A multi‐centre study of lapsed contact lens wearers

Abstract

A high proportion of lapsed contact lens wearers can be successfully refitted with contact lenses. The prime reason for previous discontinuation from contact lenses is discomfort and, in particular, dryness-related discomfort. In many cases, previous contact lens failure is product or practitioner-related rather than because of patient-specific problems. Once refitted with contact lenses, lapsed wearers cite vision problems rather than discomfort as the most common reason for discontinuing. This finding suggests that recent advances in contact lens material, design, replacement frequencies and care systems have improved the prospects for avoiding lens-related discomfort and for continuing contact lens wear.

Hydrogel Contact Lenses Surface Roughness and Bacterial Adhesion

“…In these lenses, it can be observed no substantial preference of P. aeruginosa to adhere to unworn hydrophilic or hydrophobic CL. Although this is consistent with other studies for other bacterial strains (Borazjani et al, 2004;Santos et al, 2008), it challenges the established relationship between microbial adhesion and lens surface hydrophobicity (Pritchard et al, 1999;Doyle, 2000;Young et al, 2002;van Oss, 2003;Giraldez et al, 2010b). This discrepancy could be explained by the different extents of microbial colonization observed for different bacterial strains, and/or the different methodologies employed (Henriques et al, 2005;Kodjikian et al, 2007).…”

Lente de contato de material híbrido em pacientes com ceratocone e astigmatismo miópico composto

“…A mesma já foi usada em pesquisas oculares tais como: dor ocular em pacientes com uveíte (13) , sensação provocada por estimulação corneana (14) , conforto ocular durante a relação de trabalhos em terminais de vídeo (15) e em usuários de lentes de contato rígidas (10) . Segundo a literatura, o desconforto é a principal razão pela qual os pacientes abandonam o uso de lentes de contato (16)(17)(18)(19) . Grande parte dos recentes avanços nos materiais de lentes de contato, desenho e formas de uso e sistemas de limpeza e manutenção das mesmas tem como objetivo reduzir o descon- forto apresentado pelos pacientes (16) .…”

O aumento do conforto e a diminuição de sintomas associados ao olho seco é apontado como o principal fator que pode evitar o descontinuamento do uso de lentes (20) .…”

Demographic and behavioral profile of patients with optic medical indication of contact lenses

“…It is estimated that there are more than 140,000,000 users of contact lenses in the world, being at least 2,000,000 of them in Brazil, according to estimates of Sociedade Brasileira de Lentes de Contato (SOBLEC) (1) . While there are plenty of scientific articles related to unsuccessful adaptation of contact lenses in general and to complications caused by them (2)(3)(4)(5)(6) , there is few data in the literature regarding the conditions of use or not of CL specifically by patients with optical medical indication. There is a lack of consistent studies showing and justifying the lack of use of CL by these patients, since the CL are necessary to have good vision.…”
