Purpose: To evaluate the clinical results of the auto-focusing low vision device (EYE FINE) in low vision patients. Methods: We assessed the clinical effect after prescription of the device in 21 patients who visited the low vision clinic from July 2004 to January 2005. We examined visual acuity and contrast sensitivity before and after prescription. Results: Mean distant visual acuity increased from 1.00±0.30 LogMAR to 0.69±0.34 LogMAR and the differences were statistically significant (P<0.01). Mean near visual acuity increased from 0.89±0.25 LogMAR to 0.71±0.30 LogMAR (P<0.01). And mean contrast sensitivities at spatial frequencies of 1.5, 3, 6, 12 and 18 cycles per degree (cpd) increased from 7.9±4.5, 10.8±7.4, 10.5±9.6, 3.9±3.8 and 2.0±2.7 to 10.5±8.0, 15.1±10.6, 16.3±13.6, 6.5±7.3 and 2.5±3.0, respectively. Conclusions: EYE FINE offers the advantage of auto-focusing according to working distance.
