Laser Blended Vision or Micro-Monovision – Raymond Stein, MD

Thursday, April 7th, 2011

This laser correction technique was developed by Dr Dan Reinstein of London, England in 2005. It is another method of monovision. Reading vision is enhanced in only one eye. The technique induces negative spherical aberration, a higher-order aberration, to increase the depth of focus. This results in enhanced reading with a slight decrease in distance acuity. Dr.

Raymond Stein reviewed this method of correction at the University of Toronto, Walter Wright meeting in 2009. We have offered this technique at Bochner since 2007. Presbyopic patients that tolerate traditional monovision are the best candidates for laser blended vision.

A detailed video summary of Laser Blended Vision by Dr Reinstein is available at www.youtube.com/watch?v=JVGnb6ZIzLk.

Dr. Raymond Stein Speaks at ASCRS

Thursday, April 7th, 2011

Dr. Raymond Stein was an invited guest speaker to the annual meeting of the American Society of Cataract and Refractive Surgery (ASCRS) in San Diego on March 28, 2011. He presented the results from the Bochner Eye Institute of Corneal Collagen Crosslinking with up to 3.5 years of follow-up. None of the treated patients have shown any progressive ectasia. Crosslinking has been shown to be a major advance in the treatment of keratoconus, pellucid marginal degeneration, and ectasia after refractive surgery. The surgeons at the Bochner Eye Institute have been pioneers with this technology in North America. To learn more about Raymond Stein, MD, & Bochner Eye Institute, please call (416) 960-2020.

Dry Eyes – Symptoms & Treatment – Dr. Raymond Stein

Thursday, April 7th, 2011

As a benefit to individuals who think they might be suffering from dry eye syndrome, Dr. Raymond Stein, a leading Toronto LASIK and keratoconus doctor, has provided an in-depth look at the symptoms, diagnosis and treatment of dry eyes. Please read the article below to learn more. If you have any further questions, please use the contact form below or call Raymond Stein, MD & Bochner Eye Institute at (416) 960-0220.

Dry eye is an extremely common condition that results in symptoms of irritation, burning, and/or light sensitivity. The symptoms are typically worse later in the day. Symptoms can be exacerbated with activities that involve starring such as the use of a computer, watching TV, or driving.

The tear film is composed of three layers: mucin, aqueous, and lipid layers. The mucin layer coats the anterior surface of the eye and holds the thicker aqueous layer.The lipid layer, which is secreted by the meibomian glands, is the most external layer, and prevents evaporation of the tears.

Abnormalities of the quality or quantity of any of the tears layers can result in symptoms of a dry eye.

The diagnosis of an aqueous deficient dry eye is based on the presence of typical symptoms, a scant tear film, a rapid tear breakup using fluorescein dye, or punctate staining of the cornea. The diagnosis of meibomian gland dysfunction is the presence of stenotic meibomian gland orifices or a foamy tear film.

The most common mode of treatment of an aqueous deficiency is the use of artificial tears, gels, or ointments. Increasing humidity in the home can help the level of comfort.  Punctual plugs can be placed in the puncta of the lids to decrease the drainage of tears and reduce symptoms. Cyclosporin eye drops (Restasis) can be prescribed that act on the tear glands to enhance tear production.

There is recent evidence that meibomian gland dysfunction is the most common form of dry eyes. In addition to the use of lubricating medication the oral use of Doxicycline can improve the quality of the meibomian secretions. Hot compresses are helpful in expressing the meibomian gland secretions. An innovative new treatment modality will be available in the near future that will permit direct heat application to the inside of the lids and an automated gentle compressor to the outside of the lids to express the meibomian secretions. Clinical studies have shown that a single treatment that takes 12 minutes can enhance comfort for 12 months.
