The actual LASIK procedure process is performed the same way in both conventional LASIK and Custom LASIK. Conventional LASIK is still an excellent choice for many patients. Your doctor will recommend which procedure is best for you based on your visual aberrations; they will help you to determine if you could benefit from the higher level of customization that Custom LASIK may provide.
Custom LASIK is necessary for some and desirable for many. Everyone's eyes are different; your pre-procedure consultation with your doctor will help determine the range of your probable outcome based on your particular prescription, healing profile and expectations. Your TLC affiliated eye care professional will help you make the best choice for you.
