What is the recommended method for inserting scleral lenses?

Using a plunger is the recommended method for inserting scleral lenses. This technique is preferred because it allows for greater control and precision when handling the lens, reducing the risk of damaging the lens or causing discomfort. A plunger typically has a soft suction cup that can securely hold the lens without applying excessive pressure, which is particularly important given the size and shape of scleral lenses.

Inserting scleral lenses directly on the eye or using fingers may increase the risk of contamination and make it harder to achieve the proper positioning on the eye. These methods may also lead to discomfort if the lens does not center correctly upon insertion. While using saline solution to moisten the lens is beneficial, it is not a method of insertion itself but rather a preparatory step to enhance comfort during insertion.
