While LASIK surgery is suitable for most people, it may not be appropriate for others. A person is most likely ideal for laser eye surgery if they have had a stable prescription for 12 months, have an otherwise healthy eye, and are in good general condition.

 

How Does LASIK Work?

There are two phases in LASIK. First, the surface of the cornea is cut to create a flap that allows access to the central portion of the cornea. The cornea is then shaped using an excimer laser to obtain the perfect vision. Previously, only microkeratomes with a high-speed oscillating blade could be used to create the flap. There is now ‘bladeless LASIK,’ which uses the femtosecond laser to create the flap.

The procedure takes around 15 minutes and does not require general anaesthesia. Patients generally notice an improvement in their vision right after the LASIK and have a near-normal vision by the next day. In just one or two days, normal activities can be resumed.

 

Other Factors That Determine The Suitability

You may find out if you are a candidate for Lasik eye surgery by consulting an eye doctor. In addition, before seeing a doctor, consider the following things. The following factors may also indicate that LASIK isn’t right for you:

 

  • Over 40 years old.

Presbyopia, or the loss of close vision, is a part of growing older. It causes a person’s ability to read close-up items, such as menus or a cell phone, to deteriorate with time.

 

  • Under the age of 20 years old.

Before getting Lasik eye surgery, it’s a good idea to be sure your prescription is stable as Lasik is a permanent procedure. It’s typical for your eye power to change if you’re under the age of 20.  As a result, it is best to postpone it until beyond the age of 20.

 

  • Refractive errors are high.

LASIK can only correct your vision if your spectacle power ranges between -7 D and +4 D. As a result, if a patient suffers from extreme myopia or hyperopia, it is not advisable to get LASIK.

 

  • Certain Eye disorders.

If you have a history of any of the following, talk to your doctor:

    •  Herpes simplex.
    • Glaucoma.
    • When the pressure in your eyes is above normal, but there are no visible changes in vision or damage to the eye structure, you have hypertension.
    • Inflammation of the eyes.
    • Injuries to the eyes.

 

  • Other Medical Conditions.

    Because of the risk of complications with healing, those with some medical issues or who take certain drugs should avoid it.

The following are such examples:

  • Taking medicine to treat an illness that makes it difficult to heal wounds.
  • HIV infection is one example of such illness.
  • Taking retinoic acid or steroids for diabetes.

 

  • Limitations During Pregnancy or Breastfeeding.

Women who are pregnant or nursing are advised to postpone LASIK. The female body’s hormone levels are high during this time, resulting in tissue relaxation and an increase in spectacle power. Even while this rise in spectacle power occurs in just 10% of instances, it is a significant enough percentage to warn against LASIK during this time. The change in spectacle power is generally between 0.5 D and 1.0 D in those females when the number increases during pregnancy.

 

  • You are suffering from Dry Eye Syndrome.

The dry eye condition is typically a no for Lasik surgery. A person with dry eyes is more likely to have considerable post Lasik pain as well as an aggravation of dry eye symptoms. Dry eyes might also slow down the healing process.

 

  • It will put your job in jeopardy.

 LASIK might be prohibited in some occupations. As a result, before going for LASIK, be sure to verify with your company where you work.

 

  • You are a regular participant in contact sports.

You engage in activities such as boxing, wrestling, martial arts, or other sports where punches to the face and eyes are common. Then LASIK surgery is not advisable.

 

  • Your corneas aren’t very thick.

The cornea is the transparent, thin layer of the eye that covers the iris, which is the colourful portion of the eye. LASIK reshapes the cornea to modify the eye’s focusing ability (for example, by removing tissue). But if LASIK is performed on a cornea that is excessively thin, it might result in blindness.

 

After LASIK, What to Expect?

While most patients will see a fast improvement in their eyesight after the surgery, the cornea may take two to three months to heal.

During such period, you should avoid doing the following:

  1. Swimming pools and hot tubs.
  2. Sports involving physical contact.
  3. Driving at night if you experience difficulty seeing at night.
  4. Using creams, make-up, or scents (ask your doctor when it is safe to start using these again).

 

Who is Suitable for LASIK?

The ideal individual will have stable vision, a sufficiently thick cornea, good overall health, and a positive mindset. The best age for the procedure is between 20 and 40 years old.

 

Femto LASIK

Blade-free LASIK, all-laser LASIK, and bladeless LASIK are all terms that describe Femto LASIK. For Femto LASIK, the surgeon utilises two types of lasers. The first is a highly advanced femtosecond laser, which is used to generate a thin cornea flap, followed by an excimer laser to restructure the underlying corneal tissue or stroma. The flap is then replaced, with no blades required, to assure crystal clear vision. 

 

Conclusion

For most persons with otherwise healthy eyes, vision correction is possible. However, it may not necessarily be laser eye surgery. Please do your research before selecting a hospital/Centre for LASIK surgery in New Delhi.

  1. Learn about the devices used during your operation and whether another procedure, such as LASEK, would be a better fit for you.
  2. Make sure that the doctor you select has a lot of experience.
  3. Make a clear estimation of LASIK surgery cost to see if it’s within budget.
