If you get LASIK eye surgery, you won’t need a corrective lens anymore. However, it could be a better fit for some. Read on to find out if you’re a good candidate and what factors to consider if it is right for you or not.
Tired of your glasses or contacts? LASIK might be the solution for you. As a vision correction procedure, LASIK helps people see clearly again. All things considered, most people’s 20/20 vision after LASIK is quite enough. Most people will need glasses for nighttime driving or reading as they get older. The results from LASIK surgery are positive. Only rarely do patients experience permanent vision loss as a result of problems, and the vast majority are pleased with their experience. The most prevalent negative effects are dry eyes and brightness.
However, most people have a full recovery from their symptoms within a few weeks or months, so they are rarely viewed as chronic problems. Findings are affected by refractive error and other reasons. Mild cases of nearsightedness respond favorably to refractive surgery. Unpredictability is increased by astigmatism and excessive nearsightedness or farsightedness. If you’re trying to figure out if this treatment is right for you, you’ll want to read on.
What is LASIK?
There is great variety in laser refractive surgery. The vast majority of patients choose LASIK. The term “LASIK” is used interchangeably with “laser eye surgery.”
The retina is typically the target of an image’s concentration. With nearsightedness, farsightedness, and astigmatism, the eyes focus in front of or behind the retina, resulting in distorted vision. Myopia is characterized by blurred vision at long range but sharp vision up close. If your eyeball is slightly longer than average or if your cornea curves too sharply, light rays will focus in front of the retina, blocking your farsightedness. There is a marked improvement in visibility between near and far objects. Near things are blurry for someone with farsightedness (hyperopia), but those in the distance are crystal clear. If your eyeball is too short or your cornea is too flat, the light will focus on the back of your eye instead of the retina. This causes distortion at both near and vast distances. Vision impairment due to astigmatism. When the cornea has an irregular curvature or flattens, near, and distance vision are affected. Correcting vision impairment with lenses that refract light is called an optical correction. Refractive errors and visual blurriness can be corrected by reshaping the cornea, the dome-shaped transparent tissue at the front of the eye.
Your eyes will be examined and measured by your lasik eye surgeon before LASIK. Before surgery, a little sedative may be administered. Once you are relaxed on the operating table, numbing drops are administered to your eyes. After that, a laser will be used to precisely alter your cornea’s shape. In order to change the cornea’s shape (flatten or steepen it), your eye doctor will use a laser to remove tiny amounts of tissue in discrete pulses.
Before reshaping the cornea, the surgeon will typically extract a flap of tissue from the surface. Raising a small flap or none at all are two alternatives. In spite of their similarities, there are drawbacks to every approach.
How’s the state of your vision?
- Laser eye surgery can restore regular vision when a refractive defect is mild to severe. Your eye surgeon will inquire extensively into your history of vision problems and thoroughly examine your eyes to ensure a smooth procedure. Some examples are:
- Keratoconus is a disease that thins the cornea and impairs vision. Avoid having elective eye surgery if keratoconus runs in your family, even if you don’t have the condition yourself. Illnesses affecting the eyes, such as herpes simplex, cause irritation. Injury or trouble with the eyelids.
- Dryness: It’s possible that the LASIK procedure will make your dry eyes much worse.intensely large eyes. Large pupils may not be a good candidate for LASIK surgery in low light. After surgery, halos, starbursts, and eerie ghost visions are all possible side effects.
- Glaucoma: Glaucoma might become even more severe if the eye pressure is raised during surgery.
- Cataracts: it is Roughly equivalent to extreme myopia, a high refractive error. The risks of LASIK surgery may not be worth the potential rewards.
If You have excellent eyesight and only need contacts or glasses infrequently, the surgical correction might not be worth the risk.
- Vision loss occurs as you age due to the natural deterioration of the eye (presbyopia). You partake in high-intensity sports if you’re a martial artist or boxer who takes a lot of punches to the face and eyes.
LASIK surgery might not be for you:
Our eye doctor will also conduct a thorough health examination. It is possible for LASIK surgical risks to increase or the outcome to be less predictable due to unrelated medical concerns. Examples:
Conditions including rheumatoid arthritis, lupus, and HIV can make it difficult to recover from injuries or prevent you from fighting infections. When drugs are used to suppress the immune system. Diabetic retinopathy is a complication of poorly managed diabetes.
- Is your eyesight steady?
Myopia can affect vision throughout adolescence and beyond, requiring regular adjustments to the prescription for corrective glasses or contact lenses. Therefore, those over the age of 18 are the ideal candidates for LASIK.
Vision alterations could occur during pregnancy, breastfeeding, or the use of steroids. Your eyesight must stabilize before LASIK can be performed.
- If you can afford the LASIK surgery?
Laser eye surgery is considered elective and not covered by most insurance policies. Find out what your procedure will set you back.
- Negative effects:
It includes dry eyes and temporary visual anomalies; however, permanent eyesight loss is extremely uncommon. However, most people have a full recovery from their symptoms within a few weeks or months, so they are rarely viewed as chronic problems.
Dryness: Tear output may temporarily decrease after LASIK. After surgery, you may experience dry eyes for up to six months. Your eyes’ dryness may get worse once they’ve healed. Your optometrist may advise you to use eye drops. Tear duct plugs can be helpful if you suffer from severe dry eyes since they prevent tears from evaporating.
Vision distortion, halos, and glares are all possible effects. Possible postoperative night-vision impairment after surgery There is a possibility of double vision, glare, and light halos. It may subside after a few days or weeks or become chronic.
Under Corrections: The laser has to cut away enough tissue to make a difference in your eyesight. Undercorrection is more common among nearsighted people. You may require further tissue removal during refractive surgery within a year to achieve optimal results.
Over Corrections: In extreme cases, the laser could eliminate too much healthy eye tissue. Corrections are more difficult to undo than their incorrect counterparts.
Astigmatism: Astigmatism is brought on by a loss of tissue that isn’t uniform. Maybe you’ll need contacts, glasses, or surgery.
Ectasia: It is caused by myopia progression and corneal steepening. Corneal ectasia is a serious eye disorder.
Problems with the flap: Folding back or removing the flap from the front of the eye during surgery might lead to infection and severe tearing. During the healing process, the epithelium (the outermost layer of corneal tissue) may develop abnormally under the flap. Irreversible loss of sight. Impairment of vision due to surgical complications is extremely uncommon. There’s a chance that some people have blurry vision.
