Eye Exams for Contact Lenses

Contact lenses are a great alternative to wearing eyeglasses. An often unknown fact is that not all patients wear contact lenses as their primary source of vision correction. Each patient is different, with some patients wearing contact lenses only on weekends, special occasions or just for sports. That is the beauty of contact lens wear, the flexibility it gives each individual patient and their lifestyle.

If you decide to opt for contact lens wear, it is very important that the lenses fit properly and comfortably and that you understand contact lens safety and hygiene. A contact lens exam will include both a comprehensive eye exam to check your overall eye health, your general vision prescription and then a contact lens consultation and measurement to determine the proper lens fit.

The Importance of a Comprehensive Eye Exam

Whether or not you have vision problems, it is important to have your eyes checked regularly to ensure they are healthy and that there are no signs of a developing eye condition. A comprehensive eye exam will check the general health of your eyes as well as the quality of your vision. During this exam the eye doctor will determine your prescription for eyeglasses, however this prescription alone is not sufficient for contact lenses. The doctor may also check for any eye health issues that could interfere with the comfort and success of contact lens wear.

Hard To Fit Contact Lens Patients

Even if you’ve been told you can’t wear contact lenses, we may be able to help. Specialty contacts are available for patients with dry eyes, severe astigmatism and more.

The Contact Lens Consultation

The contact lens industry is always developing new innovations to make contacts more comfortable, convenient and accessible. Therefore, one of the initial steps in a contact lens consultation is to discuss with your eye doctor some lifestyle and health considerations that could impact the type of contacts that suit you best.

Some of the options to consider are whether you would prefer daily disposables or monthly disposable lenses, as well as soft versus rigid gas permeable (GP) lenses. If you have any particular eye conditions, such as astigmatism or dry eye syndrome, your eye doctor might have specific recommendations for the right type or brand for your optimal comfort and vision needs.

Now is the time to tell your eye doctor if you would like to consider colored contact lenses as well. If you are over 40 and experience problems seeing small print, for which you need bifocals to see close objects, your eye doctor may recommend multifocal lenses or a combination of multifocal and monovision lenses to correct your unique vision needs.

Contact Lens Fitting

One size does not fit all when it comes to contact lenses. Your eye doctor will need to take some measurements to properly fit your contact lenses. Contact lenses that do not fit properly could cause discomfort, blurry vision or even damage the eye. Here are some of the measurements your eye doctor will take for a contact lens fitting:

Corneal Curvature

In order to assure that the fitting curve of the lens properly fits the curve of your eye, your doctor will measure the curvature of the cornea or front surface of the eye. The curvature is measured with an instrument called a keratometer to determine the appropriate curve for your contact lenses. If you have astigmatism, the curvature of your cornea is not perfectly round and therefore a “toric” lens, which is designed specifically for an eye with astigmatism, would be fit to provide the best vision and lens fit. In certain cases your eye doctor may decide to measure your cornea in greater detail with a mapping of the corneal surface called corneal topography.

Pupil or Iris Size

Your eye doctor may measure the size of your pupil or your iris (the colored area of your eye) with an instrument called a biomicroscope or slit lamp or manually with a ruler or card. This measurement is especially important if you are considering specialized lenses such as Gas Permeable (GP) contacts.

Tear Film Evaluation

One of the most common problems affecting contact lens wear is dry eyes. If the lenses are not kept adequately hydrated and moist, they will become uncomfortable and your eyes will feel dry, irritated and itchy. Particularly if you have dry eye syndrome, your doctor will want to make sure that you have a sufficient tear film to keep the lenses moist and comfortable, otherwise, contact lenses may not be a suitable vision option.

A tear film evaluation is performed by the doctor by putting a drop of liquid dye on your eye and then viewing your tears with a slit lamp or by placing a special strip of paper under the lid to absorb the tears to see how much moisture is produced. If your tear film is weak, your eye doctor may recommend certain types of contact lenses that are more successful in maintaining moisture.

Contact Lens Trial and Prescription

After deciding which pair of lenses could work best with your eyes, the eye doctor may have you try on a pair of lenses to confirm the fit and comfort before finalizing and ordering your lenses. The doctor or assistant would insert the lenses and keep them in for 15-20 minutes before the doctor exams the fit, movement and tearing in your eye. If after the fitting, the lenses appear to be a good fit, your eye doctor will order the lenses for you. Your eye doctor will also provide care and hygiene instructions including how to insert and remove your lenses, how long to wear them and how to store them if relevant.

Follow-up

Your eye doctor may request that you schedule a follow-up appointment to check that your contact lenses are fitting properly and that your eyes are adjusting properly. If you are experiencing discomfort or dryness in your eyes you should visit your eye doctor as soon as possible. Your eye doctor may decide to try a different lens, a different contact lens disinfecting solution or to try an adjustment in your wearing schedule.

To Our Valued Patients:

As an essential business, Kennedy Vision Health Center remains committed to patient and employee safety as we navigate through the current healthcare crisis. We are going to see patients again beginning May 4th.  We care deeply about patient health and have implemented several infection prevention measures to ensure the highest level of safety when you visit our clinic.  Following guidance from  the MN Dept. of Labor, MN Dept. of Health, CDC, and the American Optometric Association we are keeping a very controlled and safe environment for our patients and employees.

For patients being seen in our clinic, the CDC is now recommending that all staff, patients and visitors cover their faces in health care facilities. To help reduce the spread of COVID-19, we are requiring patients to bring and wear a face covering (such as protective mask or cloth covering) to any upcoming appointments.

Masks or cloth coverings must be worn over your mouth and nose for the duration of your appointment. Members of your care team will also wear masks to help reduce the spread of COVID-19. If you do not have access to a face covering, the CDC website has guidelines for making no-sew, cloth face coverings. You can also use a scarf or bandana. Additionally, masks can be purchased from many local and online retailers.

We are requiring an appointment to enter the office.  Appointments will be made for eye exams, glasses, and contact lens pickups.  If you do not have an appointment please call before entering so we can make sure we do not have too many people in the office.  Once entering please use the hand sanitizer that is provided in the foyer and wait to approach the front desk until the receptionist is ready.  All people entering the building must have their temperature checked.  If your temperature is above 100.4, it will be rechecked by a different device, and if still high you will need to reschedule.

We continue to ask that you do not bring any unnecessary people with you to your appointment, with the exception of a guardian with a child or assistance with mobility.  Also, please follow the 6 feet social distancing guidelines as much as possible throughout the office.

Rest assured that every surface you come into contact with has been sanitized prior to the arrival of each and every patient entering our practice, and it will be cleaned again as you exit each area. The team will be frequently washing their hands between interactions as per our usual protocol, and you’ll also see hand sanitizer throughout the practice for your use, as well.

If you’re  wanting to purchase glasses, there is a similar protocol in place to ensure a safe interaction with cleaning of frames and minimal contact with our optical team. Please follow their direction if eyewear is needed.

Kennedy Vision Health Center is also offering telemedicine visits which can be completed from the comfort of your home. To schedule a telemedicine visit please contact our office at 763-545-8850 and one of our team members will be happy to schedule your visit.

If you have any questions or concerns, please don’t hesitate to call us. On Monday May 4th we will begin regular office hours at both locations.

We appreciate your efforts to help protect yourself, our care teams and our entire community.
