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.
