RESUMO
OBJECTIVES: To assess the visual outcomes in patients who underwent cataract surgery with multifocal intraocular lens (IOL) implantation using a "mix and match" approach. MATERIALS AND METHODS: Twenty patients (40 eyes) were involved in this prospective, nonrandomized study. Refractive multifocal IOLs (ReZoom NXG1) were implanted in patients' dominant eyes and diffractive multifocal IOLs (Tecnis ZMA00) were implanted in their non-dominant eyes. Monocular and binocular uncorrected distance, intermediate and near visual acuity (logMAR), and contrast sensitivity levels were measured at 1, 3, and 6 months after cataract surgery. Defocus curves, reading speeds, patient satisfaction, spectacle dependence, and halo and glare symptoms were also evaluated at 6 months after the surgery. Postoperative quality of life was assessed with the Turkish version of National Eye Institute Visual Function Questionnaire-25. RESULTS: The study group comprised 8 females and 12 males with a mean age of 69.45±10.76 years (range, 31-86 years). The uncorrected distance and intermediate visual acuity levels were significantly better in the ReZoom-implanted eyes at postoperative 6 months (p=0.026 and p=0.037, respectively). There was no statistically significant difference in uncorrected near visual acuity (p>0.05). There was no statistically significant difference in contrast sensitivity, reading speed, halos, or glare between the groups (p<0.05). Mild glare/halo was reported by 40% of the subjects. The mean patient satisfaction was 95% and all patients were spectacle independent. CONCLUSION: Mixing and matching multifocal IOLs in selected cataract patients provides excellent visual outcome, a high level of patient satisfaction, and spectacle independency.
RESUMO
AIM: To compare the effectiveness of photodynamic therapy (PDT) and PDT combined with intravitreal triamcinolone (IVTA) and vascular endothelial growth factor inhibition (anti-VEGF) in age-related macular degeneration (AMD). MATERIALS AND METHODS: Eighty eyes of 80 patients diagnosed with choroidal neovascularization (CNV) caused by AMD were included in the study. PDT was carried out on 40 eyes in group I, and PDT combined with 4 mg IVTA and anti-VEGF (1.25 mg bevacizumab in 20 eyes, 0.3 mg pegaptanib sodium in 20 eyes) was carried out in group II. The primary efficacy endpoint was the mean change from baseline visual acuity at month 12. RESULTS: Mean follow-up was 14.2 ± 2.18 months in group I and 12.45 ± 2.82 months in group II. In group I there was a 2.88 logMAR line decrease and 1.95 logMAR line increase in group II in vision between pretreatment and 12th month measurements (P < 0.05). Mean PDT session was 2.00 in group I and the mean combined treatment session was 1.15 in group II in the 12th month. CONCLUSION: Combination of IVTA and anti-VEGF with PDT is more effective and safer than PDT monotherapy in the treatment of CNV secondary to AMD. Combination treatment decreases the frequency and number of treatment sessions for an improved visual prognosis.
