This procedure is ideal for people that are farsighted, myopic, or have astigmatism. What makes LASIK distinct is its method. Eye doctors create a flap of the outdoor layer of the cornea in order to access the underlying cells. The treatment requires accuracy, as well as developments in computer system imaging technology, let LASIK experts produce comprehensive corneal images, as well as direct the therapy.

PRK is a treatment that utilizes a laser for reshaping the cornea. Unlike LASIK, PRK just improves the surface area of the cornea. It’s ideal for moderate to modest farsightedness, astigmatism, or nearsightedness. PRK also can collaborate with computer imaging technology.
- Laser epithelial keratomileusis or LASEK
This process is a slight difference from PRK. The medical professional is going to make a flap at the place epithelial cells get loosened up by utilizing an alcohol solution. And then, a laser reshapes the cornea and the flap is set as well as secured with a soft contact lens to ensure that it can recover around the improvement. LASEK treats farsightedness, nearsightedness, as well as astigmatism.

No laser gets utilized, and instead, the physician makes a cut in the sub-layer of the cornea to reshape and deal with vision.
The EpiLasik procedure is similar to PRK. The medical professional divides a thin layer of the cornea, and then, improves it. The layer may either be replaced or removed. The doctor completes the procedure by applying a soft contact lens to secure the area up until it can totally heal.
