a) RE in each eye
b) Within-patient difference in RE (D) between the two eyes**
*For DSBCS surgery, we report the first eye then the second eye. For ISBCS surgery, we report the right eye then the left eye, although the actual order of surgery was not obtained for the study. Emmetropia was defined as −0.5 to 0 D.
**Chi-square, p<0.001.
Postoperative refractive error in 12,717 DSBCS patients and 3,243 ISBCS patients
Abbreviations: ISBCS, immediate sequential bilateral cataract surgery; DSBCS, delayed sequential bilateral cataract surgery; emme, emmetropia; ame ametropia.
