HELPFUL HINTS FOR PLACING HYDROGEL LENSES ON THE EYE Often when the lens is first placed on the eye it will be uncomfortable. This may be only a slight irritation. If the patient seems uncomfortable at all it is very likely due to a small foreign body under the lens. The easiest and quickest way to correct this is to have the patient look nasally, get good control of the lids, and by placing the index finger on the lens, slide the lens onto the conjunctiva and move it in a circular motion. The lens can either be slid back onto the cornea or the lids released and the patient allowed to blink the lens back onto the cornea.
