Purpose: To evaluate the potential risk factors of posterior capsule opacification (PCO) after cataract surgery. Methods: Data on PCO patients diagnosed from September 2015 to May 2017 were obtained from the Department of Ophthalmology at Qingdao Municipal Hospital, Qingdao, China. The factors associated with PCO were assessed using Pearson's χ 2 test for univariate analyses and logistic regression for multivariate analyses. Results: Eyes (652) from 550 patients were enrolled in this study...

The aim of our present study is to evaluate the efficacy of pranoprofen eye drops as pain relief during sequential second-eye cataract surgery and to investigate the possible mechanism. Seventy-six patients scheduled for bilateral sequential cataract surgery were randomly assigned to two groups: (1) treatment group (administered pranoprofen eye drops), or (2) control group (administered artificial tears). Preoperative anxiety and intraoperative pain were assessed. Monocyte chemoattractant protein 1 (MCP-1) in the aqueous humor was measured with a suspension cytokine array...

Purpose: Cataract surgery is a procedure by which the lens fiber cell mass is removed from its capsular bag and replaced with a synthetic intraocular lens. Postoperatively, remnant lens epithelial cells can undergo an aberrant wound healing response characterized by an epithelial-to-mesenchymal transition (EMT), leading to posterior capsular opacification (PCO). Aldose reductase (AR) inhibition has been shown to decrease EMT markers in cell culture models. In this study, we aim to demonstrate that AR inhibition can attenuate induction of EMT markers in an in vivo model of cataract surgery...

BACKGROUND: Cataract surgery is associated with a variety of complications, one of which is vitreous loss. Doctors and policymakers should be aware about the precipitating factors, associations, and expected outcomes of vitreous loss. This study was, therefore, undertaken to set guidelines to improve the visual outcomes of patients. MATERIALS AND METHODS: A retrospective 8-year analysis was conducted from 2007 to 2014 using the national eye database. Demographic features, ocular comorbidities, grade of surgeon, type of surgery, and the associations with the occurrence of vitreous loss, and the final visual outcomes of these patients were studied...

Transforming growth factor‑β (TGF‑β) is important in the development of posterior capsule opacification (PCO), and inhibition of the TGF‑β pathway may represent a novel method of treating PCO. Drosophila protein, mothers against decapentaplegic homolog 3 (Smad3) is a phosphorylated receptor‑activated Smad required for the transmission of TGF‑β signals. Smad3 knockout (KO) disturbs the activation of TGF‑β signaling, thus inhibiting the onset of PCO. In the present study, lens epithelial cell (LEC) damage induced by extracapsular cataract extraction was simulated by puncture of the anterior capsule using a 26‑gauge hypodermic needle...

Purpose. Analysis of functional outcome and complications reported in patients diagnosed with phacomorphic glaucoma, in which phacoemulsification or extracapsular extraction of the lens was performed. Methods. The retrospective study included 38 eyes diagnosed with phacomorphic glaucoma. In 25 cases, group 1, the lens was removed by phacoemulsification and in 13 cases, group 2, by extracapsular extraction.

PURPOSE: To evaluate intraoperative complications during phacoemulsification of intumescent cataract using lens decompression technique. METHODS: Participants with intumescent cataract scheduled for phacoemulsification were recruited and divided into two groups. In both groups, after the anterior capsule was stained with trypan blue, the anterior chamber was filled peripherally with a dispersive ophthalmic viscosurgical device (OVD) followed centrally by a higher viscosity cohesive OVD (Healon GV)...

The manual extracapsular extraction of the lens is the surgical technique that is most practiced for the treatment of cataract in sub-Saharan Africa. Learning this technique requires the creation of a surgical simulation unit within training institutes. We describe the development stages of a traditional simulation unit. For this purpose, we present a description of four steps involved in the development of a simulation unit for cataract surgery: the physical creation of the room, the aseptic and antisepsis conditions, the management of the eyes, the development of a curriculum and the administrative policies...

To evaluate an interlaced triple procedure that involved penetrating keratoplasty (PKP), extracapsular cataract extraction (ECCE) using diathermy capsulotomy, and nonopen-sky intraocular lens (IOL) implantation.This retrospective study involved data from 34 patients who were diagnosed with severe corneal opacities and cataracts. These patients were divided into an interlaced procedure group (21 patients) and a traditional procedure group (13 patients). In the interlaced group, the method of continuous curvilinear capsulorhexis (CCC) was completed via diathermy capsulotomy...

There is a paucity in world literature of a prospective study on post cataract strabismus and in Indian literature on post cataract ptosis. 150 cataract patients without pre-existing strabismus or ptosis were subjected to standard extracapsular cataract extraction with posterior chamber intraocular lens implantation under 2 point peribulbar anaesthesia and were post-operatively evaluated for strabismus and ptosis. At the end of first week, there were 10/150 (6.67%) cases of strabismus, 13/150 (8.67%) cases of ptosis and 5/150 (3...

We report the effect of horizontal extraocular muscle surgery of Heimann-Bielshowsky phenomenon. A 52-year-old woman complained of binocular diplopia for a few months. In 2000, she underwent extracapsular cataract extraction with intraocular lens implantation in the right eye. After surgery, the diplopia persisted and developed further. She showed an esodeviation of 60 prism dioptres at near fixation and distance fixation. Cortical opacity and nucleus sclerosis were observed in the left lens, and phacoemulsification with intraocular lens implantation was performed in the left eye in October 2011...
