The purpose of the present study is to evaluate the iridial microcirculation by fluorescent iridial angiography after laser cataract extraction by using a new extraction device, i.e. "RAKOT", based on the Nd:YAG-laser with wave length of 1.44 mcm. 25 eyes (21 patients) aged 71 to 87 with mature senile cataract were examined. The method of laser cataract extraction was used in 14 cases. These eyes made up the main examination group. As for the controls (11 eyes), the manual technic of cataract extraction was used for them. The results in the main group show that the degree of the response of the iridial microvessels to surgery is insignificant and the microcirculation restores completely in 1.5-2 months after surgery provided there are no initial pathological changes in the iridial microcirculation (3 eyes). A short-time intensification of permeability of the iridial microcirculation is possible in eyes with a pronounced initial pathology in the iris (11 cases), however it restores to the original level during 3-3.5 months after surgery. The iridial microcirculation restores in the controls during 3 months after surgery. The described data demonstrate that the laser cataract extraction does not lead to pronounced iridial vascular disorders. A comparison with the controls is indicative of a lower trauma in case of laser method versus the manual technic of lens extraction.

Purpose: To assess the effect of anterior chamber depth on corneal endothelium using specular microscopy following uneventful phacoemulsification among cataract patients with different axial lengths.
Methods: The study was conducted in a quasi-experimental design including 300 eyes of 300 patients with grade three age-related nuclear cataract distributed equally based on their axial length into three equal groups. All eyes had grade three nuclear cataract.

Peribulbar anesthesia is mainly used for cataract surgery. Many studies had used atracurium and rocuronium as an additive to the local anesthetic (LA) drugs in eye surgery. The aim of this study is to evaluate the efficacy of adding atracurium versus rocuronium to a local anesthetic mixture, in providing an early onset of orbital akinesia and corneal anesthesia during cataract surgery.

Purpose: The volume of the vitreous chamber varies with the size of the eye. The space created in the vitreous cavity by a vitrectomy is called the vitrectomized space. The volume of the vitrectomized space is strongly correlated with the axial length of the eye.

A 70-year-old man developed intermittent fever with chills, severe anorexia, generalized weakness, and mild exertional difficulty in breathing following posterior chamber intraocular lens replacement surgery for a mature white cataract in the left eye. Laboratory tests revealed persistent negative blood cultures, normocytic and normochromic anemia, neutrophilia, and elevated inflammatory markers despite multiple courses of antibiotics. All other investigations conducted to identify the cause of prolonged fever, including transthoracic echocardiography, were negative.

Background: COVID-related clinic shutdowns mandated the use of a day 1 telephone follow-up the day after routine cataract surgery rather than clinic attendance. We investigated to see if this is a safe alternative to standard care.
Methods: Ninety-nine patients who underwent a routine cataract extraction between 22 April 2020 and 19 August 2020 at our Hospital were included in this audit.
