Refractive eye surgery is a surgery that improves the sharpness of a patient’s vision, whether they are nearsighted, farsighted, or astigmatic. Basically, the ophthalmologist or eye surgeon changes the shape of the cornea to make sure that the image that falls through the eye focuses directly on the center of the retina. This technique is what happens during LASIK surgery. Refractive errors of vision happen when the image focuses behind or in front of the retina.
Thanks to the accuracy of the surgery, which uses an ultraviolet excimer laser, surgery to correct refractive errors is very safe, more comfortable than ever, and effective. Here are five advantages of this type of eye surgery:
1. Better Vision
People who have surgery eventually enjoy better vision. It’s estimated that as many as 95 percent of all patients achieve a UCVA, or uncorrected visual acuity of at least 20/40. Most of those patients have 20/20 vision, which is considered normal. There are some people who’s vision is even sharper than this. A person whose vision has been corrected to 20/10, for example, can clearly see something 20 feet away that a person with normal vision has to stand 10 feet away to see. Patients who’ve had their vision corrected to 20/20 or sharper no longer have a need for glasses and even people with 20/40 vision may not need to wear glasses all of the time.
2. No Need to Wear Contact Lenses
Contact lenses are placed directly on the eyes of a person who doesn’t want to wear glasses. Though they give the wearer the benefit of being eyeglass free, they are fiddly to put in, need to be regularly and thoroughly cleaned, and can fall out and get lost. There are some people who don’t tolerate them well, and they need to be replaced fairly often at a cost of as much s $450 dollars a pair. Though corrective eye surgery is more expensive, it only has to be done once.
3. No Need for Eyeglasses in Many Cases
In contrast with people who opt for contact lenses, there are some who wear eyeglasses as a fashion statement as much as they wear them to improve their vision. Still, eyeglasses can be even more expensive than contact lenses, and they can be misplaced or broken. People who have corrective surgery but still want to wear sporty sunglasses or designer eyeglasses no longer need to pay for prescription lenses.
4. Results are Long Lasting
Right after the surgery, the patient’s vision is blurry for a while, so one eye is corrected at a time. It takes about three months for the eyes to settle into their new visual acuity, and both patients and doctors can expect the improvement to be permanent. Ideally, there’s no need for extra surgery unless the
ophthalmologist has under or overcorrected. The only things the should affect the patient’s eyesight from then on are illness that affects the eye or aging.
5. Fast Recovery
Corrective eye surgery is now an outpatient procedure, which means that the patient can go home shortly after the surgery is over. They won’t be able to drive home so should recruit someone to drive them from the clinic or doctor’s office, but after a day or so of rest they are ready to go back to most of their usual tasks.
A good candidate for this type of surgery is no younger than 18 since the eyes of a person younger than this haven’t stabilized. On the other hand, they shouldn’t be too much older than 40, when the eyes may start experiencing presbyopia and have trouble reading the fine print. They may need something other from corrective surgery. People who are in their 70s may be more prone to cataracts which corrective eye surgery can’t fix.
Fast recovery, no need for corrective lenses, whether they’re glasses or contacts, permanent improvement in vision are some of the advantages of getting corrective eye surgery. This surgery is also painless and doesn’t require stitches or dressing. It’s also done on an outpatient basis and saves money in the long run.
