BACKGROUND: The aim of this study was to evaluate the surgical handling and clinical applicability of a specific 3D-printed membrane design fabricated using a gelatin, elastin and sodium hyaluronate blend for conjunctival reconstruction and compare it with amniotic membrane (AM), which is normally used in such surgeries. METHODS: 3D printing technique was employed to fabricate the membrane based on gradient design. Prior to printing, rheometry was employed to optimize the ink composition...

PURPOSE: To compare 18-month outcomes between femtosecond laser-assisted LASIK (femto-LASIK) and photorefractive keratectomy with mitomycin-C (PRK-MMC) for myopia of more than 7.0 D in terms of visual acuity and quality. METHODS: In this comparative nonrandomized clinical trial, 60 eyes from 30 patients (30 eyes in each group) were enrolled. The two procedures were compared in terms of 18-month changes in uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction spherical equivalent, ocular and corneal higher order aberrations (HOAs), and contrast sensitivity (CS)...

OBJECTIVE: To compare the effect of femtosecond-assisted thin flap laser-assisted in situ keratomileusis (FS-LASIK) and photorefractive keratectomy with mitomycin-C (PRK-MMC) in highly myopic patients (>7.0 D [D]) on corneal biomechanical parameters. METHODS: In this prospective comparative interventional case series, 60 patients (30 patients in each group) with a manifest refractive spherical equivalent (MRSE) greater than 7.0 D were enrolled. Corvis ST parameters were measured before and at 3 and 6 months postoperatively...

OBJECTIVE: To compare the results of femtosecond-assisted laser in situ keratomileusis (femto-LASIK) and photorefractive keratectomy with mitomycin C (PRK-MMC) for the correction of myopia more than 7.0 diopters (D). METHODS: In this comparative nonrandomized trial, 60 eyes (30 eyes in each group) were enrolled. Patients were tested for uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction spherical equivalent, ocular and corneal aberrations, and contrast sensitivity (CS) before surgery and at 3 and 6 months postoperatively...

BACKGROUND: Catastrophic effects of mustard gas as a chemical warfare agent have always been a major problem for those exposed to this agent. In this meta-analysis it was tried to evaluate carcinogenesis, ocular, cutaneous and respiratory complications of mustard gas exposure among Iranians who had been exposed to this agent during the Iran-Iraq war. MATERIALS AND METHODS: In this meta-analysis, the required data were collected using keywords "mustard gas", "sulfur mustard", "cancer", "neoplasm", "respiratory complications", "ocular complications" , "lung disease", "chronic complication", "eye", "skin", "cutaneous complication", "carcinogenesis" and their combination with keywords "Iran", "Iranian", "prevalence", "mortality" and their Farsi equivalent terms from the databases of SID, Iranmedex, Magiran, Pubmed, Science Direct, Google Search engine, Gray Literature and Reference of References...

AIM: To evaluate the effect of implantation depth of Intacs microthin prescription inserts (Addition Technology Inc, Fremont, California) on visual and topographic outcomes in patients with post- laser-assisted in situ keratomileusis (LASIK) ectasias. SETTINGS AND DESIGN: Retrospective, observational case series. MATERIALS AND METHODS: In this case series, 16 eyes of 12 patients were evaluated. All cases were post-LASIK ectasia that had undergone intrastromal corneal ring segment (ICRS) implantation...

OBJECTIVE: To determine the normal reference range for phenol red thread test (PRTT) values in clinically normal Syrian hamsters (Mesocricetus auratus). ANIMALS: Sixteen healthy adult Syrian hamsters (eight males and eight females) were used in this study. PROCEDURE: Ophthalmic examinations were performed without chemical restraint. PRTT values were evaluated in both eyes of all Syrian hamsters using a commercial PRTT strip of a single lot number...

PURPOSE: To evaluate ocular biometric parameters in different subtypes of angle-closure disease in the Iranian population and compare them with normal eyes. DESIGN: Prospective, cross-sectional. METHODS: In this clinic-based study, 189 eyes of 154 patients consisting of 40 acute angle-closure glaucoma (AACG) eyes, 40 fellow eyes of AACG, 42 chronic angle-closure glaucoma (CACG) eyes, 40 primary angle-closure suspect (PACS) eyes, and 27 normal eyes underwent complete examination including gonioscopy, A-scan biometry, and anterior segment optical coherence tomography...

BACKGROUND: To compare the anatomic effects of phacoemulsification (Phaco) versus combined phacoemulsification and viscogonioplasty (Phaco-VGP) on drainage angle status in primary angle-closure glaucoma (PACG) using anterior segment optical coherence tomography (AS-OCT). DESIGN: Prospective, randomized clinical trial. PARTICIPANTS: Sixty-seven eyes of 57 patients with the diagnosis of PACG. METHOD: Patients were randomized to undergo Phaco alone (33 eyes) or Phaco-VGP (34 eyes)...

PURPOSE: To evaluate the results of a combined approach of cicatrix lysis, intraoperative mitomycin C (MMC) application, oral mucosal transplantation (OMT), and amniotic membrane transplantation (AMT) for surgery of severe symblepharon. METHODS: This prospective study included 32 eyes with severe symblepharon in which after cicatrix lysis the residual conjunctiva was not enough to cover the tarsus (grade III symblepharon) or there was no residual conjunctiva (grade IV symblepharon)...

Ataxia-telangiectasia is a multisystem disorder characterized by progressive neurologic impairment, variable immunodeficiency, impaired organ maturation, x-ray hypersensitivity, oculocutaneous telangiectasia, and a predisposition to malignancy. To evaluate clinical and immunologic features of Iranian patients with ataxia-telangiectasia, the records of 104 patients with ataxia-telangiectasia (54 male, 50 female) with the age range of 1.6-23.5 years were reviewed. The Iranian Primary Immunodeficiency Registry was used as the data source...

OBJECTIVE: The aim of this study was to assess the feasibility of a new technique to treat overfiltering blebs leading to hypotony after penetrating glaucoma surgery. BACKGROUND: There is no previous report on diode laser application with G-probe on ocular hypotony consequent to trabeculectomy with adjunctive mitomycin-C. METHODS: This clinical trial was conducted on eight eyes of eight patients with hypotony after trabeculectomy with adjunctive mitomycin-C...
