At GROVER EYE LASER & ENT HOSPITAL, we believe that we can change the way you see this world without glasses or contact lenses. Various advanced laser available at our hospital provide highly scientific, safe, precise and permanent glasses removal treatment. Advanced technology helps to achieve glasses free vision, even better than 6/6 or 20/20.
Region’s most experienced Surgeon, Dr.Rohit Grover has more than 27 years of experience in Laser Vision Correction since 1995. Let the years of experience of his refractive surgery pioneer guide you into a spectacle free world with a treatment approach customized just for you that will provide the best visual outcome. While there are many different types of laser technology available with us, the choice of procedure will be made by the surgeon in discussion with you and after in-depth investigation and consultation taking into consideration your eyesight, various eye test reports, type of correction as well as occupation, lifestyle and interests.
Corneal Topography with most advanced Alcon WaveLight ® Topolyzer ® Vario Diagnostic Device, Nidek OPD Scan, Pentacam and Pachymetry (Corneal Thickness Test) are important investigations for any laser vision correction treatment. Optical Path Difference Scan or OPD Scan (Aberrometer) is a highly sophisticated test that measures and analyses any other imperfections (aberrations) in the eye’s optical pathway from the cornea, lens, vitreous cavity and retinal surface. This guides the laser to correct any high or low order aberration, corneal irregularity in the eye in addition to the correction of spherical or cylinder number. Also there is north India's only objective Accommodation measurement system for proper refractive evaluation.
A computer can only be as accurate as the input data. Strict adherence to scientific guidelines at our hospital along with high ethics, detailed and accurate pre-laser tests and technological expertise with years of cumulative experience in laser eye treatment since 1988, Excimer & LASIK LASER treatment since 1995, have made our laser vision correction results comparable to the best centers in the world. Re-correction or enhancement is needed in less than 0.1% of our patients. Doctors at this hospital do not hesitate to reject a candidate for laser vision treatment if all scientific & medical parameters are not accurately met in a particular eye.

Verification of refraction (glasses number) with Phoropter system
LASIK (Laser-Assisted in-SItu Keratomileusis) started a revolution in glasses removal technique. In this a thin slice of corneal tissue flap is created and lifted with an attached hinge. With excimer laser ablation, correction of glasses number is done on the corneal stromal bed and then the flap is replaced in original position. It is a precise, fast, safe and permanent correction for removal of glasses. Now developments as detailed below have even further refined the outcome and increased patient satisfaction.
In Bladefree or Bladeless LASIK surgery, a Femtolaser laser is used to create the flap. It creates the corneal flap by forming a layer of bubbles beneath the outer layer of the cornea with the use of rapid pulses of light. The flap is lifted, the underlying cornea reshaped with an excimer laser, and then the flap is replaced in its original position. The bladefree LASIK is safer for patients with thinner corneas, or too steep or too flat corneas who may not have been ideal candidates for LASIK with Blade. It is variously called iLasik or zLasik. The advantages of this laser are its increased precision and safety.
The femtosecond technology has recently been used for a new technique for performing laser vision correction on the cornea, that is, Refractive Lenticule Extraction, also called RELEX for short or Small Incision Lenticule Extraction or it’s abbreviation called ‘SMILE’, ‘CLEAR’ (Corneal Lenticule Extraction for Advanced Refractive correction), ‘SILK’ (Smooth Incision Lenticule Keratomileusis), etc. It uses a femtosecond laser to cut a thin lenticule (or disc) of corneal tissue within the cornea. This lenticule or disc is then manually dissected with instruments and removed through another cut on the surface of the cornea through a small incision. The net effect on the corneal shape thus caused corrects the patient’s short-sightedness (or myopia). Currently the technique is successful only for moderate myopia and astigmatism.
The unique feature of Wavefront Topography Guided Laser, Contoura Vision ® is that it studies each individual eye like an individual fingerprint and corrects accordingly. This laser is specially programmed for a particular eye and currently the latest and most advanced laser vision correction technology available in the world. This makes the treatment results far superior to that of earlier LASIK Laser and SMILE Laser.
The special Wavefront Plus with Final Fit and Multi-Point ablation by this laser system has the world’s best tissue saving wavefront technology which ablates even less than 10 microns of corneal tissue per diopter corrected and has optimized aspheric correction. With this the accuracy and safety of glasses removal laser treatment has achieved new standards at Grover Eye Laser & E.N.T. Hospital.
There is also the latest high speed eye tracker with on-line torsion error correction, automatic iris pattern recognition for best alignment of cylinder axis with aspheric zone and both the small spot & scanning slit ablation, thus taking the advantage of technical advancements on all fronts.
While Contoura Vision ® Laser eye surgery is helpful for around 80% of our patients who are hoping to have laser vision correction procedures, it is not always the recommended choice for everyone.
INDICATIONS FOR EPI-CONTOURA, CONTOURA VISION ® ASA, & CONTOURA VISION ® STREAMLIGHT The benefit is that the vision correction laser beam works right on the surface of the cornea without the need for a flap.
Patients who have thin corneas, irregular corneas, dry eyes, high powered glasses, certain occupations (eg. Professional Boxers, Armed Forces, Police etc.) or certain hobbies (such as football, karate etc.) choose to have more superficial vision corrections through surface ablation procedures.
1) Surface ablation avoids all the flap-related & Lenticule-related complications seen in LASIK & SMILE, including incomplete flaps, free caps, buttonhole flaps, flap striae, dislocated flaps, flap melts, epithelial ingrowth, DLK, incomplete lenticule, broken lenticule, etc
2) It is the safest glasses removal laser, it has NO FLAP, NO LENTICULE, NO CUT, infact NO TOUCH ! This is also very safe in case of thin cornea although the recovery takes somewhat longer. This advanced bladeless technique is used for many cases with less corneal thickness or high refractive error.

In certain cases with thin cornea or other specific medical condition we perform LASIK in combination with corneal collagen cross-linking with riboflavin (C3R or CXL) and are achieving extremely promising results. The goal of cross-linking in combination with LASIK (i.e. LASIK XTRA) is to improve LASIK outcomes in general, that is to ensure corneal stability from a biomechanical point of view and avoid corneal ectasia from a safety point of view.HOW DOES LASIK XTRA WORK?
The procedure involves a combination of Ultraviolet A (UVA) light and riboflavin (B2 one of the sub-types of vitamin B). In C3R riboflavin acts as a cornea collagen crosslinking helping agent and in addition protects the rest of the structures of the eye from scattered UV light due to its yellow colour.LASIK XTRA PROCEDURE
The patient first undergoes the planned LASIK operation where an anesthetic is applied to the eye and a flap cut into the cornea in one of two ways – either using a femtosecond laser or a microkeratome tool. The flap is lifted and the excimer laser reshapes the cornea to correct the way in which light reaches the eye. In the next step Riboflavin solution is instilled onto the cornea. The eye is allowed to soak Riboflavin for a couple of minutes after which the cornea is rinsed clean and its flap restored. A short duration ultra violet light is then directed on the eye. This has the effect of binding or creating cross-linking between the collagen molecules.
It can also be used with Epi-LASIK and ASA. The C3R procedure can also be done years after the original LASIK surgery has taken place. In other words, the two treatments don’t have to be taken together.
In advanced Multifocal laser vision correction, simultaneous correction of all distance, intermediate and near vision numbers is done. This was so far not possible with any Lasik laser system in the world and Mono-Vision correction was done wherein one eye was corrected for distance and the other eye for near.
Multifocal Laser Vision correction is very useful for patients above 35 years of age having any spectacle number and for all plus number glasses users above 18 years of age. Multifocal Lasik can be done at age 50+ also if there is no cataract or any other contraindication in the eye.
Since June 2008, Grover Eye Laser & E.N.T. Hospital is the first hospital in India to have developed and used advanced multizone Lasik creating multifocal corneal correction. Now new MULTIFOCAL LASER has also been added to correct both distance and near vision simultaneously in both eyes.
Our hospital has Objective Accommodation measurement system for accurate data input for Multifocal Laser Vision correction. With this Dr.Rohit Grover & Dr.Sujata Grover have joined the select group of only few doctors world-wide known to have developed such a technique. This also increases contrast sensitivity in most patients.
This gives much better results as compared to Presbyopic-Lasik, Presby Max, Kamara Inlay rings etc.
Multi focal laser vision correction for Presbyopia
Presbyopia is the progressive inability of the eye to focus clearly on near objects. It happens to everyone as a natural part of aging. The lens changes shape to accommodate the differences in light coming from objects at different distances. The human lens gradually stiffens and loses the ability to change shape. By the time we are in our 40s, the stiffness has progressed to the point that light rays from close objects cannot be properly focused, and we begin to experience blurred vision when we try to do tasks that require up-close focus, such as reading or needlework. Presbyopia eventually affects everyone, even people who are already farsighted (hyperopic) or nearsighted (myopic). Because people who are farsighted already have difficulty focusing on near objects, they may experience presbyopia a little earlier in life. People who are nearsighted may find that their near vision is better when they read without their glasses.
1. By MULTIFOCAL LASIK, Near Vision Correction, PRESBY-LASIK especially if you have both , a significant distance number, and also, a separate near number. Multifocal LASIK is best suited for all plus numbers even for age 18 or above and for all minus numbers age 35 and above.
2. Presbyopia is also treatable with corrective lenses. Glasses are the simplest way to regain near-vision clarity.
If you already wear corrective lenses for nearsightedness or farsightedness you may need two sets of prescriptions -- one for distance vision and one for near vision. Glasses may have bifocal lenses, in which the upper portion of the glass is corrective for distance and the lower portion for near vision.
If you don't already wear corrective lenses or you wear contact lenses, you may opt to wear simple reading glasses only when necessary to magnify near objects..
3. Contact lenses can also be used to treat presbyopia, although many people find it difficult to adjust to them. Bifocal contact lenses can be made, or you may opt for monovision lenses, in which one eye has a contact lens with a prescription for distance vision, and the other eye has a contact lens for near vision. We will help determine the best course for you.
These lenses implanted in the eye to work with the crystalline (natural) lens to correct spectacle errors. Because an ICL can correct a wider range of myopia or hypermetropia than laser refractive procedures, implantable contact lenses are often turned to as an alternative for patients unfit for LASIK surgery .
Implantable Contact Lens (ICL) are the good option in
1) High Minus or High Plus specs power with or without cylinder numbers.
2) In lower powers they are preferred when the cornea is thin and LASIK is not advisable for some reason.
ICL is of two types
Spherical (ICL) and ICL Toric (or TICL) .
Spherical ICL lens corrects only spherical power of glasses.
Toric ICL lens corrects cylinder along with spherical power of glasses .
ICL or phakic intraocular lenses, are lenses implanted in the eye to work with the natural crystalline lens of the eye to correct refractive error with or without astigmatism .
ICL can correct high refractive error in thin cornea which cannot be corrected with lasik or epi lasik laser .. implantable contact lenses are considered as an alternative to LASIK SURGERY.
The main difference between implantable collamer lenses and traditional IOLs is the fact that an ICL works in conjunction with the eye's crystalline lens .it is done in a young patient who has no cataract and an IOL replaces the eye's natural lens during cataract surgery .. IOLs are used to treat Cataract and (ICL) Implantable contact lenses treat refractive error (glasses removal) .
No. Although you may experience slight discomfort during the procedure, you should not be able to feel a properly implanted ICL.
ICL / IPCL involves implanting an ultra thin lens of a special design and the required power permanently in the eye. This lens is placed over the natural lens inside the eye, thereby correcting the spectacle power of the eye. This is generally a procedure for LASIK reject cases and should not be done indiscriminately without a proper LASIK work-up facility.

LASIK surgery is a laser procedure that corrects a wide range of near-sightedness (myopia), far-sightedness (hyperopia), astigmatism (cylinder) and Presbyopia(reading glasses for near after forty).
It is being performed for over 25 year, with millions of happy patients from all over the world. Excimer, LASIK is being done at Grover Eye Laser Hospital for past 20 years, so doctors here are very experienced.
ACCURATE PRE LASIK TESTS are important :- A computer can only be as accurate as the input data. Strict adherence to scientific guidelines at GROVER EYE LASER & E.N.T. HOSPITAL along with high ethics, detailed and accurate pre-laser tests and technological expertise with years of cumulative experience in laser eye treatment and glasses removal since 1988 and Excimer, LASIK LASER treatment since 1996, have made our laser vision correction results comparable to the best centers of the world. Re-correction or enhancement is needed in less than 0.1% of our patients.
Before deciding to undergo LASIK procedure, you should be:
There are many complications if you are wearing contact lenses on daily basis. On other hand LASIK is safer and comfortable than contact lenses.
Contact Lens patients are more prone to eye allergies and eye infections, including corneal ulcers which may lead to drop in vision permanently, as compared to a normal person.
There is no upper age limit for which LASIK can be done provided there are no other contra indications for LASIK in the eye . But after the age of 40-45 years, you will require reading glasses even after the standard LASIK laser in which only distant glasses are removed.
But in Multifocal Lasik laser which is the simultaneous correction of both distance and near vision numbers in presbyopia ( i.e. after the age of 40 years or more also) both distance and near glasses are removed. It is best for all plus numbers at all ages and for all minus,plus or double numbers(bifocal glasses) after age 40 also.
If you are not suitable candidate for LASIK you can consider ICL (Implantable Contact Lens) or Epi-LASIK, ASA Advanced Surface Ablation.
World-wide LASIK laser treatment has become the gold-standard in safety & accuracy for eye sight correction. Though being one of the safest methods for the permanent removal of glasses, there may be a few instances of over or under correction, infection, corneal haze,wrinkles and glare. The reasons for these problems are generally not technical but are due to different healing responses which vary from person to person.
LASIK complications can occur though this is very rare with modern machines & more than 20 years experienced laser surgeons at our hospital.
Yes, the effects of procedure are permanent. However, LASIK has no effect on the natural progression of your numbers, hence it should be done if your numbers are stable and age is above 18 years.
The vision recovers mostly by evening same day after LASIK and you can go back to work in few days.
Yes. Your profession or work environment will not be a limiting factor.
You will not require distance glasses in most of the cases. But after 40 years you will need reading/near work glasses, like any other normal person.
Yes, if your corneal thickness is adequate, you should be able to get rid of your glasses completely. But certain patients may have a small residual number for which usually no glasses are required.
Most Patients think that after the LASIK you cannot go back to your glasses or lenses or use colored contact lenses if required, but it is not so, and you can use contact lenses or glasses after the laser also, if needed.
Yes, usually both the eyes are done in the same sitting. This saves a lot of time for the patient and the doctor. But if you are an apprehensive patient and want to get one eye done at a time, it can be done.
