What is a cataract and when should it be operated? A clear guide for patients

Short answer: a cataract is the clouding of the crystalline lens, the eye’s natural lens. It is operated when it interferes with your daily activities — there is no need to wait for it to “ripen.” Modern surgery takes about 20–30 minutes, is outpatient, and lets you regain sharp vision within days.

What exactly is a cataract?

Inside the eye we have a natural lens called the crystalline lens. Over the years (and faster with diabetes, intense sun or certain medications), that lens gradually clouds like a fogged-up window. That is a cataract. It is not a film that can be removed with drops or an external laser, and it cannot be corrected with glasses.

Signs you may have a cataract

• Blurry or cloudy vision, even when you change glasses
• Colors look dull or yellowed
• Car headlights glare at night
• You need more and more light to read

The myth of “waiting for it to ripen”

Decades ago, doctors waited until the cataract was very advanced. Today it is the opposite: operating in time makes surgery safer and recovery faster. A very “ripe” cataract is harder, requires more ultrasound energy, and raises the risk of complications.

The practical rule: surgery is done when the cataract interferes with your life — driving, reading, working or seeing your family’s faces.

What is modern surgery like?

Today’s technique is called phacoemulsification: through an incision under 3 mm, the clouded lens is dissolved and removed with ultrasound, and an intraocular lens custom-calculated for your eye is implanted. With premium lenses, your distance and near vision can be corrected too.

• Eye-drop local anesthesia
• 20 to 30 minutes, no hospital stay
• Visual improvement from the first 24–48 hours

The next step

The diagnosis is confirmed at a comprehensive eye exam with dilated pupils, where the exact lens your eye needs is also calculated. Book your appointment on WhatsApp at 998 601 8740 with Dr. Fabiola Flores in Cancún.
