About this study

Addition lenses are often used to treat a range of eye conditions. Addition lenses are specifically used to help patients who do not have the ability to focus their eyes to see clearly up close. Eye focusing is called accommodation. Addition lenses are easy to prescribe in a pair of glasses and are often called the bifocal portion of the glasses. Addition lenses can be used for adults who have presbyopia (they cannot read up close without the aide of a bifocal) and for patients of all ages who have eye focusing problems (e.g. accommodative insufficiency, accommodative infacility, accommodative dysfunction).

Addition powers can also be put into contact lenses. Contact lenses that have addition powers in them are called multifocal contact lenses. These are often marketed for patients that are 40 and over who have presbyopia, and are prescribed to help patients see up close as well as far away in their contact lenses. Multifocal contact lenses are also used in children with nearsightedness because studies have shown that some multifocal designs can slow down the progression of nearsightedness. As stated before, addition lenses can be used to treat eye focusing problems in patients of all ages, before presbyopia. What is unclear is whether the addition power in contact lenses has the same treatment effect as an addition power in a pair of glasses when they are being used to treat eye focusing problems. This study will assess how different kinds of multifocal contact lenses (center distance or center near) will change eye focusing and eye teaming in young adult patients.

Read the detailed description

Soft multifocal contact lenses are used for a variety of reasons in patient care. In fact, studies have shown that soft multifocal contact lenses alter accommodation. While most often used to correct presbyopic vision, these lenses are also used in the management of accommodative and binocular vision disorders along with myopia management. Multifocal contact lenses correct vision at different distances by introducing a power gradient over the eye thus providing a range of clear vision at both distance and near.

For center near designs, the near addition is placed in the center of the lens, and the power becomes more negative in the periphery. Generally, it is thought that center near designs provide the most accommodative relief and superior near vision because the near addition is centered in the pupil. These lenses allow maximum near correction, even with miotic pupil size changes associated with accommodation. Conversely, for center distance designs, the distance prescription is placed in the center, and the power of the lens becomes more positive in the periphery to provide the near addition. To date, most studies have used center-distance lens designs to evaluate accommodative ability and function. Accommodative function while wearing center near lenses has likely not been studied often because these lens designs are used most in populations with no or waning accommodative ability (i.e. presbyopic patients). In this population lenses are used, specifically, to account for that accommodative inability.

Center near and distance designs have varying advantages and disadvantages for presbyopic vision correction. Selection of lens design can be based on a patient's individual visual needs. There is conflicting evidence on whether the add power in soft multifocal contact lenses can be used to manage accommodative and binocular vision disorders. These lenses do offer relief of accommodative demand associated with both accommodative and binocular vision disorders. It has been hypothesized that center near multifocal contact lenses provide a greater therapeutic effect as the central portion of the lens is the addition power. There have been case reports demonstrating benefits of multifocal contact lenses in accommodative insufficiency and convergence excess. Center distance lenses are used most often for myopia management. In these situations, the interest has been to determine if the child can maintain normal accommodative function while wearing the lenses. This study will aim to determine how accommodative function varies with center distance and center near multifocal contact lenses.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Objective Accommodative Response (in Diopters) on the Grand Seiko Autorefractor at 2.5 Diopters (40 cm)

    Accommodative function will be compared using the Grand Seiko Autorefractor between the center distance and center near group. The instrument will record the patient's refractive error at near (40 cm), which is commonly used for near assessment in clinic. Patients place their head on a chin rest and look at targets at different distances. The examiner then pushes a button and the refractive error (in Diopters) is recorded from the instrument and placed in an excel file to be analyzed.

    Measured: Up to two hours (1 hour in each lens)

Secondary outcomes (5)
  1. Accommodation (in Diopters) Measured by Monocular Estimation Method (MEM)

    Accommodation was assessed by monocular estimation method which is done with a clinical retinoscope, in which the examiner looks at the light reflex of the retina and the patient reads small print at 40 centimeters and the examiner uses lenses to neutralize the reflex

    Measured: Up to two hours

  2. Accommodation (in Diopters) Measured by Monocular Push-Up

    Accommodation measured with a monocular push-up was measured by the examiner bringing a small target close to the eye and the patient reports when the target gets blurry. These eye focusing tests and outcomes will be compared in the lens types.

    Measured: Up to 2 hours

  3. Accommodation (in Cycles Per Minute) Measured by Accommodative Facility

    Accommodation was assessed by accommodative facility which uses lenses to determine how many times a patient can clear a target in one minute by having the patient look at print 40 centimeters away and the examiner places a plus lens in front of the eye and the patient reports when the text is clear and the examiner flips the lens to a minus lens and the patient reports when the text is clear and this is done for one minute and cycles per minute are recorded

    Measured: Up to 2 hours

  4. Phoria (in Prism Diopters) Measured by Modified Thorington at Distance

    Vergence measures will be completed by Modified Thorington will be assessed at distance (20 feet) which is a card with a light in the center. The patient holds up a red lens over their eye and they report where they see the line crossing the cards. This is recorded in prism diopters. This is tested with all lens types.

    Measured: Up to 2 Hours

  5. Phoria (in Prism Diopters) Measured by Modified Thorington at Near

    Vergence measures was completed with Modified Thorington will be assessed at near (40 centimeters), which is a card with a light in the center. The patient holds up a red lens over their eye and they report where they see the line crossing the cards. This is recorded in prism diopters. This is tested with all lens types.

    Measured: Up to 2 hours
