More children select OK lens to control myopia. Corneal endothelial cells (CECs) were used to assess the safety of OK lens. We reported a unique case of CECs deficiency in a high myopic woman who wore OK lens for 8 years. She followed up irregularly and did not replace the lens in time. The lenses were covered with thick protein membrane and scratches. Her endothelial cells density (ECD) dropped significantly. It remained at low level until 3-year follow-up. In conclusion, there is a great need for patient education regarding the potential risks involved with the increasing popularity of OK lenses.
