Sistemas atuais de cuidados e manutenção de lentes de contato

Abstract: A correta manutenção das lentes de contato é fundamental para se obter sucesso e manter a continuidade de seu uso. É grande o número de pacientes que abandonam o uso de suas lentes por problemas que poderiam ser solucionados com tratamentos relativamente simples ou com uma orientação mais adequada. O mau uso das lentes, associado à má adaptação, contaminação, doenças oculares prévias e fatores ambientais, podem aumentar o número de infecções corneanas através da proliferação de microorganismos. O presente arti… Show more

“…This shows that the recommendation by the product manufacturers that it is possible to dispense with rubbing the lens with the fingers when multipurpose solutions are used for cleaning, is questionable. As discussed in a previous study (Lipener and Ray 2008), several factors can contribute to infections in contact-lens wearers, such as poor maintenance and inadequate hygiene, including in this case by eliminating the digital-rubbing step. In another study (Shoff et al 2008), Acanthamoeba trophozoites of different origins, belonging to the T4 genotype, were tested against the hydrogen-peroxide systems and the multipurpose solutions.…”

“…Another problem is crystallization of the serum, in other words, salt (sodium chloride) crystallizes and adheres to the lenses, and may cause discomfort and reduce their useful life. Indeed, the major cause of toxic reactions in contact-lens users is the use of saline, because of the presence of chemical preservatives in its composition (Lipener and Ray 2008). However, a large number of people prefer physiological solutions than other cleaning systems, because of their affordable cost.…”

“…Regarding the solution used to clean the CL, 71.8% of patients use a solution specific for CL, and 28.2% make use of saline, the same way that Lui et al also identified that 78% use multipurpose solution, and 18% use saline (8) . The multipurpose solutions increase the life of CL and help in disinfection, besides being more convenient for patients, facilitating the adherence regarding the conservation of the lens (16) . Oliveira et al did not have the same result.…”

“…The saline has no disinfectant activity and is subject to contamination, even when kept in the refrigerator. All contact lens, regardless of being rigid or soft, disposable or conventional, must go through a process of maintenance including daily cleaning, disinfection and removal of protein deposits (16) . Thus, considering that these procedures as recommended prophylaxis for infection, it can be seen that the care carried out by participants of this research, even by those with less education, are similar to the study of Lui et al (8) .…”
