How to Properly Insert, Remove, and Care for Your Scleral Lenses

Introduction

For individuals who require specialized vision correction, scleral lenses provide unparalleled comfort and clarity. These large-diameter gas-permeable lenses offer a stable fit and an essential moisture reservoir, making them an excellent option for those with conditions such as keratoconus, severe dry eye syndrome, or corneal irregularities. However, because they differ from traditional contact lenses, proper handling and care are crucial for maximizing their effectiveness and ensuring eye health. This guide will walk you through the correct techniques for inserting, removing, and maintaining your scleral lenses to ensure long-lasting comfort and performance.

How to Properly Insert Scleral Lenses

Since scleral lenses are larger than traditional contacts and rest on the sclera rather than the cornea, inserting them requires a specific method. Here’s a step-by-step guide:

Step 1: Wash Your Hands

Before handling your lenses, thoroughly wash your hands with a mild, fragrance-free soap. Dry them with a lint-free towel to avoid debris sticking to the lenses.

Step 2: Prepare the Lens

• Place the lens in the palm of your hand.
• Rinse it with a preservative-free saline solution to remove any debris.
• Inspect the lens for cracks, chips, or buildup before insertion.

Step 3: Fill the Lens with Solution

Scleral lenses create a tear reservoir between the lens and the cornea, so they must be filled with a sterile, preservative-free saline solution before insertion. This prevents air bubbles and ensures hydration throughout the day.

Step 4: Position the Lens

• Use a lens inserter (plunger) or the three-finger tripod method to hold the lens.
• Lean forward and keep your face parallel to the surface below to minimize the risk of bubbles forming.
• Use your other hand to hold your eyelids wide open.

Step 5: Insert the Lens

• Carefully place the lens directly onto the sclera while looking straight ahead.
• Blink gently to allow the lens to settle into place.
• Check for air bubbles. If you notice bubbles, remove and reinsert the lens.

How to Remove Scleral Lenses

Removing scleral lenses correctly prevents damage to your eyes and the lenses themselves. Follow these steps to safely remove them:

Step 1: Wash and Dry Your Hands

As with insertion, start by washing your hands with mild soap and drying them thoroughly.

Step 2: Use a Suction Plunger or Finger Method

There are two common ways to remove scleral lenses:

1. Using a Suction Plunger:
   
   • Moisten the tip of a small suction plunger.
   • Gently place the plunger on the lower third of the lens.
   • Apply slight pressure to break the seal and lift the lens away.
   • Once removed, slide the lens off the plunger using your other hand.
2. Using the Finger Method:
   
   • Look up and pull down your lower eyelid.
   • Use your fingertip to gently press the lower edge of the lens.
   • Break the suction and slide the lens downward before removing it.

Cleaning and Maintaining Your Scleral Lenses

Proper care extends the lifespan of your scleral lenses and ensures eye safety. Follow these guidelines for daily maintenance:

Daily Cleaning Routine

• Rinse and Rub: After removal, place the lens in your palm, apply a few drops of a recommended cleaning solution, and gently rub both sides.
• Rinse Thoroughly: Use a preservative-free saline solution to rinse off any debris.
• Disinfect: Store lenses in a clean case filled with a prescribed disinfecting solution overnight.

Weekly Deep Cleaning

• Use a specialized enzymatic cleaner once a week to remove protein and lipid buildup.
• Avoid using tap water, as it can introduce bacteria and contaminants.

Storing Your Lenses

• Always store lenses in a clean, dry case with fresh solution.
• Replace the storage case every three months to prevent bacterial growth.
• Keep your lenses away from direct sunlight and extreme temperatures.

Troubleshooting Common Issues

Even with proper care, some users may experience challenges with their scleral lenses. Here are common problems and solutions:

Air Bubbles Under the Lens

• Bubbles can cause discomfort and blurry vision. If this happens, remove and reinsert the lens, ensuring it is completely filled with saline before insertion.

Lens Discomfort

• If you experience discomfort, check for debris, scratches, or improper fit. Consult your eye care provider for adjustments if necessary.

Fogging

• Lens fogging can be due to tear film instability. Using anti-fogging drops or adjusting the cleaning routine may help reduce this issue.

Tips for Long-Term Success with Scleral Lenses

• Follow a Routine: Establishing a consistent insertion, removal, and cleaning routine helps ensure lens hygiene and comfort.
• Regular Eye Exams: Schedule routine check-ups to ensure the lenses fit properly and address any vision changes.
• Carry Backup Supplies: Always have a backup saline solution, lens case, and plunger for emergencies.
• Monitor Eye Health: If you experience redness, irritation, or vision changes, consult your eye doctor immediately.

Conclusion

Caring for scleral lenses properly is essential to maximizing their benefits and ensuring long-term eye health. By following the correct insertion and removal techniques, maintaining a diligent cleaning routine, and addressing common issues proactively, you can enjoy clear vision and comfort throughout the day. With regular care and attention, scleral lenses can be a reliable and effective solution for those requiring advanced vision correction.
