Subjective Perception Of Trifocal IOL Performance, Including Toric Models

Purpose: To study the patients' perception of trifocal IOL (Panoptix (TM)) performance. Patients and methods: 60 eyes of 35 were implanted with trifocal IOL. Refractive (sphere - S, cylinder - Cyl and spherical equivalent - SE, all in D) and visual (distance uncorrected - VAsc, distance corrected - VAcc, intermediate - IntVA, near uncorrected - NVAsc and distance corrected near - NVAcc, all in LogMAR) results were recorded. Patients were asked about satisfaction (per eye), spectacle independence, near and intermediate activities, distance activities in quantity and quality, finally about personal facial care (per patient). Comparison was made between nontoric (48) and toric models, genders (18 males) and between bilateral (25 patients) and unilateral implantations. Results were correlated to age and IOL power. Results: With a SE of mean -0.3 +/- 0.5 D, cases achieved mean VAsc 0.09 +/- 0.1 (similar to 20/25), VAcc 0.05 +/- 0.1 (similar to 20/22), IntVA 0.05 +/- 0.9 (similar to 20/22), NVAsc 0.05 +/- 0.09 (similar to 20/22) and NVAcc 0.04 +/- 0.8 (20/22). Mean level of satisfaction was 85.7 +/- 16.5, spectacle independence 96.0 +/- 10.6, near activities 95.4 +/- 9.8, intermediate activities 97.7 +/- 6.4, quantity of distance activities 90.2 +/- 10.1, quality of distance activities 88.0 +/- 12.1 and facial care 92.6 +/- 11.9. All comparisons (non-toric and toric, male and female and bilateral and unilateral implantation) were statistically insignificant (P>0.05). Correlation with age and IOL power was also statistically insignificant (P>0.05). Conclusion: As perceived by patients, trifocal IOL resulted in very high level of satisfaction. This satisfaction is reflected on diverse visual activities. This level is achieved regardless of gender, IOL model or even unilateral implantation. It is also achieved regardless the age of patients or preoperative eye status.
