WebIn several large studies on cataract surgery alone, a refractive result within ±0.5 diopters was found in 72–74% of cases. 5,6 In contrast to these results, there is a still a level of uncertainty regarding refractive results of combined cataract and vitrectomy. Several studies prospectively compared Phaco-Vit to standard phaco surgery and ... WebThese visual distortions are explained by the refraction of light. In this case, the light rays that undergo a deviation from their original path are those that travel from the submerged portion of the pencil, through the water, across the boundary, into the air, and ultimately to the eye. At the boundary, this ray refracts.
