This study evaluated the surgical outcome and complications of phacoemulsification and the implantation of an acryl foldable intraocular lens (IOL) with a squared edge in dogs with cataracts. Thirty-two eyes from 26 dogs were examined. The mean follow up period was 75.9 days ranging from 23 to 226 days. The complications after phacoemulsification were posterior capsular opacity (PCO) around the...

AIM To assess the incidence of anterior chamber bacterial contamination during phacoemulsification surgery using an automated microbial detection system (BacT/Alert). METHODS Sixty-nine eyes of 60 patients who had uneventful phacoemulsification surgery, enrolled in this prospective study. No prophylactic topical or systemic antibiotics were used before surgery. After antisepsis with povidone-...

Purpose: To demonstrate an approach to the problems of cataract surgery in extensive iridoschisis Methods: Four eyes of 2 patients with extensive iridoschisis had cataract surgery by the same surgeon using the techniques that resembled techniques for phacoemulsification in intraoperative floppy iris syndrome (IFIS). We used low flow parameters on phacoemulsification, used super-cohesive ophthal...

Phacoemulsification in angle closure can be challenging. Many factors, including large lens, small pupil and a narrow working space in the anterior chamber, contribute towards an increased level of difficulty. Angle closure eyes are also often associated with increased risk of complications such as malignant glaucoma and suprachoroidal hemorrhage. For the inexperienced or the unsuspecting, phac...

Twenty-one dogs were used to study the effects of phacoemulsification and extracapsular lens removal on corneal endothelium and corneal thickness. Specular microscopy revealed preoperative cell morphology and cell densities similar to man. After surgery endothelial cell counts significantly decreased 22% (central) and 13% (periphery) with phacoemulsification and 34% (central) and 31% (periphery...

OBJECTIVE To show how an extending capsulorrhexis can be rescued by a midway tangential capsular flap in order to achieve an uneventful phacoemulsification. DESIGN Consecutive case series. PARTICIPANTS Twenty-two eyes of 22 patients with extending capsulorrhexis treated at the Farabi Eye Hospital, Tehran. METHODS First, a tangential capsular opening was created on the border of the presum...

UNLABELLED Improvements in phacoemulsification technology and instrumentation and intraocular lens materials and design have enabled cataract surgery to be performed through incisions smaller than 2.0 mm in external width. This evolution has occurred over time, with new challenges arising at each step of the decrease in incision size. This article reviews the current trend of using increasingly...

Purpose. To evaluate the outcome of combined vitrectomy with phacoemulsification without postoperative face-down positioning for idiopathic macular holes (MHs). Design. Retrospective, observational case series. Participants. Forty-two eyes of 42 patients with MH. Methods. We studied 42 eyes of 42 cases followed up for 6 months postoperatively. MH closure rate and preoperative and postoperative ...

Dear Sir, I t is known that cataract surgery is challenging in vitrectomized eyes. Cataract surgeons may have encountered with posterior capsular complications and nucleus drop events even with minimal ocular manipulations and low irrigation bottle height. Inadvertent damage to the zonular fibers, posterior or peripheral lens capsule with ocutome or microvitreoretinal (MVR) blade in previous su...

The formation mechanism of a coaxial manganese oxide/poly(3,4-ethylenedioxythiophene) (MnO(2)/PEDOT) nanowire is elucidated herein by performing electrodeposition of MnO(2) and PEDOT on Au-sputtered nanoelectrodes with different shapes (ring and flat-top, respectively) within the 200 nm diameter pores of an anodized aluminum oxide (AAO) template. It is found that PEDOT prefers to grow on the sh...
