UNLABELLED: In recent years, a new class of extended depth of focus (EDOF) intraocular lenses (IOLs) has become available on the market. There is only a limited number of scientific papers comparing trifocal and EDOF IOL data, and the results are often contradictory.
PURPOSE: Comparative analysis of the results of trifocal and EDOF IOL implantation in patients with presbyopia and/or cataract.
MATERIAL AND METHODS: This prospective study included 72 patients (144 eyes) after bilateral implantation of either Tecnis Symfony EDOF IOL (18 patients, 36 eyes; group I) or AcrySof PanOptix trifocal IOL (54 patients, 108 eyes; group II). In 18 patients out of 72 (25%) the implantation involved mini-monovision, i.e. the calculation of the IOL power on the nondominant eye was performed at -0.5 D. The average follow-up period for the patients was 7.1±1.2 months.
RESULTS: There was a significant (p<0.05) increase in uncorrected near visual acuity (UCNVA), uncorrected intermediate visual acuity (UCIVA) and uncorrected distance visual acuity (UCDVA) at the maximum follow-up time compared to the preoperative indices in all groups. Group II was characterized by slightly better UCNVA dynamics (0.85±0.13 versus 0.2±0.04 before surgery, as comparted to 0.78±0.11 versus 0.19±0.06 before surgery in group I), but differences were not statistically significant (p>0.05). Statistically significant differences (p=0.046) were observed when comparing best corrected near vision acuity (BCNVA) in groups I and II (0.79±0.05 and 0.98±0.08, respectively) at 6 months compared to the preoperative period (0.62±0.09 and 0.6±0.11, respectively).
CONCLUSION: Trifocal IOL implantation was associated with acceptable near and far vision correction and a higher frequency of adverse optical phenomena, while implantation of the EDOF IOL was associated with slightly better correction of intermediate vision and a significantly lower incidence of halo and glare. Patients were satisfied with the outcomes of surgery in all cases.
