Comparison of the optical behaviour of five different multifocal diffractive intraocular lenses in a model eye.

The purpose of this study was to investigate and compare the optical performance of five trifocal intraocular lenses (IOLs) following the ISO 11979-2 standards, analysing the impact of tilt and decentration. Five different diffractive trifocal IOLs were evaluated in this experimental study: Acriva Trinova (VSY-Biotechnology) (AT), FineVision HP (PhysIOL) (FVHP), AT LISA tri 839 MP (Zeiss) (ATLT), PanOptix TFNT00 IOL (Alcon) (PO), and Tecnis Synergy (J&J Vision) (TS). In-vitro optical quality analysis of them was performed with the Lambda PMTF system that has an aberration neutral cornea model (Lambda-X Ophthalmics).

Effect of the povidone iodine, hypertonic alkaline solution and saline nasal lavage on nasopharyngeal viral load in COVID-19.

Objective: The present study aimed to investigate the in vivo activity of nasal irrigation (NI) with saline, NI with povidone-iodine (PVP-I) 1%, NI with a mix of hypertonic alkaline and PVP-I 1% against Severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2).

Design: This study was a prospective randomised clinical trial.

Setting: A multicenter study involving tertiary care centres.

Validation and Clinical Application of the Turkish Version of the RhinoQOL Questionnaire in the Setting of Chronic Rhinosinusitis with Nasal Polyp Patients.

Objectives: Validation of the translations of questionnaires from foreign languages is important. Failure to validate surveys can lead to misapplication.

Methods: A total of 64 patients who presented with nasal obstruction due to chronic rhinosinusitis with nasal polyps and 64 control subjects were included in this prospective instrument validation study.

Cochlear Implant Complications in a Tertiary Referral Center in Istanbul.

Objective: All surgeons should inform the patients about complications and also their clinic's complication rates of cochlear implantation (CI). We aimed to review the complications of CI in 1,148 pediatric and adult patients.

Methods: It is a retrospective case review study enrolled in a tertiary referral center in Istanbul where CI was mostly performed.

Comparison of Pattern Electroretinography and Optical Coherence Tomography Parameters in Patients with Primary Open-Angle Glaucoma and Ocular Hypertension.

Objectives: To investigate the correlation of visual field (VF), pattern electroretinography (PERG) and Fourier domain optical coherence tomography (FD-OCT) results in patients with ocular hypertension (OHT) and early primary open-angle glaucoma (POAG).

Materials And Methods: The study included 72 eyes of 37 patients with early POAG, 76 eyes of 38 patients with OHT, and 60 eyes of 30 controls. All subjects underwent full ophthalmologic examination, VF assessment with 24-2 Humphrey standard automated perimetry (Swedish Interactive Thresholding Algorithm (SITA)-Standard), retinal nerve fiber layer (RNFL) and ganglion cell complex (GCC) thickness measurement with FD-OCT, and PERG P50 and N95 wave latency and amplitude measurements with electroretinography (Nihon Kohden).

Effectiveness of the lower eyelid suspension using fascia lata graft for the treatment of lagophthalmos due to facial paralysis.

Purpose: To evaluate of functional and cosmetic effectiveness of lower eyelid sling technique with fascia lata graft in patients with lagophthalmos due to facial paralysis.

Material And Method: Ten patients with a mean age of 55.1 ± 19.

Retinal nerve fiber layer thickness in women with polycystic ovary syndrome.

Aim. To compare the retinal nerve fiber layer (RNFL) thickness between women with polycystic ovary syndrome (PCOS) and healthy women. Materials and Methods.

Effect of Bevacizumab Injection before Vitrectomy on Intravitreal Hemorrhage in Pseudophakic Patients with Proliferative Diabetic Retinopathy.

We evaluated the effect of intravitreal bevacizumab (IVB) injection before pars plana vitrectomy (PPV) on intravitreal hemorrhage (VH) during and after vitrectomy for postoperative the first day and the first month in pseudophakic patients with proliferative diabetic retinopathy (PDR). This retrospective study was performed on 44 eyes of 44 patients who underwent vitrectomy for PDR. Patients were divided into PPV (n = 22 eyes) and PPV + IVB (n = 22 eyes) groups.

Central macular thickness in patients with type 2 diabetes mellitus without clinical retinopathy.

Background: An increase in macular thickness due to fluid accumulation in the macula in patients with diabetes mellitus. Optical coherence tomography (OCT) has been shown to be highly reproducible in measuring macular thickness in normal individuals and diabetic patients. OCT can detect subtle changes of macular thickness.

Effect of intracameral carbachol given during cataract surgery on macular thickness.

To evaluate the effect of intracameral carbachol on foveal thickness in patients who underwent uneventful cataract surgery. This retrospective study included two groups: the study group patients (group 1, n = 47 eyes) had uneventful cataract surgery and received only carbachol 0.01 % for miosis; the control group patients (group 2, n = 49 eyes) had uneventful cataract surgery without carbachol or any intracameral medication(s).

Foveal and parafoveal retinal thickness in healthy pregnant women in their last trimester.

Purpose: The inspection of foveal and parafoveal thickness in healthy pregnant women in the last trimester.

Materials And Methods: This study included 40 healthy pregnant women in their last trimester (study group: 40 women, 80 eyes) and 37 nonpregnant women (control group: 37 women, 74 eyes). Visual acuity, intraocular pressure, slit lamp examination of anterior and posterior segments, and visual field examination with automated perimetry were performed in both groups.
