Managing Risks: Safe Contact Lens Wear and Care to Avoid Complications

HEALTHY CONTACT LENS WEAR AND CARE: UNDERSTANDING POTENTIAL COMPLICATIONS AND PREVENTION

As an essential tool for vision correction, contact lenses offer a wide range of benefits. However, they also come with risks that cannot be overlooked. One primary concern is keratitis, inflammation of the cornea the clear layer covering the eye's colored part, which can occur at higher rates in contact lens users due to poor care practices.

Microbial keratitis stands as a critical concern linked to contact lens use. This type of infection arises when pathogensviruses, bacteria, fungi, or parasites such as amoebae invade the corneaoften through improperly handled lenses or exted wear periods. Microbial keratitis is particularly severe and can result in vision loss, even necessitating a corneal transplant in extreme cases.

Types of microbial keratitis:

1. Bacterial keratitis: An infection caused by bacteria.

2. Fungal keratitis: An inflammatory condition due to fungal invasion.

3. ParasiticAmebic keratitis: Infections brought about by parasitic amoebae.

4. HSV Herpes Simplex Virus keratitis: An infection resulting from the herpes simplex virus.

Symptoms of microbial keratitis:

• Irritated or red eyes

• Severe eye pn even after removing contacts

• Increased sensitivity to light

• Blurry vision that worsens rapidly

• Excessive watering or discharge

If experiencing any of these symptoms, promptly remove your lenses if worn and consult an ophthalmologist immediately.

Potential complications:

While most contact lens-related issues are mild and treatable without significant concern, they can still impact dly activities. These might include:

1. Dry eyes

2. Eye allergies

3. Giant Papillary Conjunctivitis: elevated conjunctival tissue on the inner eyelid

4. Corneal abrasion: a scratch or scrape on the cornea

5. Contact Lens-induced Acute Red Eye CLARE: redness and irritation in the eye from improper lens wear

6. Corneal infiltrates: signs of inflammation and potential infection within the cornea

7. Neovascularization: new blood vessel growth on the cornea causing redness

Prevention strategies:

Proper eye care practices are vital for preventing complications, including microbial keratitis. Regularly checking with your ophthalmologist can also ensure that you're using safe lens products and wearing techniques.

If symptoms of eye irritation occur:

• Immediately remove contact lenses

• Avoid wearing contacts until advised by a healthcare professional
