Table 5 Cause analysis of heterogeneity
Study | Analysis | The reason for the heterogeneity |
|---|---|---|
Daniel.et al.2021(2) [16] | Comparative study of the BCVA between sutureless SF-IOL and suture SF-IOL | 10–0 polypropylene and 9–0 polypropylene were both used in this study |
Zhang.et al.2021 [21] | Comparative study of the BCVA between sutureless SF-IOL and suture SF-IOL | The specific types of sutures were not mentioned, and the scope of vitrectomy included anterior and total vitreous |
Yodpong.et al.2018 [22] | Comparative study ofthe Absolute Postoperative Spherical Equivalent between sutureless SF-IOL and suture SF-IOL | This study use a new technique which may lead the postoperative IOL-related astigmatism by induce the IOL tilt |
Jae.et al. 2020 [20] | Comparative study ofthe Absolute Postoperative Spherical Equivalent between sutureless SF-IOL and suture SF-IOL | The caliber of vitrectomy for Yamane technique was 25G and that of suture scleral IOL implantation was 23G |
Kyu.et al.2021 [18] | Comparative study ofthe postoperative IOL-related astigmatism between sutureless SF-IOL and suture SF-IOL | Remove the old IOL and insert a new IOL by a 2.75-mm corneal incision |
Yodpong.et al.2018 [22] | Comparative study ofthe postoperative IOL-related astigmatism between sutureless SF-IOL and suture SF-IOL | This study use a new technique which may lead the postoperative IOL-related astigmatism by induce the IOL tilt |
Yu. et al.2018 [23] | Comparative study ofthe intraocular pressure reduction between sutureless SF-IOL and suture SF-IOL | The suture fixation group had a larger incision and more operations than the non-suture fixation group in this study |
Jae.et al. 2020 [20] | Comparative study ofthe absolute postoperative spherical equivalent between Yamane technique and suture SF-IOL | The caliber of vitrectomy for Yamane technique was 25G and that of suture scleral IOL implantation was 23G |
Yodpong.et al. 2018 [22] | Comparative study ofthe absolute postoperative spherical equivalent between Gabor technique and suture SF-IOL | The forward movement of the optical part of the intraocular lens after the IOL haptic enters the scleral tunnel during IOL fixation |
