Abstract
Aim To compare the effects of previously implanted monofocal and multifocal intraocular lenses (IOL) on macular surgery. Methods Seventy eyes of 70 patients with epiretinal membrane (ERM) and symptomatic vitromacular traction syndrome that previously had IOL implantation for cataract surgery were included in this prospective randomized clinical trial. Cases were divided into two groups. Group 1 and Group 2 were composed of eyes with monofocal and multifocal IOLs, respectively. The effects of refraction error and IOL decentration at the time of macular surgery performed for ERM and ILM peeling, according to the lens type, were investigated. Pars plana vitrectomy (PPV) was performed to peel ERM and ILM in all cases. Complete ophthalmological examination, fundus fluorescein angiography, and optical coherence tomography imaging were made to all cases, preoperatively and postoperatively. Results The mean BCVA in Group 1 and Group 2 improved from 0.69 ± 0.15 and 0.38 ± 0.14 logMAR to 0.40 ± 0.14 and 0.10 ± 0.04 logMAR, respectively, at the 6th month. There was no statistically significant difference between the groups in terms of the mean spherical refraction error (P > 0.05) and IOL decentration level (P > 0.05). The mean time required for macular surgery in Group 2 was statistically significantly longer than that for Group 1 (P < 0.05). There was no statistically significant relationship between IOL decentration and macular surgery time in Group 1 (P > 0.05), but there it was found in Group 2 (P < 0.05). In Group 2, there was a positive correlation between IOL decentration and macular surgery time. Conclusion In cases with multifocal IOL implants, especially with lens decentration, the time of macular surgery for ERM and ILM peeling during PPV is longer than that of eyes with monofocal IOL due to fluctuations in the clarity of the surgeon's view.

Results. e mean BCVA in Group 1 and Group 2 improved from 0.69 ± 0.15 and 0.38 ± 0.14 logMAR to 0.40 ± 0.14 and 0.10 ± 0.04 logMAR, respectively, at the 6th month. ere was no statistically significant difference between the groups in terms of the mean spherical refraction error (P > 0.05) and intraocular lenses (IOL) decentration level (P > 0.05). e mean time required for macular surgery in Group 2 was statistically significantly longer than that for Group 1 (P < 0.05). ere was no statistically significant relationship between IOL decentration and macular surgery time in Group 1 (P > 0.05), but there it was found in Group 2 (P < 0.05)
Contraindicated situations associated with artificial lens may Journal of Ophthalmology develop after multifocal IOL implantation. In this randomized and controlled study, we aimed to investigate the effect of preimplanted monofocal or multifocal IOLs on macular surgery time
E mean spherical refraction error was 0.56 ± 0.26 diopters in Group 1 and 0.52 ± 0.27 diopters in Group 2. e mean IOL decentration in Group 1 and Group 2 was 1.07 ± 1.23 mm and 0.93 ± 1.22 mm, respectively. ere was no statistically significant difference between the groups in terms of the mean spherical refraction error (P > 0.05) and IOL decentration level (P > 0.055) (Figure 1). e mean time required for macular surgery in Group 2 was statistically significantly longer than Group 1 (P < 0.05) (Table 3) (Figure 2). e most important condition associated with prolongation of macular surgery was the level of decentration in multifocal IOL
Summary
In this randomized and controlled study, we aimed to investigate the effect of preimplanted monofocal or multifocal IOLs on macular surgery time
