Cataract Extraction

Overview

cataract-overview3.webp

Cataract extraction is a surgical procedure performed to remove a cloudy lens from the eye (the cataract) and typically replace it with an artificial intraocular lens (IOL).

Cataracts often develop as a natural part of aging but can also result from various factors, including genetics, certain medications, and other medical conditions.

How is Cataract Extraction done?

Preoperative Assessment:
  • Comprehensive eye examination by an ophthalmologist to assess the cataract's severity and evaluate the overall eye health.
  • Measurement of the eye’s dimensions (e.g., axial length) to determine the appropriate IOL power.
Medical History:
  • Review of the patient's medical history, including any current medications, allergies, and previous eye surgeries.
Testing:
  • Vision tests, eye pressure measurement, and possibly imaging tests to evaluate the eye's structure.
Patient Education:
  • Discussion of the procedure, potential risks, benefits, and the type of anesthesia used.
  • Instructions on medication management (e.g., stopping certain blood thinners).
Day of Surgery:
  • The patient may be instructed not to eat or drink for a specific period before the surgery.
  • Arrangements for transportation post-surgery, as vision will be temporarily impaired.

Anesthesia:
  • Local anesthesia is typically administered to numb the eye, often accompanied by sedation to help the patient relax.
Incision:
  • A small incision (about 2-3 mm) is made at the edge of the cornea.
Phacoemulsification:
  • The most common technique where an ultrasonic device breaks up the cloudy lens into small pieces, which are then suctioned out.
IOL Placement:
  • An intraocular lens is inserted through the same incision. The lens may be foldable, allowing it to be inserted through a smaller opening.
Closure:
  • The incision typically does not require stitches, as it is self-sealing.
Postoperative Care:
  • The patient may receive antibiotic and anti-inflammatory eye drops to prevent infection and reduce swelling.

While cataract extraction is generally safe, potential complications include:
  • Infection (Endophthalmitis): Rare but serious inflammation inside the eye.
  • Bleeding: Can occur during or after surgery.
  • Retinal Detachment: Separation of the retina from the back of the eye.
  • Cystoid Macular Edema: Swelling of the central retina.
  • Incorrect IOL Power: May necessitate additional surgery.
  • Postoperative Pain: Discomfort may occur, typically managed with medication.

Various IOL options are available, including monofocal, multifocal, and toric lenses. The choice depends on the patient's needs and preferences.

Vision improvement is often noticed within a few hours, but it may take a few days for vision to stabilize.
