The main tool used by eye surgeons in Lasik Surgery, the excimer laser has proved to be a great help to those who experience eye problems and want to find a more long-term solution. Skilled and well trained eye surgeons are able to help you correct your vision with the use of the laser and make sure that you are satisfied with the results. Despite there being a variety of manufacturers of the excimer lasers that eye surgeons use, all of them are generally the same and can help you whether you suffer from farsightedness, nearsightedness, or astigmatism.
However, it is important to note that there are different ablation patterns found in the lasers. Ablation refers to the process done by the surgeon to reshape the patient’s cornea with the use of the excimer laser. This variety in ablation patterns results in different procedures and approaches to reshaping the cornea of the patient. There are three different ablation patterns used in lasik surgery and these are conventional, wavefront guided, and wavefront optimized. Today, we are going to take a closer look into these different ablation patterns and learn how they work in the reshaping or ablation of a person’s cornea to correct his vision.
1.) Conventional – Being the most common ablation pattern in lasik surgery, conventional ablation patterns are found in majority of the excimer lasers being manufactured today. There are parameters that the eye surgeon must stick to in order to ensure the safety of the patient and the treatment process is based off the prescription of the patient. Majority of eye complications can be treated through this ablation pattern in Lasik Surgery but there is also a risk of the patient developing side effects like the appearance of halos or glare in one’s vision.
2.) Wavefront guided – This ablation pattern is also known as custom lasik or wavefront lasik. Similar to the conventional ablation pattern the process of wavefront lasik bases on the prescription of the patient. The great thing about wavefront lasik is that it can be used to treat specific problems that the patient is suffering from which is why it is also known as custom lasik. Because of how it targets specific problems without affecting other areas of the cornea, patients who undergo wavefront lasik have a smaller chance of developing any negative side effects.
3.) Wavefront optimized – This type of ablation pattern is found in wavelight lasers. The surgeon also bases the treatment process on your prescription but he also takes into account how thick and how curved your cornea is. With that data, the laser can be adjusted to hit the cornea in a specific way. The great thing about wavefront optimized ablation patterns is that it can be used to treat the negative side effects which have resulted in other eye surgery procedures.
Now that you know about the three ablation patterns used in Lasik Surgery you can have a better idea of the process of going through eye surgery if you ever find yourself needing laser eye surgery.
