Cataract surgery is a common procedure that can sometimes result in a noticeable change in eye color. This change is usually due to the replacement of the eye’s natural lens with an artificial intraocular lens (IOL), which can slightly alter the way light reflects off the eye. While this change is typically subtle, it can […]
Why are colors brighter after cataract surgery?
Cataract surgery often results in significantly brighter colors and sharper vision. This transformation occurs because the surgery removes the cloudy lens, replacing it with a clear, artificial one. The cloudiness caused by cataracts filters and dulls colors, so removing it allows colors to appear more vivid and true to life. What Causes Colors to Appear […]
