Purpose The aim of this study was to evaluate the refractive outcomes following cataract surgery using single‐piece and three‐piece monofocal intraocular lenses (IOLs). Methods In this retrospective study 114 eyes were enrolled. Monofocal single‐piece IOLs were used in group I (Quatrix/Croma., Austria, 61 eyes) and group II (Acrysof IQ /Alcon Laboratories Inc., Texas, 29 eyes) while three‐piece IOLs were implanted in group III (Mediconsult A85UV/Mediconsult Intraocular., Germany, 24 eyes). The main clinical outcome parameter evaluated was the remaining spherical equivalent refraction (Remaining SER: post‐op SER – target refraction). Kruskal‐Wallis non‐parametric ANOVA statistic test was used for data analysis. Results The mean target refraction was ‐0.52D (SD 0.34). The mean remaining SER in group I, [Iota][Iota] and III was +0.46D (SD 0.93), +0.25D (SD 0.61) and ‐0.29D (SD 0.97) respectively. Kruskal‐Wallis H test showed that there was a statistically significant difference in the residual refractive error among the different IOL implants (H (2) =11.255, P=.004). Conclusion According to statistics, single‐piece IOL implants Quatrix and AcrySof IQ induced a slight hyperopic shift whereas the refractive outcomes of three‐piece implants (Mediconsult A85UV) concurred with the preoperative target. Future prospective studies and a larger number of cases are needed to verify the aforementioned results.
