Inclusion criteria

Inclusion criteria: One-hundreds and ninety-five eyes of 195 patients who were scheduled to underwent cataract surgery and implantation of single-piece acrylic IOL was enrolled in this study.

Exclusion criteria

Exclusion criteria: Exclusion criteria were eyes with corneal disorders; eyes with vitreous opacity or retinal disease; eyes with ocular surface dryness; eyes scheduled for extracapsular or intracapsular cataract extraction; history of ocular surgery or inflammation; eyes with pseudoexfoliation; eyes with a pupil diameter < 4.0 mm after mydriasis; eyes with marked irregular corneal astigmatism; eyes with patient refusal; and any anticipated difficulties with examination or 2-months follow-up.

Design outcomes

Primary

Measure	Time frame
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

Measure	Time frame
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	—
