Presbyopia Diagnosis and Treatment

As we reach middle age, particularly after age 40, it is common to start to experience difficulty with reading and performing other tasks that require near vision. This is because with age, the lens of our eye becomes increasingly inflexible, making it harder to focus on close objects. This condition is called presbyopia and eventually it happens to everyone who reaches old age to some extent.

To avoid eyestrain, people with untreated presbyopia tend to hold books, magazines, newspapers, and menus at arm’s length in order to focus properly. Trying to performing tasks at close range can sometimes cause headaches, eye strain or fatigue in individuals who have developed this condition.

Causes of Presbyopia

During our youth, the lens of our eye and the muscles that control it are flexible and soft, allowing us to focus on close objects and shift focus from close to distant objects without difficulty. As the eye ages however, both the lens and the muscle fibers begin to harden, making near vision a greater challenge.

Presbyopia is a natural result of the aging process and not much can be done to prevent it. Its onset has nothing to do with whether you already have another vision impairment such as nearsightedness, farsightedness or astigmatism. Everyone will notice some degree of loss of near vision focusing power as they age, although for some it will be more significant than others.

Symptoms and Signs of Presbyopia

Presbyopia is characterized by:

  • Difficulty focusing on small print
  • Blurred near vision
  • Experiencing eyestrain, fatigue or headaches when doing close work or reading
  • Needing to hold reading material or small objects at a distance to focus properly
  • Requiring brighter lighting when focusing on near objects

Presbyopia can be diagnosed in a comprehensive eye exam.

Treatment for Presbyopia

There are a number of options available for treating presbyopia including corrective eyewear, contact lenses or surgery.

Eyeglasses

Reading glasses or “readers” are basically magnifying glasses that are worn when reading or doing close work that allow you focus on close objects.

Eyeglasses with bifocal or multifocal lenses such as progressive addition lenses or PALs are a common solution for those with presbyopia that also have refractive error (nearsightedness, farsightedness or astigmatism). Bifocals have lenses with two lens prescriptions; one area (usually the upper portion) for distance vision and the second area for near vision. Progressive addition lenses or PALs similarly provide lens power for both near and distance vision but rather than being divided into two hemispheres, they are made with a gradual transition of lens powers for viewing at different distances. Many individuals prefer PALs because unlike bifocals, they do not have a visible division line on the lens.

Bifocal and Multifocal Contact Lenses

For individuals that prefer contact lenses to glasses, bifocal and multifocal lenses are also available in contact lenses in both soft and Rigid Gas Permeable (RGP) varieties.

Multifocal contact lenses give you added freedom over glasses and they allow you to be able to view any direction – up, down and to the sides – with similar vision. People wearing progressive lenses in glasses on the other hand have to look over their glasses if they want to view upwards or into the distance.

Another option for those that prefer contact lenses is monovision. Monovision splits your distance and near vision between your eyes, using your dominant eye for distance vision and your non-dominant eye for near vision. Typically you will use single vision lenses in each eye however sometimes the dominant eye will use a single vision lens while a multifocal lens will be used in the other eye for intermediate and near vision. This is called modified monovision. Your eye doctor will perform a test to determine which type of lens is best suited for each eye and optimal vision.

Surgery

There are surgical procedures also available for treatment of presbyopia including monovision LASIK eye surgery, conductive keratoplasty (CK), corneal inlays or onlays or a refractive lens exchange (RLE) which replaces the hardened lens in the eye with an intraocular lens (IOL) similar to cataract surgery.

Since it affects so much of the older population, much research and development is going into creating more and better options for presbyopes. Speak to your eye doctor about the options that will work best for you.

Dear Northwood Vision patient,

COVID-19 has the potential to cause grave harm to many of the citizens in our population. According to Harvard epidemiologist Dr. Mark Lipsitch it is likely that at least between 40-70 % of the population will become infected with COVID-19. This virus is twice as contagious as the flu. About 80 percent will not have severe concerns, but based on the current data, 20% of the infected will become severe or critical, needing some form of hospital care to do well. Currently, about 30 % of those who become classified as severe based on WHO classification, will not survive. These are the unfortunate realities at the moment.

Meanwhile, at Northwood Vision, we want to do as much as possible to minimize this risk, to prevent mortality and long term side effects, while doing our best to provide the services our patients need. We are convinced you care about these same things. (Read more)

Here is what we are asking you to do to make a smaller exposure footprint:

  1. If you have any symptoms of a cold or flu (coughing, fever, difficulty breathing, running nose, etc), please reschedule your appointment for at least one month from now.
  2. Try not to touch any surfaces in the office you do not have to touch.
  3. If you are trying on glasses, DO NOT put the frames back on the shelf. Rather, we will collect them from you for proper cleaning before they are returned to the shelves.
  4. If you are ordering contact lenses, a year supply (and some 6 month supplies) order can be direct shipped to your home at no cost. Please take advantage of this so you don’t have to come into the office more than necessary.
  5. If you do need to come into the office for an adjustment, please call the office at 727-725-5558 when you arrive in your vehicle. We will let you know if there is a wait and will put you on a list so we can call or text you to come therefore minimizing the time you are in the enclosed space of our office.
  6. Please come to your appointment with the least number of people possible to reduce exposure to them and to others at the office.
  7. If you have any loved ones that have been exposed to the virus or certainly if they have symptoms of a respiratory illness, please wear a mask in case you are an asymptomatic carrier, or if possible, wait at least 4 weeks before coming in for non-essential care.

In an effort to protect you, here is what we are doing to help lower your risk:

  1. All surfaces in the office will be cleaned several times per day with antiviral/antibacterial cleaner. Surfaces in the exam room will be cleaned thoroughly in between each patient.
  2. No sick or symptomatic staff will be permitted to work while sick with a known viral respiratory infection or symptoms, or while directly caring for a sick relative/friend.
  3. For your safety, payments can be done ahead of time over the phone if you call ahead. This will decrease the amount of time you are in the store and your exposure risk in our enclosed space.
  4. No glasses frames other patients try on will be put back on display until the frames are cleaned with an antiviral cleanser.
  5. We are actively asking patients to reschedule for 4 weeks later if they have any symptoms themselves or in their family/ social network.
  6. We are giving options for patients to acquire goods by mail rather than coming into the store.
  7. We altering our schedule to decrease the number of patients that might be in the office at the same time to maximize social distancing.
  8. We are practicing frequent hand washing at our office to protect you and each other.
  9. We will ask patients to reschedule if they present to our clinic with a cough or other COVID-19 symptoms.

Thank you for your patience and understanding during this stressful and trying time. Let us all work together to lower risk of the spread so that less people die and less people have permanent side effects from COVID-19. Each of us can do our part. May God bless each of you and keep you well. Thank you for your understanding and care for your fellow humans.

Dr. Christopher K. Keats, OD
