영문 초록

Purpose: To compare the decentration, tilt and anterior chamber depth between aspheric AcrySof^{Ⓡ IQ IOL (SN60WF) and spheric AcrySofⓇ Natural IOL (SN60AT). Methods: The subjects of this study consisted of 22 patients (26 eyes) using an aspheric AcrySofⓇ IQ IOL and 26 patients (31 eyes) using spheric AcrySofⓇ Natural IOL. All lenses were inserted into the capsular bag after 5 mm continuous curvilinear capsulorhexis and phacoemulsification. The decentration, tilt and anterior chamber depth of both IOLs were measured on the 1st, 30th and 60th postoperative day using an anterior eye segment analysis system (Scheimpflug camera, EAS-1000, Nidek, Japan). Results: There was no statistically significant difference in the decentration between the IQ IOL and Natural IOL on the 1st (p=0.05), 30th (p=0.09) and 60th (p=0.06) postoperative day. There was a statistically significant difference in tilt between IQ IOL and Natural IOL on the 1st (p=0.000053) and 30th (p=0.018) postoperative day. However, there was no statistically significant difference in tilt on the 60th postoperative day (p=0.05). The anterior chamber depth of IQ IOL was decreased, but was not statistically significant on the 1st (p=0.10), 30th (p=0.07) or 60th (p=0.06) postoperative day. Conclusions: There were no significant differences between AcrySofⓇ IQ IOL and AcrySofⓇ Natural IOL in decentration, tilt or anterior chamber depth, showing that posterior aspheric surface causes little effect on the IOL stability.}
