Abstract Details

Purpose:

To evaluate the efficacy of reverse geometry rigid LACs for the correction and stabilization of myopia in children. The orthokeratology lenses can reshape the cornea if worn during the night, slowing down the progression of myopia.

Setting:

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

Methods:

30 young patients aged between 11 and 20 were enrolled; 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.  Pre-treatment anterior segment tomography (CSO- Sirius), UCVA, BCVA, spherical equivalent, axial length (Zeiss IOL Master) and over refraction with orthokeratology lenses fitted were evaluated at one week, one month, 3, 6, 12, 24 months of orthokeratology therapy

Results:

Orthokeratology is based on a reshaping of the cornea, whose form changes from a prolate form into an oblate one inducing a number of high order aberrations: COMA, spherical aberrations and second order aberrations. Orthokeratology corrects myopia and decreases the index of myopic progression in terms of reduction of axial length growth compared to a correction with ophthalmic lenses in young patients. The p value obtained is <0.001

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.
