Purpose:
Optical properties of commonly used multifocal and extended-depth-of-focus (EDOF) intraocular lenses (IOLs) can induce artifacts or changes in optical coherence tomography (OCT) measurements. Our purpose was to investigate the possible effects of different IOLs on peripapillary and macular OCT parameters.
Methods:
The preoperative and postoperative third-month peripapillary OCT and ganglion cell analysis (GCA) parameters of patients having monofocal (Alcon IQ), multifocal (PanOptix), or EDOF (Vivity) IOL implanted during cataract surgery were compared.
Results:
Sixty-four eyes of 64 patients were included (21 monofocal, 24 multifocal, and 19 EDOF). Although all OCT image qualities increased postoperatively, only GCA image quality changes in the monofocal and multifocal groups reached statistical significance. Most peripapillary retinal nerve fiber layer (RNFL) and GCA parameters were similar preoperatively and postoperatively. The superior RNFL thickness in the monofocal group and the temporal RNFL thickness in the EDOF group were higher postoperatively ( P = 0.04 and P = 0.02, respectively). Most GCA and RNFL value changes between preoperative and postoperative measurements were similar between groups. In the parameters that changed, postoperative values were higher in the monofocal group ( P = 0.02 for minimum ganglion cell layer and inner plexiform layer, P = 0.04 for average RNFL).
Conclusion:
Trifocal and EDOF IOLs do not seem to have a negative effect on OCT parameters.
