Abstract Details

Purpose:

To evaluate early postoperative outcomes toric intraocular lens (T-IOL) implantation using surgical guidance system and anterior segment swept source coherence tomography (AS-OCT) for astigmatic axis orientation, and compare the results with those of T-IOL implantation with manual axis-marking method.

Setting:

Ryugasaki Saiseikai Hospital, Ibaraki, Japan

Methods:

Twenty-six eyes of 20 subjects undergoing cataract surgery with T-IOL implantation were included. Cylindrical power and axis were evaluated with AS-OCT (CASIA®, TOMEY, Japan) preoperatively. All surgeries were performed by a single surgeon with VERION® (Alcon, USA) surgical guidance assisted T-IOL alignment. Visual acuity and refraction were measured preoperatively and at 1 day, 1 week, and 3 month postoperatively. IOL misalignments were evaluated at 3 month postoperatively. These results were compared with those of other patients (65 eyes of 48 subjects) who underwent T-IOL implantation with the same method except manual axis alignment.

Results:

Uncorrected distance visual acuity (UDVA) at 3 month postoperatively was 0.10 ± 0.14 (mean ± SD) logMAR in the surgical guidance assisted group and 0.05 ± 0.15 logMAR in the manually aligned group. Corrected distance visual acuity (CDVA) at 3 month postoperatively was 0.02 ± 0.07 and 0.03 ± 0.07, respectively. Subjective astigmatism was 0.75 ± 0.56 and 0.77 ± 0.34 D, respectively. IOL misalignments were 5.4 ± 4.8 and 5.8 ± 4.8 degrees, respectively. There were no significant differences in UDVA, CDVA, subjective and objective astigmatism, and IOL misalignments between two groups.

Conclusions:

Early postoperative outcomes of surgical guidance assisted T-IOL implantation were equivalent to those of manually aligned T-IOL implantation, when cylindrical power and axis were evaluated with AS-OCT preoperatively.
