Preparations for lens insertion (figure 13)
- Take the lens out of the lens case and rinse it with saline solution.
- Depending on the lens care system, wet the lens with the wetting solution.
- Hold the lens between thumb and index finger and fill the lens with sterile saline solution.
Insertion (figure 14)
- Bend forward so that you are facing the floor and look down towards your chin as much as possible.
- Use the index finger of your available hand to lift up the upper eyelid of the eye.
- Hold the lashes of your upper lid firmly against the rim of your brow. It is important that you keep your upper lid in this position whilst looking downward.
- Slide the edge of the lens under the upper lid and continue looking downwards.
- When the upper edge of the lens is in place, close the upper lid over the lens and keep in place with your index finger.
- Pull the lower lid out from under the lower edge of the lens, using a tissue to dry the eyelid if it is slippery.
- When the lens is in place under both eyelids, the eye may be opened.
Patients who have difficulty with this procedure might prefer the alternative method using a scleral lens suction holder.
Checking for air bubbles The presence of air bubbles should be avoided, as they can affect vision and irritate the eyes. If they are present, the lenses will need to be re-inserted.
Inspect the eye for the presence of air bubbles. A magnifying mirror and bright light are often used. Patients who are prone to getting air bubbles behind their lenses, may prefer to use a more viscous, unpreserved artificial tear solution to fill the lens before insertion.
