Abstract Details

Purpose:

To compare the clinical outcome of digital and manual marking for toric intraocular lens alignment.

Setting:

University Eye Clinic of Trieste, Italy

Methods:

20 cataract astigmatic patients were included. Patients were randomly assigned to either digital image guided marking using VERION digital marker (Alcon Laboratories, Ft. Worth, TX) or manual slit lamp-assisted preoperative marking using pendulum-attached marker. Patients underwent uneventful cataract surgery. At one week and at 6 months postoperatively uncorrected distance visual acuity, best corrected distance visual acuity, and toric IOL misalignment using the Nidek Refractive Power/Corneal analyzer, OPD –Scan III were evaluated.

Results:

The mean postoperative uncorrected distance visual acuity was 0,07±0,09 logMAR in the digital marking group and 0.10±0.08 logMAR in the manual marking group. The mean postoperative toric IOL misalignment was 3°± 2,6° in the first group and was 6.3°±3.1° in the second group.

Conclusions:

Accurate alignment of toric IOLs is important to achieve the desired astigmatism correction. VERION system has the advantage of preoperative planning and intraoperative digital guidance of the toric IOL alignment. The use of VERION system resulted in less postoperative deviation from the induced astigmatism target and showed less postoperative toric IOL misalignment than using manual-marking technique.
