| Resumo: | This thesis presents some of the changes occurring in the accommodative function and binocular vision after corneal and intraocular refractive surgery and also discusses some strategies to avoid potentially adverse complications associated with imbalance in the accommodative and binocular system. Aspects as accommodation, aging effect, neural and brain processing, pupil diameter, and binocular vision should be considered at pre- and post-surgery stages hence these factors may affect the vision quality and efficiency, and consequently patient’s satisfaction. Binocular and accommodative function are affected after refractive surgery and can have an impact on the outcomes of the surgical procedure, particularly in high astigmatisms, myopia or hyperopia, anisometropia, monovision correction, myopic overcorrection, pre-presbyopes and early presbyopic patients. Binocular vision and accommodative assessment could help the surgeon in terms of preoperative advice and should be considered for every patient undergoing any refractive procedure.
