When it comes to correcting your vision, scleral lenses are a remarkable option that many people may not be familiar with. These specialized contact lenses are larger in diameter than traditional lenses, resting on the sclera (the white part of your eye) and creating a smooth optical surface over the cornea.
Whether you’ve recently made the switch to scleral lenses or are simply exploring your options, knowing how to insert them is crucial as they have a slightly different technique than traditional lenses. Inserting scleral lenses requires holding your eyelids open and placing the saline-filled lens against your eyeball. Once you feel the solution, you can press the lens onto the eye. It might feel tricky at first, but with some practice, it becomes second nature.
What Are Scleral Lenses?
Scleral lenses are a type of contact lens that rests on the sclera, the white part of your eye, and vaults over the cornea without touching it. This design creates a tear-filled reservoir between the lens and the cornea, providing several unique benefits, such as:
- Enhanced Comfort: The fluid reservoir minimizes irritation for sensitive eyes.
- Improved Stability: Their larger size makes them more stable on the eye, reducing the chance of dislocation.
- Better Oxygen Permeability: Advanced materials allow for better oxygen flow, promoting corneal health.
Who Can Benefit from Scleral Lenses?
Scleral lenses aren’t simply bigger for the sake of it. Their increased size makes them particularly beneficial for people with eye conditions that many normally preclude them from enjoying contact lenses’ benefits.
Some conditions scleral lenses can address include:
- Keratoconus: These lenses can allow people with this progressive eye disease to still see clearly by providing a smooth optical surface.
- Dry Eye Syndrome: The tear reservoir offers continuous moisture all day, alleviating dryness.
- Post-Surgical Eyes: Ideal for eyes that have undergone procedures like LASIK, RK (Radial Keratotomy), or corneal transplants.
An optometrist may even prescribe scleral lenses for the few people who simply can’t tolerate regular contact lenses and want more comfortable wear.
The Insertion Process
Inserting scleral lenses may seem daunting at first, but follow these steps, and you’ll become a pro in no time:
- Wash Your Hands: Clean hands are crucial to prevent infections, so make sure to wash them thoroughly with soap and water, then dry them with a lint-free towel.
- Hold the Lens: Depending on your preference, you can either use the tripod method (balanced on the tips of three fingers), the 2-finger method (placed on the pads of your index and middle finger, or use a special applicator.
- Fill the Lens with Saline Solution: This step is essential as the saline solution creates the necessary tear reservoir to keep your eyes hydrated.
- Position Yourself: Lean over so you’re facing the floor or another surface to prevent the solution from spilling out of the lens.
- Place the Lens: Hold your eyelids open wide using your fingers. You’ll need to open them wider than the lens. Carefully bring the lens closer to the eye until you can feel the solution.
- Release and Blink: Once the lens is in place, gently close your eyes and give a few blinks to help it stay secure and comfortable.
Some people prefer to use a scleral application stand that will hold the lens for you so you can use both hands to open your eyelids. Some even come with a fixation light, a gentle light that helps reduce the reflex to look away—which can cause you to apply the lens off-center.
Tips for a Comfortable & Successful Insertion
- Use a Mirror: You can place a mirror on a table and lean over it. This can be especially helpful for beginners.
- Stay Calm: Anxiety can make insertion harder; take deep breaths and move at your own pace.
- Practice Makes Perfect: The more you do it, the easier it gets.
Maintaining Scleral Lenses
Proper maintenance not only helps your lenses last, but it also protects your eye health:
- Daily Cleaning: Use a recommended lens cleaner to remove debris and protein buildup. Gently rub the lenses with clean fingers to ensure thorough cleaning.
- Rinse with Saline Solution Before Insertion: Never use tap water, as it can contain harmful microorganisms that may cause infections. Instead, use sterile saline solution to rinse away any remaining cleaner.
- Store in a Clean Case: Always use a fresh, sterile lens case and replace the solution daily to prevent contamination. Make sure to let the case air dry when not in use and replace it every 3 months.
Potential Challenges & How to Overcome Them
While scleral lenses offer a myriad of benefits, they can come with certain challenges, especially for first-time users. Recognizing these difficulties and learning how to manage them can make the adjustment period smoother.
Some users might experience slight discomfort initially as their eyes adapt to the lenses. This is normal and usually subsides within a few days. Here’s our tip: gradually increase wearing time. Start with a couple of hours a day if you need to and build up slowly.
Occasionally, air bubbles can get trapped under the lens. This can be uncomfortable and cause vision disturbances. Ensure the lens is completely filled with saline solution before insertion and stare straight ahead as you put the lens in.
