Are Scleral Lenses Safe for Long-Term Use?

Scleral lenses have become a trusted solution for individuals with complex vision issues, such as keratoconus, severe dry eye, and irregular corneas. Known for their larger size and ability to vault over the cornea, these lenses offer improved comfort and visual clarity where traditional contact lenses may fall short. But an important question often arises: Are scleral lenses safe for long-term use?
 

What Are Scleral Lenses?

Scleral lenses are gas-permeable lenses that rest on the sclera (the white part of the eye) and create a fluid-filled reservoir over the cornea. This design offers both vision correction and therapeutic benefits by keeping the cornea moist throughout the day.
 

Long-Term Safety of Scleral Lenses

When properly prescribed, fitted, and cared for, scleral lenses are safe for long-term use. Here are a few key factors that contribute to their safety:
 

• High Oxygen Permeability: Modern scleral lenses are made from materials that allow oxygen to pass through to the cornea, which is critical for maintaining corneal health. While the lenses cover more of the eye than standard contacts, advances in lens materials have significantly reduced the risk of oxygen deprivation.

• Custom Fit for Long-Term Comfort: Because scleral lenses are custom-designed for each patient, they distribute pressure evenly across the eye and avoid direct contact with the sensitive cornea. This makes them more comfortable and reduces the likelihood of long-term complications, especially when worn as directed.

• Protection for Compromised Eyes: For patients with ocular surface diseases or severe dry eye, scleral lenses can serve a protective role by keeping the eye hydrated and shielding it from environmental irritants. This therapeutic effect can actually improve eye health over time.
   

Routine Monitoring Is Key

Like any medical device, long-term safety depends on regular checkups with your optometrist. Eye health can change, and your eye doctor can detect early signs of complications such as corneal hypoxia, lens fit issues, or deposits that could impact vision and comfort.
 

Tips for Safe Long-Term Wear

• Follow your eye doctor’s wear and care instructions carefully.

• Schedule routine eye exams to monitor corneal health.

• Clean and disinfect your lenses daily with recommended solutions.

• Report any discomfort, redness, or changes in vision promptly.
