Abstract Details



Purpose:

To show how a PRK procedure with the use of mitomycin can be a good tool to improve visual acuity (VA) in patients with residual scarring after an Acanthamoeba keratitis.

Setting:

Department of Ophthalmology, Hospital de Torrevieja and Centro Oftalmológico de Elche, Alicante, Spain.

Methods:

We present the case of a 31 years old male patient, with 4 diopters of myopia in both eyes. He was a wearer of weekly replacement hydrophilic contact lenses. We checked him in our clinic finding in one eye a pseudodendritiform keratitis that varied in shape during days and associated perineuritis. After stablishing the diagnosis of Acanthamoeba keratits, treatment was started with propamidine isethionate and topical steroids. Treatment was tapered down while the inflammation of the eye and the other findings were improving, completing the follow up after 10 months. At this point there was a residual corneal scarring with a corrected VA of 0.2 LogMar (-2.50 -2.00 x 175ẃ) that was treated by PRK.

Results:

PRK treatment was uneventful, using 0.02% mitomycin for 2 minutes. The corneal scarring was decreased and the patient achieved a final uncorrected VA of 0.1 LogMar.

Conclusions:

PRK is a procedure able to treat residual corneal scarring after an Acanthamoeba keratits, if this is superficial. Mitomycin association was used to reduce the risk of postoperative haze. The authors have no financial interest in any of the products mentioned in the article.
