What is LASIK surgery & why is it done

Dr.Prashaant Chaudhry, 4 mins read

You probably know what LASIK eye surgery is; it is after all the most prominently performed laser refractive surgery today, done for correcting problems with an individual’s vision. LASIK or Laser-assisted in situ keratomileusis can provide a permanent solution to wearing glasses or contact lenses.

If you’re considering where you can get affordable LASIK surgery performed by some of the best LASIK eye surgeons in Delhi: you can reach out to us and we’ll assist you all the way. Aakash ranks amongst the best eye care hospitals in Delhi with state-of-the-art technology and comprehensive care programmes, our doctors are some of the best ophthalmologists in Delhi with years of impeccable medical and surgical success.

In case you’re a resident of Dwarka and asking yourself “Is there a safe, reliable, and best LASIK surgery near me?” then Aakash is the place that will conveniently afford you the nearest and safest LASIK surgery available.

In the procedure, a kind of cutting laser is deployed with great care to correctly re-change the shape of the outer clear tissue at the front of the eye (called the cornea) to improve vision for good. Indeed, prescription glasses or contact lenses do correct vision, but LASIK reshapes the cornea itself, permanently.

Why it's done:

LASIK surgery may be an option for the correction of many vision problems like LASIK for myopia and farsightedness. LASIK for astigmatism has also proved a viable option.

All three conditions cause blurry vision, which needs corrective glasses, lenses, and LASIK if the conditions are right.

You can consult some of the best AIIMS-trained LASIK eye specialists in Delhi at Aakash Healthcare and see whether LASIK surgery or similar refractive procedures are options that will work for you. From customized blade-free LASIK to SMILE, all procedures are individualized to perfectly treat your power.

Risk:

LASIK Complications that cause vision loss are extremely rare and we have till now, been very fortunate in this regard at our eye hospital in Delhi. However, there are potential side effects with dry eyes and temporary vision adjustment problems like glare are most common. Don’t worry as these abate in a matter of weeks or months, and next to no people report them as long-term problems.

Dry eyes after LASIK surgery happen as the surgery causes a temporary decrease in tear production in the six months or so after surgery, eyes can feel very dry as they heal. Dry eyes can also reduce the efficiency of your vision and an eye specialist will recommend eyedrops for treating this.

Glare, halos, and double vision can happen, especially during the night; after surgery, this is a matter of days and at most a few weeks. Recovering patients report increased light sensitivity, glare, halos forming around bright lights, and/or double vision. At Aakash Healthcare, we do specialized tests to customize treatment and prevent such complications.

Under corrections will is needed if the laser removes too little tissue from the eye, as it will not give the desired clearer vision results patients hope for. Under corrections are needed more for nearsighted people.

Another LASIK procedure within a year will be needed to remove more tissue.

Other LASIK surgery side effects include Overcorrections as it is equally possible that the laser removed too much tissue from the eye. However, these are harder to fix than under corrections. Astigmatism is seen in exceptional cases and can be caused by uneven tissue removal. It will need additional surgery, glasses, or contact lenses. Problems with the eye flap regrow can become problems along with regression: when vision gradually changes back toward the original prescription but this is very rare and in some equally rare cases Vision loss or changes can take place after.

Certain health worries can aggravate the amount of risk involved in LASIK surgery and/or make the surgery less successful.

The best eye doctors in Delhi will not perform laser refractive surgery for you if you are with certain conditions, which include rheumatoid arthritis, constant dry eyes, hormonal changes if you are pregnant, or breastfeeding if you have a weakened immune system owing to immunosuppressive medications. You can’t get LASIK if you’ve had changes in your vision recently if you have an inflamed cornea, eye injuries, or diseases that affect the eye area, glaucoma, or cataracts

LASIK surgery will not be ideal if you are suffering from an eye disease that has made the cornea thin and bulging, in case you have a fairly good overall vision as it is if you have severe nearsightedness. Very large pupils or thin corneas are not ideal either. Even age-related eye changes are not going to be helped with LASIK.

If you are considering LASIK surgery you may have chanced upon the “ LASIK blade versus bladeless" debate or may be wondering about the cost of bladeless/blade-free LASIK eye surgery, feel free to ask our eye specialists about how the procedures are done.

In traditional LASIK, an instrument known as a microkeratome (the blade) is used and in bladeless a type of high-energy laser (femtosecond laser) is used instead of a blade. This makes more precise and stable flaps as compared with the blade method.

At Aakash healthcare, we perform both microkeratome-assisted and femtosecond LASIK in a customized method known as topography-guided LASIK (also known as Contoura LASIK on some platforms) to enable us to achieve one of the highest success rates in the country.

You may have also encountered the debate of SMILE vs LASIK. While LASIK involves the creation of a flap before the application of laser, SMILE is a flapless technique that removes the power in a single-step method. The advantages of SMILE include less weakening of the cornea, less dryness, and better nighttime vision.
