When it comes to treating acanthamoeba keratitis, medication plays a crucial role in combating the infection and promoting healing. Various types of eye drops, ointments, and oral medications are prescribed to effectively manage this condition.
Types of Medications
Below are some common medications used in the treatment of acanthamoeba keratitis:
Antifungal Eye Drops: These eye drops contain antifungal agents that help to eliminate the Acanthamoeba organisms causing the infection. They are typically administered several times a day for a specific duration determined by the healthcare professional.
Antibacterial Eye Drops: Antibacterial eye drops may be prescribed to prevent secondary bacterial infections that can occur as a result of the damaged cornea. These eye drops work to combat bacteria and minimize the risk of further complications.
Corticosteroid Eye Drops: In some cases, corticosteroid eye drops may be recommended to reduce inflammation and promote healing. These drops are usually used alongside antifungal eye drops and under close supervision to avoid potential side effects.
Oral Antifungal Medications: Oral antifungal medications may be prescribed for severe cases of acanthamoeba keratitis. These medications work systemically to target and eradicate the Acanthamoeba organisms from the body.
It is important to follow the prescribed medication schedule and dosage instructions provided by the healthcare professional. Compliance with the treatment plan is crucial for effective management of acanthamoeba keratitis.
- Medication Type
- Antifungal Eye Drops
- Antibacterial Eye Drops
- Corticosteroid Eye Drops
- Oral Antifungal Medications
Usage
- To eliminate Acanthamoeba organisms
- To prevent secondary bacterial infections
- To reduce inflammation and promote healing
- For severe cases of acanthamoeba keratitis
Common Examples
- Propamidine Isethionate, Polyhexamethylene Biguanide (PHMB)
- Levofloxacin, Moxifloxacin Prednisolone Acetate, Dexamethasone Voriconazole, Fluconazole
It’s important to note that the specific medication regimen may vary depending on the severity of the infection and the individual’s overall health condition. Close monitoring by an ophthalmologist is necessary to ensure the most appropriate and effective treatment plan is implemented.
Acanthamoeba Keratitis Surgery
In severe cases of acanthamoeba keratitis, surgical intervention may be necessary to manage the infection and restore vision. Two common surgical procedures used are corneal transplantation and therapeutic keratectomy.
Corneal Transplantation
Corneal transplantation, also known as keratoplasty, involves replacing the damaged cornea with a healthy donor cornea. This procedure is typically recommended when the infection has caused significant damage to the cornea, leading to vision impairment or loss. Effective Acanthamoeba Keratitis Treatment Options
The surgery begins with removing the diseased cornea and replacing it with the donor cornea. Sutures are used to secure the transplant, and eye drops or ointments are prescribed to aid in the healing process. Over time, the transplanted cornea integrates with the surrounding tissue, improving vision clarity and reducing discomfort.
Note: Corneal transplantation carries certain risks, such as the possibility of graft rejection or infection. Patients should follow their surgeon’s post-operative instructions carefully and attend regular follow-up appointments to monitor the progress of the transplant.
Therapeutic Keratectomy
Therapeutic keratectomy is a surgical procedure that involves removing the diseased tissue from the cornea. It is often used when the infection has penetrated deep into the cornea and is resistant to other forms of treatment.
During the procedure, the surgeon carefully removes the affected layers of the cornea, eliminating the source of infection. Once the infected tissue is removed, antibiotic or antifungal medications may be applied directly to the cornea to eradicate any remaining traces of the infection.
Following therapeutic keratectomy, the eye is covered with a protective contact lens to aid in healing. Eye drops or ointments may also be prescribed to reduce inflammation and promote recovery.

Acanthamoeba Keratitis Prevention and Management
In order to reduce the risk of acanthamoeba keratitis, it is crucial to adopt preventive measures and implement effective management strategies. This will help safeguard individuals who are at higher risk or have a history of the infection.
Preventive Measures
Proper contact lens hygiene: Ensure that you clean your contact lenses thoroughly and follow recommended guidelines for lens storage and maintenance.
Avoid water exposure: Do not wear contact lenses while swimming, showering, or participating in water- related activities. Acanthamoeba can be present in water sources, including tap water.
Use of clean water: Use only sterile saline or contact lens solution approved by your eye care professional to rinse and store your contact lenses.
Avoid eye makeup contamination: Replace eye makeup products regularly and avoid sharing them with others to reduce the risk of introducing harmful microorganisms to the eyes.
Protective eyewear: Wear goggles or other appropriate protective eyewear when engaging in activities that may cause eye exposure to potentially contaminated water or soil.
Management Strategies
For individuals who have been diagnosed with acanthamoeba keratitis or are at higher risk due to specific factors, effective management strategies can help control the infection and prevent complications. These strategies may include:
Prompt medical attention: Seek immediate medical care if you experience symptoms such as eye pain, redness, blurred vision, or increased sensitivity to light.
Prescribed medications: Follow your healthcare professional’s instructions regarding the use of prescribed
medications, such as antiseptic eye drops, to combat the infection. Effective Acanthamoeba Keratitis Treatment Options
Frequent eye examinations: Regularly visit your eye care professional for comprehensive eye examinations to monitor the progress of the infection and adjust the treatment plan accordingly.
Adherence to hygiene practices: Maintain good eye hygiene by washing your hands thoroughly before handling contact lenses or touching your eyes.
Timely replacement of contact lenses: Replace your contact lenses as recommended by your eye care professional to prevent the accumulation of debris or microorganisms on the lenses.
By incorporating these preventive measures and management strategies into your daily routine, you can minimize the risk of acanthamoeba keratitis and ensure the well-being of your eyes.

- Proper contact lens hygiene
- Avoid water exposure
- Use of clean water
- Avoid eye makeup contamination Adherence to hygiene practices Protective eyewear Timely replacement of contact lenses
Acanthamoeba Keratitis Care and Therapy
In the comprehensive treatment of acanthamoeba keratitis, it is vital to emphasize the significance of holistic care and targeted therapy. Alongside medication and surgical interventions, adopting specific supportive measures can aid in managing the condition and facilitating a faster recovery.
One essential aspect of acanthamoeba keratitis care is the use of artificial tears. These lubricating eye drops help alleviate discomfort, reduce dryness, and promote healing. Artificial tears provide maximum hydration to the eyes, creating a protective barrier and minimizing the potential for further complications.
In addition to using artificial tears, practicing proper eye hygiene is crucial in preventing the recurrence and spread of acanthamoeba keratitis. Following strict hygiene practices, such as avoiding contact lens wear during treatment, properly cleaning and disinfecting lenses, and regularly replacing lens cases, can significantly reduce the risk of reinfection.
Moreover, consulting with a healthcare professional or eye care specialist is essential for receiving individualized guidance and reassessment of the treatment plan. These experts can provide tailored advice on symptom management, aid in optimizing medication usage, and monitor the progress of therapy.
