UNLABELLED: Orthokeratology is reversible clinical procedure which can reduce myopia using contact lenses made of high gas permeable material with 4 curves reverse geometry shape.
PURPOSE: The aim of the paper is to evaluate vision acuity and progression of myo,ia and corneal curvature during use of overnight RGP lenses.
MATERIAL AND METHODS: The studies have been peforrmed in 132 patients (264 eyes) in age 5 - 18 years (average 12.5 years) with myopia from -1.50 Dsph to -5.50 Dsph and astigmatism from 0.25 Dsph to 1.25 Dsph. In all patients cornea radius (automatic keratorefractometer) and coreal refractive power (coreat topography) was measured before and after 3 months of we- se ot aring during night RGP lenses. Refraction was measured with the use of autokeratorefraktometer after 2 to 6 years of wearing lenses.
RESULTS: In all patients reduction of corneal refractive power (on average 3.05 Dsph) and increase of corneal radiuses (on average 0.4 mm) has been observed. After 2 to 6 years of wearing during night RGP lenses refraction was the same in 48.5% of children, worsened in 31.8% of -0.50 Dsph and progressed of -1.00 Dsph in 19.7% of patients.
CONCLUSION: Orthokeratology reduces myopia due to temporary changes in corneal curvature. orthokeratology, myopia, corneal radius, corneal topography.
