While it remains convenient and inexpensive, this is not as safe or simple as it may sound.īaby shampoos-as well as some eyelid cleansers-contain cocamidopropyl betaine, a surfactant and lathering agent that may cause an eyelid dermatitis. The “old-school” lid hygiene method included the use of diluted baby shampoo to remove debris and contaminants. Keeping the lids clean, which in turn keeps the lens clean, directly benefits patient comfort, safety and quality of vision. ![]() ![]() 5 Additionally, substantial lid bioburden is associated with a 2.5-fold greater risk of substantial lens bioburden, and is likely the major route of lens contamination. The lid margin, commonly colonized by microbes, is found to harbor organisms up to 70% of the time. Normal ocular organisms include coagulase-negative Staphylococci, Corynebacterium species, Micrococcus species, Bacillus species and Propionibacterium species. Bacterial contamination of soft lenses is associated with microbial keratitis and corneal inflammatory events. In addition to affecting the tear film, vision and comfort, the lids play host to myriad microorganisms. Once formed, these deposits impair optical quality and the wettability of the lens surface (with the latter resulting in a quick break-up of the tear film), which can eventually lead to intolerance to contact lens wear. Over time, lipids associated with the contact lens will become unstable and degrade. These lipid deposits may also be seen in those with no apparent MGD due to the individual composition of the meibum. This phenomenon is not limited to these patients, however. 2 Stable lipids don’t degrade and don’t cause discomfort or blur.īlepharitis and meibomian gland dysfunction (MGD) patients typically experience heavy deposits of lipids on their lenses. 1 Tear lipids are oxidatively stable in their native environment because meibomian glands predominantly secrete only saturated and monounsaturated lipids. As we’ve all seen clinically, patients who have blepharitis exhibit significant differences in tear physiology than those without blepharitis. It really is no secret that clean eyelids promote healthy contact lens wear. ![]()
