Determination of the effect of the assessment orthoptics and visual training before and after of laser corneal refractive surgery (Lasik)

Abstract

<em><strong>Objective:</strong></em> To establish the importance of valuation orthoptics and visual training before or after of the corneal refractive laser surgery, Lasik. <em><strong>Methods:</strong></em> 44 patients who underwent evaluation orthoptics and visual training before and after Lasik refractive surgery, attended in Optiláser and Ojos Láser Center, during a period of 12 months. We considered qualitative elements such as signs and symptoms and quantitative methods of evaluation as visual acuity for far and near vision, static and dynamic refraction, prism cover test for far and near vision, next point of convergence, flexibility and amplitude of accommodation, fusional reserves, stereopsis and sensory correspondence. <em><strong>Results:</strong></em> In assessing pre-and post-surgical 6 patients (13.63%) showed no eye motor alteration and 37 (84.09%) reported some kind of anomaly accommodates or motor, of whom 11 patients (29.72%) had abnormalities combined, 16 (43.24%) accommodative and 10 (37.03%) motor. In the pre-and post-operative frequencies Hirshberg had identical behavior. In the amplitude and flexibility of accommodation don’t found statistically significant differences (p> 0.05), before and after Lasik, albeit from a clinical point of view was evident increase in the alterations of high and moderate amplitude of accommodation after the refractive surgery, as is evidenced by the decrease normal values of the same, decreased flexibility in the eyes with normal values and increased disturbances at the higher levels and mild. Most patients had values altering of the fusional reserves positive for vision near and far between High Moderate. In the values of stereopsis, the ranges of normality were stable and high and moderate alterations were correlated with patients with strabismic or preexisting ocular abnormalities. The next point of convergence, the cover test and the status of Correspondence Sensory did not change. 100% of the patients who performed visual training reported improvement in their values as in clinical symptoms. Conclusions: Clinically Orthoptics the valuation is required in all patients who undergo refractive surgery, although no significant differences between the motor impairment and accommodating, clinically observed increase in the decompensation in the magnitude of the variables measured and increased symptoms.
