Refractive eye surgery, also known as vision correction surgery is surgical procedures aimed to fix or improve the refractive state of the eye. It is a simple and safe alternative to glasses or contact lenses since it can treat a range of very common vision problems, including nearsightedness, farsightedness, and astigmatism. There are various methods to do the surgery, but the most common method is using excimer lasers to reshape the curvature of the cornea. It is important to note that refractive eye surgery is not for everyone. Generally, the most suitable candidates are people who are at least 18 years of age, have a moderate degree of refractive error, and not pregnant or nursing.
The most common types of refractive eye surgery are laser in-situ keratomileusis (LASIK), refractive lens exchange (RLE), presbyopic lens exchange (PRELEX), phakic intraocular lens (PIOL), photorefractive keratectomy (PRK), and limbal relaxing incisions (LRI). You will need to consult and discuss with your doctor which type is the best for you. Your doctor will ask you detailed questions regarding your medical history and overall health. During the surgery, you are given either local anesthesia in the form of eye drops or general anesthesia. You can also request a mild sedative to help you relax if your doctor uses local anesthesia.
You may go back to your hotel on the same day once the effects of the anesthesia wear off. Some of the types of procedures, such as LASIK only require you to stay in the Curitiba for 3 days, but other types may require longer time. A full recovery period may take up to 6 months, but you should be able to return to work within a few days. Your doctor will give you a set of aftercare instructions, which you need to follow. The success rate is exceptionally high, for LASIK, 95% of nearsighted patients achieved improved vision.
