How should scleral lenses be inserted?

The correct method for inserting scleral lenses involves a specific technique to ensure proper positioning and comfort. Inserting a scleral lens directly onto the cornea is not the recommended approach; however, understanding how scleral lenses should be handled is essential.

Scleral lenses are larger diameter contact lenses that vault over the cornea and rest on the sclera, creating a fluid reservoir between the lens and the corneal surface. Proper insertion should occur by first filling the lens with a suitable saline solution, which aids in forming a tight seal once placed on the sclera. By inserting the lens onto the sclera rather than the cornea, this placement allows the lens to settle properly without initial contact with the cornea, minimizing potential discomfort and preventing damage.

The other methods mentioned would not provide the ideal approach for inserting scleral lenses. Inserting the lens in the inferior cul-de-sac or directly on the inferior sclera would not facilitate proper alignment or fit, while placing it on the medial canthus would not allow for effective placement and might result in a poor fit or misalignment of the optics of the lens, thereby reducing visual clarity and comfort.

By accurately understanding the intended design and application technique for scleral lenses, practitioners ensure optimal comfort and
