What does cataract surgery entail?

Modern cataract surgery is one of the safest and most successful forms of surgery. It requires a very short hospital stay and is generally performed under local or topical anesthesia. The patient is awake during surgery but does not feel any discomfort or pain. Patients are ambulatory immediately after surgery and are discharged on the same day.

Cataract surgery at The Himalayan Eye Center is performed with sophisticated operating microscopes. A micro incision of 1.8 to 2.8 mm is first made in the eyeball (Step 1). A smooth round opening is then made in the front part of the lens capsule, which is a thin membrane enclosing the entire lens (Step 2). All cloudy lens material within the lens capsule is then removed through the same incision by the procedure of phacoemulsification using a thin titanium probe that emits high-speed ultrasound waves, vibrating at 40,000 times per second. This breaks the cataract into tiny pieces, which are then suctioned out of the eye through the same probe (Step 3). In the final step, a Foldable Intraocular Lens (IOL) is introduced through the small incision, and placed within the capsule of the lens where it unfolds and stays in place securely (Step 4).

Micro incisions such as those used in phacoemulsification seal themselves immediately after surgery and heal very quickly and allow one to return to normal work and activities within a few days. This is currently the most effective method for removing cataracts. The Himalayan Eye Institute has latest state-of-the-art Infiniti Vision System from Alcon, USA for cataract surgery.
