WHAT IS REFRACTIVE SURGERY / LASER VISION CORRECTION
If the eyeball is longer or shorter than normal or the shape of the cornea is deviant from normal, a person needs to wear glasses or contact lenses to help focus the light on the eye camera film (retina).
We can’t change the length of the eyeball, but we can surely remove glasses by working on the cornea or on the lens The process by which the shape of the cornea is remodelled so that you don’t need glasses anymore is called REFRACTIVE SURGERY or LASER VISION CORRECTION
Dr. Amruta is highly experienced in helping patients to eliminate or reduce their need for the contacts and eyeglasses they use for near-sightedness, farsightedness or astigmatism.
Laser vision correction procedures are highly effective and most patients no longer need contacts or eye glasses for distance vision.
REFRACTIVE LASER SUITE:
We strongly believe that eye care, to be truly effective, is all about harnessing state-of-the-art technology to be operated by the deft hands of experts.
It is the pride of our clinic, as it offers patients the individualized treatments they deserve.
The refractive suite is equipped with the top excimer laser with the fastest laser source at 500Hz (EX500) to create the flap.
The innovations and technical specifications of the Excimer laser offer:
Full control in the hands of the surgeon
It is the fastest platform in the world for creating a flap, offering precise and predictable results:
Reduction of intra-ocular pressure.
Quick restoration of vision.
Automatic suction control of the cross-linking cone for greater stability.
Flap creation in just 6’’.
Customized centration of the flap after the cross-linking.
Visible procedure during the creation of the flap
Connection through a server with all diagnostic equipment as well as with WaveLight’s EX500 to avoid errors during data transfer
ADVANATAGES of LASER VISION CORRECTION
entire procedure takes 10 or 15 minutes
INJECTION, only a numbing anaesthetic eye drop.
recovery is rapid and patients report very little post-operative
discomfort or pain which usually dissipates in a few hours.
- The return of vision is rapid, and 80 to 90% of the visual recovery may be present by the next day.
WHAT ARE THE DIFFERENT SURGERY OPTIONS AVAILABLE
LASIK utilizes the excimer cool-beam laser to vaporize a small amount of corneal tissue beneath the surface of the cornea to reshape the cornea. LASIK is an acronym for Laser-Assisted in-Situ Keratomileusis.
To perform LASIK, the surgeon uses an instrument called a microkeratome to create and fold back a thin layer of cornea. The creation of this flap takes about 30 seconds and the only sensation the patient feels is pressure and an occasional pinching of the eyelid.
2) PRK (Photo Refractive Keratectomy) is a form of laser eye surgery used to precisely alter the shape of the cornea by removing a small amount of cells from the outer layer using an excimer laser. PRK surgery is extremely effective and can greatly improve your vision without cutting a corneal flap as is done with the LASIK procedure.
We believe it is one of the safest and best method of laser vision correction available today. PRK has the following advantages over LASIK:
- Equal visual outcomes than LASIK
- Absence of corneal cutting, flap creation and weakening the cornea
- The low incidence of complications related to creating a LASIK flap is avoided because
there is no flap
- Extremely low chance of serious complications; PRK has lower chance of serious
complications than long term contact lens wear
- Lack of dry eye symptoms induced by procedure
- Slightly longer visual recovery time ( about 10-15 days)
3) FEMTOSECOND LASIK /BLADEFREE LASIK
A newer flap making method utilizes the femtosecond laser (Intralase) to create a flap. The laser can create a flap in less than a minute at a precise depth. However, it is still a procedure that as it involves creating a flap, it has a similar profile of risks and benefits as LASIK.
Advanced computer technology, including wavefront technology is used to adjust the laser for your particular prescription. You will be asked to look at a green blinking target light for a short time the WaveLight®EX500 Excimer Laser is equipped with a special tracking device that helps to centre the laser on the proper position over your eye and follows your eye even if it moves.
The laser light pulses will then painlessly remove the tissue. The thin flap of corneal tissue is folded back into its original position where it bonds after several minutes of drying.
WHAT ARE THE VARIOUS LASER VISION CORRECTION PROFILES
1. ASPHERIC LASIK
2. CONTOURA VISION CORRECTION ( TOPOGRAPHY GUIDED LASIK )
3. CUSTOM LASIK ( WAVEFRONT GUIDED LASIK )
4. WAVEFRONT OPTIMISED (WFO)
5. PRERSBYOND LASER BLENDED VISION
Presbyond laser blended vision is a treatment for people who have an age-related vision disorder, known as presbyopia. As we age, the natural lens of our eyes starts losing its flexibility. It results in the loss of our ability to near-focus.
Presbyond laser treatment is suitable for people suffering from presbyopia. It is primarily used to compensate for reading glasses, though it can also be combined with correction for refractive errors like short-sightedness, farsightedness and astigmatism. Many patients above the age of forty consider going for Presbyond laser blended vision while going for any laser vision correction.
Benefits of Presbyond laser treatment
Works like Lasik:
Presbyond laser treatment is an advanced form of Lasik vision correction. It uses a well-established procedure with proven long term results.
Presbyond laser treatment is always tailor-made based on an individual’s requirements
Minimally invasive and offers quick recovery:
People who have undergone presbyond laser treatment can experience clear vision within 48 hours after the procedure.
You DO NOT need an eye operation. t's a "Stichless" procedure.
NO INJECTION, only a numbing anaesthetic eye drop.
Visual recovery is rapid and patients report very little post-operative discomfort or pain which usually dissipates in a few hours.
