“…Many reported cases of microbial keratitis associated with orthokeratology are caused by Pseudomonas aeruginosa, [10][11][12] but Acanthamoeba is now becoming recognized as another possible cause [6][7][8][9][13][14][15][16]. Our report also demonstrates that overnight orthokeratology may induce Acanthamoeba keratitis.…”

“…No significant difference was recognised in the bacterial binding ability to the corneal epithelium between the overnight wear of either conventional or hyper-oxygen transmissible rigid contact lenses. 81 However, central corneal epithelial thinning with visual impairment 82 and the increased risk of bacterial 83,84 and Acanthamoeba keratitis [84][85][86][87][88][89] were reported with the overnight wear of orthokeratology contact lenses.…”

Contact lens wear is highly influential on the incidence of ulcerative keratitis worldwide, particularly in developed countries. The association between Acanthamoeba keratitis and contact lens wear is firmly established; it may account for up to 95% of the reported cases. Before the popularisation of soft contact lens wear, Acanthamoeba keratitis was extremely rare. In 2000 it was estimated that the number of contact lens wearers worldwide was about 80 million, out of whom 33 million were in the United States and 90% of them wore hydrogel soft lenses. Contact lens-related problems depend on many factors, such as lens material, wearing modality, lens hygiene, type of lens-caring solution, the degree of compliance of the lens user with lens wear and care procedures, lens overwear, sleeping in lenses, rate of changing lenses, and lens case hygiene. This paper is a thorough review of the literature aiming to highlight the role of one of the main risk factors of infectious keratitis, contact lens wear, and also to show the responsibility of lens users in aggravating this risk. RESUMENLa utilización de lentes de contacto es un factor que influye sumamente en la incidencia de la queratitis ulcerosa, en particular en los países desarrollados. La asociación entre queratitis por Acanthamoeba y el uso de lentes de contacto está firmemente establecida; podría representar aproximadamente hasta un 95% de los casos registrados. Antes de la popularización del uso de lentes de contacto, la queratitis por Acanthamoeba era muy poco frecuente. En el año 2000 se estimó que, a nivel mundial, había unos 80 millones de usuarios de lentes de contacto, de los cuales 33 millones residían en los Estados Unidos y, de ellos, el 90% utilizaban lentes de contacto blandas de hidrogel. Los problemas derivados del uso de lentes de contacto dependen de otros muchos factores, como el material del que está hecha la lente, la modalidad de uso, las medidas de higiene empleadas, el tipo de solución utilizada para la limpieza y el mantenimiento de la lente, el grado de cumplimiento terapéutico del usuario de las lentes respecto a su utilización y a su limpieza/mantenimiento, el uso de las lentes durante periodos excesivamente prolongados, el dormir con las lentes de contacto puestas, la frecuencia con la que el usuario se cambia de lentes y la limpieza de la funda de las lentes de contacto. Este artículo presenta una revisión minuciosa de la literatura, con el objetivo de resaltar el papel de uno de los principales factores de riesgo de desarrollo de queratitis infeccionsa, como es el uso de lentes de contacto, y con el fin de poner de relieve que el propio usuario de las lentes es, en ocasiones, el responsable de agravar este riesgo.

Is Corneal Refractive Therapy a New Modality Whose Time Has Come or Repackaged Orthokeratology Whose Time Has Passed?

I was asked to evaluate corneal refractive therapy (CRT) as an experienced ophthalmologist, who is a corneal specialist. I reviewed the literature and listened to and talked with ophthalmologists, optometrists, and researchers using and studying CRT. I feel that CRT is safe and effective. It offers a nonsurgical option for patients who are not eligible for surgery, particularly because of age, or for those who want to correct myopia for daytime vision but do not want to have surgery or wear a contact lens. CRT can be a valuable option to provide patients in a refractive surgery practice.
