Resumen
El propósito del estudio fue comparar la recuperación de agudeza visual y
sintomatología del paciente post-operado de LASIK, estudiando la efectividad de dos tipos
de compuestos de lágrimas artificiales, tomando en consideración los efectos secundarios
de esta intervención y su directa relación con el film lagrimal.
Hipótesis: Existe una diferencia de tiempo clínicamente significativo en la recuperación de
la agudeza visual post-LASIK acompañado de menor sintomatología, mejor comfort visual,
y restablecimiento de la lubricación ocular normal, al comparar Hialuronato de sodio al
0.4% y Glicerol al1% + Polisorbato 80 al1 %.
Objetivos: Determinar si el uso y la calidad de la lágrima artificial están relacionados con
la recuperación final de la agudeza visual, en un menor tiempo y disminuyendo la
sintomatología post- LASIK comparando dos tipos de compuestos.
Metodología: Se realiza un estudio comparativo, en la clínica Ultravisión Iquique que
contempla una muestra de 30 pacientes que se realizaron cirugía LASIK desde enero 2012,
hasta mayo 2012. A estos pacientes Post-cirugía se les recetaron dos tipos de lágrimas
artificiales, Hialuronato de sodio al 0.4% y Glicerol al 1% + Polisorbato 80 al 1%, en base
a su similitud con el film lagrimal fisiológico y se controlaron posteriormente en tres
controles.
Resultados: El promedio de las agudezas visuales finales utilizando Hialuronato de sodio
al 0,4% y glicerol+ polisorbato 80 al 1% fueron (promedio+ desviación estándar) 0,98 ±
0,13384278 y 1.0 ± 0,1117537 respectivamente. En cuanto a la compliance, no se nota
diferencia ocupando cualquiera de las gotas, obteniendo si, una diferencia en el comfort
visual de 63 % versus 33 % al utilizar glicerol + polisorbato 80 al 1%.
Conclusion: Al comparar las mediciones de la agudeza visual final con hialuronato de
sodio al 0,4% y glicerol + polisorbato 80 al 1%, se encontró que no hay una diferencia
significativa en la recuperación final de la agudeza visual post LASIK, siendo si notable el
aumento del confort visual del paciente al utilizar glicerol + polisorbato 80 al 1 %
The purpose of this study was to compare the recovery of visual acuity and patient's symptoms ofpost-LASIK surgery, studying the effectiveness oftwo types of compounds of artificial tears, taking into consideration the side effects of this intervention and its direct relationship with the tear film. Hypothesis: There is a clinically significant time difference in the recovery of visual acuity post-LASIK accompanied by reduced symptoms, improved visual comfort and restoration of normal ocular lubrication, comparing sodium hyaluronate 0.4% and % glycerol + Polysorbate 80 1%. Objectives: To determine whether the use and quality of artificial tears are related to the final recovery of visual acuity, in less time and reducing post-LASIK symptoms comparing two types of compounds. Methodology: a comparative study in !quique Ultravisión clinic which provides a sample of 30 patients who underwent LASIK from January 2012 until May 2012. A Post-surgery patients were prescribed two types of artificial tears, sodium hyaluronate 0.4% and glycerol + Polysorbate 80 1%, based on its similarity to the physiological tear film and subsequently controlled in three controls. Results: The average final visual acuity usmg sodium hyaluronate 0.4% glycerol + polysorbate 80 1% were (mean ± standard deviation) 0.98 ± 1.0 ± 0.13384278 and 0.1117537 respectively. Asto the compliance, occupying not notice any difference drops, if obtaining a difference in the visual comfort of 63% versus 33% for glycerol polysorbate 80 + 1%. Conclusion: When comparing the measurements of visual acuity with sodium hyaluronate 0.4% glycerol + 1% polysorbate 80, we found no significant difference in the final recovery of visual acuity post-LASIK, where if marked increase visual comfort of the patient to use glycerol + polysorbate 80 1%
