Here's how to make refractive surgery for myopia a smooth drive
If you are tired of wearing spectacles or contact lenses and wish to get rid of it, then there are various surgical treatment options available. In this blog, we'll give you insight on surgical treatment options if you have myopia (nearsightedness).
What is myopia?
Myopia or nearsightedness is a kind of refractive error in which the person can see objects closer to him/her clearly, but faraway objects look blurry.
Symptoms of myopia
Apart from not being able to see distant objects clearly, you might also notice these symptoms:
- Eye fatigue
- Children with myopia often face trouble reading the blackboard.
Prescription glasses for correcting nearsightedness
The most common way to treat myopia, especially with children, is wearing eyeglasses. The lens of the eyeglass corrects the angle at which the light hits the retina. Before prescribing you with the right kind of lens, your optometrist tests your vision with focus exercises or eye charts. They examine your eye with different angles to check for the type of lens apt for you.
Contact lenses for correcting nearsightedness
Contact lenses correct your vision by changing the direction in which light enters the eye. The natural tear forming in the eyes helps contact lenses to float on the cornea. The different types of lenses include:
Soft contact lenses
Rigid gas permeable lenses
Soft contact lenses are made up of pliable soft plastic that covers a larger portion of the eye. It covers the pupil, iris, and extends into the white. Some soft lenses are meant to be taken out at night, cleaned and stored. While there some soft lenses that should be disposed of after a fixed period, like a day or a few weeks.
Rigid gas permeable lenses are small lenses that usually cover the pupil and extend into the iris. These are made of thin, rigid plastic that floats on your tear. If dust or eyelash gets between these lenses and the eyes, then you need to take them out, clean it, and put it back.
Why go for refractive surgery for myopia?
The refractive surgery aims to correct or adjust your eye's focusing
ability by reshaping the cornea (a clear, round dome at the front of your
For people suffering from myopia (nearsightedness), refractive surgery for myopia reduces the curvature of the cornea that is too steep. The goal is to correct myopia by decreasing the refractive power of the eyes.
Refractive Surgery for Myopia: Treatment options
Benefits of Lasik eye surgery
- Improved vision
- Long-lasting results
- Quick results
- Quick recovery
- No dependency on glasses or contacts
- Improved self-confidence and enhanced lifestyle
Implantable contact lenses:
Reasons to choose SMILE eye surgery for myopia.
- Key-hole surgery
- Beyond Lasik
- Minimally invasive
- Predictable results
- 3rd generation
Lasik stands for laser-assisted in situ keratomileuses. It is the most
common procedure done for correcting myopia and other refractive errors.
Lasik laser eye surgery reshapes the cornea enabling light to focus on
the retina without contact lenses or eyeglasses. This procedure hardly
takes 15 minutes and is pain-free.
Lasik surgery involves creating a thin flap on the cornea with femtosecond laser or microkeratome. This exposes the underlying corneal tissue. Then, Lasik specialists use an excimer laser to reshape the cornea in a unique pattern for each patient.
PRK stands for photorefractive keratectomy. It is a better surgical procedure than Lasik for someone whose cornea might be too thin. In this surgery, a manual instrument is used to scrape epithelium (outer layer of the cornea). Then, an excimer laser is used to reshape the cornea. The corneal abrasion takes at least four days to heal, resulting in blurred vision and moderate pain.
Corrective lenses can also be implanted/inserted in the eyes to improve the vision. Implantable contact lenses are a good option with the highest level of nearsightedness. In this procedure, the lens is implanted just behind the iris or between the cornea and the iris. This is considered an alternative to Lasik for older people who may need cataract surgery in the future.
The SMILE laser eye surgery is a short form for Small Incision Lenticular Extraction. It is a highly advanced technology of blade-free laser vision correction, with even more precision than Femto-Lasik procedures that are widely done. SMILE does not have any need for the corneal flap. It is a fully automated procedure that is completed in a short time to give long-lasting and stable results. Aside from myopia, it can also be used to treat astigmatism with cylindrical power up to 5 Diopters.
