Es una prueba refractiva objetiva cuyo prop\u00f3sito es determinar la curvatura, potencia y toricidad de la c\u00f3rnea. Se realiza con un querat\u00f3metro (kerat\u00f3metro) y debe hacerse sin correcci\u00f3n en ambos ojos.<\/span><\/div>\n
<\/div>\n
Las partes a usar de un querat\u00f3metro son:<\/span><\/div>\n
Ocular ajustable<\/span><\/div>\n
Ment\u00f3n ajustable y apoyo frontal<\/span><\/div>\n
Mando para enfocar y alinear querat\u00f3metro al ojo del paciente.<\/span><\/div>\n
Ajustes de meridianos principales y eje con sus escalas de indicaci\u00f3n.<\/span><\/div>\n
<\/div>\n
Preparaci\u00f3n<\/span><\/div>\n
Pedir al paciente que se quite sus lentes<\/span><\/div>\n
Ajustar ret\u00edcula a visi\u00f3n del optometrista. Que los aros conc\u00e9ntricos negros se vean claramente:<\/span><\/div>\n
<\/div>\n
<\/a><\/div>\n
<\/div>\n
<\/div>\n
Acomodar al paciente ajustando la altura de la silla y acercar o alejar el querat\u00f3metro a una distancia adecuada.<\/span><\/div>\n
Pedir al paciente que coloque sus brazos por encima de la base del querat\u00f3metro y hacer que su barbilla quede en la mentonera y su frente en el apoyo frontal. El paciente debe quedar c\u00f3modo.<\/span><\/div>\n
Alinear cantos del paciente verticalmente con las l\u00edneas marcadas para ello. De igual forma, con el mando de ajuste del querat\u00f3metro, elevarlo para que tambi\u00e9n quede verticalmente alineado con los cantos.<\/span><\/div>\n
<\/div>\n
Procedimiento<\/span><\/div>\n
Enfocar hasta que se logren ver claramente los aros indicadores blancos\/amarillos.<\/span><\/div>\n
<\/div>\n
<\/a><\/div>\n

 <\/p>\n

<\/a><\/div>\n
<\/div>\n
<\/div>\n
Centrar los aros conc\u00e9ntricos negros que se enfocaron inicialmente en el aro blanco inferior derecho.<\/span><\/div>\n
<\/div>\n
<\/a><\/div>\n
<\/div>\n
<\/div>\n
Poner el candado para evitar que el querat\u00f3metro se mueva.<\/span><\/div>\n
Ajustar meridianos horizontal y vertical as\u00ed como el eje, logrando que por el ocular se vea similar a la siguiente ilustraci\u00f3n:<\/span><\/div>\n
<\/div>\n
<\/a><\/div>\n
<\/div>\n
<\/div>\n
Anotar resultados, hasta cuartos de dioptr\u00eda (.00, .25, .50, .75), de la siguiente forma:<\/span><\/div>\n
<\/div>\n
K’= H\/V x eje del meridiano m\u00e1s plano* (ej: K’= 43.75\/42.00 x 75\u00b0)<\/span><\/div>\n
