Purpose:

To compare the astigmatic outcomes of toric IOL implantation obtained using iris registration guided femtosecond laser capsular marks with those using steep axis intrastromal corneal marks combined with intraoperative aberrometry during cataract surgery.

Methods:

This retrospective study included 52 eyes with cataract and pre-existing astigmatism who had undergone toric IOL implantation (TECNIS Symfony® Toric Extended Depth of Focus IOL) using femtosecond laser assisted cataract surgery. In group A, toric IOLs were aligned using iris registration-guided capsular marks (CMs) with automatic cyclotorsion compensation (IntelliAxis-L, LENSAR). In group B, toric IOLs were aligned using intrastromal corneal marks (IntelliAxis-C, LENSAR) and intraoperative aberrometry (ORA™, Alcon).

Results:

Data are being collected. Preliminary results show that astigmatic outcomes obtained using CMs are better than those obtained using intrastromal corneal marks and intraoperative aberrometry. No complications have been observed till date.

Conclusions:

Femtosecond laser-assisted capsular marks facilitate precise alignment of toric IOL on the predefined axis of implantation, thus allowing for effective management of astigmatism with toric IOLs.
