To describe safety outcomes among wearers of silicone hydrogel (SiHyDD) or hydrogel daily disposable (HydDD) lenses in the 1DAY ACUVUE® TruEye® or 1DAY ACUVUE® MOIST® Performance Overview (TEMPO) Registry (#NCT01467557).
Soft contact lens (SCL) related adverse events (AEs) were identified via self-report (“Yes” to “Have you had a red or painful eye while wearing your CLs since registering for this study that caused you to seek care at your eye doctor or emergency room?”) during 2,894 self-administered electronic questionnaires from 1171 subjects over 1 year from the TEMPO Registry. Years of wear were calculated by lens brand. AE diagnoses were adjudicated by 3 independent clinical experts. Prevalence of risk factors was % of subjects reporting the factor at any survey during the observation period.
The Registry observed 960 years of wear; 489 years of SiHyDDand 471 years of HydDD wear. In that period, SiHyDD wearers reported 8 AEs that resulted in office visits (1.6%/year; 2 corneal infiltrative events (CIEs),0.4%/year), 8 reports without office visits (1.6%/year; e.g., foreign body, symptoms with no visits, allergic conjunctivitis), and 4 (0.8%/yr) with events that were not SCL related (allergic conjunctivitis, conjunctivitis, sub-conjunctival hemorrhage). For the HyDD wearers there were 3 AEs reported that resulted in office visits (0.6%/year; no corneal infiltrative events), 5 reports without office visits (1.1%/year; e.g., allergic conjunctivitis), and 1 AE (0.2%/yr) that was not SCL related (allergic conjunctivitis). Prevalence of risk factors to be reported at any of the 3 study surveys was: Any overnight wear 30%, Storage &Reuse of DD lenses 21%, >5.0D 22%, Age <25 years 31%, Age >50 years 10%, with no difference between lens brands.
Of 1,171 wearers of DDs in the TEMPO Registry with 960 years of wear, only 11, or approximately 1%, had SCL-related complications that prompted clinical visits and only 2 events were CIEs. The event rate with these DD lenses is considerably lower than rates previously reported with reusable SCLs and offers a strategy to improve the safety outcomes with SCL wear. 30% of this post-market sample of DD wearers reported some overnight wear on at least one survey during the year, thus re-training at the time of refitting with DDs is advised.
