A Brief Introduction To Lasik Eye Surgery

Any surgery that aims at correcting the refractive errors in the eye is known as a ‘Refractive Surgery’. The secondary goal of refractive surgery is to eliminate or reduce one’s dependence on corrective glasses or contact lens. The first successful refractive surgery was performed in 1963 by an ophthalmologist Jose Barraquer. The new technique he used for making refractive corrections is called ‘keratomileusis’ which is Greek for ‘corneal reshaping’.

What is Lasik eye surgery?

After decades of research and advancements, ophthalmologists developed several refractive correction techniques which later involved the use of high-intensity light beams. And today, the latest and safest form of refractive surgery developed and performed is the LASIK (laser-assisted in situ keratomileuses) surgery.

The Latin phrase ‘In-situ’ means ‘in place’ or ‘on-site’. Hence, ‘Lasik’ basically stands for ‘laser-assisted corneal reshaping in its original position’.

The idea behind this procedure is to reposition the cornea such that the light entering it precisely falls on the retina. This way, Lasik is typically used to cure or significantly reduce the effects of three types of refractive errors, i.e., myopia, hyperopia and astigmatism.

Additionally, Lasik surgery is also recommended for people who have:

• Congenital eye deformities
• Extreme nearsightedness
• Larger pupils or thinned corneas
• Autoimmune disorders like rheumatoid arthritis
• Eye disorders such as inflamed cornea or uveitis

How is Lasik surgery performed?

This surgery uses a cool ultraviolet laser beam known as the excimer laser and a microscopic tool known as the microkeratome for reshaping the cornea.

The laser system is completely automated and computerized accordingly to the condition of your eye.

The surgeon first makes water-soluble markings over the eye surface as reference lines. Then, he uses the microkeratome tool to incise the thin outermost layer of the eye such that it folds back as a flap without detaching entirely from the eye, hence, forming a hinge.

The corneal tissues that lie under the hinged flap, known as the ‘Stroma’, are subjected to the cold excimer laser for less than a minute. This laser freezes and removes microscopic amounts of the corneal tissues to reshape and realign it.

Finally, once the desired corneal shape has been achieved, the hinged corneal flap is repositioned referring the markings accurately and allowed to heal naturally.

What are the benefits of having Lasik eye surgery?

• The surgery is non-invasive, which makes it faster to perform and to heal.
• The success rate of Lasik surgery is as high as 96%, making it the safest eye surgery today.
• This surgery involves minimal risk of complications associated with the laser used, typically less than 1%.
• The results of this surgery reflect instantly. Some people can experience sharper vision the very next day as well.
• These results stay for as long as one’s lifetime and can also be easily altered if the desired shape isn’t achieved in the first try.
• A significant amount of patients have also reported a drastic improvement in their night vision and peripheral vision with Lasik treatment.
• Since it discards the use of spectacles and lenses, it also prevents the eye from the headaches and bacterial infections caused by them.

Lasik surgery has been extensively researched and clinically approved for the past 20 years and counting. However, the fact of the matter is that the results of this surgery primarily depend on the skills and experience the surgeon carries. Hence, if you’re willing to have a Lasik surgery in Pimpri Chinchwad area, look for a clinic which comprises of highly experienced Lasik surgeons with the latest Lasik technology at hand. Lifepoint hospital is one such eye treatment centre which is widely commended for providing the best Lasik surgery in Wakad. You can learn more about their eye speciality treatments on the Lifepoint website.
