Abstract
Purpose:
To investigate the rotational stability of plate-haptic toric intraocular lenses (IOLs) during 3-month follow-up.
Setting:
Eye and ENT Hospital of Fudan University, Shanghai, China.
Design:
Prospective observational study.
Methods:
Patients with cataracts implanted with AT TORBI 709M toric IOLs were enrolled and followed at 1 hour, 1 day, 3 days, 1 week, 2 weeks, 1 month, and 3 months postoperatively. A linear mixed model of repeated measures was applied to investigate the time course of absolute IOL rotation change. The 2-week overall IOL rotation was analyzed in the age, sex, axial length (AL), lens thickness (LT), preexisting astigmatism, and white-to-white subgroups.
Results:
A total of 328 eyes of 258 patients were included. The rotation from the end of surgery to 1 hour and 1 day to 3 days was significantly smaller compared with the rotation from 1 hour to 1 day but more than that at other time intervals in the overall group. 2 weeks postoperatively, the mean uncorrected distance visual acuity and remaining positive cylinder were 0.19 ± 0.22 logMAR and 0.60 ± 0.44 diopters, respectively. Significant between-group differences in 2-week overall rotation were found in the age, AL, and LT subgroups.
Conclusions:
Maximum rotation occurred within 1 hour to 1 day postoperatively, and the first 3 days postoperatively was a high-risk period for the plate-haptic toric IOL rotation. Surgeons should make the patients aware of this.
