Abstract Details

Purpose:

To investigate ideal parameters for predicting postoperative intraocular lens (IOL) position in femtosecond laser-assisted cataract surgery (FLACS) using 3 dimensional optical coherence tomography (3D-OCT)

Setting:

86 eyes that underwent FLACS and implantation of a one-piece intraocular lens were examined to seek a new preoperative biometric parameter to improve our ability to predict the IOL position defined as the postoperative anterior chamber depth (post-ACD). The Catholic University of Korea, Seoul St. Mary's hospital

Methods:

Preoperative axial length was measured by the partial coherence interferometry. (IOLMaster) AD(aqueous depth), ACD(anterior chamber depth), LT(lens thickness), and LMP(lens meridian parameter) were measured by Catalys 3 dimensional optical coherence tomography (3D OCT). After phacoemulsification, 1-piece hydrophobic acryl IOL (Tennis ZCB00, AMO) was implanted in the bag. The post-ACD:ELP (effective lens position) was measured by Catalys 3D-OCT at 6 months postoperatively and was analyzed by Pearson correlation tests and multiple linear regression test.

Results:

The mean values of AD, ACD, LMP and LT were 2.67 ± 0.42, 3.28 ± 0.40 mm, 4.11 ± 0.34 mm and 4.26 ± 0.46 mm,respectively. The ELP was 4.59 ± 0.42 mm postoperatively. The LMP was highly correlated with ELP by Pearson tests. (r=0.675, p<0.01) Multiple regression analysis also demonstrated that LMP combined with AL showed the highest consistency with ELP.

Conclusions:

The LMP combined with AL was the best parameters for the prediction of ELP than any other measurements. The LMP is effective parameter for IOL power calculation in FLACS.
