Abstract: preoperative examination includes naked visual acuity, best corrected visual acuity, optometry, corneal topography, ocular axis, corneal thickness, ocular surface and fundus. The results of preoperative examination will directly determine whether myopia surgery can be performed.
with the development of medical technology, myopia surgery is also improving. Now more and more myopia friends choose to get rid of myopia through surgery and obtain clear and stable vision.
but there are still many people with myopia who don’t know what to pay attention to before and after myopia surgery. Let’s talk about popular science now.
first talk about preoperative examination. The preoperative examinations of
included naked visual acuity, best corrected visual acuity, optometry, corneal topography, ocular axis, corneal thickness, ocular surface and fundus. The results of preoperative examination will directly determine whether myopia surgery can be performed.
before preoperative examination, It should be done:
stop wearing soft contact lenses (contact lenses) for 1 ~ 2 weeks, hard contact lenses for 3 ~ 4 weeks and OK lenses for 3 months;
exclude acute eye lesions, such as acute conjunctivitis, keratitis, iridocyclitis, undiagnosed high intraocular pressure, uncontrolled glaucoma and fundus lesions;
In order to accurately determine the refractive state, rapid cycloplegic optometry is necessary, and fundus examination with dilated pupils is also very necessary.
during the examination, what patients need to do is to cooperate well with doctors. For example, keep your eyes open and still during the inspection. Full cooperation can ensure the rapid completion of the inspection and the accuracy of the results.
because eye drops of surface anesthetics are used during the operation, there is generally no discomfort during and after the operation. When the anesthetic effect subsides, Discomfort can occur for a short time (usually relieved after 2 ~ 3 hours), including eye soreness, dryness, pain, tears, photophobia, etc.
The visual acuity recovery after surgery varies according to different surgical methods and individual recovery ability. Most people can recover to normal visual acuity on the first day after surgery, and some people recover slightly slower, which is a normal phenomenon. The stable period of postoperative visual acuity is generally 1 ~ 3 months.
1. Don’t rub your eyes hard.
your eyes will be a little more sensitive than usual just after corrective surgery. Any disturbance may make you want to rub your eyes. Xiao Bian’s suggestion is: in any case, don’t rub your eyes hard, let alone after the operation? You can try to blink more ~ ~ ~
2. Remember to drop eye drops
generally, eye drops and artificial tears are needed after myopia surgery to keep your eyes moist. At the same time, regular reexamination is also required, one day, one week, one month, three months and half a year after operation. Regular reexamination can timely understand the situation of postoperative recovery, and doctors can also deal with possible problems in time.
3. Don’t exercise violently.
it’s best not to participate in all kinds of fierce confrontational sports to avoid hitting your eyes. At the same time, we should also develop good eye habits, use mobile phones, computers, etc., and rest for ten minutes every 40 minutes or so to let our eyes look into the distance and relax.
