Professor Marguerite McDonald
IMAB Member
Ms McDonald is the Cornea/refractive/anterior segment specialist, Ophthalmic Consultants of Long Island, Lynbrook, NY. She is presently an Adjunct Clinical Professor of Ophthalmology at Tulane University School of Medicine in New Orleans and a Clinical Professor of Ophthalmology at New York University (NYU) in Manhattan.

Dr McDonald received her medical degree from Columbia University College of Physicians and Surgeons followed by an internship at Lenox Hill Hospital and ophthalmology residency at Manhattan Eye Ear and Throat Hospital/Cornell, both in New York City. She completed a fellowship in corneal and external diseases at the LSU Eye Center in New Orleans. She has become well known in the field of refractive surgery with 477 abstracts, 79 books and book chapters and 179 peer reviewed and 280 non peer reviewed articles published on various refractive topics. In New Orleans Ms McDonald headed the research team investigating the use of the excimer laser for the correction of optical error and in 1987 performed the world’s first excimer laser treatment to eliminate or reduce the need for glasses and contact lenses.

Ms McDonald treated blind and fully sighted patients in 1988; both groups were treated for near sightedness. In 1993, she performed the world’s first excimer laser surgeries for far sightedness.

In 1999 Ms McDonald performed the world’s first Summit/Autonomous wavefront-based excimer laser surgeries; these cases were also the first wavefront-based laser surgeries in the U.S. This breakthrough is considered the first step on the road to “super-normal” vision. That is the routine attainment of better-than-20/20 uncorrected vision with minimal aberrations and much improved night vision. Ms McDonald was the first North American surgeon to perform Epi-LASIK in September 2003.

Professor Stephen Slade
IMAB Member
Mr Slade has the longest experience with IntraLase LASIK in the United States and was the first Surgeon there to implant a lens for presbyopia (age-related loss of close up vision). He is a leading Surgeon in the international community as well as in the LASIK Houston community.

He is an active teacher of surgical techniques and has taught and certified over 8,000 Surgeons in LASIK and lamellar refractive surgery. Mr Slade’s experience with lamellar refractive surgery began in 1980 with epikeratophakia, followed in 1983 with myopic keratomileusis. He is highly regarded among other ophthalmologists and is considered to be the “Surgeon’s Surgeon” as over 450 of his fellow eye surgeons have chosen him to perform their own eye surgery. In 1991, along with Stephen Brint MD, Mr Slade performed the first LASIK in the United States. Later he performed the first Custom LASIK ablation based on topography in the United States and has remained on the cutting edge, having the first and longest experience with all-laser LASIK, accommodating intraocular lenses for cataract surgery (crystalens) and implantable corneal contact lens. Mr Slade was a lead investigator and presented the data to the FDA for panel approval for both the crystalens and the implantable contact lens. As part of the trial he implanted the first intraocular lens for presbyopia in North America.

In 2006 the American Academy of Ophthalmology and International Society of Refractive Surgery selected Mr Slade for the 2007 Barraquer Award and Lecture, the top award in Refractive Surgery. His peers have selected him for inclusion in “Top Fifty Opinion Leaders”, “Top Texas Doctors”, “Best Doctors” and “Best Doctors in America”.
