Pre-operative tests and procedures performed before LASIK eye surgery

You’ll need a complete eye examination by your refractive surgeon. Your eye care professional may perform a preliminary eye exam. Take your eye prescription records with you to the exams. If you wear contact lenses, stop wearing them before your baseline evaluation. Your doctor should do following some constraints they are dilate your pupils to fine-tune your prescription, examine your eyes to make sure they’re healthy, testing for glaucoma, performing a retinal exam, Assessing for dry eye, Ask you to sign an informed consent form after a thorough discussion of the risks, benefits, options, and possible complications of laser eye surgery. You take a quick review of the form carefully, and don’t sign until you understand everything in the form. If you qualify for surgery, your doctor may tell you to stop wearing your contact lenses for a while before the surgery. This is done because use of contact lenses can temporarily change the shape of the cornea since your cornea should be in its natural shape the day of surgery. Your doctor also may tell you to stop wearing makeup, lotions, or perfume for a few days before surgery. These products can interfere with the laser treatment or increase the risk of infection after surgery.

Advanced surgical procedures by our experts in LASIK eye surgery

eye surgery

LASIK is performed in an outpatient surgical setting, with the patient reclining under a surgical device called an excimer laser. Initially your eye is made numb with a few drops of topical anesthetic. An eyelid holder, called a speculum, is placed between the eyelids to keep them open and prevent you from blinking. A suction ring placed on your eye, lifts and flattens the cornea and prevents your eye from moving. You may feel pressure from the eyelid holder and suction ring. Vision appears dim or goes black from the time suction ring is placed on your eye until it is removed. Then surgeons creates hinged flap of corneal tissue using an automated micro surgical device like laser or microkeratome blade. The corneal flap is lifted and folded back. The excimer laser that has been programmed with measurements specifically for your eye is then centered above your eye. You will look at a special pinpoint of light that is known to be target light and the laser sculpts the exposed corneal tissue. After the laser has reshaped your cornea, the surgeon replaces the flap in position and smoothens the edges without placing any stitches. Your corneal flap will never adhere to the surface of the eye with quite the same strength it did prior to the surgery, so there is a rare risk of the flap becoming displaced with sufficient force.The laser reshapes the underlying corneal tissue, and the surgeon replaces the flap, that quickly adheres to the eyeball. There are no stitches included in this surgery. A shield that is either clear plastic or perforated metal is placed over the eye to protect the flap.
