If some form of corrective surgery, it is important that you know what to expect after the operation. As with any procedure, laser eye surgery results in a series of complications. The most common complications in patients undergoing the process has suffered a higher order.
These are risks that may in his vision, not diagnosed in a typical vision of investigation will be. Examples of these so-called higher order halos belongstarbursts, glare, ghosting and even double vision.
Not only are higher-order aberrations irritating, but if severe enough, they can cause considerable impairment in one’s vision. Severe cases of higher-order aberrations have resulted in almost complete loss of contrast enhancement, especially when lighting is inadequate.
In the past, corrective vision surgeries almost always produced this. The problem with older techniques is that the aberrations they tended to produce sometimes cannot be corrected with the use of glasses or contact lenses. With the evolution of newer techniques involving the use of the excimer laser, such as LASIK, the occurrence of this has also decreased significantly. Nowadays, wavefront technology used is able to minimize the occurrence of these.
There is one factor that has been determined to increase the risk of developing pupil size. Researches revealed that the bigger the size of the pupil, the higher the risk that the patient develop these aberrations. That is why a patient who had the procedure has a better view during the day – because the pupil is smaller than during the day into the night. If the pupil is enlarged, the light is able to pass on the edge of the corneal flap, which was created during the process. Thus, the presence of aberrations.
In general, these must be addressed on its own, given enough time, in most cases they have already been resolved 6 months after surgery. If any ofThis mark exist in the past 6 months, the deviations are likely to be permanent and may require additional treatment, so it's important that you consult your specialist of these complications.
Treatment of mild forms of this is about the use of optical lenses, but may have to undergo repeat surgery the most severe forms. Higher order can be measured and treated with wavefront technology. Wavefront-guided customized corrective surgery is the best wayfor their management.
