Microbial Keratitis Explained
Microbial keratitis is a serious eye infection that can occur in contact lens wearers. It arises when bacteria, fungi, or amoebas invade the cornea, potentially leading to vision loss or blindness if not treated promptly. This condition is particularly concerning for those who do not adhere to proper lens hygiene practices.
Factors contributing to microbial keratitis include poor hygiene, sleeping in lenses not designed for overnight wear, and exposure to contaminated water. The risk increases with prolonged lens wear, as microbes accumulate and can breach the corneal barrier.
| Risk Factor | Description |
|---|---|
| Poor Hygiene | Not washing hands or using expired solutions. |
| Water Exposure | Wearing lenses while swimming or showering. |
| Extended Wear | Keeping lenses on for too long increases infection risk. |
How Contact Lenses Affect Eye Biology
Contact lenses provide convenience and freedom from glasses but can increase the risk of serious eye infections if not cared for properly. Dr. Neeraj Sanduja emphasizes that the cornea, protected by a natural tear film, can be compromised by contact lenses, making it more prone to infections. Poor hygiene, infrequent blinking, and the insertion/removal process can lead to complications like microbial keratitis, a potentially sight-threatening condition.
Common Causes of Infections
- Not maintaining proper hygiene
- Sleeping with lenses on
- Wearing lenses while swimming or showering
- Wearing lenses for extended periods
To minimize risks, users should adhere to strict hygiene protocols, avoid water exposure, and follow eye care provider instructions. Regular eye exams can also help catch early signs of complications.
Factors Increasing Infection Risk
Contact lens users face heightened risks of eye infections due to several factors. Poor hygiene practices, such as not washing hands before handling lenses or using expired solutions, significantly contribute to the risk.
