Abstract Details

Purpose:

Myopia is a spherical refractive error that causes light to focus in front of the retina: if it is not treated may cause severe complications. Orthokeratology lenses may reshape the cornea if worn overnight slowing down the progression of myopia in children. I assessed the efficacy of Esa Ortho-6 for the correction and the stabilization of myopia in children.

Setting:

Studio Oculistico Dr. Salvatore Giugno Viale Mario Gori 63, Niscemi (CL) Italia

Methods:

I enrolled 30 young patients aged between 11 and 20; all patients had a myopia ranged between -1 to -6 diopters. In 15 patients myopia was treated by spectacles correction, 15 patients were treated with the use of Esa Ortho-6 lenses at night. I evaluated pre-treatment anterior segment tomography (CSO- Sirius), UCVA, BCVA, spherical equivalent, axial length (Zeiss IOL Master), over refraction with orthokeratology lenses fitted; I evaluated anterior segment tomography (CSO- Sirius), UCVA, BCVA, axial length (Zeiss IOL Master), over refraction with lenses fitted at one week, one month, 3, 6, 12, 24 months of orthokeratology therapy.

Results:

I assessed that orthokeratology treatment decreases the rate of myopia progression in terms of reduction in axial length increase compared to the correction of glasses in young patients. The obtained p value is <0.001. Orthokeratology treatment is associated with a remodeling of the cornea that changes from a prolate form to an oblate one and a certain number of high order aberrations are induced: coma as aberration, spherical aberration, second order aberration.

Conclusions:

Orthokeratology is effective in reducing the rate of myopia progression: this is in agreement with reference literature. Although there is small risk of vision-threating complications (corneal keratitis), orthokeratology may be offered to young patients with moderate to high myopia.
