Comparison between bilateral implantation of a trifocal intraocular lens (Alcon Acrysof IQ® PanOptix) and extended depth of focus lens (Tecnis® Symfony® ZXR00 lens).

Purpose: To compare the visual performance outcomes following bilateral cataract surgery using trifocal intraocular lens (Alcon Acrysof IQ® PanOptix) and extended depth of focus lens (Tecnis® Symfony® ZXR00 lens).

Methods: In this prospective, non-randomized, comparative trial, a total of 40 subjects (80 eyes) were divided into two different groups and submitted to bilateral cataract surgery and implantation of the two different IOLs, Alcon Acrysof IQ® PanOptix® TNFT00 in group A and Tecnis® Symfony® ZXR00 lens (Johnson & Johnson Vision) in group B, was assessed. The uncorrected and corrected near (33 cm), intermediate (60 cm), and far (4 m) binocular visual acuity was measured, and visual binocular defocus curves were also measured in the photopic condition with a long-distance visual acuity and the qualitative visual function was assessed by NEI VFQ-25.

The Argus-II Retinal Prosthesis Implantation; From the Global to Local Successful Experience.

Over the past few years, visual prostheses (namely, Argus II retinal implant) and gene therapy have obtained FDA approval in treating blindness resulting from retinitis pigmentosa. Compared to gene therapy; Argus II is less costly with a demonstrated favorable outcome, though the vision is yet artificial. To obtain better results, expectation counseling and preoperative retinal assessment are critical.

Intravitreal Injection of Bevacizumab: Review of our previous Experience.

Several ocular and systemic complications have been reported after the bevacizumab intravitreal injection. This study aims at reporting the main indications for the bevacizumab intravitreal injection in our center, the intravitreal injection method in this study, and the incidence of the post-injection complication, such as endophthalmitis.This study is a retrospective review of the consecutive intravitreal bevacizumab (Avastin®) injections for 359 patients between 2011 and 2013 at a single institute (Poostchi Clinic of Ophthalmology).

Pneumatic retinopexy for primary repair of rhegmatogenous retinal detachments.

Purpose: To evaluate anatomical and functional outcomes of pneumatic retinopexy (PR) for primary repair of rhegmatogenous retinal detachments and to determine demographic and ocular risk factors for failure of the procedure.

Design: Retrospective interventional case series.

Methods: A chart review on 97 eyes of 97 consecutive patients who had undergone PR as the initial procedure for unilateral recent primary retinal detachments with causative break(s) in the superior two-third of the retina.

Levodopa-carbidopa may improve vision loss in indirect traumatic optic neuropathy.

To compare the effect of levodopa-carbidopa on the visual outcome of patients with indirect traumatic optic neuropathy (ITON), this randomized, double-blind, placebo-controlled study was conducted on 32 patients with ITON within 6 days after trauma. Patients underwent a complete ocular examination, pattern visual evoked potential (PVEP) testing, and high-resolution orbital computed tomography (CT) scanning. All patients received high-dose intravenous methylprednisolone, and levodopa was also administered to the levodopa group.

Combined phacoemulsification and viscogoniosynechialysis in the management of patients with chronic angle closure glaucoma.

The purpose of this study was to evaluate the effectiveness of phacoemulsification and viscogoniosynechialysis in the management of patients with chronic angle-closure glaucoma (CACG). Fifty-six eyes of 45 recruited patients were classified into two groups: group 1 had medically controlled CACG (IOP 21 mmHg with maximum tolerated medications) including 21 eyes. All of the patients had at least one quadrant without peripheral anterior synechia in gonioscopy.

Brown syndrome in one pair of dizygotic twins: a case report.

Introduction: Brown syndrome is a rare ocular movement abnormality. This syndrome is characterized by an inability to elevate the affected eye in adduction. Most cases are sporadic but the occurrence in Monozygotic twins has suggested the possible autosomal dominant inheritance in Brown syndrome.

Preliminary results of subconjunctival bevacizumab in primary pterygium excision.

Purpose: To evaluate the efficacy of subconjunctival bevacizumab as an adjunctive therapy for primary pterygium surgery.

Material And Methods: This randomized prospective clinical study was conducted on 30 eyes of 30 patients. After pterygium excision and accomplishing a rotational conjunctival flap, 15 patients (case group) received 1.

Effect of anterior chamber air bubble on prevention of experimental Staphylococcus epidermidis endophthalmitis.

Background: Bacterial endophthalmitis is a serious complication of penetrating ocular trauma and cataract surgery. The purpose of this study is to assess the ability of an anterior chamber air bubble to prevent experimental Staphylococcus epidermidis endophthalmitis.

Methods: The anterior chamber was opened with a clear corneal incision to drain the aqueous humor in one eye of 24 rabbits.

Association of TNFA -308 G/A and TNFRI +36 A/G gene polymorphisms with glaucoma.

Objective: TNF-alpha is one of the most important factors recognized in the pathogenesis of open-angle glaucoma. Therefore, the association of single nucleotide polymorphisms in the TNFRI gene and the promoter region of the TNFA gene with glaucoma susceptibility was investigated in the present study.

Method: In total, 223 patients with glaucoma and 202 unrelated controls were genotyped by allele-specific oligonucleotide PCR and PCR- restriction fragment length polymorphism to determine TNFA -308 G/A and TNFRI +36 A/G polymorphisms, respectively.
