The lens epithelium is especially vulnerable to oxidative stress. The erosion and shortening of telomeres in human lens epithelial cells in the lack of telomerase activity has been recognized as a primary cause of premature lens senescence phenotype that trigger human cataractogenesis. Carnosine, released ophthalmically from N-acetylcarnosine prodrug lubricant eye drops , at physiological conce...

INTRODUCTION Detachments of Descemet's membrane (DM) occur with not uncommon frequency during cataract surgery. The figure for extracapsular cataract extraction (ECCE) is 2.6%, and that for phacoemulsification is 0.5%. Most detachments are small and of little visual consequence. Large detachments are rare but can lead to loss of vision. Early recognition and appropriate management is the key to...

INTRODUCTION A cataract is characterized by clouding that develops in the crys­ talline lens of the eye or its envelope and varies from a slight to a complete opacity that can obstruct the passage of light. Cataracts are specifically defined as any opacification in one or more layers of the crystalline lens that diffracts light and causes impaired vision. Cata­ ract is the main cause of curable...

AIM The aim of our study was to retrospectively evaluate the effectiveness and safety of cataract surgery and intraocular lens implantation (IOL) for patients aged 90 years or older, whom we define as "very elderly." METHODS The study involved a total number of 122 patients (122 eyes) with senile cataracts. The mean age of patients was 91.2 ± 2.3 years (range 90-100 years old). Phacoemulsific...

AIMS To study the incidence, management, and outcomes of suprachoroidal haemorrhage (SCH) complicating cataract surgery in the United Kingdom. METHODS Cases were prospectively collected by active surveillance through the British Ophthalmological Surveillance Unit. Details were obtained using an incident questionnaire with follow up at 6 months. RESULTS 118 cases were reported in 1 year. The...

Recently I noticed with surprise, during extracapsular cataract surgery, that cortex was retreating from the anterior port of my simcoe cannula during aspiration, instead of being drawn towards it. On closely examining the cannula, I discovered that the infusion entering the luer connection was plumbed to exit at the anterior port, while the syringe was vigorously aspirating anything near the l...

purpose: to investigate the proportion and time trend of second-eye senile cataract surgery (secs) in a high-turnover academic center in iran. methods: in this cross-sectional study, samples were selected among all records of senile cataract surgery based on the international statistical classification of diseases and related health problems, 10th revision (icd-10) during four consecutive years...

BACKGROUND To evaluate the predictability of refraction following immediate sequential bilateral cataract surgery (ISBCS) performed under general anaesthesia. METHODS This is a retrospective review of all ISBCS performed at Kantonsspital Winterthur, Switzerland, between April 2000 and September 2013. The case notes of 250 patients were reviewed. Patients having full refraction reported (110 p...

BACKGROUND Cataract extraction constitutes the largest surgical workload in ophthalmic units throughout the world. Extracapsular cataract extraction (ECCE), through a large incision, with insertion of an intraocular lens has been the most widely used method from 1982 until recently. Technological advances have led to the increasing use of phacoemulsification (Phako) to emulsify and remove the l...
