Nuclear sclerosis cataracts in older adults typically cause which refractive change?

Explanation:
Nuclear sclerosis changes the lens by making its nucleus denser and increasing its refractive index, which raises the lens’s optical power. That extra power pulls the focal point forward, producing a myopic (nearsighted) shift in refraction as the cataract progresses. Some patients may notice temporary improvement in near vision due to this shift before the opacity worsens. A hyperopic shift would mean farsightedness, which isn’t the typical direction for this type of cataract, and a cylindrical shift would imply astigmatism rather than a uniform change in spherical power.
