Tsukiyama, Junko published the artcileEffects of over-the-counter artificial tears and eye wash solutions on multifocal soft contact lenses, Synthetic Route of 194491-31-1, the publication is Nippon Kontakuto Renzu Gakkaishi (2020), 62(3), 108-112, database is CAplus.
The author evaluated the effects of 3 over-the-counter (OTC) artificial tears/eyewash solutions on 6 types of 1-day disposable multifocal soft contact lenses (SCLs). One each of the etafilcon A, nelfilcon A, omafilcon A, SEED 1-day pure, delefilcon A, and nesofilcon A SCLs </div> were immersed in each of the 3 artificial tears/ eyewash solutions: Soft Santear (S), My tear CL (M), and Well Wash Eye (W). After the SCL had been immersed for 5 h in the solution, the size of the SCL was evaluated using Image J. The Etafilcon A SCL had expanded during immersion in S and M and especially during immersion in W (by 14.2%). The nelfilcon A SCL had shrunk during immersion in S and M and especially during immersion in W (by 11.8%). Although exposure of the SCLs to S, M, and W solutions during this experiment was severe compared to exposure during ordinary use of these solutions, the results of the experiment show that there is interaction between these SCLs and OTC artificial tears/eyewash solutions Therefore, SCL prescribers should be careful to evaluate the use of these OTC solutions by their patients.</div>.
