A Routine Morning Turns Alarming
For 39-year-old Groeschen, a typical morning quickly escalated into a medical emergency. Upon waking, he noticed irritation in his eye, which he initially dismissed as a minor issue. However, as days passed, the discomfort intensified, prompting him to seek medical attention.

At the Cincinnati Eye Institute, doctors diagnosed him with a severe eye infection caused by the bacterium Pseudomonas aeruginosa. This aggressive pathogen had taken hold beneath his contact lens, leading to a corneal ulcer—a painful open sore on the eye’s surface.

The Consequences of Overnight Contact Lens Wear
Groeschen’s habit of sleeping in his contact lenses, despite packaging claims that it was safe, was identified as the primary cause of his infection. While some lenses are marketed for extended wear, medical professionals caution against this practice.

The American Academy of Ophthalmology warns that overnight wear of contact lenses, regardless of type, significantly increases the risk of corneal infections. Dr. William Faulkner, who treated Groeschen, emphasized the importance of removing lenses before sleep to maintain eye health.

The Road to Recovery
Despite prompt medical intervention, the damage to Groeschen’s eye was irreversible. The infection led to scarring of the cornea, resulting in significant vision loss. To restore his sight, a corneal transplant was necessary—a procedure with a lengthy recovery period.
