GOOD SUBJECTIVE PRESBYOPIC CORRECTION WITH NEWLY DESIGNED ASPHERIC MULTIFOCAL CONTACT-LENS

Many people of the so-called 'baby-boom' of 1945, nowadays require pre sbyopic correction. A lot of them choose for multifocal contact lenses , but this is not the perfect solution. Decreased visual acuity and co ntrast sensitivity, and appearance of haloes, 'ghosting' and glare are a problem. In this pilot study, with ten randomly, selected, consecut ive patients, a newly designed soft aspheric multifocal contact lens w as tested for visual performance and comfort on day 1 and after six mo nths' wear. Success rate was 80% after six months. Visual acuity was g ood with exception for near vision under low illumination conditions. Two patients mentioned haloes. A statistical significant loss of contr ast sensitivity was recorded on day 1 for the spatial frequencies 6.0, 12.0 and 18.0 cpd (cycles per degree) under high and low illumination . As well as for the spatial frequencies 12.0 and 18.0 cpd under high illumination and 6.0 cpd under low illumination (p = 0.05) after six m onths' wear. Mean overrefraction was limited. All patients recorded go od comfort.
