Abstract Details

Purpose:

The primary objective of this prospective post-market follow-up study was to evaluate the visual outcomes and rotational stability of the new aspheric Aspira-aXA IOL (HumanOptics) with a large optic diameter (7 mm), an overall diameter of 11.0 mm and optimized plate haptics after implantation in cataract patients.

Setting:

Kepler University Hospital, Linz, Austria

Methods:

A total of 74 eyes with senile cataract and eligible for posterior chamber IOL implantation were targeted. The lenses were available in spherical powers of 10.0 to 25.0 D and were manufactured with a toric marking. Postoperative examinations included refraction, visual acuity, IOL stability and patient satisfaction. For evaluation of rotational stability, retro illuminated pictures were taken at the end of surgery (EoS) and 1-day, 1-week, 1-month, 4-month and 1.5-years postoperatively. The difference between the angle measured at baseline (EoS) and the angle measured at each follow-up was defined as the angle of rotation of the IOL.

Results:

At the time of submission, 74 eyes with a median AL of 23.42 mm (21.78 to 26.59) were implanted with the Aspira-aXA. At 4-month, median monocular UCVA and CDVA was 0.10 logMAR and -0.10 logMAR, respectively. The mean absolute IOL rotation (1-day vs EoS) was 2.55° ± 2.70 with only one eye showing IOL rotation > 10° (12.80°), which was associated with an AL of 26.45 mm and IOL power of 18.0 D. IOL rotation within the day after surgery was significantly higher compared to all other time-points (mean rotation < 2° between follow-ups). No IOL-related complications were reported.

Conclusions:

The Aspira-aXA with its large optic and cut-out haptics provided good visual performance and rotational stability. Consistent with the recent literature, postoperative IOL rotation usually occurs within the first day after surgery and larger amount of rotation, although rare, is often associated with axial length greater than 25.0 mm. Other risks also include increased intraocular pressure and incomplete viscoelastic removal after surgery.
