Understanding Scleral Lenses
Dealing with vision problems can significantly impact everyday tasks like reading, driving, or working. While glasses and standard contact lenses offer relief for many, they aren't the perfect solution for everyone. That's where scleral lenses come into play, offering a breakthrough for those who struggle with traditional vision correction methods.
At Nationwide Vision, we understand that everyone's vision needs are unique. For some, glasses are too cumbersome, and regular contacts might not fit comfortably due to unique corneal shapes. That’s why we're excited to discuss scleral lenses, which have been changing lives by providing a comfortable, clear vision solution for those hard-to-fit eyes.
Understanding Your Contact Lens Options
To appreciate the unique benefits of scleral lenses, it's helpful to compare them with traditional types of contact lenses.
Soft Contact Lenses
Soft contact lenses are the most commonly used type. They are made from a soft, flexible silicone that conforms closely to the cornea. These lenses are typically less expensive and are available in daily, weekly, or monthly disposables. While they are convenient and initially comfortable, their snug fit can reduce oxygen flow to the cornea, potentially causing dry eyes and discomfort over time. They also may not provide as sharp of vision correction as other options as they are mass-produced.
Rigid Gas Permeable Lenses
Rigid Gas Permeable (RGP) lenses are more durable and breathable than soft lenses. Made from a firmer material, they sit on the cornea, allowing for better oxygenation, which can lead to improved comfort and eye health. RGPs offer clearer vision and can be more cost-effective in the long run as they last longer. However, their less conforming fit means they can dislodge more easily, and they require a period of adaptation for new wearers. Additionally, they are more expensive upfront.
How Scleral Lenses Enhance Vision and Comfort
Scleral lenses are specialized RGP lenses designed to vault over the entire corneal surface and rest on the white part of the eye, the sclera. This design avoids direct contact with the sensitive cornea, which is particularly beneficial for those with irregular corneas or conditions that make wearing standard contacts difficult.
These lenses are custom-fitted to each wearer's specific eye shape, providing a tailored solution that helps achieve optimal vision without discomfort. The larger diameter and unique positioning of scleral lenses make them stable, less likely to dislodge, and excellent for providing clear, uninterrupted vision.
The Many Benefits of Scleral Lenses
Scleral lenses offer numerous advantages over traditional contact lenses:
Comfort: Their unique design distributes pressure evenly across the eye, avoiding the cornea and reducing irritation.
Hydration: They maintain a reservoir of saline solution beneath the lens, which keeps the eye moist and comfortable, especially beneficial for those with dry eye syndrome.
Vision Quality: Scleral lenses provide sharp, clear vision by correcting vision uniformly across the lens surface.
Durability: Designed for long-term use, scleral lenses are durable and can last a few years with proper care.
Considerations and Care for Scleral Lenses
Despite their many benefits, scleral lenses have some considerations. They are typically more expensive than other types of lenses due to the custom fitting and manufacturing process (sometimes as much as five times more than what traditional contacts cost). They also require diligent maintenance to prevent debris buildup under the lens, which can affect vision clarity. In fact, some users may find they need to remove and clean their lenses multiple times a day. Initially, some users may find the size and sensation of scleral lenses to be unusual. However, most adapt quickly and enjoy the enhanced comfort and vision benefits.
Are Scleral Lenses Right for You?
Scleral lenses are particularly suited for individuals with specific eye conditions that affect the corneal surface, including:
Astigmatism
Keratoconus
Stevens-Johnson Syndrome
Sjogren’s Syndrome
They are also ideal for patients recovering from eye surgeries who require gentle, effective vision correction.
