Poder dióptrico del lente intraocular y dilatación en pacientes con catarata / Dioptric power of intraocular lens and dilatation in patients with cataract
Resumen
Resumen
Introducción: la cirugía de catarata con implante de un lente intraocular es, hoy en día, el procedimiento quirúrgico más frecuente en todo el mundo. Su éxito depende de muchos factores, uno de los más importantes es el cálculo exacto del poder dióptrico del lente intraocular.
Objetivo: comparar el cálculo del poder dióptrico del lente intraocular en los pacientes sin y con dilatación pupilar.
Material y métodos: estudio longitudinal, en el que se determinó el cálculo del poder dióptrico del lente intraocular en pacientes con y sin dilatación pupilar. Las variables de estudio fueron: edad, género, ojo a estudiar, queratometría, longitud axial, profundidad de cámara anterior y poder dióptrico del lente intraocular. Se realizó estadística descriptiva y t de Student.
Resultados: se estudiaron 37 pacientes, 23 mujeres y 14 hombres. La edad promedio fue de 68 ± 7.87 años. Se estudiaron 64 ojos, 30 fueron derechos y 34 izquierdos. Estadísticamente solo hubo diferencia significativa en K2 de la biometría ocular entre pacientes sin y con dilatación pupilar al obtenerse un valor de p ≤ 0.05.
Conclusión: no existen cambios en el cálculo del poder dióptrico del LIO sin y con dilatación pupilar.
Abstract
Background: Cataract surgery with intraocular lens implant is, nowadays, the most frequent surgical procedure in all the world. Its success depends on a lot of factors, one of the most important is the calculation of the exact dioptric power of intraocular lens.
Objective: To compare the calculation of dioptric power of intraocular lens with and without dilatation in patients with cataract.
Material and methods: Longitudinal study, the calculation of the dioptric power of the intraocular lens was determined in patients without and with pupillary dilation. The variables were age, gender, eye to study, keratometry, axial length, anterior chamber depth and dioptric power of the intraocular lens. Descriptive statistics and Student t test were performed.
Results: There were 37 patients, 23 females and 14 males. The average age was 68 + 7.87 years. Sixty-four eyes were studied, 30 were right and 34 left. Statistically, there was only significant difference in K2 of the ocular biometry between patients without and with pupillary dilation when obtaining a value of p < 0.05.
Conclusion: There are no changes in the calculation of the dioptric power of the Intraocular lens without and with pupillary dilation.
