3D Lasik Eye Surgery Animation
Educational only: videos on MedicalVideos.com are for general information and are not medical advice. Always consult your own doctor about your health.
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 3D animation explains LASIK, a laser procedure that reshapes the cornea to reduce dependence on glasses or contact lenses. It outlines the main stages shown, from placing a suction ring and cutting a corneal flap with a microkeratome to reshaping the inner cornea with an excimer laser and returning the flap.
Key points
- Explains LASIK for myopia, hyperopia and astigmatism as presented in the animation
- Shows a suction ring and microkeratome used to create a corneal flap
- Shows excimer laser reshaping of the exposed cornea
- Shows the corneal flap returned to position
Video Transcript
This 3D animation explains LASIK eye surgery, a laser procedure intended to reduce dependence on glasses or contact lenses by reshaping the cornea so light focuses on the retina. The narration walks through the steps: a suction ring stabilises the eye, a microkeratome cuts a corneal flap, an excimer laser reshapes the exposed inner cornea, and the flap is returned to position. It notes the procedure is done as an outpatient with the patient awake, sometimes with a mild oral sedative.

LASIK or laser assisted in situ keratomelusas 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 or nearsightedness but can also be used to cure hyperopia, farsightedness or astigmatism, corneal irregularity. 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 eczema 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 sedatives.
