Abstract Details


To determine the refractive results, and contrast sensitivity after implantation of multifocal intraocular IOL TECNIS Symfony (ZXR00)


COI Bilbao Berri. Bilbao, Vizcaya. SPAIN


16 TECNIS Symfony ZXR00 IOLs were implanted in 10 patients of mean age 69 years (56-81) after lens extraction. SRK/T formula with a 119.3 A-constant was used for IOL power calculation. The refractive outcome was assessed, the VA at different distances was measured by hopping blur 0.50D and plotted in a defocus curve. Contrast sensitivity (CS) was tested by Sine Wave Contrast Test (SWCT, Visumetrics 1992) in mesopic conditions


The spheroequivalent residual refraction was -0.01 (-0.50 - +0.75). The mean logMAR VA in for close focus (-3.00D) was 0.56 ± 0.18; at intermediate focus (-1.50D) 0.11 ± 0.10 and far focus (+ 0.00D) 0.02 ± 0.07. The mean CS for different spatial frequencies was for A: 5.85 ± 0.66; B: 5.86 ± 0.66; C: 4.64 ± 0.84; D, 3.57 ± 1.10; E: 3.14 ± 1.35


Extended lens range vision TECNIS Symfony has a good refractive outcome with that provided constant, provides excellent distance and intermediate visual acuity with good contrast sensitivity at all frequencies.
