Custom Soft Contact Lenses for Keratoconus
Understanding Keratoconus
Keratoconus is a progressive condition where the cornea, the clear front part of the eye, becomes thin and irregular over time. Early detection and proper care can help manage it effectively and protect long-term eye health.
Keratoconus often starts in the teen years or early adulthood and may run in families. It can be linked to frequent or forceful eye rubbing, allergies, or certain health conditions like Down syndrome, connective tissue disorders, and asthma. While the exact cause is not always clear, avoiding eye rubbing and protecting your eyes from irritants may help slow its progression.
Early signs include blurry vision, sensitivity to light, frequent prescription changes, and trouble seeing at night. As it advances, you might notice double vision, halos around lights, ghost images, or eye redness due to irritation. Regular eye exams are key to catching these changes early and finding the right vision correction options before the condition worsens.
The cone-shaped cornea distorts how light enters the eye, causing irregular astigmatism. This makes it hard for glasses to fully correct vision in moderate to advanced cases. Recent research suggests that keratoconus affects about 1 in 1,000 to 1 in 2,000 people worldwide, but treatments like custom lenses can make a big difference in preserving vision and daily comfort.
Keratoconus progresses through mild, moderate, and advanced stages. In mild stages, vision can often be corrected with glasses or standard contacts. Moderate and advanced stages typically require specialized lenses or surgical interventions, making timely diagnosis crucial for improving long-term outcomes.
In addition to custom soft lenses, your eye doctor might discuss other ways to manage keratoconus and preserve your vision.
- Corneal cross-linking to strengthen and stabilize the cornea
- Intacs, which are corneal ring segments, to reshape the cornea mechanically
- Scleral and rigid gas-permeable lenses for advanced correction
- Corneal transplant surgery in rare, severe cases
What Are Custom Soft Contact Lenses?
Custom soft contact lenses are flexible lenses designed specifically for the irregular cornea caused by keratoconus. Unlike standard lenses, they provide a tailored fit that helps improve vision clarity while maintaining comfort for long hours of daily wear.
Regular soft contacts are mass-produced for common vision issues, but they often slip, rotate, or blur on a keratoconus cornea. Custom versions are designed using detailed corneal measurements, creating lenses that provide stability and sharper focus. This personalization also helps reduce irritation and improves wear time compared to off-the-shelf lenses.
These lenses come in various designs to suit different needs. Some are made with high water content for all-day comfort, while others use specialized materials to correct higher levels of astigmatism. Brands like Bausch + Lomb and CooperVision offer custom options that our eye doctors can adjust for the best results.
Patients with mild to moderate keratoconus often find these lenses helpful, especially if rigid gas-permeable contacts feel too uncomfortable or are difficult to tolerate. They are suitable for those with an active lifestyle or for patients sensitive to harder lens materials. Custom soft lenses may also be an option for patients who experience intolerance to hybrid or scleral lenses.
Most custom soft lenses are made from silicone hydrogel or high-water-content hydrogel. Silicone hydrogel offers superior oxygen permeability to maintain corneal health, while high-water-content hydrogels provide extra flexibility and moisture. Your eye doctor will select the best material based on your specific corneal shape and tear film characteristics.
Benefits of Custom Soft Lenses
These lenses provide several advantages, from greater comfort to improved vision quality. They can enhance your quality of life by making everyday tasks easier and more enjoyable.
Unlike rigid lenses that may feel scratchy or cause irritation, custom soft lenses mold gently to the eye's surface. This reduces dryness, irritation, and the feeling of a foreign body in the eye, allowing for longer wear times. Many patients report that they barely notice the lenses after a short adjustment period.
By conforming to the irregular cornea, these lenses help focus light more evenly onto the retina. This leads to sharper images and less distortion during daily activities like driving or reading. Studies show that a majority of keratoconus patients achieve good functional vision with well-fitted custom soft options.
Soft lenses are relatively simple to insert and remove, making them user-friendly for beginners and those switching from other lens types. They also work well in combination with lubricating drops for added comfort. With proper care, they can become a seamless part of your daily routine.
For sports or outdoor activities, these lenses tend to stay in place better than glasses and reduce issues related to fogging or displacement. Some custom soft lenses come with UV protection, helping shield your eyes from potential sun damage, though sunglasses are still recommended for full protection.
Improved vision and comfort can boost confidence, independence, and overall quality of life. This helps reduce the frustration often experienced with the vision challenges of keratoconus, allowing you to participate more fully in social and professional activities.
The Fitting Process
Getting fitted for custom soft lenses involves a detailed evaluation to ensure the best match for your eyes. This step-by-step customization helps create lenses that feel right and provide reliable vision correction.
Our eye doctors will measure the shape and curvature of your cornea using advanced diagnostic tools such as corneal topography or tomography. This creates a precise 3D map of your eye to guide lens design. It is a quick, painless test that provides essential information for a perfect fit.
You will try on trial lenses to test comfort and vision clarity. Your feedback from these trials allows for fine-tuning the design, such as adjusting the thickness, diameter, or curvature. Most patients need one or two follow-up visits to finalize the ideal lens design that optimizes fit and visual results.
Our specialists provide training on how to insert, remove, and care for your lenses properly. This education is important to maximize lens life, maintain eye health, and enhance your overall experience with your new custom soft lenses.
After receiving your lenses, regular check-ups ensure they continue to perform well as your eyes change. These visits help detect early issues, monitor keratoconus progression, and confirm that the fit and vision correction remain effective over time.
Care and Maintenance Tips
Proper care keeps your custom soft lenses clean and safe, extending their life and protecting your eyes. Following a simple routine can prevent infections and ensure all-day comfort.
Always wash and dry your hands before handling lenses. Use a multipurpose solution like Biotrue or Opti-Free to clean, rinse, and store them overnight. Gently rubbing the lenses with the solution removes buildup and keeps them clear of protein deposits.
Store your lenses in a clean case filled with fresh solution each night. Replace the case every three months to reduce the risk of bacterial contamination. It is also critical to follow the recommended replacement schedule for your lenses, which is often monthly.
Never wear lenses while swimming or sleeping unless specifically advised by your doctor, as this increases the risk of infection. If your eyes feel dry, preservative-free artificial tears such as Refresh Tears can provide relief. Promptly report persistent discomfort, redness, or vision changes to your doctor.
Be alert for symptoms such as pain, excessive redness, unusual discharge, or sudden changes in vision. These may indicate an infection or improper lens fit and require immediate professional attention to protect your eye health.
Potential Challenges and Solutions
While custom soft lenses work well for many patients, some challenges may arise. Knowing what to expect can help you adjust smoothly and get the most from your lenses.
Dry eyes are common with keratoconus, and lenses can sometimes exacerbate the sensation. Using preservative-free moisturizing drops throughout the day can help maintain comfort. If discomfort continues, your eye doctor may adjust the lens material or recommend alternative options such as hybrid or scleral lenses.
In more advanced cases, custom soft lenses alone might not provide sufficient correction. Your doctor might recommend other treatments such as corneal cross-linking or suggest scleral lenses, which are larger rigid lenses that vault over the cornea entirely. Often, a combination of treatments provides the best results.
Some patients may experience a brief adjustment period when first wearing custom soft lenses. Following your eye doctor’s guidance on wear time and attending all scheduled follow-ups helps ease this transition and maximize your long-term comfort and vision.
If your vision worsens, your lenses feel consistently uncomfortable, or you notice new symptoms, schedule a check-up right away. Redness, pain, or unusual discharge could be signs of an infection or improper fit. Early attention prevents complications and protects your long-term vision.
