Comparison of Anterior Corneal Astigmatism with Total Refractive Astigmatism
, 2023 The relation between anterior corneal astigmatism and total refractive astigmatism is poorly defined in India. The prevalence of astigmatism in especially young patients and those un-co-operative adult patients is a topic of interest and big challenge for an optometrist to correct it properly from avoiding refractive amblyopia in young patients as well
