Evaluation and Comparison of Contrast Sensitivity in Patients with Zaraccom Ultraflex or F260 Intraocular Lens Inserted

Purpose: In this study, we evaluated the optic performance of Zaraccom UF intraocular lens (IOL) by comparing the contrast sensitivity of IOLs in photopic and mesopic lighting conditions in patients who were operated for cataract and inserted Zaraccom Ultraflex (UF) or Zaraccom F260 (F260) IOL.

Methods: In this prospective study, we included 60 eyes of 60 patients (Group 1: 30 patients UF, Group 2: 30 patients F260) who had undergone phacoemulsification with implantation of IOL in the posterior chamber between 2009 and 2010 in Ophthalmology Department at Cumhuriyet University. The patients were examined routinely at the 1. day, 1. week and 1. month postoperatively. At the third month, the best-corrected visual acuity values were recorded; then,, the contrast sensitivity tests at 1.5, 3, 6, 12 and 18 cpd were examined in all patients in all frequencies in photopic (with and without glare) and mesopic (with and without glare) lighting conditions. Results: When comparing the contrast sensitivity results in the two groups, we found that UF group’s values were higher in all spatial frequencies (1.5, 3, 6, 12 and 18 cpd). The results were statistically significantly greater for the test frequencies of mesopic without glare 1.5 (p=0.016) and 18 (p=0.005) cpd, mesopic with glare 6 (p=0.002) cpd, photopic without glare 1.5 (p=0.01), 3 (p=0.04), 6 (p=0.001) and 12 (p=0.001) cpd, photopic with glare 6 (p=0.01) and 12 (p=0.02) cpd (p<0.05). Conclusion: These results show that both IOLs provide good level of contrast sensitivity, but better visual perception is achieved with UF IOL. We think that the High Modulation Transfer Function (MTF) value of the UF IOL is an important factor for the obtained results.
