Objective: Prospective study to evaluate the effectivity and acceptance of optical low vision aids.
Materials and Methods: This is a prospective study which included 50 patients with low vision satisfying
the inclusion criteria. The cases were divided in to 3 groups less than 20 years (group1), 20 to 60 years
(group2) and more than 60 years (group 3). These patients were counseled and trained to us e the low
vision aids in our low vision aid clinic. They were followed up for 6 months regularly and during follow
up the reason for acceptance and non acceptance of these devices were found out.
Results: In this study patients with better contrast sensitivity greater than or equal to 0.3 on Pelli-Robson
contrast sensitivity chart had better acceptance (p value 0.0 23). Younger patients less than 20 years of age
have good acceptance for both near vision aids & distance vision aids when compared to elder patients
more than 60 years of age who had good acceptance for near vision aids and poor acceptance for distance
vision aids (with p value of 0.001). Taking Initial best corrected visual acuity (BCVA) in to account it was
seen that patients falling under economic blindness group had better acceptance (p value 0.042).
Conclusion: Prescription of low vision aids (LVA), adequate training and addressing the comorbidities can
improve the acceptance level. Similarly economic blindness group more readily accepted the low vision
aids since it helped their academic and professional development. Patients with better contrast sensitivity
had better acceptance. Addressing the expectation by proper counselling before prescripti on of low vision
aids is a must.
