Dr. Nischal attended King's College Hospital Medical School of the University of London and completed ophthalmology residencies at both Birmingham and Midlands and the Oxford Eye Hospital in the United Kingdom. He completed his pediatric ophthalmology fellowship at The Hospital for Sick Children in Toronto. Prior to joining Children's Hospital of Pittsburgh in 2011, Ken was attending at Great Ormond Street Hospital for Children in London, UK. 

Dr. Nischal is one of the pioneers of pediatric corneal transplants. Children from all over the world come to see Dr. Nischal because of his expertise in helping children with genetic corneal diseases. His research focus is on evidence-based protocol led clinical care with clinical outcome measures to drive clinical care. His main areas of clinical research are anterior segment developmental anomalies affecting the cornea, lens, and trabecular meshwork. He has published widely on the topics of pediatric cataract, glaucoma, and cornea as well as craniofacial anomalies.

He is a member of the Scientific Advisory Board of the Pediatric Glaucoma and Cataract Family Association (PGCFA) and has contributed articles and responses to our Ask the Doctor feature. He is the founder and co-director of the World Society of Pediatric Ophthalmology and Strabismus a magnate charity and an outstanding organization with members from around the globe.
