Abstract Details

Purpose:

To measure and compare sizing and positioning parameters of the precision pulse capsulotomy (PPC) with the femtosecond laser capsulotomy (FSLC) by Anterior segment optical coherence tomography (AS-OCT).

Setting:

Sungmo Eye Hospital, Busan, Korea

Methods:

Precision pulse capsulotomies (Zepto, Mynosys Inc., Fremont, CA) and Femtosecond laser capsulotomies (LenSx, Alcon, Fort Worth, TX) were carried out in 40 eyes, respectively. CCC diameters, circularity of capsulotomy, distance between the CCC and pupil center, and IOL horizontal tilting were analyzed using the AS-OCT.

Results:

Mean CCC diameter was 5.65±0.22mm in PPC group, and 5.90±0.25mm in FSLC group. Circularity of capsulotomy was 0.955±0.033 in PPC group and 0.973±0.039 in FSLC group and was statistically different between the 2 groups (p=0.032). The distance from the CCC center to the pupil center was 0.40±0.21mm in PPC group and 0.28±0.15mm in FSLC group. The CCC center was closer to the pupil center in FSLC than in PPC group (p=0.004). The IOL horizontal tilting was 0.63±0.47 ˚ in PPC group and 0.52 ± 0.43 ˚ in FSLC group.

Conclusions:

Continuous curvilinear capsulorrhexis created with femtosecond laser and precision pulse can be well-centered, accurate, round, and reproducible, with accurate diameters and resulted in a more stable refractive result and less IOL tilt and decentration.
