Different Types of Lasik Eye Surgery based on Ablation Pattern

When it comes to lasik eye surgery, all procedures are similar in a way because the same type of laser, the excimer laser is used in the reshaping of the cornea or ablation. However, there are a number of different manufacturers of the excimer lasers which surgeons use. It doesn’t really matter what the manufacturer of the excimer laser is as long as the surgeon performing the lasik eye surgery is well trained and skilled, he can help treat any refractive error in people whether it is myopia, hyperopia, or astigmatism.

However, when we are talking about laser ablation patterns, then you can classify lasik eye surgery into different types. Today, we are going to talk about three different types of lasik eye surgery based on the laser ablation patterns that they follow. These three are conventional lasik treatment, wavefront-guided lasik treatment, and finally wavefront-optimized lasik treatment.

1.) Conventional lasik eye surgery – Among the three different types of lasik eye surgery, conventional lasik is the most common as it is the ablation pattern which can be found on most of the lasers available today. During conventional lasik eye surgery, the surgeon bases his treatment on the prescription glasses that the patient uses making sure to be within the fixed parameters which can be different between patients. Conventional lasik eye surgery can help treat most patients but the side effects are more likely with the patient getting halos, glare, or even have issues with seeing in the dark.

2.) Wavefront-guided lasik eye surgery – Wavefront-guided lasik eye surgery is also called custom lasik eye surgery or just wavefront lasik. Just like conventional lasik eye surgery, wavefront lasik bases its treatment through the patient’s glasses. However, wavefront-guide lasik eye can also treat any specific alterations called high order aberrations in the eye of the patient reducing any negative side effects. Before this type of lasik eye surgery can be performed, the surgeon has to perform mapping over the patient’s eye in order to see and identify any problem no matter how small it is. Once all problems have been identified, the surgeon can generate the map which will guide him during the surgical procedure.

3.) Wavefront-optimized lasik eye surgery – Wavefront-optimized lasik eye surgery is the type of surgery that is offered in wavelight lasers. This type of lasik eye surgery also bases its treatment of the prescription glasses of the patient but it also bases on the curvature and the thickness of the patient’s cornea. The laser is applied onto the cornea’s periphery in a special way. Wavefront-optimized lasik eye surgery has been found to be able to treat the aforementioned problems that patients can experience with conventional lasik eye surgery which are halos, glare, and problems with seeing at night.

So those are the three different types of lasik eye surgery based on the ablation pattern that is followed. All three are equally effective in treating problems of refractive error but with problems that are more specific, it would be best to go with either wavefront guided or wavefront optimized surgery.
