Not Applicable

• Conditions: cataract

• Registration Number: JPRN-UMIN000039844
• Lead Sponsor: Hayashi Eye Hospital

Brief Summary

The mean PE did not differ significantly among groups at 1 days and 1 month postoperatively, and were significantly less in the SN60WF group than in the XY-1 and ZCB00V groups at 2 months (P<.0006). The mean change in PE between 1 day and 2 months after surgery was significantly less in the SN60WF group than in the other groups (P=.0062).

Primary Outcome Measures

Name	Time	Method
Refractive prediction error (PE), and changes in PE was examined at 1 days, and 1 and 2 months postoperatively, and were compared among 3 IOL groups.

Secondary Outcome Measures

Name	Time	Method
To clarify the causes why did the changes in PE during 2 months after surgery differ among these IOLs, we examined the factors that significantly affect the changes in PE
