A Case of Bacterial Keratitis in a Patient Using Orthokeratology and Soft Contact Lenses.

A 63-year-old male with high myopia developed sudden visual loss, eyelid swelling, eye pain, discharge, and tearing in his left eye while wearing soft contact lenses (CLs) during the day and orthokeratology lenses at night. At the initial visit, his corrected visual acuity in the left eye was 20/1000, with a ring-shaped ulcer in the central cornea, corneal infiltration across the entire cornea, and conjunctival hyperemia. was detected from corneal scrapings, and after antibiotic treatment, the ulcer healed with corneal opacity remaining. On the 60th day, corrected visual acuity of 20/20 was achieved with rigid gas-permeable CLs. To prevent CL-related ocular complications, eye care professionals must carefully evaluate the suitability of all CLs, including orthokeratology.
