Dr. Dean Evan discoveries continue to be reported in professional scientific journals. His research centers around various clinical subjects concerning the care and treatment of eye disorders and prevention of future eye problems.
Last month, Rheumatology News ran an article about Dr. Hart which described a procedure to manufacture a prosthetic device, "Moisture Chamber Eyeglasses," for the minimization of pain due to severely "dry eye" patients. Due to the fact that there are an enormous amount of nerve endings in the cornea, a dry eye condition can be enormously painful. Even reports of suicide driven by this pain have been recorded.
Moisture chambers are prosthetic devices coupled to eyeglasses that slow the evaporation of the tears from the ocular surface. The need for moisture chamber glasses is most evident when a patient suffers from Sjogren's syndrome. This disease creates a pathologically dry eye from tear anomalies. Other ocular conditions can also cause a painfully dry eye. The concept behind a moisture chamber is to significantly minimize the air flow over the ocular surface. The chamber provides a vapor barrier that functions passively to prevent tear layer evaporation. The chamber provides a humid environment behind the eyeglass lens and in front of the eye surface. This project was undertaken because of the paucity of available information about the production of moisture chamber glasses and the acute need by pathologically dry eye patients for these special glasses.
This month, the journal, CLAO (Contact Lens Association of Ophthalmologists), published Dr. Hart's collaborative study about the surface of contact lens assayed by the high-tech instrumental procedure known as "EIectron Spectroscopy by Chemical Analysis." This instrument is very sensitive to the elemental makeup of a surface's composition. The study approaches the question of contact lens cleaning efficacy with new techniques and finds that current cleaning and maintenance procedures used for contact lenses may not be producing the effect that doctors may think or desire.
A few months ago, Optometry and Vision Science,.which is the official publication of the American Academy of Optometry, published a paper on which Dr. Hart was the feature author. This study is designed to quantify and qualify the microorganism risks related to contact lens wear. Lenses were removed directly out of patients eyes under sterile conditions and assayed for data relating to the microbial bioburden of the situation. Corporate scientists from Bausch and Lomb as well as Cibavision also participated in this not-for- basic research and share coauthorship with Dr. Hart in this important paper. The findings support that the disposal of contact lenses on a regular basis is healthier approach to contact lens wear.
In May of 1993, Dr. Hart presented a paper at the Association for Research in Vision and Ophthalmology (ARVO), in Sarasota, Florida. The presentation detailed a study relating to microorganism flora in the tears, on lids and lashes, as well as contact lenses of long term lens wearers. Relationships were compared between the different ocular sites and patient properties such as lens age, wearing patterns and maintenance procedures.
In the past, Dr. Hart has published several chapters in textbooks and numerous scientific journal articles related to: diet and the tears and contact tens wearers; infection and corneal ulcer prevention; tear film interactions with contact lenses; biochemistry and microbiology of the eye; electron and light microscopy; and epidemiology of eye allergy rates.
Dean Hart, currently director of the Low Vision Clinic at Harlem Hospital Medical Center, gives a day per week from his schedule to help the areas visually handicapped function better. Dr. Hart also instructs the ophthalmology residents at Harlem Hospital Medical Center in refraction, Low Vision care of the visually handicapped, and optics (physical ophthalmic, geometric, and physiological). He also conducts research at Columbia University's Edward S. Harkness Eye Institute where he is provided laboratory facilities and has an appointment as an Associate Research Scientist.
Dr. Hart plans to continue to conduct research about various subjects that are clinically relevant to the care and treatment of his and other eyecare professionals' patients. Besides Dr. Hart' . academic responsibilities he also sees patients at Woodbury Optical Group, 185 Woodbury Road, Hicksville, New York 11801 (516) 681-3937
