Price Vision Group to Participate in National Sight Week

Local Eye Surgeons Will Provide Free Cataract Surgery

Indianapolis, IN – Price Vision Group is pleased to announce its participation in the 2nd annual National Sight Week (October 15-21), sponsored by the American Society of Cataract & Refractive Surgery (ASCRS) Foundation.
During National Sight Week, Dr. Francis Price, Jr, Dr. Matthew Feng and Dr. Sheila Pabon will be performing free cataract surgery for local, eligible patients.
National Sight Week is a celebration of volunteerism, during which members of the ASCRS Operation Sight network are encouraged to contribute one or more charitable cataract surgeries in their own communities. The ASCRS Foundation works to match needy, eligible patients with volunteer surgeons, and will provide a financial stipend for each surgery completed.
Operation Sight is the ASCRS Foundation’s domestic charitable cataract surgery program. Its mission is to assist uninsured American patients who can’t obtain cataract care on their own. By leveraging the combined strength of established charitable organizations along with ASCRS-member volunteer surgeons, Operation Sight provides needed care to those unable to access or afford surgery.
“The ASCRS Foundation’s Operation Sight initiative offers a solution for Americans in need by enabling ASCRS member eye surgeons to perform charitable cataract surgeries in their own communities with administrative and financial support from the ASCRS Foundation. Together, we’re working to end preventable cataract blindness in the United States,” says Dr. Stephen Lane, MD, Domestic Initiatives, co-chair of the ASCRS Foundation.
Price Vision Group is currently identifying potential, eligible patients to receive free cataract surgery as a part of the practice’s participation in National Sight Week. Individuals interested in being considered as a surgery candidate can visit OperationSight.ASCRS.org to apply. Potential candidates are encouraged to apply as soon as possible to complete the vetting process in time for surgery.

The American Society of Cataract and Refractive Surgery Foundation is a 501(c)(3) organization founded in 2003. Through its projects in the United States and overseas, the foundation works to improve physician education and to deliver humanitarian eye care. ASCRSFoundation.org

Soft contact lenses have an inherent problem with trying to correct astigmatism.
The problem is that with each blink, contact lenses not only move up and down, they
also rotate either clockwise or counter clockwise. The rotation does not matter if
the correction is only spherical (meaning nearsighted or far sighted corrections).
However with astigmatism, the curvature of the corneal surface and the curvature of
the contact lens each vary in different directions (like the shape of an American
football). When the lens is in perfect position, everything is great, but then we have
to blink and the lens rotates a few degrees, and with the next blink a few more
degrees. Suddenly the soft contact lens is no longer correcting the disparity in
curvature, in fact when it rotates 90 degrees it actually makes the astigmatism twice
as bad as it was before!! In order to compensate for this rotational movement, soft contact lenses for
astigmatism are frequently made with ballasts or prisms so that when an eye blinks
and the lens rotates, the ballasts or prisms cause the lens to rotate back. This helps,
but many patients find this disorienting – especially as the two eyes rotate the
lenses in opposite directions. All contact lenses have to move up and down a little
with each blink to keep tears moving in and out from under the lens. So with each
blink the vision is made a little blurry with contact lenses, even spherical ones. But
with astigmatism we also get rotational disorientation typically different for the two
eyes. This is why many people don’t even have their astigmatism corrected at all
with their soft contact lenses. Lasik is far superior to soft contact lenses in correcting
astigmatism because the correction is applied directly on the surface of the eye.
The correction does not move with each blink; instead, it is stable in any direction of gaze.

Cataract surgery for a keratoconus patient does require some additional testing and consideration for the best visual outcomes. Choosing the appropriate lens and lens power can be more challenging with keratoconus. The length of the eye and the shape of the cornea are important factors when calculating an intraocular lens (IOL).

If you are wearing a contact lens it is important that the lens be discontinued prior to your eye exam. At Price Vision Group we recommend discontinuing rigid gas permeable contact lenses for 2 weeks and soft contact lenses for 1 week prior to your cataract exam. This will allow the cornea to return to its natural shape in order to accurately evaluate the degree of corneal astigmatism and eye length. Regular astigmatism is linear and can be corrected with glasses and irregular is not linear and cannot be corrected with glasses correction. A rigid gas permeable contact lens can correct irregular astigmatism.

The correct IOL is very important for the keratoconus patient. The monofocal IOL is the “standard” IOL. This IOL is covered by most insurance plans and works well for low amounts of regular astigmatism or irregular astigmatism. If a patient has irregular astigmatism a rigid gas permeable contact lens may still be indicated after cataract surgery to correct the irregular astigmatism.

A toric IOL can be a good option to correct higher amounts of regular astigmatism in keratoconus cataract patients. These lenses can improve your uncorrected visual acuity and significantly reduce your dependency on glasses post cataract surgery. It can be more difficult to fit contact lenses with a toric IOL, so this should be considered prior to a toric IOL selection. Glasses can be worn post operatively, if needed, to correct any residual refractive error. A toric IOL is considered a “premium” IOL and is not covered by insurance.

A multifocal IOL is not a good option for most keratoconus patients. The multifocal IOLs are best when the cornea is pristine and obviously if you have keratoconus your cornea has irregularities. The multifocal IOL is not a good option for those with keratoconus.
When you are ready for cataract surgery accurate pre op testing and IOL selection are key to the best visual results.
