•Cataract removal and intraocular implantation affect the optical coherence tomography image quality assessments.•This is the first study to compare the image quality values of monofocal / trifocal intraocular lens in both macular and peripapillary optical coherence tomography scans.•Intraocular lens implantation seems to decrease the image quality of optical coherence tomography scanning compared to healthy unoperated eyes.•Despite significant differences in specially designed sinusoidal trifocal lenses, optical coherence tomography quality assessments has shown similar results to a monofocal lens. To evaluate the influence of trifocal and monofocal intraocular lens implantation on the optical coherence tomography-signal strength index values obtained during macular and peripapillary scanning. Study group included 60 eyes of 60 patients with intraocular lens (Acriva BB UD 613 monofocal in 30 eyes and Acriva Trinova UD trifocal in 30 eyes) implantation after uneventful phacoemulsification. Thirty eyes of 30 healthy subjects without any intraocular surgery were selected as the control group. Eyes with best corrected visual acuity less than 20/20 due to any media opacity, high refractive errors excluded. Macular and retinal nerve fiber layer scans were generated by optical coherence tomography after pupillary dilation. Intergroup comparisons of signal strength index values of the macular and peripapillary scans were performed between eyes implanted with two different intraocular lenses and control group. The mean signal strength index of the peripapillary and macular scans obtained in the eyes implanted with both monofocal and trifocal intraocular lenses were statistically less than the control group (p < 0.05, for all). SSI's of macular and peripapillary scans recorded from the eyes implanted with either monofocal or trifocal intraocular lenses were not statistically different from each other (p = 0.957 and p = 0.877, respectively). In the present study despite different intraocular lenses properties, the image quality values were not found to be lower in eyes with trifocal sinusoidal intraocular lenses implantation compared to monofocal intraocular lenses during macular and peripapillary optical coherence tomography scans.
