Lasik Laser

LASIK is the safest FDA approved technique to get rid of spectacles and experience the world in a new way. LASIK and other refractive surgeries (PRK, ICL) are a group of simple, effective, safe and painless procedures to get rid of glasses.With bladefree customized iLASIK technology we can achieve excellent 6/6 vision (20/20) in most cases and also excellent visual quality (high definition vision) with minimal glare.

LASIK (Laser-Assisted in Situ Keratomileusis), commonly referred to as laser eye surgery, is a type of refractive surgery for the correction of myopia, hyperopia, and astigmatism.

Drishti Eye Centre the premier eye care centre in Faridabad is pioneer in Lasik surgery. Equipped with the STAR S4 IR Excimer Laser System. The system is designed to bring Advanced CustomVue laser vision correction to life.

Featuring Variable Spot Scanning technology and Variable Repetition Rate pulse-packing algorithm, both proprietary to AMO, it reduces thermal effects on the cornea, allowing the surgeon to perform the procedure quickly and effectively, while maximizing patient safety.

The STAR S4 IR Excimer Laser System, at Drishti Eye Centre, the first of its kind in the country, is among the most advanced Excimer Laser machines available today and is considered the gold standard amongst excimer lasers. This means, that LASIK surgery has now become safer and more accurate than ever before.

• This is a US FDA approved excimer laser system and is the most popular Excimer laser in USA (70% of all Excimer lasers).

• Millions of laser procedures have been performed with it worldwide with 98% of patients having achieved 6/6 or better vision without glasses.

• It removes minimal corneal tissue – can safely correct even higher powers.

• Its unique ActiveTrak 3-D eye tracker ensures accurate laser delivery and compensates for minute eye movements during the procedure.

• Its individualized treatment option (Advanced CustomVueTM treatment) provides unsurpassed quality of vision, trouble-free night driving, and freedom from glare and haloes. This is aided by Variable Spot Scanning (VSSTM), which corrects the minutest of optical imperfections, the 3-D Eye Tracking device and the new Iris Recognition (IR) software, which ensures accurate correction of high cylindrical spectacle powers.

The STAR S4 IR Excimer Laser System therefore provides your doctor with the best possible treatment options for you.

Advantages Of Lasik

  • No hassles in swimming.

  • Quick return to usable vision.

  • No hiccups of broken or lost glasses.

  • A quick procedure with rapid recovery.

  • Unhampered participation in active sports.

  • It does not involve any injections or sutures.

  • Predictable and permanent correction of refractive errors.

  • The goal is to reduce or eliminate dependence on glasses and contact lenses.

  • Dramatic improvement in vision without glasses compared to pre Lasik vision without glasses.

  • No blurred vision due to fogging of glasses during rainy season or coming out of AC environment.

Refractive Errors & Lasik Laser

The eye works in a similar way as a camera. To get a clear picture the lens of the camera focuses the rays of light on the camera film in a similar way, the light rays get focused on the retina(the inner most layer of eye) with the help of camera (the anterior surface of the eye)and lens of the eye. The inability of the eye to accurately focus these rays of light coming from a distance, onto the retina is called refractive error. This condition may be either because the eye is too short or long in length, or because the refractive power of the cornea or lens is not optimum. There are types of refractive errors.

MYOPIA (Near-Sight)

The light rays are focused in front of the retina, either because the eye is too long or the power of the cornea and lens is more than required, distant objects are seen clearly. Minus glasses are needed to correct this condition.

The light rays are focused behind the Retina, either because the eye is too short or the power of the cornea glasses is needed to correct this condition.


The person strains the eyes to see objects clearly. Plus the light rays do not get focused evenly to a point, usually due to the cornea the eye being more curved in one direction than the other cylinder lenses (with axis) are needed.

Frequently Asked Questions

Lasik involves raising a very thin corneal flap with the help of a special automated and very precise blade. After this the excimer laser treated is applied to the rest of corneal surface to change its shape and thus correct the refractive error. The parameters used for conventional Lasik are based on the refractive error of the patient. The raised flap is then positioned back, where it sticks without the need of any suture.

The person must be 18 years or older with a stable power. A contact lens user must discontinue the use of contact lenses at least 2 weeks before the procedure. A detailed eye check-up is done to look for suitability for the procedure. Before the laser is done the eyes are checked with special machines to determine the exact power. The corneal mapping is done and corneal thickness is measured. In patients with high minus power a special retiona, which may need to be treated before the LASIK is performed. The LASIK laser is performed only after ruling out any contraindication and suitability of the procedure.

In case the patients is not suitable for LASIK due to thin cornea, other options like phakie lenses ICL, clear lens extration with Multifocal IOL, PRK etc. may be considered after detailed checkup.

LASIK is one of the safest procedures performed over all over the world. The safety profile of LASIK procedure is very high. The LASIK machine is mostly automated and operated by highly skilled refractive surgeons thus increasing the success rates.

NO. There is no pain during or after the procedure. The patient may feel some pressure over the eye which lasts for a few seconds.

The refractive errors may be treated by either of the following ways:

Glasses: This is the simplest and most popular way of correcting refractive errors.

Contact lens: This option is cosmetically much better. However, it requires though maintenance and cleaning of the contact lenses, and regular eye checkups. There is also a sight risk of allergy and infection to the eye, if the contact lenses are not cleaned properly.

Refractive laser surgeries: Get rid of the need for glasses and are increasingly becoming popular with the advent of safer and more predictable laser treatments.

In younger persons, the lens has the capacity to increase its power to focus for nearer objects (accommodation). Presbyopia is a part of normal aging process, where the lens progressively loses this capacity of accommodation. The distance vision may be normal, but the near vision becomes blurred with age greater than about 40-45 years. This is correct by wearing reading glasses (plus) for the near work. One must remember that refractive laser surgeries only correct the refractive error (myopia, hypermetropia and astigmatism), but do not correct the presbyopia.

A special form of laser (Excimer Laser) is used to correct the refractive error by changing the shape and thus the power of the cornea. It is a very precise laser and can change the shape of the cornea with an accuracy of more than a thousand of a millimetre. The sophisticated laser machine automatically delivers the required laser treatment based refractive error of the patient.

The most common options available are:

PRK : It is being used less commonly now days.

LASIK: This is most popular form of laser treatments.

LASEK (or EPI-LASIK) : This newer form of treatment may be suitable in some selected patients with very high power.
