Your eye vision is sophisticated, sensitive, and important not for you but also your respective doctor. For almost 30-35 years (with the beginning of its invention in India), laser eye surgery has been one of the most common surgeries for people with any kind of eye problem. The procedure has been well-established and the different types like SMILE, LASIK, and ASLA have been extensively developed for the sake of the health of the human eye.
Because of the safety, complications, and possible risks involved, many people ask Is laser vision correction surgery safe? Eye correction surgery with laser light is also known as laser vision correction surgery. This surgery is done by eye surgeons to correct or improve the vision permanently.
What is Laser vision correction?
Laser vision correction (LVC) surgery helps correct refractive errors. Refractive error problems are caused by an imperfectly shaped cornea. LVC surgery is an alternative to spectacles and contact lenses that can help a patient to see clearly and far better.
- Laser vision correction surgery is performed by using laser beam rays to reshape the cornea to adjust its focusing power.
- These operations procedures are both safe and have a high success rate.
Although eye vision correction surgery sounds simple to perform, a lot of planned thought and customizations are needed to obtain satisfactory and positive results. Consult an Eye specialist in Chennai for vision correction surgery.
What is the refractive error of the eye?
Refractive errors occur in the eyes and cause visual impairment. In these circumstances, a patient is unable to focus on the images or objects, resulting in a blurred image. Generally, you have a refractive error when your eye does not refract (bend) light properly on your retina.
These are the 4 basic types of refractive errors:
- Nearsightedness (myopia) – It is a common vision condition in which nearby objects appear sharp and distant objects appear blurred. Nearsightedness starts affecting your eyes at the age of 6 when the child starts watching TV or using various LED electric products. When you watch TV or use any other high frequency LED electronic product, your eyes become longer than normal from front to back, the primary reason for nearsightedness. In this case, the Images focus in front of the retina (or do not reach the retina).
- Farsightedness (hyperopia) – It is a common vision condition in which distant objects can be seen clearly, but nearby objects appear blurred. When you are affected by farsightedness, you may feel your eye shorter than normal & the cornea as too flat.
- Astigmatism – It is a general treatable vision condition in which objects at any distance (Distant or Nearby) appear blurred. The cornea, lens, or both gets into the type of shape that doesn’t allow the reflection or refraction of images directly or sharply on the retina.
- Presbyopia or aging eye – It is a refractive error that can be treated by wearing corrective eyeglasses. Presbyopia often occurs between ages 40 and 50. It is an age-related vision condition when the eye loses its natural power, and ability to see objects (Distant or Nearby) or change focus flexibility because of the natural aging process. Refractive surgery can’t correct this problem. It can make distance vision clearer. But it can make near vision worse.
Is laser vision correction surgery safe?
Yes, Laser vision correction (LVC) is considered the safest and most effective eye correction surgery to obtain a “specs-free” life for patients with
- Nearsightedness (Myopia)
- Farsightedness (Hyperopia)
- Astigmatism (blurring of vision due to the improper shape of the eye).
Before eye correction surgery, a complete preoperative assessment can decide whether the surgery is right for you and, if so, which laser vision correction technique is best.
What are the techniques for Laser vision correction?
There are 3 best techniques and approach options used by an eye specialist for laser vision correction, including –
- Photorefractive keratectomy (PRK)
- Laser-assisted stromal in situ keratomileuses (LASIK)
- Small incision Lenticule Extraction (SMILE)
Photorefractive keratectomy (PRK) is the first generation or one of the first invented techniques under the category of laser vision correction This kind of refractive surgery uses laser beam rays to treat vision problems caused by refractive errors in your eyes. This procedure improves eye vision by using a laser ray and changing the shape of your cornea.
- Surgery Result: The effects of PRK surgery are permanent.
- Success rate: The success rate of PRK surgery is 80 – 90 percent.
- Risk and complication: PRK laser eye surgery also has risks and complications. The possible risk and complications of PRK laser eye surgery include –
- Discomfort
- Pain
- Itching
- Infection
- Cloudy vision
- Dry eyes
- Under corrections
Night blindness
LASIK (Laser-assisted stromal in situ keratomileuses) is the second generation of laser vision correction. This kind of refractive surgery uses a programmed laser beam to reshape your cornea by removing a tiny amount of corneal tissue so that it refracts light better for vision correction. LASIK is proven to be a safe procedure and works 100% on your eyes, giving back more than half of your eye vision..
- Surgery Result: The effects of LASIK surgery are permanent.
- Success Rate: The success rate of LASIK surgery is 85 – 95 percent.
- Risk and complication: LASIK laser eye surgery also has risks and complications. The possible risk and complications of LASIK laser eye surgery include –
- Vision loss or changes
- Dry eyes
- Infection
- Flap problems, including infection and excess tears
- Difficulty seeing at night
- Under corrections
- Over corrections
- Double vision
SMILE (Small Incision Lenticule Extraction) is the third generation of laser vision correction and is a more minimally invasive procedure than PRK and LASIK. This kind of refractive surgery uses a femtosecond laser to create a corneal lenticule which is extracted whole through a small incision without the use of an excimer laser.
- Surgery Result: The effect of SMILE surgery is permanent.
- Success Rate: The success rate of SMILE surgery is 85 – 95 percent.
- Risk and complication: SMILE laser eye surgery also has risks and complications. The possible risk and complications of SMILE laser eye surgery include –
- Night vision issues
- Infection
- Dry eyes
- Inflammation
- Clouded vision
- Doble vision
- Corneal bulging
- Blindness
- Miscorrection can lead to a separate or repeated procedure for the eye problems
Is laser vision correction surgery safe? What are the possible benefits of laser vision correction surgery?
The main benefits of laser vision correction surgery include –
- Immediate improvement in eye vision – Laser vision correction surgery helps you see clearly after a few-week recovery procedures.
- Cost-saving – With laser vision correction surgery, you can save the money that you spend on contact lenses, glasses, and accessories.
- Permanent results – Laser vision correction surgery results are typically permanent.
- Boosted self-confidence – You might feel stuck if you wear glasses all the time. Sometimes, you may feel self-conscious about them and they might not suit your personality or outfits, causing you interruption throughout your routine activities.. You might also have very thick lenses that annoy you and don’t work well with your look, but corrective eye surgery can improve your vision so that you can go without glasses and feel more confident about your appearance.
Conclusion:
Laser vision correction surgery may not suit everyone but make sure that you have stable healthy eyes and you have a cornea that is the correct shape and holds power. Consult a free consultation to withstand the effects of surgery because you need to qualify the aspects to be the right candidate for the surgery. For this, your doctor may examine you comprehensively and may suggest to you the condition of your eyes.
