Advanced Intraocular Lens Power Calculations.

The methodology for accurately calculating IOL power in normal and complex eyes has improved dramatically in recent years. Future advances are needed in all areas, including methods of measuring corneal power, predicting effective lens position, and perhaps even measuring axial length. The ultimate solution may be an IOL whose spherical and astigmatic power and higher order aberrations can be modified postoperatively. Ideally, such an IOL could be modified multiple times to adapt to the patient's changing visual needs and to compensate for aging changes of the cornea. [ABSTRACT FROM AUTHOR]
