    Comparison of Visual Performance and Quality of Life with A New Nondiffractive EDOF Intraocular Lens and A Trifocal Intraocular Lens
    (2023) Asena, Leyla; Dogan, Irem Kirci; Oto, Sibel; Altinors, Dilek Dursun; 0000-0003-0171-4200; 0000-0002-6848-203X; 0000-0002-5574-7318; 36700928; AAJ-4668-2021; E-5914-2016
    Purpose: To compare visual performance and quality of life (QoL) following bilateral implantation of a new nondiffractive extended depth-of-focus (EDOF) intraocular lens (IOL) and a trifocal IOL. Setting: Department of Ophthalmology, Baskent University Faculty of Medicine, Ankara, Turkey. Design: Prospective comparative interventional case series. Methods: 104 eyes of 52 patients with cataract, bilaterally implanted with a nondiffractive EDOF IOL or a trifocal IOL, were included. Outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), distance corrected intermediate visual acuity and distance corrected near visual acuity, defocus curves, QoL (Visual Function Index 14), quality of vision (Quality of Vision [QoV] index), contrast sensitivity (Pelli-Robson chart), and binocular reading speed. Results: Twenty-six patients were included in each group. The UDVA and CDVA were better in the EDOF group (0.05 +/- 0.04 and 0.01 +/- 0.04) than the trifocal group (0.13 +/- 0.06 and 0.11 +/- 0.07) (P=.02 and .01). Defocus curves showed that visual acuity was better with the EDOF IOL for vergences at 0.00, -0.50, and -1.00 and better with the trifocal IOL for vergences at -2.50, -3.00, -3.50, and -4.00. Contrast sensitivity scores were similar with both IOLs (P=.12). The overall mean QoL scores were lower in the EDOF group, indicating a better QoL (P=.04). The QoV was better in the EDOF group with significantly less glare, halos, and blurry vision (P<.01). Conclusions: The EDOF IOL performed better at distance, and the trifocal IOL performed better at near. Overall QoL and quality of vision were better with the EDOF IOL.

    Investigation of relationship between colour discrimination ability and stereoscopic acuity using Farnsworth Munsell 100 hue test and stereo tests
    (2020) Koctekin, Belkis; Coban, Deniz Turgut; Ozen, Mehmet; Tekindal, Mustafa Agah; Unal, Ayse Cengiz; Altintas, Ayse Gul Kocak; Gundogan, Nimet Unay; 31712007
    Objective: To evaluate the effect of colour discrimination ability on the stereoscopic acuity by comparing individuals having congenital colour vision deficiency (CCVD) with healthy individuals. Design: A comparative study. Participants: The study included 53 binocular males, of whom 26 (mean age, 36.04 +/- 9.30 years) were in the healthy group and 27 (mean age, 33.04 +/- 9.81 years) were in the CCVD group. Methods: The following tests were used: the Ishihara pseudo-isochromatic plate test for detecting CCVD, the Farnsworth Munsell 100 (FM100) hue test for colour discrimination ability, the TNO and Titmus stereo tests for stereoscopic acuity. Results: In the CCVD group, 20 males were deutan and 7 males were protan. According to the FM100 hue test, total error score (TES), blue/yellow (b/y) local error score (LES), and red/green LES were significantly lower in the healthy group (30.23 +/- 18.78, 15.15 +/- 10.38, and 13.88 +/- 11.93, respectively) than in the CCVD group (133.59 +/- 67.45, 41.15 +/- 22.03, and 89.15 +/- 52.16, respectively) (p < 0.01 for each). The stereo test scores revealed significantly higher stereoscopic acuity in the healthy group (43.85 +/- 33.92 arcsec for the TNO test and 40.00 +/- 0.00 arcsec for the Titmus test) than in the CCVD group (93.33 +/- 90.51 arcsec for TNO stereo test and 52.96 +/- 24.62 arcsec for the Titmus test) (p < 0.05 for each). The TNO test score was significantly and positively correlated with the TES (r = 0.390, p = 0.049) and b/y LES (r = 0.490, p = 0.011) in the healthy group. Conclusions: Colour discrimination ability affected stereoscopic acuity. Moreover, stereoscopic acuity increased with increasing colour discrimination ability, which could be originated from the b/y colour region.
