Prevalence of Astigmatism in Patients Undergoing Cataract Surgery at a Tertiary Care Center in North India.

Aim: To assess the demography, magnitude, and type of corneal astigmatism in patients undergoing cataract surgery in North India.

Methods: It is a clinic-based, cross-sectional, observational study. Keratometric values and demographic data were collected for eligible patients who had undergone phacoemulsification at a tertiary eye care center between January 2010 and December 2017, using a non contact, optical low coherence reflectometry (OLCR).

Safety and efficacy of Ahmed glaucoma valve implantation in refractory glaucomas in Northern Indian eyes.

Purpose: To evaluate the safety and efficacy of Ahmed glaucoma valve (AGV) implantation in refractory glaucoma in Northern Indian eyes.

Background: The success rate of trabeculectomy remains low in cases of refractory glaucoma even with the use of antifibrotics. Glaucoma drainage devices have proven to be more efficacious in reducing intraocular pressure (IOP) in these glaucomas.

Vitreous occlusion of tube implant in a phakic patient with traumatic glaucoma.

Tube implants or glaucoma drainage devices have become an important method of intraocular pressure reduction when treating complex cases of traumatic glaucoma. However, it is not uncommon to have complications associated with tube implants. The optimal treatment of patients who have undergone glaucoma implant surgery complicated by vitreous incarceration is uncertain.
