This 3D medical animation depicts the phacoemulsification and extracapsular removal of a cloudy lens, and the placement of an artificial lens.

The lens of the eye is responsible for focusing images onto the back of the eye. It is normally transparent. As a normal part of aging, the lens begins to cloud and causes a gradual, painless loss in vision. Cataract removal is most often performed to better examine the back of the eye when monitoring for damage from certain diseases such as diabetes or glaucoma and to improve vision. There are two main types of cataract removal. The large majority of cataract surgeries are performed using the phacoemulsification technique. During the phacoemulsification technique an ultrasound probe breaks the cloudy lens into tiny fragments. The fragments are vacuumed out through a tiny incision. An intraocular lens implant is then inserted to replace the natural lens that was removed. Because the incision is tiny, stitches are often not necessary and visual improvement is usually noted relatively soon after surgery. During the extracapsular technique the cataract is removed as one entire piece. This requires a larger incision and stitches. An intraocular lens implant (artificial lens) is inserted to replace the natural lens that was removed. Recovery is usually slower, due to the larger incision. The stitches sometimes need to be removed, which is usually done in the office. After both procedures, the surgeon usually places a patch over the eye. ANCE00193

LASIK or Laser-Assisted In Situ Keratomileusis is a surgical procedure intended to reduce a person’s dependency on glasses or contact lenses.

LASIK surgery is most commonly performed as a cure for myopia (nearsightedness), but can also be used to cure hyperopia (farsightedness) or astigmatism (corneal irregularities).

LASIK is a procedure that permanently changes the shape of the cornea using a special laser and thus focusing the light rays exactly on the retina.

The steps of the procedure are as follows:

A suction ring is placed on the eye to stabilize and check the eye pressure.

The microkeratome, a cutting instrument, is attached to the suction ring.

The blade of the microkeratome is used to cut a flap in the cornea.

The exposed inner layer of the cornea is then reshaped with an excimer laser.

The corneal flap is returned to its original position.

LASIK is an ambulatory procedure; the patient can walk into the surgery center, have the procedure and walk out again and is awake the whole time. Occasionally, the doctor may administer a mild oral sedative.

This medical animation depicts a LASIK procedure to correct near sightedness (myopia) of the eye. LASIK stands for laser-assisted in situ keratomileusis and is a procedure that permanently changes the shape of the cornea, the clear covering over the front of the eye.
