LASIK (Laser-Assisted-In-Situ Keratomileusis) is currently one of the most frequently performed elective procedures in North America. It is a highly effective outpatient procedure that is suitable for most low, moderate and higher prescriptions. LASIK uses a cool beam of light from the excimer laser to gently reshape the front surface (cornea) of your eye.

The LASIK Procedure

1. Anesthetic drops are applied to the eye.

2. A protective flap is created and gently lifted by the surgeon, revealing the inner corneal tissue.

3. Computer-controlled pulses of cool laser light are applied to the inner layers of your cornea. As the laser pulses, it makes a ticking sound. The inner corneal layer is reshaped with the laser to mimic your contact lens or glasses prescription.

4. The surgeon gently replaces the flap and aligns it to its original position. It heals naturally and securely.

5. Some patients may feel slight irritation for a few hours, but most are quite comfortable after a nap and rest.

What is Bladeless LASIK?
In the LASIK procedures, a flap of corneal tissue must be created and then folded back. The cornea is the transparent dome-like structure that covers the iris and pupil of your eye. By creating a flap in the cornea, the surgeon is able to perform the laser vision correction treatment on the inner layer of the cornea and allows for a rapid visual recovery.

With Bladeless LASIK, the surgeon uses a laser (1)  to create the corneal flap. This technology enables the surgeon the ability to customize the corneal flap for every individual patient. In recent studies done by IntraLase, this technology may now make it possible to treat those who were previously dismissed as non candidates due to thin corneas.

· Studies have shown the incidence of dry eye symptoms may be reduced with Bladeless LASIK.

· With Bladeless LASIK and its customization components, surgeons can treat a wider variety of patients, including patients with thin corneas.

· Bladeless LASIK has been used in more than one million LASIK procedures worldwide.

In cataract surgery, the cloudy natural lens must be removed from the eye.

What Happens During Cataract Surgery?

Cataract surgery usually is done on an outpatient basis. You may be asked to skip breakfast and avoid drinking liquids, depending on the time of your surgery. Also, do not wear eye makeup on the day of surgery. Upon arrival at the facility, you will be given eye drops to dilate your pupils and perhaps a sedative to help you relax. A local or topical anesthetic will make the operation painless.

The skin around your eye will be thoroughly cleansed, and sterile coverings will be placed around your eye and head.

Under an operating microscope, at least one small incision is made into the eye. The surgeon will then remove your cloudy lens (the cataract).

This procedure can be performed using an ultrasound-driven instrument that "sonically" breaks up the cataract (phacoemulsification) as it is suctioned (aspirated) out of the eye.

In another surgical method, special instruments are used to mechanically break up the cloudy lens into small pieces (phacofracture) and remove them directly from the eye through a small incision.

The surgeon will insert a plastic or silicone IOL inside the eye to replace the natural lens that was removed.

Most incisions used for cataract surgery are self-sealing. However, on occasion, incisions may need to be sutured. When stitches are used, they rarely need to be removed.

When the operation is over, the surgeon will usually place a protective shield over your eye. After a short stay in the outpatient recovery area, you will be ready to go home. Plan to have someone else drive you home.

Phacoemulsification in cataract surgery involves insertion of a tiny, hollowed tip that uses high frequency (ultrasonic) vibrations to "break up" the eye's cloudy lens (cataract). The same tip is used to suction out the lens.

After the eye's natural lens is removed during cataract surgery, an artificial or intraocular lens is implanted to take its place.
