Esta mañana me ha llegado los nuevos trabajos aceptados por IOVS, y hay uno muy interesante del grupo de Oshika que creo os puede interesar a los de este subforo. Os pego el abstract:

Abstract
Purpose: This prospective study was conducted to compare axial length elongation in myopic children receiving long-term overnight orthokeratology (OK) treatment with those wearing spectacles as controls.Methods: Fifty-nine subjects were enrolled in this study. The OK group comprised 29 subjects, who matched the inclusion criteria for OK. The control group comprised 30 subjects, who also matched the inclusion criteria for OK, but preferred spectacles for myopia correction. Axial length was periodically measured for 5 years using a IOLMaster (Carl Zeiss Meditec, Dublin, CA), and the time course of changes were evaluated and compared between the groups.Results: Forty-three subjects (22 and 21 in the OK and control groups, respectively) completed the 5-year follow-up examinations. At baseline, the mean age was 10.04 ± 1.43 (mean ± SD) years and 9.95 ± 1.59 years, the spherical equivalent refractive error was -1.89 ± 0.82 D and -1.83 ± 1.06 D, and the axial length was 24.09 ± 0.77 mm and 24.22 ± 0.71 mm in the OK and control groups, respectively, with no significant differences between the groups. The increase in axial length during the 5-year study period was 0.99 ± 0.47 mm and 1.41 ± 0.68 mm for the OK and control groups, respectively, and the difference was statistically significant (P = 0.0236, unpaired t-test). The annual increases in axial length were significantly different between the groups for the first (P = 0.0002), second (P = 0.0476), and third years (P = 0.0385), but not for the fourth (P = 0.0938) and fifth years (P = 0.8633). There were no severe complications throughout the study period.Conclusions: The current 5-year follow-up study indicated that OK can suppress axial length elongation in childhood myopia.

Te recomiendo que lo leas detenidamente, y te darás cuenta de que metodológicamente deja mucho que desear, y que la conclusión es absolutamente falsa a la luz de sus propios resultados.
