Objective: To evaluate the efficiency of progressive contact lenses for correction of presbyopia.Material and Methods: Fourty-two eyes of 21 consecutive patients with presbyopia who did not wish to be dependent on reading glasses, were fit with Focus Progressives (CIBAVision, CA, USA).Results: There were three males and eighteen females, and the mean age of the patients was 51.7 ± 4.1 years (range; 47 to 60 years). The mean baseline manifest refraction spherical equivalent was 1.9 ± 1.6 D, mean baseline uncorrected distance visual acuity was 0.7 ± 0.3 LogMAR units (~20/100), mean uncorrected near visual acuity was 0.9 ± 0.1 LogMAR units (~20/200), and the mean near add required was 2.0 ± 0.4 D.Mean follow-up following contact lens disposal was 4.2 ± 1.3 months. At the end of the follow-up period, all patients had 20/20 binocular distance and Jaeger 10 near vision with contact lenses. All patients stated that they had an adaptation period of about a month before they could get used to vision provided by their new contact lenses. Three patients reported that they preferred to wear their regular contact lenses or spectacles for driving, and 5 reported that they used spectacles over their contact lenses for prolonged periods of near work. At month-3, according to tests performed on 10 eyes of 5 patients, a decrease in contrast sensitivity was recorded in 5 eyes for middle spatial frequencies, and a decrease of 1-4 scores in stereopsis was recorded in 2 eyes.Conclusion: In our study, 20 (%96) patients could successfully use their contact lenses throughout the follow-up period. Progressive contact lenses appear to be effective alternatives for presbyopic patients who wish to have simultaneous distance and near vision correction. These contact lenses need an adaptation period, and appropriate patient selection according to motivation and expectations, as well as proper consulting are crucial for a succesful fit.Keywords: Presbyopia, contact lenses,Progressive contact lenses,Presbyopic contact lensesTurkiye Klinikleri J Ophthalmol 2004, 13:88-93
