How Hard Is Learning to Insert Scleral Lenses?

If you have been prescribed scleral lenses to treat keratoconus or another severe corneal condition, it is completely normal to feel a bit anxious about the insertion process. The lenses are larger than traditional contacts, and the idea of bringing them toward your eye can feel intimidating.

The good news is that the learning curve is much shorter than most people think. While the process requires a bit of patience and technique, the rewards are life-altering. Understanding exactly what to expect can help you overcome your initial hesitation and fast-track your success.

The 15-Minute Breakthrough

Many new patients come into the practice expecting that it will take weeks of frustrating practice at home before they can smoothly insert their lenses. In reality, the vast majority of patients get it right within just 10 to 15 minutes of hands-on practice.

The process is highly streamlined by using dedicated tools. Rather than juggling multiple gadgets, you only need two DMV plungers (or “suckers”):

 

• • One plunger dedicated exclusively to scleral lens insertion.

• • A separate plunger dedicated exclusively to lens removal.

Once you understand the basic mechanics and learn how to coordinate your hands, the process quickly becomes second nature.

The Secret to a Perfect Insertion: Mechanics Over Movement

The single most common mistake new patients make comes down to how they position their heads. Scleral lenses must be completely filled with saline fluid prior to insertion. Because the lens holds liquid, it has to move in a purely vertical direction to prevent the fluid from spilling out or creating trapped air bubbles.

When instructed to look down at the lens, many patients naturally keep their chins up and simply rotate their eyes downward. This tilt causes the saline to spill, resulting in a failed attempt.

To overcome this, use the “chin-tuck” technique:

 

• • Tuck your chin deeply into your chest.

• • Keep your eyes in a completely neutral position, facing straight ahead relative to your face.

• • Bring the fluid-filled lens straight up in a perfectly vertical line to meet the eye.

By moving your entire head rather than just your eyes, you keep the lens perfectly level and secure the liquid place.

Overcoming the Fear: Painless and Unnoticed

It is important to recognise that any fear or anxiety you feel about putting the lens in your eye is not founded in actual risk. Scleral lenses are entirely painless. In fact, because of how they rest on the sclera (the white part of the eye) and vault completely over the sensitive cornea, they generally cannot be felt at all once they are in place.

For patients dealing with the poor vision caused by keratoconus, motivation is usually incredibly high. Overcoming that initial psychological hurdle brings an immediate, powerful reward. Watching a patient transition from being nervous about insertion to experiencing unprecedented visual clarity—often the best vision they have had in living memory—is a truly transformative moment.

No Adaptation Period Required

With older generations of contact lenses, such as rigid gas permeable (RGP) or traditional hard lenses, patients had to endure a lengthy, uncomfortable adaptation period. They had to slowly build up their wear time over weeks as the eye adjusted to the sensation of the lens.

Scleral lenses have completely eliminated this hurdle. Because they are incredibly comfortable from the moment they touch the eye, there is virtually no physical adaptation period. First-time wearers can literally wear their scleral lenses all day, from day one, allowing you to enjoy crystal-clear vision immediately.
