Objective To compare the effectiveness of the newly designed continuous-focus electronic low vision aids with optical low vision aids in low vision rehabilitation.Methods In a prospective case-control study,19 low vision patients and 14 blind patients used the optical low vision aids and the newly designed continuous-focus electronic low vision aids,respectively,while testing near visual acuity and reading newspapers.Near visual acuity,reading speed and reading duration were recorded and compared using a paired t test.Results The difference in near visual acuity was significant (t=-2.392,P＜0.05) for all patients when optical low vision aids were compared to near continuous-focus electronic aids.For blind patients and low vision patients,the difference in near visual acuity was also significant (t=-7.433,-8.721,P＜0.01).The difference in reading speed was significant (t=-4.290,-6.728,P＜0.01) for all patients and blind patients when using optical low vision aids and near continuous-focus electronic low vision aids.The difference was not statistically significant for low vision patients alone (t=-1.534,P＞0.05).For all patients,whether blind or low vision patients,the difference in reading duration was statistically significant (t=-8.211,-6.137,-6.007,P＜0.01) when using the optical low vision aids and near continuous-focus electronic low vision aids.Conclusion The newly designed continuous-focus electronic low vision aid is more effective in improving patients' near visual acuity and reading ability.
