We Take Advanced Measures to Minimize LASIK Risks
Before undergoing LASIK eye surgery, it is important to completely understand LASIK risks. The doctors at our Toronto-area practices take great care to minimize these risks and provide the very safest care for our patients. Although complications are rare, fully understanding the risks associated with LASIK surgeries can allow you to make an informed decision about undergoing LASIK. If you have any questions or concerns about your LASIK procedure, and would like more information, please contact our office and make an appointment with one of our vision specialists.
The LASIK Procedure
LASIK corrects irregularities in the shape of the cornea, the dome-shaped front surface of the eye. The cornea is the point at which light enters the eye, and any imperfections in the shape of the cornea can result in nearsightedness, farsightedness, or astigmatism. Correcting these irregularities can reduce or completely eliminate the need to wear glasses or contact lenses. Your surgeon will use a special laser to create a small hinged flap in the epithelium, or outer layer of the cornea, to access to the inner layer, or stroma. Next, your surgeon will use an excimer laser to vaporize very small portions of the stroma, refining its shape. Finally, the flap is replaced to facilitate healing. Patients often experience an immediate improvement in vision.
Risks of LASIK
As with any surgery, there is a risk of complications and side effects that every LASIK patient should understand before their procedure:
- Undercorrection and overcorrection - If a surgeon refines too little or too much tissue during LASIK, the results can be less than satisfying. We use wavefront technology to create a highly detailed topographic map of your corneal surface, allowing us to calculate exactly the extent of treatment you require.
- Vision quality diminishing over time - Diminished quality of vision is an unavoidable effect of the natural aging process. LASIK can provide many years of enhanced vision, but it is important to understand that as you age, quality of vision will eventually decline.
- Astigmatism - Uneven tissue removal can cause astigmatism, or an asymmetrical corneal shape resulting in compromised vision. Our preliminary wavefront analysis reduces this risk dramatically.
- Glare, halos, and double vision - Also known as higher-order aberrations, these conditions are a common risk of LASIK surgery. Using a laser to create the corneal flap reduces this risk. Blades can result in flaps that are thin in the center, with thicker outer edges, which can cause glare and halos. Lasers are capable of creating much less invasive flaps, thus minimizing the risk of developing higher order aberrations as a result of LASIK. Wavefront analysis also plays an important role in minimizing this risk, because it provides the most comprehensive assessment of the patient's cornea.
- Dry eyes - LASIK procedures can cause a temporary reduction in tear production, which will cause your eyes to be drier than normal.
- Flap complications - Infections and inflammation at the flap site can cause complications, and the epithelial layer could heal abnormally. Using a laser instead of a blade to create the corneal flap minimizes the risk of flap complications.
You can minimize the risks of LASIK surgery by choosing a reputable, credentialed surgeon using sophisticated technology. Our doctors have an excellent track record of patient safety and satisfaction. We will conduct a thorough consultation to make certain that you are a good candidate for LASIK, and to determine if another surgery might be a better fit.
