A cataract forms when proteins in your eye’s natural lens break down and clump together, and this clouding usually develops slowly over many years. Colors may look faded, and night driving may grow harder. To solve this, cataract surgery treats the problem by removing the cloudy lens and placing a clear artificial one. Here is more information about the procedure:
Removing Cloudy Lens
Your surgeon starts by numbing your eye with drops. You stay awake during the procedure, but you may receive a mild sedative. The sedative helps you relax while the surgical team works. Patients typically feel light pressure but no sharp pain during cataract surgery.
The surgeon makes a tiny incision at the edge of the cornea, and the opening often seals without stitches. Next, the surgeon opens the thin capsule that holds your lens. This clear capsule stays in place to support the new lens.
Most surgeons use a method called phacoemulsification, which breaks the lens into small pieces with ultrasound. A small probe then suctions the fragments out of your eye. Some clinics use a laser for certain steps, and others rely on handheld tools. Both approaches remove the full cloudy lens.
Replacing With an Artificial Lens
Doctors call the new lens an intraocular lens, or IOL. The surgeon folds the IOL so it fits through the small incision. The lens unfolds inside the capsule, and it stays there permanently. Your surgeon will measure your eye so the lens power matches your vision needs. Your options typically include these lens types:
- Single focus point: Sharpen vision at a single distance, usually far away. Many people still need reading glasses afterward.
- Multiple distances: Help you see clearly up close, at arm’s length, and far away, so you may rely less on glasses.
- Astigmatism-related lenses: Correct an uneven curve in the cornea for crisper, clearer vision.
- Smooth range of vision: Gives you continuous focus from far to middle distances, which suits everyday tasks like driving and computer work.
Taking About 10 Minutes
While the lens removal and replacement take about 10 minutes, your full visit lasts longer. Staff check your vital signs before surgery, and they monitor you afterward. Plan to spend several hours at the surgery center. Arrive early to complete paperwork and receive dilating drops.
Doctors treat one eye at a time. The second eye surgery typically follows a few weeks later, and this gap lets the first eye heal. You will need a ride home because the sedative and eye drops affect your vision.
Restoring Vision
Some people notice clearer sight within a day, but others see changes over several weeks. Blurry vision and mild itching are typical at first. Your doctor will schedule follow-up visits so they can track your healing. Recovery steps may include the following:
- Use prescribed eye drops on schedule
- Wear a protective shield while sleeping for about a week
- Avoid rubbing or pressing on your eye
- Skip heavy lifting and swimming until your doctor clears you
If you notice sudden pain, flashes of light, or a shadow over your vision, call your surgeon right away. These signs are rare, but they need prompt attention. Some people develop a cloudy capsule months or years later. Doctors treat this condition with a quick laser procedure.
Book a Cataract Surgery Consultation
A consultation starts with a full eye exam. The doctor checks whether a cataract explains symptoms like glare or blurry sight. Bring a list of your medications, and ask about insurance coverage and payment options. Contact an eye specialist to schedule a visit if cataract symptoms affect your daily routine.
