Research Interest: Research interest include, Cornea, Immunology, Corneal Nerves, and Imaging.

Research Interest: Corneal collagen cross-linking (CXL) with riboflavin and UV-A. New approaches (e.g. high intensity CXL) and modified techniques (e.g. combined transepithelial phototherapeutic keratectomy followed by CXL - “Cretan protocol”, combined photorefractive keratectomy followed by CXL etc.). New techniques in managing corneal graft for partial corneal transplantation procedures. Development of new techniques for corneal endothelial transplantation (DSEK, DMEK) Femtosecond laser application in corneal, refractive and cataract surgery (e.g. femtosecond laser-assisted intracorneal biopolymer insertion for the symptomatic treatment of bullous keratopathy). Refractive surgery - outcomes and new approaches. Evaluation of corneal ectatic disorders and treatment options. Intracorneal ring segments in keratoconus and post-LASIK ectasia.

Research Interest: Areas of Expertise: Toxicology, Immunology, Genetics

Research Interest: BILATERAL EXUDATIVE RETINAL DETACHMENT AND CHOROIDAL ISCHEMIA AND ASSOCIATED WITH HELLP SYNDROME

Research Interest: Retina and vitreous surgery Macular surgery Cataract surgery Corneal wound healing using a confocal microscope Keratoplasty Eye disorders caused by HIV infection

Research Interest: Dr. Kumar’s research focuses on design and development of public health informatics, telemedicine technology, health education technologies and health informatics technology evaluation.

Research Interest: I am strongly interested in continuing developing new imaging and image analysis methods for preclinical and clinical imaging. I am especially interested in the implementation of new MRI techniques in the routine clinical imaging, surgery, therapy, ophthalmology and/or neurology.

Biography: Dr. Greiner has had over 30 years of continuous grant support for his basic science and clinical research studies. He has been an awardee on grants from both Fight For Sight and the National Society to Prevent Blindness. He has served as principal investigator as well as co-investigator on awards from the National Institutes of Health (NIH) grants and served as an investigator, principal investigator or sub-investigator in over 110 FDA-approved clinical trials. He has been an invited speaker and presenter at numerous regional, national and international meetings, delivering over 200 presentations. With collaborators, Dr. Greiner reported the original clinical and histopathologic characterization and naming of the disease Giant-Papillary-Conjunctivitis, and the original clinical characterization and naming of the ophthalmic condition Lid-Wiper-Epitheliopathy. Dr. Greiner and collaborators also reported the histopathologic and histochemical characterization of the “second” mucus secretory system of the conjunctiva, developed a model of ocular inflammation induced by eye rubbing, developed a method of treatment for meibomian gland dysfunction, and pioneered the applications of 31P NMR spectroscopy in ophthalmology. These discoveries are all documented by his publications in referred medical and scientific journals.
