WHAT IS LASIK

LASIK or Laser-Assisted In Situ Keratomileusis is the latest break-through in vision technology that has transformed the lifestyle of spectacle and contact lens users all over the world. It is one of the most practiced laser eye surgeries for correction of refractive errors such as myopia, hyperopia and astigmatism.
This laser vision correction technique is performed on the cornea (Front clear portion of the eye) so that light entering the eye can be focused on the retina. The procedure involves reshaping of the cornea & changing its focusing power to improve the vision.

Alcon Refractive Suite: FS-200 AND EX-500




FS-200

Faster Flap Creation

  • Featuring the world's fastest flap creation times, the 200 KHz WaveLight® FS200 Femtosecond Laser delivers precise, predictable outcomes
  • Standard flap creation in approximately 6.0 seconds
  • Automated vacuum control of the patient interface for consistent suction
  • Minimized IOP and ocular distortion during suction


Tailored Performance
Offering adjustable hinge position and size, variable side-cut angles, flap sizes, and shapes, the WaveLight® FS200 Femtosecond Laser allows surgeons to expand their treatment options:

  • Adjustable flap centration after suction is applied
  • Intracorneal ring segments
  • Lamellar and penetrating keratoplasty


Precision at Every Turn
The WaveLight® FS200 Femtosecond Laser combines a small focus with low pulse energy and a unique cutting pattern for accurate flap creation:

  • Sharp cutting edges
  • Smooth stromal beds
  • Easy to lift flaps
  • Minimized opaque bubble layer

Ex-500

Customization:
The EX500 was the first excimer laser to offer wavefront technology, which allows our surgeons to customize treatment to the cornea’s unique characteristics and aberrations (imperfections). This helps us treat more complex aberrations and deliver better overall outcomes.

Built for Speed
The EX500 emits 500 laser pulses per second for an extremely quick treatment. The benefit is decreased potential for patient fatigue syndrome, with the procedure being completed in seconds. In addition, the speed of the laser also significantly reduces the risk of complications such as dry eye.

Enhanced Precision:
Alcon’s Perfect Pulse technology ensures each laser beam is calibrated to safely and precisely sculpt the cornea to help you achieve your best visual outcome — and best of all, free of any potential for glare, halos or other visual symptoms!

Eye-tracking System:
The automated eye-tracking system monitors the movement of the eye so the laser beam stays on target during the treatment to deliver the highest levels of safety!

Wide Range of Treatment:
With the EX500, we can treat the highest levels of nearsightedness, farsightedness AND astigmatism. In short, we are able to help patients who were previously told they did not qualify for LASIK.

PREREQUEST FOR LASIK :

1) Age ≥ 18 years.

2) No change or change ❮0.5Diopter in refraction in past 6 months.

3) No eye infections or injuries in past.

4) Normal corneal topography

5) No other eye disorders like dry eye, retinal problems or glaucoma.

6) Discontinue contact lenses for atleast 1-2 weeks prior to testing.

7) No eye infections or injuries in past.

STANDARD LASIK SURGERY:

A standard LASIK involve 3 steps:

STEP 1 :
A flap is created with the help of an automated micro-surgical blade(MICROKERATOME) or with Laser (Femtosecond). Then the flap is lifted and folded back.

STEP 2 :
Excimer Laser which is pre programmed with customized specific measurements for each eye then reshapes the cornea.

STEP 3 :
The corneal flap is then repositioned and the interface is rinsed.

DIFFERENT TYPES OF LASIK

There are 2 different types :

1) Conventional LASIK
2) Blade free LASIK

Conventional LASIK :
In a conventional LASIK a suction ring is placed on the eye to prevent the eye from moving. An automated microsurgical Instrument called the micro-keratome is used to create the corneal flap. Rest surgery is similar as in standard LASIK.

Blade Free LASIK :
'Femtosecond' LASIK is 100% blade free procedure for those of you who feel hesitant about the surgical blade used in blade LASIK. Advantage of this laser is the precision of the flap with characteristics and dimensions that the surgeon customize for each eye. This is a fully auto-mated technique to create the flap.


CUSTOMISED LASIK & TOPOGUIDED LASIK

Customized laser correction is an advance laser treatment for removal of spectacle numbers.
Also known as Contoura vision correction, corrects irregularities in the cornea in addition to correcting glass numbers. This results in better quality of vision and sharp and crisp vision.
It is a US FDA approved procedure. It corrects the power of glasses by treating at the visual axis thereby providing the sharpest possible vision.
Like LASIK it is a painless stitchless procedure without the need of any injection, bandage or hospitalization.
It improves the smoothness of the corneal surface using a special equipment called the topolyser which marks the corneal irregularities thereby enhancing the sharpness of vision and making the cornea an optically perfect surface.

Advantages of Customized Treatment

1) It gives better contrast sensitivity

2) There is Reduced induction of higher order aberrations (HOA)

3) There is greater clarity of vision. Such treatments are specially designed for each individual and tailor made for the particular eye providing fine tuned and prefect outcomes.

CARE TO BE TAKEN AFTER LASIK :

Do's:

You should wear protective eye gear to prevent injury and dust in the eye for 15 days.

Use timely medicines as prescribed.

Eye checkup as advised.

Don't's :

Avoid splashing of water directly in the eye for 5-7 days.

Avoid eye rubbing and eye makeup for 15-20 days.

Contact sports including swimming should be avoided for 4 weeks.

Most people are comfortable to join work 1-2 days after LASIK but individual variations do occur

THINGS YOU SHOULD KNOW ABOUT LASIK

LASIK is an OPD Out Patient Procedure.

No hospitalization is required.

No injection is needed in the eye.

Time is about 5 minutes per eye.

It is safe, accurate, painless and has a quick recovery.
