No matter how ready you are for life without lenses, the decision to have LASIK is a big one. You want to know for certain that you are getting the safest, most trusted treatment available. That is why our centre offers the most advanced approach to LASIK including VISUMAX-LASIK .

Refractive correction using LASER has seen tremendous advancement since its first use in 1989. Different types of laser refractive surgeries are:

Lasik: Laser Vision Correction
LASIK or Lasik (laser-assisted in situ keratomileusis) is a type of refractive surgery for correcting myopia, hyperopia, and which the reshaping of the cornea is done by using excimer laser beam to alter its curvature. It corrects vision by altering the refractive power of the eye by producing a calculated change in the curvature of the cornea. The procedure is relatively simple and comfortable. Eyes of the patient are made numb by instilling anesthetic eye drops. Using an instrument called microkeratome a thin flap of corneal tissue is raised. The excimer Laser then ablates the cornea by removing a predetermined precise amount of tissue from inner cornea. The corneal flap is then repositioned back where it bonds without the need of stitches.

There have always been concerns about LASIK because of its tendency to induce higher-order aberrations. Higher-order aberrations are visual problems that cannot be diagnosed using a traditional eye exam, which tests only for acuteness of vision. Severe aberrations can cause significant vision impairment. These aberrations include starbursts, ghosting, halos, double vision, and a number of other post-operative complications.
The advancement of the LASIK technology has helped reduce the risk of clinically significant visual impairment after surgery. Wavefront-guided LASIK is a variation of LASIK surgery in which, rather than applying a simple correction of focusing power to the cornea (as in traditional LASIK), a spatially varying correction, guiding the computer-controlled excimer laser with measurements from a wavefront sensor is done. The goal is to achieve a more optically perfect eye, though the final result still depends on the physician's success at predicting changes that occur during healing.

Blade free Lasik
One of the advancement in Lasik is the state of the art femtosecond laser. The use of blade to cut the corneal flap is replaced by all Laser option, where the flap is created using the femto laser. This is the same revolutionary technology that is used by NASA and the US AIR FORCE to rectify Refractive errors of its astronauts and fighter pilots.

Intralase is a particular type of femtosecond laser which was first to be used for Blade Free Surgery. The more advanced femtosecond laser, from Carl Zeiss Meditec, called the VisuMax is now available in market. The VisuMax is a fifth generation femtosecond laser, which has several advantages over the Intralase for Blade Free LASIK. We feel proud to be equipped with this latest technology for delivering the best services to our patients and feel immense pride in saying that we brought this facility even before it was available to patients in big metros like Delhi, Mumbai, and Chennai.

The VisuMax uses a much lower pulse energy (100 nJ compared with 800 nJ) than the Intralase, and a much higher frequency (500 KHz as opposed to 60 KHz). This results in much less inflammation of the eye post LASIK, and a faster and easier procedure. The VisuMax also used a curved contact glass on the cornea, as opposed to the Intralase, which uses a high scleral suction. The patient experiences a blackout during the Intralase procedure, which does not happen with the VisuMax. Many patients get a red spots in the white of the eye after Intralase-this never happens with the VisuMax. Finally, and most importantly, the amount of gas bubbles produced with the Intralase is much higher than with the VisuMax. This leads to an inaccuracy of the flap thickness, and does not allow a very thin flap to be produced with the Intralase. This has significant effects on the safety of the procedure.

The procedure is carried out as follows:

Step 1. Blueprint made of your eye
In order to deliver the exact correction you need, Iris Registration and WaveScan 3D Mapping creates a blueprint (or fingerprint) of your eye. This allows our surgeons to custom-fit the LASIK procedure. This step involves mapping the individual curvature of your cornea, to the microscopic nuances of your anatomy, allowing us to deliver the exact correction required.

Step 2. Corneal Flap & Vision Correction
a. An ultra-fast laser creates a thin corneal flap, which is then folded back. The process is...
  • Ultra–fast pulses of laser light position microscopic bubbles at a precise depth determined by your doctor.
  • The laser light passes harmlessly through your cornea, and then creates rows of bubbles just beneath your corneal surface as it moves back and forth across your eye in a uniform plane.
  • Next, the laser stacks bubbles around your corneal diameter to create the edges of your flap. These bubbles are stacked at an angle that is determined by your doctor and is individualized to the way your eye is shaped.
  • The process takes only about 15sec from start to finish— it’s quiet and comfortable.
  • Your doctor then gently lifts the flap to allow for the second step of your LASIK treatment. When treatment is complete, the flap easily “locks” back into position and rapidly begins to heal.

b. A second laser corrects your vision, based on your eyes exact measurements and specifications.

You can expect this procedure to be a quick, virtually painless experience with immediate results.

Step 3. Post Operative Checks
Final post op checks take place, and then you are free to carry on with your normal active lifestyle, potentially with 20/20 or better vision.

We are a pioneer in the field of LASIK surgery in Rajasthan and have always tried to meet the increasing demands and expectations of patients by keeping our centre updated with the latest technology and we take immense pride in introducing this very innovative technology to not only Rajasthan but also to the north India the VISUMAX

Certain individuals with thin corneas are turned back for lasik surgery; they can be treated with epilasik. This new generation vision correction surgery uses a blunt blade to cleave or push away a thinner corneal flap to leave behind more residual corneal thickness that gives more strength and stability of the cornea. It is A device similar to a microkeratome (called epi-keratome) slides over the surface of the cornea, just underneath the epithelial layer of cells while suction is applied. The result is a hinged sheet of epithelium that is at least partially viable. It is reflected out of the way so that the ablation can take place. The sheet is repositioned and a bandage soft contact lens is placed on the eye.

It is a better treatment for eyes having high power and/or thin corneas. It causes less damage to corneal nerves, therefore a better option in dry eye problems.

PHAKIC Intraocular lenses
Phakic IOLs (intraocular lenses) are surgically implanted lenses as an alternative to LASIK in unfit eyes due to thin cornea or very high refractive power. They are specialized lenses made of plastic or silicone material, which are implanted into the eye permanently to reduce a person's dependence on glasses or contact lenses. They are called as Phakic lenses as they are implanted into the eye without removing the eye's natural lens. The phakic lens is inserted through a small incision and placed just in front of or just behind the iris.

LASER blended vision:
Recently a treatment called blended vision has been developed. It is used to treat presbyopia, a condition that occurs due to the ageing of your eye, which causes problems when looking at objects that are close to you. By treating one eye to look at images up close and leaving the other, you will be able to see properly again after a short period of adjustment.

Laser blended vision or monovision is a LASIK based procedure, whereby the surgeon corrects each eye for a different type of vision.

Laser Blended Vision adjusts each eye in different ways. One eye is adjusted to see mostly at distance and a little close up, while the other is the opposite: mostly up close and a little at distance. In most cases, the brain compensates for this quickly. It combines the two images to give much greater depth of vision, and an all-round improvement in visual acuity that means most patients can throw away those infuriating reading glasses.

Laser Blended Vision is much more effective, and easier to adapt to, than the traditional solution of monovision. Monovision uses contact lenses (or older laser systems) to make one eye focused on near and one eye focused on distance. This is a far less sophisticated solution, suitable for only around 50% of patients. In comparison, studies have also shown that Laser Blended Vision is appropriate for 97% of people. So, while we may not be able to stop the ageing process in its tracks, we can make it much more comfortable and convenient for almost everyone.

Conductive keratoplasty (CK)
CK is a non-laser refractive eye surgery designed to correct mild hyperopia and help people who are middle-aged and older reduce their need for reading glasses after they become presbyopic.

If you have clear distance vision and your only problem is poor near vision due to presbyopia, conductive keratoplasty is performed on only one eye. This creates a mild form of monovision, meaning that one eye is corrected for near vision while the other eye is stronger for distance vision.

Unlike LASIK, PRK and other laser-based procedures, NearVision CK uses low energy radio waves to reshape the cornea and restore near vision.

During the CK procedure, your eye surgeon uses a hand-held instrument with a tiny probe (smaller than a human hair) to apply low-level, radio frequency (RF) energy to specific spots that form a circular pattern on the outer part of the cornea.

Connective tissue then shrinks where the RF energy was applied, causing the circular band to act like a belt that "tightens" and steepens the cornea. This change in the curvature of the eye's surface affects the way light rays enter the eye to bring near vision back into focus.
