| Preoperative imaging | Biometry for IOL sizing is essential | Topography/topography-based planning required |
What is Cataract?
Cataract is a condition where the eye's natural lens becomes cloudy, reducing clarity and contrast. It typically develops with age and can affect one or both eyes, making everyday tasks harder, especially in bright light or at night.
Management depends on the impact on daily life and systemic health. Cataract surgery is the definitive treatment to restore clear vision, with choice of IOL influencing postoperative spectacle needs; decisions are made after comprehensive eye assessments.
