Abstract Details

Purpose:

To evaluate the efficacy of toric multifocal intraocular lenses and peripheral limbal relaxing incisions(PCRIs) with multifocal intraocular lenses for correcting astigmatism after phacoemulsification.

Setting:

Sungmo eye hospital, Busan, Korea.

Methods:

Sixty nine eyes with cataract and coexisting topographic astigmatism were included in the study. Eyes were divided into two groups: 1) 34 eyes with toric multifocal IOL insertion, and 2) 35 eyes with limbal relaxing incisions with multifocal IOL. Postoperative refractive cylinder and higher-order aberration measured by KR-1W(Topcon Corp., Tokyo, Japan) 1month postoperatively.

Results:

There were no significant differences between the two groups in uncorrected distance visual acuity (UDVA), uncorrected near visual acuity (UNVA), corrected distance visual acuity (CDVA), and corrected near visual acuity (CNVA). The mean refractive cylinder was 0.51±0.43 D in group A, 0.46±0.39 D in groupB. But those two values did not show significant difference statistically (p = 0.563). The results obtained by KR-1W, total high order abberation (p=0.016), spherical aberration (p = 0.039), and RMS (p=0.021) were statistically significantly smaller in group A than group B.

Conclusions:

Toric IOLs and PCRIs both reduced astigmatism. Compared to limbal relaxing incisions with multifocal IOL insertions, toric multifocal IOL insertions produced better results with high order aberration change.
