Purpose:
Purpose: To examine if ultrasound biomicroscopy has resolution and field of view capable to image the effect of the size of capsulorhexis and its overlap over the IOL optic on the axial position of the IOL.
Setting:
Private Practice
Methods:
This retrospective intraindividual study comprised 20 eyes of 10 patients after cataract surgery. Patients with similar ocular biometry in both eyes but more than 180 degrees (50%) difference in the amount of the capsulorhexis overlap over the IOL optic in the right eye as compared to the left eye were included in our study. Ultrabiomicroscopic images, pseudophakic anterior chamber depths and refractive outcome are compared in our study.
Results:
Ultrabiomicroscopic images of eyes with larger capsulorhexis and less overlap over the IOL optic compared to eyes with smaller capsulorhexis and more overlap are presented. IOLs with larger capsulorhexis showed an average anterior displacement of the IOL optic of 0.24 mm and an average myopic shift of 0.5 D.
Conclusions:
The size of the capsulorhexis has a clinically significant effect on the postoperative axial position of the IOL. Ultrasound biomicroscopy imaging has resolution and field of view to clearly show this effect. The possible causes of the shift of the IOL are analyzed. FINANCIAL DISCLOSURE?: No
