RUBIO CUEVAS, Mª Isabel; ALIO SANZ, Jorge L.  and  LOBATO CANON, José R.. Calidad de visión y satisfacción del paciente usuario de pantallas de visualización de datos tras cirugía refractiva. Med. segur. trab. [online]. 2007, vol.53, n.206, pp.33-39. ISSN 1989-7790.

Purpose: To evaluate the influence in quality of vision and satisfaction of video display terminal (VDT) users related to improvement of visual functions following excimer laser in situ keratomileusis (LASIK).  Methods: Longitudinal and observational study in a population of 96 patients that underwent LASIK using a questionnaire made for that, applied before and after surgery by an independent observer.  Results: Visual acuity and ocular refraction have improved after LASIK, being the efficiency index 1.1.  Contrast sensitivity postoperative improved at all spatial frequencies in the right eye (6 c/g, 3 c/g and 1 c/). While in the left eye there were no significant differences.  Quality of vision with and without correction is also better after LASIK (p < 0.05). And 84.38 % of patients would repeat themselves and recommend this surgery to other patients.  Conclusions: The results show that LASIK improves visual function and quality of life of patients.
