Losing a contact lens in the eye can be a startling experience, often leading to immediate concern. While the sensation of a missing lens can be unsettling, it is a common occurrence for contact lens wearers. Fortunately, this situation is rarely a cause for serious panic and can typically be resolved with calm and appropriate action.
Where Lost Contacts Go
A common misconception is that a contact lens can get “lost behind the eye.” The anatomy of the eye prevents this from happening. The conjunctiva, a thin membrane, lines the inner surface of the eyelids and folds back to cover the white part of the eyeball (sclera). This continuous barrier makes it physically impossible for a contact lens to travel behind the eye.
Instead, a dislodged contact lens moves to accessible areas. It might fold in half or shift under the upper or lower eyelid. Occasionally, it can migrate to the corner of the eye. The lens always remains on the surface of the eye, allowing for its retrieval.
Immediate Steps for Removal
If a contact lens feels lost, remaining calm is the first step. Begin by thoroughly washing your hands with soap and water and drying them with a lint-free towel to prevent introducing bacteria or debris. Next, use a mirror in a well-lit area to help locate the lens.
If the lens is visible, gently slide it to a position where it is easier to grasp, such as the white of the eye. If the lens seems stuck or dry, apply a few drops of sterile saline solution, contact lens rewetting drops, or multipurpose solution to lubricate the eye and the lens. Close your eye and gently massage your eyelid to encourage the lens to move. Blinking frequently after applying drops can also help to dislodge the lens.
Potential Eye Irritation and Complications
While a lost contact lens cannot go behind the eye, it can cause discomfort and irritation. A dislodged or dried-out lens can lead to a foreign body sensation, feeling like something is in your eye. This can be accompanied by redness, excessive tearing, or a burning sensation. The eye might also become sensitive to light.
If the lens remains in the eye for an extended period or if the eye is rubbed excessively, complications can arise. These include corneal abrasions, which are scratches on the clear outer surface of the eye. Corneal abrasions can be painful and may temporarily affect vision. Prolonged irritation or improper handling can increase the risk of eye infections like keratitis, an inflammation of the cornea. Untreated keratitis can lead to vision loss.
When to Seek Medical Attention
Recognize when a lost contact lens situation requires professional medical attention. If you experience persistent pain, severe redness, or discharge, consult an eye care professional. Other symptoms include blurry or decreased vision, increased light sensitivity, or the feeling that something is still in your eye after the lens has been removed.
If you have tried the immediate removal steps and are still unable to locate or remove the lens, or if your eye remains irritated for several hours after removal, seek help from an optometrist or ophthalmologist. Attempting to force a stuck lens out can cause further damage to the eye. An eye care professional can safely retrieve the lens and assess for damage, such as a corneal abrasion.
Preventing Future Incidents
Good contact lens habits can reduce the likelihood of a lens getting lost or stuck. Ensure contact lenses are properly fitted by an eye care professional, as ill-fitting lenses are prone to shifting. Always wash your hands thoroughly before handling lenses to avoid transferring oils or debris. Using rewetting drops throughout the day can keep lenses moist and prevent them from drying out and sticking.
Avoid vigorously rubbing your eyes, as this can dislodge a lens. Adhere to the recommended wearing schedule and never sleep in daily wear lenses, as this increases dryness and the chance of the lens sticking. Regularly cleaning your lenses and replacing your lens case as advised also contributes to eye health and reduces complications.
