Traditional LASIK
The traditional LASIK is a no suture procedure that uses a three-step process to correct refractive error. First, a flap is created in the outer cornea with a tool called a microkeratome, which is a very small surgical blade, to separate a thin top layer of the cornea. Second, an excimer laser is used to re-shape the inner corneal tissue to individual needs. Finally, the flap created in the first step is then placed back down on to the cornea.
IntraLASIK (IntraLase)
This is a procedure for mild to moderate degrees of nearsightedness or low degrees of farsightedness and/or astigmatism. It is an all-laser LASIK procedure where no surgical blade is used on the eye. Instead of using a microkeratome to create the flap, IntraLASIK uses a laser for the first step as well as the laser in the second step to re-shape the cornea. The major advantage of IntraLASIK over the traditional LASIK is a more clean and precise cut that reduces chances of post-operative complications such as corneal haze.
Advanced Surface Ablation (ASA)
This is a safe alternative for patients who do not fit the criteria for IntraLASIK or traditional LASIK. It is an excellent option for moderately to severe nearsightedness and for those individuals who have corneas too thin or irregular for LASIK options. This may also be a good choice for cases where a corneal flap would not be recommended such as for extreme contact sports, military aviation, or severe dry eyes. A flap is not created on the cornea as with LASIK procedures. The corneal surface is treated directly with an excimer laser. A bandage contact lens is placed on the eye and removed after 4-5 days which will allow the surface cells to reform creating a strong refractive system. The healing time is longer than LASIK procedures and it is recommended to plan for around 4-5 days off from work after the procedure. There will be slightly more discomfort post-operatively than LASIK.
Conductive Keratoplasty (CK)
CK is a non-laser vision procedure specifically for people over 40 who have presbyopia and for farsighted individuals. Presbyopia is where the eyes begin to lose the ability to focus on near objects. If treating presbyopia, monovision would be an option where one eye is used for distance vision and the other eye is used for near activities. CK uses radiofrequency (RF) energy to heat and shrink tissue instead of laser energy to remove tissue. There is no cutting of tissue and the procedure only takes 3-5 minutes and is virtually painless. CK changes how the cornea focuses light by reshaping the corneal surface on the front of the eye. There may be some discomfort and light sensitivity for a few days. There also may be some gradual change over time back to the original shape of the cornea.
The Doctors at Owensboro Family Eye Care Center do not perform the actual surgical procedures above, but do perform the Consultations and Post-operative care for these procedures. We can help give you more information and recommend Laser Surgery Centers to you so that you can make the best informed decision about your eyes.
