Abstract
Objective and method

To describe a surgical technique that enables diffractive lenses with open-loop haptics to be centered on the chosen optical axis. To perform this, the desired axis must initially be marked on the cornea, the rhexis must be aligned with this, and once the intraocular lens (IOL) is implanted in the capsular bag, it is aligned by intracapsular rotation to match the central ring of the IOL with the corneal mark. Centering by simple optical lateral mobilization is often ineffective.

Conclusion

The described technique is easy to perform, allowing more precise focusing than the classic lateral mobilization technique used.

Keywords:

Resumen
Objetivo y método

Describir una técnica quirúrgica que permite centrar las lentes difractivas con hápticos en open-loop sobre el eje ocular elegido. Para ello se marca inicialmente sobre la córnea el eje deseado, se alinea la rexis con este y, una vez implantada la lente difractiva en el saco capsular, se alinea mediante rotación intrasacular hasta hacer coincidir el anillo central con la marca corneal. El centrado por simple movilización lateral de la óptica resulta frecuentemente ineficaz.

Conclusiones

La técnica de rotación descrita es una técnica fácil de realizar que permite un centrado más preciso que la clásicamente usada técnica de movilización lateral.
