If you wear scleral contact lenses, you might be wondering how long your lenses will last before they need to be replaced.
Scleral contact lenses are a durable and long-lasting option for managing various eye conditions, including severe dry eye disease. However, they’re not indestructible. On average, scleral lenses can last about 1—2 years with proper care, but their lifespan depends on factors like:
- Regular maintenance
- How often they’re worn
- The health of your eyes
What Are Scleral Contacts?
Scleral contact lenses are a specialized type of lens designed to cover not just the cornea but also part of the sclera (the white portion of the eye). Unlike traditional soft contact lenses, scleral lenses rest on the sclera and vault over the cornea.
This unique design makes them particularly helpful for those a variety of contact lens wearers:
- People with irregular corneas due to conditions like keratoconus, corneal scarring, or post-surgical complications.
- Those who are looking to manage severe dry eye syndrome, especially in cases related to Sjögren’s syndrome or other autoimmune disorders.
- Individuals with high astigmatism or those who struggle to achieve clear vision with traditional lenses.
Scleral lenses are made from rigid, gas-permeable material, which allows oxygen to reach the eye, promoting better eye health. This sturdy construction also makes them more durable than soft lenses, though it doesn’t mean that they’ll last forever.
What Affects the Durability of Scleral Lenses?
The lifespan of scleral lenses can vary widely. Here are some key elements that impact their longevity:
1. Material Quality
Scleral lenses are made from rigid, gas-permeable materials. The quality of this material significantly influences how long the contacts can endure daily wear. Higher-quality lenses tend to resist deposits and scratches better, contributing to a longer lifespan.
2. Frequency of Use
How often scleral lenses are worn also plays a major role. Daily wearers may need more frequent replacements due to natural wear and tear.
3. Environmental Exposure
The environment you expose your lenses to can affect their lifespan. Dust, debris, and certain chemicals can cause damage or accelerate deterioration of the surface of the lens. For example, exposure to makeup or harsh cleaning solutions may reduce durability over time.
4. Cleaning & Maintenance Practices
Improper cleaning and storage of scleral lenses can lead to buildup, warping, or even damage. Using the wrong solutions or skipping daily cleaning entirely can shorten the lifespan of your lenses significantly.
Proper Care to Extend the Life of Your Scleral Contacts
To ensure you get the longest lifespan from your lenses, cleaning and proper care are important. Here’s how to keep them in tip-top shape:
1. Clean Your Lenses Daily
Use a solution specifically formulated for rigid gas-permeable lenses. Avoid generic or multipurpose solutions unless they’re approved for use with scleral lenses. This will prevent deposits from building up on the surface.
2. Rinse and Refill with Fresh Solution
Never reuse the saline solution in your lens case. Always discard the old solution and replace it with fresh saline to avoid contamination and bacterial build-up.
3. Store in a Clean, Hygienic Case
Be sure your lens case is free of debris and stored in a sanitary environment. Clean your case at least once a week with approved solutions, replacing it every 2—3 months.
4. Handle Lenses with Clean Hands
Wash your hands thoroughly with soap and water before touching your lenses. Avoid any hand creams or lotions that could transfer to the lenses.
5. Regular Professional Cleanings
Even with diligent care, some buildup or protein deposits are unavoidable over time. Consult an eye care professional periodically for deep cleaning services.
Signs It’s Time to Replace Your Scleral Lenses
Even with excellent maintenance, no contact lens is designed to last forever. Recognizing the signs of wear or damage is essential for both comfort and eye health. Below are some common indicators that your scleral lenses may need to be replaced:
- Scratches or Chips: Small scratches can interfere with vision and make the lens uncomfortable to wear.
- Persistent Haze: A cloudy or hazy appearance that doesn’t go away after cleaning may indicate a buildup of deposits that can’t be removed.
- Warpage: Over time, lenses can lose their shape, which can cause discomfort or impact visual clarity.
- Discomfort: If lenses suddenly feel less comfortable, or if irritation becomes frequent, it may be a sign they’re no longer fitting correctly.
- Reduced Vision Quality: A decrease in visual clarity that persists even after cleaning the lenses is a red flag that replacement might be necessary.
Keeping Your Vision Clear & Comfortable
When properly cared for, scleral contacts can last 1—2 years or even longer. Their durability, comfort, and visual benefits make them a fantastic option for those with specialized eye needs.
By following a thorough cleaning routine, being mindful of environmental exposures, and consulting your eye care professional as needed, you can make the most of your investment.
Staying observant of your lenses and replacing them at the appropriate time will contribute not only to clear vision but also to long-term eye health.If it’s time to replace your lenses, or you have any questions about scleral lenses and your eye health in general, reach out to Littlefield Eye Associates to book an appointment.
