Advantages of Prescribing the SpecialEyes 54 Multifocal Contact Lens Design
A patient with presbyopia and astigmatism presented with a desire to trial the SpecialEyes 54 Multifocal contact lens design. Previously, the patient tried a daily wear omafilcon B (62%) multifocal contact lens design, wearing a sphere in the right eye and toric in the left eye. However, after various trials he remained unsatisfied with both comfort and vision, particularly his near vision for work. The practitioner shared that the patient was only able to achieve 20/30 vision (with effort) at distance and near with his previous multifocal contact lenses. In addition, the practitioner mentioned that the patient is a heavy depositor. The following information was provided to design a set of trial custom soft multifocal contact lenses:
OD: -3.0 -.50 x167 (+1.75 add)
OS: -4.0 -1.0 x003 (+1.75 add)
4.0mm in a regular room light setting
SpecialEyes 54 Multifocal Toric Trial Lenses:
OD: 8.00 / 14.4 -3.00 -0.50 x167 (+1.75 Add)
OS: 8.00 / 14.4 -3.75 -1.00 x003 (+1.75 Add)
OU Multifocal Optic Zones: 2.0mm near center zone and 3.5mm peripheral zone
Upon insertion, the patient was thrilled with the comfort and visual performance of the SpecialEyes 54 Toric Multifocal contact lens design. During a visual acuity assessment the patient was able to see 20/20 (-) at distance and 20/15 at near. There was no over refraction and slit lamp assessment revealed a good fit with no lens rotation. The patient was instructed to wear the lenses for a week to ensure vision and comfort remained stable. Shortly after, the practitioner called to order the patients year supply.
Why did this multifocal contact lens design work?
During a conversation with one of the SpecialEyes consultants, the practitioner attributed her patient’s success with the 54 Multifocal contact lens design to the following.
- Deposit resistant material
- Exceptional fit and stability
- Ability to correct for the -.50 cylinder in the right eye
- Axes available in 1 degree increments
- Custom multifocal optic zones and pupil size fitting methodology
The bottom line
The SpecialEyes 54 Multifocal has some unique advantages over other multifocal contact lens designs. For starters, the deposit resistant hioxifilcon material that retains its water content provides patients with excellent comfort throughout the day. Practitioners also have the ability to fine tune parameters and powers for a precision fit and prescription with exceptional stability. Finally, the customizable multifocal optic zones allow for the multifocal optics to be appropriately distributed based on the patient's pupil for a nice balance of distance, near and intermediate vision.
