The process of Lasik Surgery is aimed at correcting people’s vision. You might not know but there are different procedures when it comes to lasik eye surgery due to the fact that they all use the same type of laser known as an excimer laser in the ablation process which reshapes the person’s cornea. However, it is important to note that there are different manufacturers of excimer lasers and different eye surgeons may use different brands. But the brand of the excimer laser doesn’t really matter as long as you go to a skilled and knowledgeable eye surgeon who can help you whether you have hyperopia, myopia, astigmatism.
The difference between the procedures of lasik eye surgery lies in the laser ablation patterns used by the eye surgeon. Based on that, you can factor lasik eye surgery into three different types which are conventional lasik eye surgery, wavefront-guided lasik treatment, and wavefront-optimized lasik treatment. Today, we are going to take a closer look into these three types and learn how differently the eye surgeon can correct our vision with the excimer laser.
1.) Conventional lasik eye surgery – Being the most common type of lasik eye surgery, conventional lasik eye surgeries follow an ablation pattern which is available in most of the excimer lasers manufactured today. In this type of lasik eye surgery the surgeon always bases the treatment on the prescription of the patient and the surgeon must make sure to stay within the fixed parameters to ensure safety. Take note that these parameters can vary between patients. Conventional Lasik Surgery is great as in can treat most patients. The downsides are the side effects which are the appearance of halos, glare, and even problems in nighttime vision.
2.) Wavefront-guided lasik treatment – Also known as wavefront lasik or custom lasik eye surgery, this type of eye surgery is similar to conventional eye surgery due to the fact that eye surgeons also have to base the treatment on the patient’s prescription. The difference is that wavefront lasik can help treat any specific complications which are also known as high order aberrations which may affect the patient’s eye. It is because of this that the negative side effects are significantly reduced. Prior to beginning, the surgeon will have to map the patient’s eyes allowing him to identifying all complications there are which need to be treated.
3.) Wavefront optimized lasik treatment – The type of surgery which is performed when the surgeon uses wavelight lasers, wavefront optimized lasik treatments also are based on the prescription of the patient. However, the eye surgeon also takes into account the thickness and curvature of the patient’s cornea. With the optimization of the treatment, the laser hits in the patient’s cornea in a more efficient way. Because of this, wavefront optimized Lasik Surgery can treat any negative side effects of other eye surgeries.
So those are the three main types of lasik eye surgery. Now that you have a better idea of them, you will know what you are getting into if ever you find yourself in need of eye surgery.
