Johnson & Johnson Vision Care presented data at the scientific research symposium of the British Contact Lens Association (BCLA) held during the Netherlands Contact Lens Conference (NCC) that showed 1-Day Acuvue Moist brand contact lenses for Astigmatism (etafilcon A toric soft contact lenses (TCLs)) resulted in significant improvements to quality of life measures compared to its spherical soft contact lens (SCL) counterpart for patients with astigmatism.
“There have been significant innovations in toric lenses, yet patients with low to moderate astigmatism are often fitted with spherical lenses,” Jason J. Nichols, OD, MPH PhD, School of Optometry, University of Alabama at Birmingham, and lead investigator of the study, said in a company news release. “This study shows that visual acuity is significantly improved by about one line versus spherical lenses and there is no difference in fitting time or the number of lenses needed to fit a toric lens – we hope this study can put to rest some of the misconceptions about difficulties fitting astigmats.”
Researchers fitted 60 current SCL wearers age 18-45 years old with -0.75 to 1.75DC binocularly with a SCL and its toric counterpart for 1 week each. A validated patient-reported outcomes questionnaire (National Eye Institute Refractive Error Quality of Life (QoL)-42, NEI-RQL-42i) was used to assess the lens’ impact on vision-specific QoL, in addition to fitting time and success.
Results showed improved visual QoL scores for patients wearing TCL compared to those wearing SCL (overall 74.9% vs 67.6%; vision clarity 75.7% vs 50.1%; correction satisfaction 79.7 vs 62.0%; all p<0.05). Fitting time was similar for TCL as SCL (10.1 vs. 9.0 minutes, respectively) and there was no difference in number of lenses needed for a successful fit (~1.2 average for both).
“We are pleased to be sharing this data at a well-respected and growing international conference where eye care professionals have the opportunity to hear firsthand from researchers. We hope this will add to their clinical knowledge and day-to-day practice to the benefit of astigmats,” said Anna Sulley, BSc MCOptom FBCLA FAA, Associate Director, Global Strategic Medical Affairs for EMA, Johnson & Johnson Vision Care Companies.
