A Look Into Topography-Guided LASIK Procedure

Any person in the world wants to have a normal, 20/20 vision. However, not everyone is lucky enough to have such. Thus, there are people who wear eyeglasses and/or contact lenses so that they will be able to see clearly. The good thing is that people can already choose not to wear such corrective apparatuses. That is due to the fact that in 1988, the so-called laser vision treatment has been introduced. Additionally, such procedure has evolved and improved as time went by. Through such, the Laser-Assisted In-situ Keratomileusis or LASIK has been introduced. Generally speaking, it is a procedure wherein the qualified doctor will change the shape of the patient’s cornea using laser. Since such has been effective and highly accepted, more technological improvements have been made.


In fact, in the year 2013, the U.S. Food and Drug Administration (FDA) approved a new addition to the LASIK family. Such is the so-called Topography Guided LASIK. As an overview, the approval has been given because of the good results that have been determined by a 12-month study or research. According to the research’s data, 64.8% of patients who underwent the procedure experienced 20/16 vision or better, 34.4% experienced 20/12.5 vision, and 6% returned to their 20/20 vision. Likewise, the procedure has also shown that it is 30% better in correcting the eye problem than using glasses and/or contact lenses. In addition to such improvements, the occurrence of the common post-LASIK complications has also been reduced. Meaning, lesser patients experienced light sensitivities, glaring, and reading and driving difficulties.


Apart from the advantages of topography-guided LASIK that has been pulled out from the research, many ophthalmologists also love the fact that they are able to clearly customize the patient’s treatment. That is due to the fact that the method is highly accurate when it comes to measuring the whole eye and the corneal structure. Likewise, the measurement obtained is also very detailed in nature. In addition, besides near sightedness, the procedure has also shown to be helpful to individuals who have astigmatism. Nevertheless, people who are interested in undergoing the procedure should make sure that they consult a certified and licensed ophthalmologist. They should remember that such is still considered as a surgical procedure. Thus, it requires special skills and training.


In addition, interested individuals should also understand the fact that not everyone is recommended or qualified to undergo the TP-guided LASIK treatment procedure. People who have severe astigmatism or those who have less than or equal to -3 diopters of vision reading are examples of those who are not qualified. On the other hand, qualified patients should have less than -8 dioptesr near sightedness levels. They should also have a combined astigmatism and near sightedness reading of less than -9 diopters. As similar to any other LASIK procedure qualifications, the near sightedness or astigmatism readings should not have changed over a period of one year. Likewise, there should also have not been any changes in the eye prescription. Similarly, the patients should be generally healthy. In addition, they should also be 18 years old and above and are not experiencing any eye dryness.
