Smartphone-Based Gonio-Imaging Device
Introduction: The ophthalmic imaging has now revolutionized with the deployment of smartphone for the image acquisition. The widespread adaptability is due to multiple factors, the forefront of which are the availability of good resolution cameras in mid and high-end smartphones, good auto-focusing mechanism, in-built high capacity storage, internet capabilities that enable cloud storage and teleconsultation […]
Cosmetic Rehabilitation of the One-Eyed: Custom-Made Ocular Prosthesis
Loss of an eye deeply affects the individual’s self- esteem particularly in those who have lived the major part of their life seeing the world with both eyes and worse in those who are born with this disability. In addition to this there is loss of binocular vision and depth perception which in turn affects […]
Iris Fixation IOL Technique
Implantation of intraocular lens has become the standard of care for correction of aphakia after cataract surgery. The development of safe and effective IOL s is one of the great successes in ophthalmology. Modern PCIOL’s have a track of remarkable safety and provide excellent visual outcome after uncomplicated cataract surgery. Ideally, we aim for IOL […]
27G Instrumentation – An Emerging Ray of Refinement in MIVS
Vitreo-retinal societies have embarking new technologies in the name of progress which begins as mystic concept to something revolutionising in the surgical filed. After Oshima introduced 27G vitrectomy, it underwent staged adaptation in the background of standard 23G vitrectomy technique since 2010. The advantage of smaller scleral incision (0.4mm compared to 0.5mm of 25G), non-leaking […]
3D Printing in Ophthalmology
3D Printing is a technology where physical objects are created from digital files. It is a disruptive technology which has hasten the development in all fields around us. In health care 3D printing is used to make resorbable airways, titanium implants, functional prosthesis and anatomical models. 3D printing has further developed into “Bio-printing “ where […]
A Quick Review of Minimally Invasive Glaucoma Surgery (MIGS)
Glaucoma is described as a chronic, progressive, optic neuropathy which may be caused by a group of ocular conditions leading to damage to the retinal ganglion cells and optic nerve with corresponding visual field defects.Intraocular pressure(IOP) has been suggested to be the only modifiable risk factor.The main aim of treatment is to lower the IOP […]
Artificial Intelligence in Ophthalmology
Introduction Artificial intelligence(AI), often described as the pivotal technology of the fourth industrial revolution of mankind, refers to the theory and development of computer systems to be able to perform tasks normally requiring human intelligence. Deep learning (DL) is the latest subtype and most powerful AI tool. It uses a data driven approach to teach […]

“It is essential to have good tools, but it is also essential that the tools should be used in the right way.” – Wallace D. Wattles The ‘B-HEX Pupil Expander’ has enabled easy and safe Phaco surgery in eyes with non-dilating pupils. This, in turn, has translated into better visual outcomes. In an online survey […]
Evolution of Endothelial Keratoplasty
Endothelial keratoplasty has come a long way since the inception of the idea of a posterior lamellar transplant instead of full thickness penetrating keratoplasty. With better understanding of the mechanism and increased surgical experience it has become the procedure of choice for management of corneal decompensation. DLEK(1956-99) Deep Lamellar Endothelial Keraotoplasty. Involves replacing the posterior […]
Gonioscopy-Assisted Transluminal Trabeculotomy: A New Ray of Hope!
Glaucoma surgery has seen significant innovations over the past two decades in the form of modifications to penetrating, non-penetrating, and minimally invasive glaucoma surgery (MIGS). Trabeculectomy has stood the test of time, remaining the gold standard for over half a century. As a result of steep learning curves and high-costs, newer techniques are often not […]
