens and the cornea, which is filled with a sterile saline solution before insertion. This liquid cushion provides constant hydration and helps protect sensitive or irregular corneal surfaces.

Who Might Benefit from Scleral Lenses?

Scleral lenses can be an excellent choice for individuals with:

• Keratoconus or other corneal irregularities

• Severe dry eye disease

• Corneal scarring or injury

• Post-LASIK or other refractive surgery complications

• Difficulty achieving clear vision with regular contacts or glasses

The Importance of Contact Lens Exam and Fitting

A contact lens exam and fitting is essential to ensure your lenses provide both clear vision and long-term eye health. Unlike a standard eye exam, this specialized appointment evaluates the unique shape, size, and health of your eyes to determine the most suitable lens type and prescription. Your optometrist will measure your corneal curvature, assess tear film quality, and check for any conditions that may affect lens comfort or safety. Your doctor will recommend the best type of contact lens for your needs, ensuring they match your lifestyle, prescription, and eye health. 

A proper fitting helps prevent complications like irritation, dryness, or infection, while also ensuring your lenses stay comfortable throughout the day. By taking the time for a professional exam and fitting, you protect your eyes and set yourself up for the best possible contact lens experience.
