Abstract
Purpose :
To compare objective results after bilateral implantation of 4 different diffractive trifocal intraocular lenses (IOL) in a Mexican population.
Methods :
Prospective, interventional case series involving 31 cataract surgery patients who underwent bilateral implantation of the trifocal Micro F lens FineVision IOL (PhysIOL, Liège, Belgium), AcrySof IQ PanOptix IOL (Alcon, ), AT Lisa tri839 IOL (Zeiss, ) and Tecnis Symfony IOL (Abbot, ). Objective analysis involved assessment of monocular uncorrected distance (UDVA), near (UNVA) at 30 cm, and intermediate visual acuity (UIVA) at 70 cm, preoperatively and at postoperative months 1, 3 and 6. Higher order aberrations were assessed via aberrometry. Contrast sensitivity was determined via modulation transfer function (MTF). Subjective outcomes were assessed using the National Eye Institute Visual Functioning Questionnaire-25 (VFQ-25).
Inclusion criteria:
Men and women over 50 years old with bilateral cataract looking for spectacle independence, who underwent uncomplicated bilateral cataract surgery.
Exclusion criteria:
Any comorbilities or corneal cylinder over 1.00 D.
Results :
At postoperative 6 months, mean monocular UDVA for FineVision (PhysIOL) was 0.06±0.11 logMAR, UIVA was 0.04±0.08 logMAR, UNVA was 0.03±0.04 logMAR; For AT Lisa tri839 IOL, UDVA was 0.16±0.11, UIVA 0.32±0.11, UNVA 0.11±0.03; for AcrySof IQ PanOptix IOL UDVA -0.05±0.07, UIVA -0.01±0.03, UNVA -0.01±0.09; Symfony IOL UDVA -0.2±0.8, UIVA 0.00±0.11, UNVA 0.00±0.11. Spherical equivalent at postoperative month 3 was 0.23±0.4 diopters (D). VFQ-25 questionnaire results showed a mean score of 93.64 ± 4.19 points (maximum 100 points). Vision during distance and near activities were reported as ‘excellent’. Adverse events were reported as occurring ‘never to occasionally’. The worst UDVA was AT Lisa tri839 with a P value 0.029; the best UIVA was FineVision P= 0.00; the best UNVA was FineVision P= 0.00.
Conclusions :
Implantation of a diffractive trifocal IOL in a Mexican population appears safe and effective, both objectively and subjectively. Good uncorrected visual acuity outcomes were achieved at far, near and intermediate distances. Overall patient satisfaction was excellent.
