Contact lenses remain one of the most successful methods of vision correction, yet contact lens dropout continues to be a significant challenge for eyecare professionals. New wearers frequently discontinue lens wear within the first 60 days of fitting, and while discomfort dominates the conversation around established wearers, vision problems—not discomfort—are the most commonly cited reason first-time wearers stop lens wear.1
For astigmatic patients, fluctuating or inconsistent vision is a distinct and often underestimated driver of that dropout. For these patients, the relationship between vision quality and successful lens wear is especially important. Providing stable, clear vision can have a direct influence on long-term contact lens success.
Understanding astigmatism and why it matters
Astigmatism is one of the most common refractive errors, occurring when differences in the curvature of the cornea or crystalline lens cause light to focus differently across meridians rather than at a single point on the retina. Reported prevalence varies widely by population and diagnostic threshold—from roughly 8 to 62% of the general population, with higher rates in adults over 70.2
However, even low-to-moderate astigmatism carries a measurable burden:2
- Increased glare (53 to 77% of patients)
- Halos (28 to 80%)
- Night-driving difficulty (66%)
- Spectacle dependence (45 to 85%) severe enough to affect vision-related quality of life
Despite this burden, astigmatic patients have historically been underserved. As recently as 2023, toric soft lens fits accounted for only 46.2% of standard single-vision soft lens fits worldwide—up from 24.4% in 2000.3
When a patient's full prescription was unavailable in a daily disposable, practitioners often had to accept some residual cylinder, move the patient into a reusable toric lens, or explain that their prescription simply wasn't available in their preferred modality.
Daily disposables have become the most commonly prescribed soft lens modality worldwide, rising from 17.1% of daily-wear soft lens fits in 2000 to 46.7% in 2023, reflecting a clear practitioner and patient preference for the modality's convenience and reduced lens-care burden compared with reusable replacement.4
For patients who value that convenience, moving to a monthly toric to get their full prescription can feel like a compromise—even when the monthly lens itself performs well optically.
Why vision drives contact lens dropout
While comfort receives considerable attention, vision should never be overlooked. Patients may report intermittent blur, ghosting, fluctuating clarity, or difficulty with night driving—symptoms consistent with the visual burden of undercorrected astigmatism described above.2
For astigmatic patients specifically, these complaints can stem from residual uncorrected astigmatism or from rotational instability of the toric lens itself. Even well-designed daily disposable torics show measurable on-eye rotation: in one clinical evaluation, roughly 67% of fitted eyes showed zero rotation and just over 90% rotated 5° or less, meaning a minority of fits still drift enough to affect visual crispness.5
Even when a lens is comfortable, inconsistent visual performance can quietly erode a patient's confidence in contact lens wear—and vision, not comfort, is the factor most often blamed by first-time wearers who ultimately stop.1 These complaints may not seem dramatic during a contact lens evaluation but can become significant over time. A patient who repeatedly reaches for glasses because they see better in them may eventually stop reaching for contact lenses altogether.
Expanded parameters: a welcome evolution
Fortunately, manufacturers have continued to expand cylinder and axis availability across daily disposable toric lenses, allowing practitioners to fit a broader range of astigmatic prescriptions.
When I first heard that ACUVUE OASYS 1-Day for Astigmatism was expanding its parameters to include cylinder powers up to −2.75D, I was genuinely excited. This is my go-to daily toric lens because of the comfort and visual stability I see in my patients. Expanding the range means that patients I previously had to compromise on—or move into another modality—may now be candidates for a lens I already know and trust in my practice.
These patients may have been appropriately fit based on what was available at the time. The question is whether that limitation still exists today.
Identifying ideal refit candidates
A parameter expansion is not only about the new patient sitting in the chair. It is also an opportunity to reconsider patients already in the practice. I look particularly at patients wearing undercorrected astigmatism in their current toric lenses, patients wearing reusable torics because their prescription was previously unavailable in a daily disposable, and former contact lens wearers who struggled with visual clarity or stability.
Case illustration
A 29-year-old graphic designer presented and expressed they were interested in returning to contact lens wear after discontinuing approximately 2 years earlier. She had previously worn daily disposable toric lenses but reported fluctuating vision and reduced clarity compared with her glasses. She did not want to switch to a monthly replacement lens, so she ultimately discontinued contact lens wear.
Refraction:
- OD: −2.50 −3.25 × 180
- OS: −2.25 −3.00 × 175
Because her full cylinder correction had not been available in a daily disposable, she had previously been fit with −2.25D of cylinder. Although the lenses were comfortable, her vision remained less crisp than with her spectacles.
With ACUVUE OASYS 1-Day for Astigmatism's expanded toric parameters, we were able to more closely match her refractive prescription while maintaining her preferred daily disposable modality. At follow-up, she achieved 20/20 visual acuity in each eye and reported sharper, more stable vision throughout the day, including improved clarity during prolonged computer work and night driving, while maintaining excellent lens comfort.
The previous lens was not necessarily a poor fit; it was the best fit available within the parameters at the time.
Key clinical takeaways
- Contact lens dropout is driven not only by comfort but, especially in new and astigmatic wearers, by visual performance.1
- Residual astigmatism and rotational instability can measurably reduce quality of vision and, in turn, patient satisfaction.2,5
- Toric prescribing has historically lagged behind the prevalence of clinically significant astigmatism, meaning a meaningful share of existing patients may still be undercorrected.3
- Reviewing existing patient records may reveal candidates for successful refitting as cylinder and axis parameters expand.
Looking beyond the initial fit
Expanded daily disposable toric parameters give practitioners an opportunity to rethink what may be possible for astigmatic patients. As prescription ranges evolve, some of the compromises previously accepted may no longer be necessary. As available parameters expand, so should expectations for what can be provided to astigmatic contact lens patients.
