Purpose: To determine the frequency and microbiologic profile of contact lens (CL) related comeal ulcers and its relationship to contact lens type.

Methods: The clinical and microbiologic records of all patients presenting with comeal ulcers to the New York Eye and Ear Infirmary from January 1, 2003 to July 30, 2005 were retrospectively reviewed. All patients with CL related comeal ulcers were identified and information regarding lens type, usage, cultures, and other risk factors were recorded.

Results: 1499 cases of comeal ulceration were recorded. 125 of these were CL related (125/1499, 8%). 106 cases were culture positive and 19 culture negative. 76 patients were wearing frequent replacement lens, 8 daily disposable lenses, 7 therapeutic CL's, 5 gas permeable CL's, and 4 conventional soft CL's. 25 were wearing soft lens but the CL-type was not recorded in the chart. 51 patients admitted to sleeping in their lenses one to two evenings prior to their infection. The most common microorganisms isolated were in descending order S. epidermidis (26), P. acnes (20), S. aureus (20), P. aeruginosa (17), and S. marcesans (9). Polymicrobial infections were seen in 15 eyes.

Conclusions: The CL type most frequently associated with comeal ulcers was the soft daily-wear frequent replacement lens. The number of S. epidermidis and P. acnes ulcers and the number of polymicrobial infections was greater than is reported in the literature. Despite an industry shift to frequent replacement lenses eomeal ulcers continue to be a frequent problem.
