Abstract:
PURPOSE: The goal of the present study was to compare the stability of the 3-piece (Tecnis ZA9003) and single-piece (AcrySof IQ) aspheric intraocular lenses (IOL) by testing decentration, tilt, anterior chamber depth, and refraction. METHODS: The subjects of this study consisted of 101 eyes who had undergone cataract surgeries with a 3-piece aspheric IOL (54 eyes) and with a single-piece aspheric IOL (47 eyes). The decentration, tilt, anterior chamber depth, and refraction were measured on postoperative day 1, 1 month, and 2 months, using an anterior eye segment analysis system (EAS-1000, Nidek, Japan). RESULTS: There was a statistically significant difference in the decentration on the postoperative day 1 (p = 0.04). However, there was no statistically significant difference on postoperative 1 month (p = 0.15) and 2 months (p = 0.13). There was no statistically significant difference in the tilt on postoperative day 1, 1 month, and 2 months. There was no statistically significant difference in the anterior chamber depth on postoperative day 1, 1 month, and 2 months. There was a statistically significant difference in the refraction on postoperative day 1 (p = 0.03). However, there was no statistically significant difference on postoperative 1 month (p = 0.07) and 2 months (p = 0.07). CONCLUSIONS: There was no statistically significant difference in the decentration, anterior chamber depth, and refraction between the 3-piece and single-piece aspheric IOL. Therefore, there is no difference between the 3-piece and single-piece aspheric IOL in the capsular bag stability until 2 months postoperatively.
