BACKGROUND To perform a microbiological contamination analysis of the vitreous during office-based micro-incision vitrectomy surgery (MIVS) assessing whether the bacteria detected correlated with patient's ocular conjunctival flora. METHODS This is a prospective, interventional, nonrandomized case series of patients undergoing office-based MIVS, anti-VEGF, and dexamethasone intravitreal injec...

METHODS: In this prospective randomized study, patients had standard coaxial (2.8 mm incisions), microcoaxial (2.2 mm incisions), or biaxial microincision (1.2 to 1.4 mm trapezoidal incisions) phacoemulsification. Intraoperative phaco parameters and total surgical time were measured and complications recorded. Postoperative visual acuity improvement, pachymetric differences, and surgically indu...

PURPOSE To compare the effects of biaxial microincision cataract surgery (B-MICS) and microcoaxial cataract surgery (C-MICS) techniques on corneal optical quality. MATERIALS AND METHODS In this prospective study, 40 eyes underwent B-MICS and 40 eyes C-MICS. Corneal aberrations were derived from conversion of the corneal elevation profile into corneal wavefront data with 6.0  mm aperture diame...

PURPOSE To predict the results of vitreous surgery in patients with proliferative diabetic retinopathy (PDR), the correlation between vitreous fluid levels of vascular endothelial growth factor (VEGF) or endostatin and the postoperative outcome was investigated. METHODS VEGF and endostatin levels in vitreous fluid specimens obtained during vitreous surgery were measured by enzyme-linked immun...

Purpose: To compare the outcomes of coaxial microincision phacoemulsification with that of conventional coaxial phacoemulsification SETTING: Department of Ophthalmology, Farabi and Noor Eye Hospitals, Tehran, Iran Methods: In a prospective study, 74 eyes of 74 patients with cataract were randomly selected to have cataract extraction using 1 of 2 techniques: coaxial microincision phacoemulsifica...

PURPOSE To analyze early corneal endothelial cell loss due to microincision cataract surgery (MICS) in comparison with standard phacoemulsification through the temporal clear corneal incision. METHODS The examined group consisted of a nonrandomized, consecutive prospective series of 20 eyes of 20 patients who underwent uneventful microincision cataract surgery. Twenty eyes of 20 patients who ...

BACKGROUND AND OBJECTIVE Vitrectomy markedly alters the intraocular milieu, which can then affect the physiology of the retina and choroid. This study investigates whether vitrectomy also alters ocular blood flow as determined by laser speckle flowgraphy (LSFG). PATIENTS AND METHODS Twenty eyes of 20 patients that underwent vitrectomy for idiopathic macular hole or epiretinal membrane were st...
