At the Forefront of Corneal Transplantation & Anterior Segment Reconstruction

Montefiore Einstein Ophthalmology and Visual Sciences’ corneal specialists have helped shape the field of corneal transplantation and anterior segment reconstruction, leading innovations that have set new standards of care. Our experts’ pursuit of innovative approaches to corneal transplantation led to the development of AmbioDry™, a preserved dry amniotic membrane allograft which simplifies and optimizes amniotic membrane transplantation for ocular surface repair. Our ophthalmologists were also instrumental in developing technology that modernized eye banking practices enabling the preparation, storage and national distribution of tissue for endothelial lamellar corneal transplantation. We continue to push the boundaries in corneal and anterior segment surgery, advancing care for patients worldwide.

Research & Publications

Montefiore Einstein leads collaborative research teams and spearheads numerous studies and clinical trials, including several funded by the National Eye Institute/National Institutes of Health (NEI/NIH), that translate novel scientific discoveries into new diagnostics and treatments to improve clinical outcomes. Through our clinical trials, patients gain access to emerging technologies and innovative treatments that may otherwise be unavailable to the general public.

Our research spans basic, translational and clinical science, with a focus on advancing the understanding and management of complex corneal, refractive and anterior segment conditions. Core areas of investigation include the development of novel surgical technologies and techniques; strategies to optimize outcomes in corneal transplantation and refractive surgery; innovations in ocular surface regeneration, and the use of artificial intelligence in cornea, refractive and cataract surgery.

We established new standards of care in cornea, refractive and laser eye surgery, spearheading clinical trials that have led to the development of novel U.S. Food and Drug Administration (FDA)-approved medications and devices. Our experts’ pursuit of innovative approaches to corneal transplantation led to the development of AmbioDry™—a preserved dry amniotic membrane allograft for ocular surface repair. Our physician-scientists were instrumental in developing technology that modernized eye banking practices enabling the preparation, storage and national distribution of tissue for endothelial lamellar corneal transplantation. Our collaborative network has helped bring major therapeutic advancements in the management of anterior segment diseases. 
Our investigations are advancing the understanding of corneal biomechanics before, during and after refractive surgery, assessing long-term outcomes of next-generation laser platforms and femtosecond LASIK  and developing novel crosslinking techniques in refractive correction. Our research includes examining the advances and limitations of scleral lenses for the correction of irregular astigmatism, and leveraging two-photon excited fluorescence microscopy to improve our understanding of the peripheral corneal architecture. We are also studying the effectiveness of emerging biologics and regenerative therapies—including growth factors, autologous plasma products, hyaluronic acid membranes and umbilical cord grafts—as potential treatments for ocular surface disease and neurotrophic keratopathy.

Montefiore Einstein initiated a novel hyaluronic acid membrane (HAM), using a 1,4-butanediol diglycidyl ether (BDDE) cross-linker, a potentially valid treatment for several ocular surface diseases. We also published the first pilot study demonstrating the feasibility of an ultraviolet light-emitting corneal cross-linking (CXL) contact lens device for the treatment of keratoconus. 
Our team is advancing eye banking science through studies that assess donor-related factors influencing corneal transplant success. Recent investigations have examined the impact of donor diabetes mellitus severity on corneal transplant suitability; analyzed corneal endothelial cell loss in eye bank donors who experienced head trauma-related deaths and explored national trends in the screening and utilization of corneas from donors who had undergone prior refractive surgery, leveraging data from the Eye Bank Association of America (EBBA) to inform evolving standards of practice.

About Corneal, Refractive & Anterior Segment Conditions

Corneal, refractive and anterior segment conditions encompass a wide range of disorders that affect the front portion of the eye, including the cornea, iris, lens and the fluid-filled anterior chamber. These structures work together to focus light, maintain eye health and support clear vision, making conditions in this region particularly impactful on visual function and quality of life. Corneal conditions such as keratoconus, Fuchs dystrophy and corneal infections can lead to pain, light sensitivity and vision distortion due to changes in the clarity or shape of the cornea. Refractive errors, including myopia (nearsightedness), hyperopia (farsightedness), astigmatism (uneven focusing) and presbyopia (age-related loss of near focus), occur when the eye cannot properly focus light, resulting in blurred vision. Anterior segment disorders involve structural or functional abnormalities of the front portion of the eye, including the cornea, iris, lens and surrounding tissues and may include conditions such as cataracts, lens dislocation, corneal disease and ocular surface disorders such as dry eye. These conditions can arise from genetic, degenerative, infectious or traumatic causes and may impact vision quality, eye comfort or overall ocular health. Accurate diagnosis and timely management are essential to preserve vision and prevent long-term complications.
