After a brief introduction on the history of implantations of synthetic intraocular lenses in Czechoslovakia the authors present an analysis of surgery of cataract and implantation of artificial intraocular lenses during the past five years in Czechoslovakia. The number of operations of cataract increases every year, a substantial increase was recorded in particular in 1992. During the other years there is also a change from intracapsular to extracapsular extraction of cataract and a slow onset of phacoemulsification. The number of departments where artificial lenses are implanted is increasing as well as the ratio of implantations in relation to the total of cataract surgery. In particular during the remaining three years a marked rise of implantation of posterior chamber lenses was recorded and a decline in implantations of iris-clip lenses. Almost 95% of implantations of posterior chamber lenses is considered satisfactory, while less than 60% implantations from the total number of cataract surgery is still insufficient.

Effect of anterior chamber depth on corneal endothelium following phacoemulsification among patients with different axial lengths.

Ophthalmology Department, Faculty of Medicine - Suez Canal University Hospitals, 4.5 Kilo - Ring Road, Ismailia, 41522, Egypt.
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.
