Dr. Raymond Stein Is Keynote Speaker at Ophthalmology Meeting at Columbia University in NYC

Saturday, January 12th, 2019

Dr. Raymond Stein was pleased to be a keynote speaker at the 2018 Precision Ophthalmology “Optimizing the Refractive Status of the Eye” meeting at Columbia University in New York City. Held November 30, the meeting gathered ophthalmologists, optometrists and eye care professionals from around North America to discuss the current state of cataract surgery, refractive surgery, dry eye and corneal disease treatments and share information about advances in the field.

In his first talk, Dr. Stein reflected on some of the lessons he has learned in 10 years of performing topography-guided PRK and corneal crosslinking for the treatment of keratoconus. Dr. Stein and his colleagues at Bochner Eye Institute are some of the first doctors in Canada to use this approach to treat the progressive thinning and bulging of the cornea. To date Dr. Stein has performed over 5,000 of these procedures with excellent results.

Later, Dr. Stein spoke about using a corneal laser to treat age-related macular degeneration (AMD), or the deterioration of the portion of the retina responsible for central vision. Bochner Eye Institute is the first practice in North America to use a laser to modify the cornea and improve distance and near vision in patients with AMD. A study conducted by the Bochner team showed that patients who had the laser procedure experienced improvements in both distance and near vision three years after treatment.

Dr. Stein was invited to speak at the Precision Ophthalmology meeting by Dr. Stephen Trokel, a renowned ophthalmologist and a pioneer in refractive surgery. Dr. Trokel developed the excimer laser for vision correction and performed the first human excimer laser surgery in 1987. He also trained Dr. Stein in refractive surgery in 1991.

Earlier in 2018, Dr. Stein spoke at the World Ophthalmology Congress of the International Council of Ophthalmology in Barcelona as well as the Canadian Ophthalmological Society’s annual meeting, which took place in Toronto.

Femtosecond Laser for Creation of LASIK Flap

Tuesday, January 25th, 2011

Dr. Raymond Stein of the Bochner Eye Institute wrote the following clinical update. We hope you find it of interest.

Many reports have demonstrated the superiority of Femtosecond laser created flaps over flaps created with a microkeratome blade: increased flap thickness accuracy,^1,2,3 greater consistency of flap thickness,^4,5 the elimination of button-hole flaps,^1,6 decreased epithelial injury,^{4, 7} greater flap adhesion strength, ⁸ faster visual recovery and better uncorrected visual acuity,^8,9 improved contrast sensitivity,10 better refractive astigmatic neutrality,⁵ decreased higher order aberrations,¹¹ and decreased corneal insensitivity and tear function compromises.^12,13

The laser flap has a uniform or planar thickness. A blade creates a meniscus flap, which results in a thinner flap in the centre and thicker in the periphery. This can lead to one of the most dreaded LASIK complications of a button-hole, which often results in loss of best-corrected vision from irregular astigmatism or scar tissue. When we acquired a Femtosecond laser, four years ago, our initial plan was to offer both the Femtosecond and blade technologies. However, after doing our first cases we quickly sold our microkeratome. All prospective laser patients should be aware that the Femtosecond laser provides the most technologically advanced and safest procedure.

Why would some laser centres continue to offer inferior technology? The answer is very simple — cost. The purchase of a Femtosecond laser costs around $500,000, there is an annual maintenance fee of around $70,000, and a disposable cost (suction ring) of approximately $200 per eye. A microkeratome can be purchased for $25,000 or less, there are no annual maintenance fees and the cost of a blade is around $50 for both eyes. So you can see from a cost point of view there are significant savings for a laser centre to offer inferior technology using a microkeratome.

Femtosecond technology continues to advance. At the Bochner Eye Institute we acquired the first IFS laser in Canada, which has a speed of 150 KHz. This is 2.5 times faster than the previous laser technology. This results in the suction ring being on the eye for less time, thereby providing a more comfortable experience for the patient. In addition, the new technology can create a flap edge greater than 100 degrees. This leads to a more stable flap position like a man-hole cover, and a lower incidence of epithelial ingrowth.

At the Bochner Eye Institute, Raymond Stein, MD, and his team continue to treat a significant number of eye-care professionals from across Canada and the United States. We feel this is because eye doctors understand leading-edge technology and trust our surgical techniques and abilities. To learn more, please contact Bochner Eye and Dr. Raymond Stein today.

Laser vision correction: 20 years of personal experience by Raymond Stein

Wednesday, October 20th, 2010

“Laser vision correction has been an exciting and innovative area of clinical practice. I feel fortunate to have been involved in Excimer laser treatments over the past 20 years. I have used Excimer lasers that were the size of a small bus. I performed treatments that took as long as a full song by the Beatles. I saw patients in the early laser days who if they had to rate their post-op pain on a scale of 1-10 with 10 being the highest, they rated it an 11. Despite this level of discomfort, they all came back for their second eye.” from EyeWorld
