Different LASIK Procedures

Imagine living life without the need to wear glasses. Imagine not having to search for glasses or deal with contacts every morning. You can wear sunglasses that are prescription-free without the need to adjust them to your glasses. Laser eye surgery has made it possible to achieve these scenarios. The most common type of eye surgery, LASIK is a popular choice. It has been used for more than 10 years to eliminate the need for contact lenses and glasses. It was initially considered a rare procedure and people were skeptical when it became more popular. However, technology has improved greatly over the years so that consumers can see it as an option to enhance their vision. 

In recent years, vision specialists have achieved remarkable advances in refractive or laser eye surgery. There are many kinds of vision correction surgery. The majority of procedures aim to shape the cornea in a way that the light from the eye can focus onto the retina. Others replace the cornea. This article will help you understand some of the different types and procedures of LASIK.

LASIK eye surgery has become a the procedure for correcting many of the most common vision issues. This laser-assisted procedure is used to correct nearsightedness, astigmatism, and farsightedness. LASIK is a procedure that reshapes the corneal tissue in order to direct light towards the retina. The uniqueness of LASIK is in its method. To access the underside of the eye, eye surgeons make a flap from the outer layer of the cornea. This procedure is precise and computer imaging technology has allowed our LASIK Nashville experts to make detailed images of the cornea and help guide the treatment.

Wavefront LASIK is one of the most popular forms. It's also called Custom LASIK. This is the most advanced and modern type of LASIK. This procedure produces a 3D map of your cornea. The accuracy of this surgery means that you have a better chance to achieve 20/20 vision. This form of surgery can be performed using a wavefront analyzer, which allows doctors to take a 3-D image of each eye so that they understand the situation and are able to tailor their surgery to the individual patient. Many prefer this type of surgery because it is more accurate. Wavefront LASIK patients usually heal quickly. Patients often notice a significant improvement in their vision within a few days.

PRK (photorefractive Keratectomy) is a procedure which uses a laser in order to shape the cornea. PRK lost some popularity when LASIK was invented, but it has seen a slight revival in recent years. For certain patients, many doctors prefer PRK over LASIK. PRK does not reshape the cornea like LASIK. This procedure is ideal for people with mild-to-moderate nearsightedness, astigmatism, and farsightedness. PRK is also compatible with computer imaging technology. PRK patients usually need longer recovery times. The patient will see a temporary decrease in their vision, but it will improve over time.

LASEK can be used as an alternative to LASIK. It's a great option for those with thin corneas that are not suitable for LASIK. For people with thinner corneas, LASEK (Laser epithelial Keratomileusis), is another variant of LASIK. Your LASIK Nashville surgeon will not use a blade to do the procedure. Instead, LASEK works by reshaping the cornea using an excimer laser.This procedure will cause light entering the eye to focus onto the retina for clearer vision. LASEK recovery is faster than Wavefront or Custom LASIK.

All-Laser LASIK offers the best way to perform LASIK. Instead of using a blade to create the corneal flap, the All-Laser LASIK uses a laser. This is a crucial part of all LASIK procedures. The procedure proceeds in the same way as Custom LASIK, except that the flap was created using a second laser instead of a blade. Patients with nearsightedness or farsightedness can use this type of LASIK. This Bladeless technology makes it possible to customize the size of each flap according to the patient's needs. Lasers create smoother edges, which speeds up the healing process. Traditional LASIK uses a tiny blade to make the flap. Blade-technology restricts the surgeon's ability customize the size of the flap, and can lead to a potential mechanical problem or error during treatment.

Similar  to PRK, the EpiLASIK procedure looks very much like it. A thin corneal layer is separated by the doctor and then it's reshaped. This layer can be either removed or replaced. After the surgery is completed, the doctor will apply a soft contact lens that protects the affected area.

Topography-guided LASIK is a specialized vision treatment for nearsightedness and astigmatism. This laser treatment procedure is customized to match the unique surface shape of the patient’s eye. Topography-guided LASIK uses wavefront optimization that  will shape of the cornea to prevent side effects such as glare and halos at night. Topography-guided LASIK may also be an effective option for those who have abnormal corneal surfaces who may not be candidates for other types of LASIK procedures.

As  with any surgery, the first step is to attend your complimentary, thorough LASIK exam at LASIK Nashville. The exam is similar to any previous eye exam, but will include additional testing for laser vision surgery. We will be able to determine many things, including the health and condition of your eyes, the pupil diameter and corneal thickness, as well as your corneal topography. This is similar to a fingerprint for your eye because no topography is exactly the same. Your lifestyle and hobbies will be asked by our doctor. These insights will allow us to determine the most effective treatment for you.
