Brief summary

The objective of this trial was specifically aimed at answering the research question: For the general cataract population, does the use of partial coherence interferometry improve postoperative outcomes compared with current generation applanation ultrasound biometry, as measured by postoperative refractive error, by increasing the accuracy of calculation of the intraocular lens power.

Interventions

Preoperative biometry of axial length using partial coherence interferometry. This measurement is done at a single preadmission clinic visit.
