    Refractive Outcome Comparison Between Vitreomacular Interface Disorders After Phacovitrectomy
    (2017) Ercan, Zeynep Eylul; Akkoyun, Imren; Pinarci, Eylem Yaman; Yilmaz, Gursel; Topcu, Hulya; https://orcid.org/0000-0002-2860-7424; https://orcid.org/0000-0002-2589-7294; https://orcid.org/0000-0002-5259-0204; 10.1016/j.jcrs.2017.06.034; AAK-7713-2021; AAK-6987-2021
    Purpose: To compare the refractive accuracy of intraocular lens (IOL) power calculations between patients with vitreomacular interface disorders who had phacovitrectomy for vitreomacular traction (VMT), epiretinal membranes (ERM), and macular holes. Setting: Baskent University Department of Ophthalmology, Ankara, Turkey. Design: Retrospective case series. Methods: Refraction results 8 weeks postoperatively were compared between phacovitrectomy (3 study groups comprising eyes with VMT with intrafoveal pseudocysts, ERM, or medium-to-large macular holes) and phacoemulsification (control group comprising eyes having phacoemulsification only). The IOLMaster 700 partial coherence interferometry (PCI) device and Haigis formula were used for all calculations. Results: This study included 100 eyes (100 patients), 25 in each of the 4 groups. There was no statistically significant difference in axial length (AL) between the groups (P = .305). Differences in the pre-operative macular thickness were statistically significant between all groups except between the macular hole and VMT groups. Most eyes (92%) in the VMT and macular hole groups and all eyes in the VMT and phacoemulsification groups achieved a final refraction within +/- 1.00 diopter of the refractive aim. The mean prediction error and the mean absolute error did not differ significantly between the groups. In all groups, there was no significant correlation between prediction error and age, AL, preoperative refractive error, or preoperative or postoperative macular thickness (P > .05). Conclusions: The IOL power calculation with PCI yielded no difference in postoperative refraction errors between the vitreomacular interface disorders. There was no correlation with preoperative refraction, age, or preoperative or postoperative macular thickness. (c) 2017 ASCRS and ESCRS

    Evaluation of quality of life after implantation of a new trifocal intraocular lens
    (2019) Akman, Ahmet; Asena, Leyla; Ozturk, Caner; Gungor, Sirel Gur; 0000-0001-6178-8362; 0000-0002-6848-203X; 30612749; E-5914-2016; AAD-5967-2021
    Purpose: To evaluate the vision-related quality of life (QOL) after implantation of a new trifocal intraocular lens (IOL), by using the National Eye Institute Visual Function Questionnaire-14 (VF-14 QOL questionnaire). Setting: Baskent University Faculty of Medicine, Department of Ophthalmology, Ankara, Turkey. Design: Prospective noncomparative case series. Methods: Consecutive patients who had a new trifocal IOL (Pan-Optix) bilaterally implanted were included in the study. The vision-related QOL was assessed 3 months after the surgery in the second eye. The VF-14 QOL questionnaire was used, with a grading scale of 0, no difficulty; 1, a little difficulty; 2, moderate difficulty; 3, quite difficult; 4, impossible to perform. A subgroup of 14 patients, with an interval of at least 3 months between the surgery in the first eye and the surgery in the fellow eye, were also interviewed 3 months after the monocular IOL implantation. In this subgroup, the QOL with monocular and binocular implantation was compared. Results: The study comprised 48 patients. Reading small print, driving at night, and doing fine handwork were the most difficult tasks to perform, with the mean values of the VF-14 QOL questionnaire being 0.94 +/- 0.81 (SD), 0.89 +/- 0.68, and 0.64 +/- 0.67, respectively. Binocular implantation was associated with improvement in vision-related QOL when compared with monocular implantation, with significant differences in doing fine handwork such as sewing (P = .02) and using a computer (P = .03). Conclusions: With mean values of 1.00 or lower for each question, the results of the VF-14 QOL questionnaire indicated that patients who have the new trifocal IOL bilaterally implanted have an overall high satisfaction rate and a high vision-related QOL.
