Side effects of eye surgery laser - Risks of LASIK Procedures
Although the use of excimer laser in laser eye surgery has significantly improved patient outcomes, the procedure may also lead to laser-related side effects. The two main side effects associated with laser eye surgery laser are decentralization and irregular astigmatism.
Even with the use of different devices and decentralization may still occur. It is still open to the excimer laser to not hit the target accurately. Decentralization produces a range of symptoms, such aspoor vision, glare, halos and ghosting, to name a few. The symptoms are caused by light scattering at the edge of the area that was removed.
Some conditions have been noted to contribute to the onset of decentralization. These include the degree of myopia of the patient, the surgeon's experience and the specific position of the line of the patient's visual axis. In general, the more myopic a patient is, the less the patient's ability to focus on a light source,and the more likely it may be happening.
This can be diagnosed by using analysis of wavefront. The treatment includes the use of customized ablation of the cornea or the use of systems connected topography.
Irregular astigmatism
Another side effect that is associated with the use of the excimer laser is irregular astigmatism. This has generally the same as decentralization, characterized by visual disturbances and the onset of visual aberrations.
Irregularastigmatism May in fact be caused by other complications of eye surgery lasers, such as the homogeneity of the excimer laser and wound healing problems. Some flap complications that lead to scarring of the cornea can also cause irregular astigmatism. It can also be caused by excess tissue, which was not sufficiently removed. These tissues, known as center islands disappear spontaneously without intervention.
Treating it requires the use of a capsule of contact lenses. ForPatients who do not want the hassle involved in using contact lenses, an alternative treatment for irregular astigmatism is corneal transplant. However, this method is generally used as a last resort.
In general, the use of excimer laser in laser eye surgery has resulted in benefits to more complications. However, it is important to be aware of possible side effects that lead excimer laser in May, so you can be prepared for all complicationsMay that happen.
