- ItemAcesso aberto (Open Access)Adaptação de lente de contato gelatinosa especial para ceratocone(Conselho Brasileiro de Oftalmologia, 2006-08-01) Yamazaki, Ester Sakae [UNIFESP]; Silva, Vanessa Cristina Batista Da [UNIFESP]; Morimitsu, Vagner [UNIFESP]; Andrade Sobrinho, Marcelo Vicente de [UNIFESP]; Fukushima, Nelson [UNIFESP]; Lipener, César [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)PURPOSE: To evaluate the fitting and use of a soft contact lens in keratoconic patients. METHODS: Retrospective study on 80 eyes of 66 patients, fitted with a special soft contact lens for keratoconus, at the Contact Lens Section of UNIFESP and private clinics. Keratoconus was classified according to degrees of disease severity by keratometric pattern. Age, gender, diagnosis, keratometry, visual acuity, spherical equivalent (SE), base curve and clinical indication were recorded. RESULTS: Of 66 patients (80 eyes) with keratoconus the mean age was 29 years, 51.5% were men and 48.5% women. According to the groups: 15.0% were incipient, 53.7% moderate, 26.3% advanced and 5.0% were severe. The majority of the eyes of patients using contact lenses (91.25%) achieved visual acuity better than 20/40. To 88 eyes 58% were tihed with lens with spherical power (mean -5.45 diopters) and 41% with spherocylinder power (from -0.5 to -5.00 cylindrical diopters). The most frequent base curve was 7.6 in 61% of the eyes. The main reasons for this special lens fitting were due to reduced tolerance and poor fitting pattern achieved with other lenses. CONCLUSION: The special soft contact lens is useful in fitting difficult keratoconic patients by offering comfort and improving visual rehabilitation that may allow more patients to postpone the need for corneal transplant.
