Perception of Trifocal IOL Performance in Young Adults with High Astigmatism and Hyperopia and its Improvement Using Small Incision Lenticule Extraction

Hyperopia is a kind of refractive error in which incoming light is focused behind, instead of on, the retina wall due to insufficient accommodation by the lens. It is likely affected by ethnicity, geography, and a family history of hyperopia or accommodative esotropia and is categorized as low ( 64 2.00D), moderate (2.00-4.00 D), and high (> 4.00D). Beyond hyperopia refractive error, patients may have poor accommodative function or visual perceptual skills
