A good alternative to LASIK eye surgery
When it comes to refractive surgery, the two best options are LASIK (laser-assisted in situ keratomileusis) and PRK (photorefractive keratectomy). LASIK treatment resulted in a faster time, but complications may present as secondary. Moreover, not all individuals are good candidates, and perhaps suffer from severe post-operative when LASIK is performed. PRK is an alternative that is not a longer period, healing, and make the same risksLASIK. Requires more patience and postoperative therapy, but it is a better procedure for patients with thin corneas, eyes dryer and other important factors.
PRK is initially put a ring in the surgical area of the cornea and filled it with alcohol to weaken the bonds of the corneal epithelium executed. Furthermore, this outer layer of the cornea to the page with a brush surgical exposure of the inner layers of the fabric is moved. At this point, the excimer laser ablation is used andTransformation of the inner layers of the cornea. This is the same laser used LASIK. After this step, a contact lens bandage is placed over the surgical field. This objective can re-epithelialization of the cornea. It also protects the cornea and greater patient comfort. The patient should be seen often contact lens until the eye can be monitored for wear and possible cure of wound infection.
The lenses must be removedbetween 4-7 days, once the epithelium is completely healed. In an attempt to prevent infection, individual use of topical antibiotics, as Zymar for at least a week and a topical steroid such as FML for at least six weeks after the operation. The steroid reduces swelling, improves patient comfort and prevent scar formation during the healing period. Depending on various factors, this decline can be changed if the opacity of the cornea is present, there are over / under correction, with an increase in intraocular Pressure or allergy drops. In addition, immediately after the operation, can be of considerable discomfort, pain drops Xibrom used as a reduction of 1-2 days is employed. It should be stopped immediately after the procedure, why not delay the healing process.
How healing is slower and less comfortable initially may, in some patients are reluctant to accept this procedure. Also, sunglasses should be worn for a whole year after '> Surgery because the UV light is often the healing of the cornea cloudy, even after it seems to be complete. This is another difference between PRK and LASIK.
The bottom line is that before you decide to have refractive surgery must be adequately informed to pursue all available options. Then and only then can a truly informed decision. The election should have been by the surgeon, such procedures were for the safest and best for each patient. Itshould not be on individuals on which to rest better. The end result is what matters most is not simply how to get there.
