Background: The pulsed electron avalanche knife (PEAK-fc) is a new pulsed electrosurgical device that allows for precise, ‘‘cold’’ and traction-free tissue dissection. Aim: To evaluate the surgical applicability, safety and potential complications of PEAK-fc in complicated cataract surgery. Methods: The study included five children with congenital cataracts, two patients with advanced senile ca...

Purpose To report our diagnostic ultrasound-based approach and surgical strategy in a case of severe blunt trauma with complete hyphema, 270° iris disinsertion, and traumatic subluxated cataract. Case Report A 70-year-old male was referred to our hospital for a blunt trauma in his right eye. A complete examination revealed visual acuity consisting in light perception, a complete hyphema, and ...

PURPOSE To determine the nature and the origin of metallic foreign particles appearing on the iris after phacoemulsification surgery. SETTING P.D. Hinduja Hospital and Medical Research Centre, Mumbai, Maharashtra, India. DESIGN Case series. METHODS Metallic foreign particles were observed on the iris surface and the pupillary border on the first postoperative visit after phacoemulsificati...

PURPOSE We describe our successful experience using a capsular tension ring (CTR) and iris repair during cataract surgery in a patient with bilateral coloboma. METHODS A 67-year-old woman had no history of trauma, but had zonular deficiency and inferonasal iris defects in both eyes. An extracapsular cataract extraction and intraocular lens (IOL) scleral fixation was performed in the left eye....

We studied ouabain-sensitive Na-K adenosine triphosphatase (ATPase) activities in the iris-ciliary body of rabbit eyes after lensectomy-vitrectomy. Changes in enzyme activities were quantitatively investigated in the plasma membrane of iris-ciliary body at 0 or 7 hours and at days 1, 3, 7, and 14. The specific activity of Na-K ATPase rose to significantly higher levels than the control value at...

Antibiotics such as fluoroquinolones (FQLs) are commonly used to treat ocular infections but are also known to cause dermal melanocyte toxicity. The release of dispersed pigments from the iris into the aqueous humor has been considered a possible ocular side effect of the systemic administration of FQLs such as Moxifloxacin, and this condition is known as bilateral acute iris transillumination ...

anterior megalophthalmos is characterized by megalocornea associated with a very broad anterior chamber and ciliary ring elongation. it is also known as x-linked megalocornea. it is accompanied by the early development of cataracts, zonular anomalies, and rarely vitreoretinal disorders. cataract surgery involves the risk of subluxation of the cataract because zonular weakness. in addition, in m...

Background: A number of ocular biometric parameters, iris hiotologic and anatomic characters have been suggested as inciting factors for converting patients with narrow angle to angle-closure glaucoma. This study was conducted to determine if there was any goniscopic difference between patients with acute angle-closure glaucoma (AACG) and chronic angle-closure glaucoma (CACG). Methods: ...

Early reformation of the anterior chamber after intraocular surgery is of paramount importance, its absence or delay leading to peripheral anterior synechiae and aphakic glaucoma (Troncoso, 1933; Kronfeld and Grossman, 1941; McLean, I94I; Meyer and Sternberg, 1950). Selinger (1937) injected air after cataract operations to restore the normal curvature of the cornea. He concluded that air preven...

BACKGROUND The purpose of this review was to provide a critical appraisal of the literature supporting the efficacy of ophthalmic ketorolac (Acuvail(®)) in the treatment of pain and inflammation after cataract surgery. METHODS Literature search and expert opinion of the authors. RESULTS Recent studies indicate greater intraocular drug levels in the anterior chamber and iris-ciliary body aft...
