STILL CAN GET CORNEAL ULCERS W/ SILICONE HYDROGELS

Eye & Contact Lens: Science and Clinical Practice - Abstract: Volume 34(2) March 2008 p 124-128 Pseudomonas Keratitis Associated With Daily Wear of Silicone Hydrogel Contact Lenses.:

Keep in mind that we may still get corneal ulcers with silicone hydrogel lenses, even on a daily wear schedule. I'm interested to see studies done with Purevision and Night and Day contact lenses, and with 30 day continuous vs. daily wear.

"Increased oxygen permeability associated with silicone hydrogel contact lenses may reduce, but does not eliminate, the risk of pseudomonas keratitis. Studies have yet to quantify the risk of keratitis associated with daily wear of these lens materials. Further study is necessary to identify the risks of complications with daily wear of silicone hydrogel lenses and to determine which factors may contribute to those risks."
