Purpose: To assess posture-induced ocular cyclotorsion in eyes undergoing conventional cataract surgery (CCS) with intraocular lens (IOL) implantation using the VERION Image-Guided System (Alcon).

Methods: Patients with cataracts scheduled for conventional phacoemulsification with IOL implantation were consecutively examined and recruited into the study. All cataract surgeries were performed in December 2023 in the Department of Ophthalmology at the Military Institute of Aviation Medicine (Warsaw, Poland). The degree and direction of ocular cyclotorsion were recorded using the VERION Image-Guided System by comparing preoperative images of the anterior segment of the eye, captured with the patient seated, with intraoperative images obtained in the supine position. In addition, the correlation between axial length (AL) and ocular cyclotorsion was analyzed.

Results: The study included 31 eyes of 31 patients (20 women and 11 men). The mean age was 71.35 ± 8.48 years (range, 49–90 years), and the mean AL was 23.59 ± 1.59 mm (range, 20.44–29.22 mm). The mean absolute value of ocular cyclotorsion was 4.26 ± 3.04° (range, 0–11°; median, 4°). Clockwise rotation occurred more frequently (61.29%; 19 eyes) than counterclockwise rotation (35.48%; 11 eyes). Incyclorotation (54.84%) was more common than excyclorotation (41.94%). There was no significant correlation between AL and the degree of ocular cyclotorsion, Spearman’s rank correlation coefficient was ρ=0,14.

Conclusions: Posture-related cyclotorsion commonly occurs during CCS and may influence the accuracy of astigmatism correction by affecting the alignment of toric IOLs. The VERION Image-Guided System enables precise assessment and compensation of ocular cyclotorsion during cataract surgery.
