Comparison of Clinical Outcomes and Patient Satisfaction Between Two Different Diffractive Trifocal IntraocularLenses Implantation: Prospective Clinical Trial

Objective: To compare the clinical outcomes and visual quality of subjects undergoing cataract surgery with the implantation of two different models of diffractive trifocal intraocular lenses (IOL). Material and Methods: This was a prospective, parallel-group, randomized, comparative, single-masked clinical study. A total of 30 subjects, who were scheduled to undergo bilateral cataract surgery were randomly assigned to two groups: RayOne and PanOptix IOL. The outcome measures were corrected and uncorrected distance visual acuity (CDVA, UDVA) at 4 m, uncorrected intermediate visual acuity (UIVA) at 80 and 60 cm, distance-corrected intermediate visual acuity (DCIVA) at 60 and 80 cm, distance-corrected and uncorrected near visual acuity at 40 cm, and patients' satisfaction. Results: Each group comprised 30 eyes of 15 subjects. No statistically significant differences were determined between the groups in terms of CDVA, UDVA, distance-corrected near visual acuity, and uncorrected near visual acuity. The monocular UIVA values at 80 cm were 0.09±0.09 logMAR in the RayOne IOL group and 0.19±0.11 logMAR in the PanOptix IOL group (p=0.01). The UIVA values at 60 cm were better in the PanOptix IOL group (p=0.049,p=0.01, respectively), and the DCIVA at 80 cm were better in the RayOne IOL group (p=0.01,0.047, respectively). The RayOne IOL group had more bothersome halos and starbursts (p=0.026,p=0.01, respectively). Conclusion: Both IOLs provided a very good restoration of visual acuity. However, with the PanOptix IOL, the likelihood of subjects experiencing bothersome halos and starbursts was less. The RayOne IOL might be a better choice for subjects that require further intermediate vision.
