News & Events


For patients who have flexible spending accounts (FSAs), don’t forget that your plan year is quickly coming to an end!  While some employers allow a grace period of up to 2-1/2 months to use up your account, most plans require eligible expenses be incurred by December 31, 2017.  Now is a good time to check your balance, file any outstanding claims and use up your account.

Traditionally if you did not use all your FSA balance within a plan year, your balance would be forfeited (the “use it or lose it rule”).  The US Treasury Department recently relaxed this rule to a limited extent.  Employers are now allowed to permit participants to carry over up to $500 in unused funds per year.  You should check with your employer to see if they have adopted this change and of course check your account balance to see how much you have left.

FSAs can be used for certain medical expenses, including:

  • Contact lenses (needed for medical reasons)
  • Medical supplies
  • Dental treatments such as teeth cleaning, x-rays and fillings
  • Eyeglasses; and
  • Hearing aids

Please contact us if you are interested in using your FSA balance toward the cost of LASIK or other vision-related services at NY Vision Group.  

Does Poor Vision Lead to Poor Cognition?

A growing number of studies suggest that poor vision may lead to a decline in cognitive ability.  The latest study published in JAMA Ophthalmology found that among a representative sample of 2975 older Americans, and a second sample of 30, 202 Medicare beneficiaries, poor vision was associated with poor cognition.[1]  

While the study didn’t prove that vision loss caused cognitive decline, according to one of the authors, Dr. Suzann Pershing, “intuitively it makes sense that the less engaged people are with the world, the less cognitive stimulation they receive and the more likely their cognitive function will decline.”  The number of Americans with poor vision is expected to double by 2050 so this study highlights the importance of vision screening to identify patients with eye disease to potentially decrease decreased cognition.  The JAMA study also noted that hearing loss has also been shown to be associated with cognitive decline and dementia.[2]

Dr. Koster and the American Academy of Ophthalmology strong recommend vision screening for the older population owing to the quality of life impact of available treatments for vision problems and now the potential to prevent poor cognition.

NY Vision Group Cyclist Triumphant

Congratulations to David Taylor, a cyclist on NY Vision Group's Fouriclasse team who won the circuit race at the Green Mountain Stage Race on September 2, 2017,  in Burlington VT.  Pictured here, he rode away from the field with 1 kilometer to go to win triumphantly. He went on to win the Queen Stage on September 3 in the soaking rain and high winds and won the four day overall race.  Dr. Koster and NY Vision Group are the lead sponsors for the Fouriclasse team, a New York based amateur cycling sub-team chartered through the Century Road Club Association.  Most of the racers train every day in Central Park in the early morning and compete in races on the weekends across the mid-Atlantic and Northeast regions. 




NY Vision Group is pleased to announce that for the fifth year in a row, Dr. Harry Koster has been named a New York Super Doctor.  You can read more about his accomplishments in the May 14, 2017 special supplement to the New York Times.  The selection process for Super Doctors is a rigorous multi-step process. First Super Doctors creates a pool of candidates based on nominations from local physicians. Doctors may not self-nominate.  Super Doctors' research staff also contributes to the pool based on its "star search credentials".  Candidates are evaluated based on multiple indicators of peer recognition and professional achievement, including experience, professional activities, leadership positions, board certifications, honors and awards, and other outstanding achievements. Then nominees are then grouped into specialties and reviewed by a blue ribbon panel made up of the doctors who, in each specialty, received the highest scores in the nomination and evaluation steps.  Each panelist reviews and evaluates a list of nominees in their area.  Final selection to the Super Doctors list is based on the total points a doctor receives from the nominations, research and blue ribbon panel review steps. Only the highest-scoring doctors are included in the Super Doctors list.  Here is a link to his Super Doctors webpage:

 New Femtosecond Cataract Laser

In our mission to provide patients with the best possible vsion, we pride ourselves on having the most advanced technology and procedures available, combined with superior surgical skills.  To further this mission, we have acquired the new Femtosecond Cataract Laser.

This revolutionary technology allows us to use the laser to make all your cataract incisions, correct astigmatism and soften your cataract just prior to the actual cataract removal. 

Femtosecond-laser assisted cataract surgery is designed to provide the safest, most precise method for the removal of a cataract. Below are samples of the capsular opening the Femto laser makes to permit access to the cataract. The laser is approximately 10x more accurate than manually performing the same task (as demonstrated by the second set of images)
