The aim of the present study was to evaluate the stability of four different types of aspheric intraocular lenses (IOLs) after implantation.
This retrospective study included 124 eyes implanted with four different types of aspheric IOLs including a one-piece four-loop fixed hydrophilic acrylic IOL, a one-piece flat fixed acrylic IOL, a one-piece two-loop fixed acrylic IOL, and a three-piece two-loop fixed silicone IOL. IOL decentration, tilt, and ocular coma-like aberration (coma) at one-week, one-month, three-month, and one-year time points were evaluated postoperatively.
IOL decentration, tilt, and coma in the AO, 36A, IQ, and KS-AiN implantation groups were statistically significantly different one week and one year postoperatively ( < 0.01). There were significant differences between each of the pairs of groups ( < 0.01), except for coma between the AO and 36A implantation groups one week postoperatively ( > 0.05). When comparing the different time points (ie, one week, one month, three months, and one year postoperatively), IOL decentration, tilt, and coma were significantly different in each group ( < 0.05). IOL decentration, tilt, and coma in each group increased over the period from one week to one year postoperatively. A positive linear correlation was observed between IOL decentration or tilt and coma one year postoperatively ( < 0.01).
One-piece multi-point fixed acrylic IOLs demonstrate better stability when compared with three-piece two-point fixed silicone IOLs. IOL decentration, tilt, and coma increase gradually over time. Ocular coma-like aberrations are influenced by the stability of IOLs.
本研究旨在评估四种不同类型的非球面人工晶状体（IOL）植入后的稳定性。
这项回顾性研究纳入了124只眼，这些眼植入了四种不同类型的非球面IOL，包括一片式四环固定亲水性丙烯酸酯IOL、一片式平面固定丙烯酸酯IOL、一片式双环固定丙烯酸酯IOL和三片式双环固定硅酮IOL。术后在一周、一个月、三个月和一年的时间点评估IOL的偏心、倾斜和类似眼彗差（彗差）情况。
AO、36A、IQ和KS - AiN植入组的IOL偏心、倾斜和彗差在术后一周和一年时有统计学显著差异（P<0.01）。除了术后一周AO和36A植入组之间的彗差（P>0.05）外，各植入组之间均有显著差异（P<0.01）。比较不同时间点（即术后一周、一个月、三个月和一年）时，每组的IOL偏心、倾斜和彗差均有显著差异（P<0.05）。每组的IOL偏心、倾斜和彗差在术后一周到一年期间均增加。术后一年时，IOL偏心或倾斜与彗差之间呈正线性相关（P<0.01）。
与三片式双点固定硅酮IOL相比，一片式多点固定丙烯酸酯IOL表现出更好的稳定性。IOL的偏心、倾斜和彗差随时间逐渐增加。类似眼彗差受IOL稳定性的影响。
