may be corrected with glasses, contact lenses or refractive surgery
. Depending on your vision problem, you may need to wear your glasses or contact lenses all the time or only when you need distance vision, like driving, seeing a chalkboard or watching a movie. If you're nearsighted, your prescription is a negative number. The higher the numeral, the stronger your lenses will be.Refractive surgery can reduce or even eliminate your need for glasses or contacts.
The most common procedures are performed with an Excimer laser
. In photorefractive keratectomy
, or PRK, the laser removes a layer of corneal tissue, which flattens the cornea and allows light rays to focus closer to or even on the retina
. In laser-assisted in situ keratomileusis
(LASIK) is the most common refractive procedure. Then there's Orthokeratology, a non-surgical procedure where you wear special contact lenses that slowly reshape the cornea over time to correct your myopia. When the lenses are removed, the cornea temporarily retains the new shape, so you can see clearly without the lenses. With orthokeratology or corneal refractive therapy (CRT), an orthokeratology-like procedure you wear cornea-shaping lenses at night, so you have daytime vision without contacts or glasses. Another surgical procedure for correcting mild myopia is the implantation
of plastic corneal rings, which also alter the shape of the cornea. One advantage of the rings is that they may be removed in case of a problem or adjusted should your prescription change. They can also be left in place permanently.
We suggest you LASIK as the choice. To know whether you are a good candidate for LASIK you can follow this link lasik Guidelines. The cost depends on the institute and the technology it uses for the procedure. The number of days of hospitalization is 24 to 48 hrs usually without complications.
