Modern cataract surgery aims to provide patients with the best possible visual outcome with the least dependence on spectacles and minimal or no complications and to treat both cataract and refractive errors with a single procedure. Phacoemulsification is the standard...
Ophthalmology
The textbook is a large, single volume that ideally needs to be desk or table-supported, as its sheer weight makes it virtually impossible to rest comfortably on ones lap. The book is compiled by its two lead authors and editors...Silmo Academy by the IOA hailed a great success

In neuro-ophthalmology we get asked a lot about management of patients who suffered significant trauma and presented with loss of vision secondary to presumed traumatic optic neuropathy (TON). TON happens usually in the context of significant craniofacial trauma. The incidence...Refractive surprise after cataract surgery caused by posterior capsular striae
Cataract removal with intraocular lens (IOL) implantation is one of the most frequently performed surgeries in current clinical practice [1,2]. New microsurgical techniques and refined IOL power calculations allow excellent refractive outcomes. Refractive surprise following cataract surgery is uncommon [1-3]...
Screening for amblyopia
The purpose was to determine the validity of the OPTEC 5500 vision screener in detecting visual acuity and amblyopia in paediatric patients aged 3-17 years with comparison to the Lea and Snellen tests. This was a cross-section study of 64...
Nerve head in healthy humans using OCT-angiography
Optical coherence tomography angiography (OCT-A) is a recent, dyeless, and noninvasive imaging technique for evaluating depth-resolved vascular status by capturing the dynamic motion of the erythrocytes. It provides the flow map of major vessels and capillary plexuses separately in different...Ocular manifestations of multiple sclerosis: an overview
Multiple sclerosis (MS) is an autoimmune demyelinating disease of the central nervous system (CNS), in which there is dissemination of lesions in time (two or more clinical events) and space (multiple lesions seen on brain and spinal imaging). The pathophysiology...
