What is cataract?
Cataract is the clouding of the natural lens inside the eye. As the lens loses transparency, vision may become blurred, dimmer or more sensitive to glare.

Cataract may reduce sharpness, contrast and color perception.

At night, glare from headlights and bright lights may become more noticeable.
Symptoms that deserve evaluation
- Blurred, cloudy or faded vision
- Increased glare, especially when driving at night
- Need for stronger lighting to read
- Frequent changes in glasses prescription
- Temporary improvement in near vision in some cases
When should cataract be operated?
There is no single cataract grade that automatically requires surgery. The indication is based on how much cataract affects daily life and whether surgery is expected to improve visual function safely.
How surgery works
Modern cataract surgery removes the cloudy natural lens and replaces it with an intraocular lens. The procedure is usually performed under local anesthesia, with postoperative drops and follow-up visits.

Intraocular lenses
Lens choice is part of the surgical plan. Monofocal, toric, EDOF and multifocal lenses have different goals and tradeoffs. The best choice depends on anatomy, retina, cornea, lifestyle and expectations.

Recovery and risks
Most patients resume light activities progressively, but recovery varies. Cataract surgery is highly standardized, but no surgery is risk-free. Infection, inflammation, retinal problems, pressure changes and refractive surprises are uncommon but relevant possibilities.
When to seek evaluation
Schedule an evaluation if vision is interfering with reading, driving, work, hobbies or safety. Examination is the only way to confirm whether cataract is the main cause.
