Abstract Details


The effect of astigmatic correction in toric intraocular lens (IOL) changed according to effective lens position (ELP) after cataract surgery. And, the longitudinal movement of the IOL can tilt IOL after cataract operation. We evaluated relation between change of ELP and toric IOL rotation in patients with increasing residual astigmatism after successful toric intraocular lens (IOL) implantation.


Bucheon St. Mary’s Hospital, Catholic University of Korea, Seoul, Korea


The subjects include 61 people (61 eyes) with increasing residual astigmatism more than 0.5 diopter 2 months after successful toric IOL implantation. Clinical measurements included preoperative, 1-week, 1-month, and 2-month postoperative visual acuity, refraction, keratometer, anterior and posterior corneal astigmatism, and ELP by Scheimpflug camera imaging, IOL axis by slit-lamp biomicroscopic photograph with pupil dilation.


Residual astigmatism in postoperative 2-month (1.38 ± 0.50) is higher than postoperative 1-week (0.51 ± 0.38)(P<0.05). The ELP decreased by 264.44 ± 163.25 ㎛ and IOL rotated by 2.91 ± 1.44 degrees from 1-week to 2-month (P<0.05). The ELP change had positive correlation with IOL rotation (R2 = 0.61, P=0.006). And, the residual astigmatic change had positive correlation with ELP change (R2 = 0.52, P=0.027) and IOL rotation (R2 = 0.89, P=0.0001) from 1-week to 2-month.


ELP change can influence toric IOL rotation and increase residual astigmatism after toric IOL implantation.
