In Myopia or short sight, the image gets focused before the rays reach the retina. The eye is too long or its focusing power is too strong. Distance objects appear blurred.
In Hypermetropia or far sight the image is not yet focused when the rays reach the retina. The eye is short or its focusing power is weak. Objects both at distance and near may be blurred in this condition.
In Astigmatism the irregularly shaped cornea make the image unclear. Parts of the image are focused at different levels.
Presbyopia occurs after 40 years due to aging process. Near objects are blurry. It occurs early in Hyperopes and later in Myopes.
• Myopia (Short sight)
• Hyperopia (Long sight)
• Presbyopia (Chaleese)
The human eye performs better than a modern digital camera. The cornea and crystalline lens focus an object on the retina. The high resolution image is transmitted to the brain through the optic nerve by a stream of micro electrical pulses. Good eyesight depends on the integrity of all these structures and their functions. Some eyes cannot perfectly focus the image onto the retina due to variation in the length of the eye or shape of the cornea.
LASIK stands of “Laser assisted in situ Keratomileuses”. Performed first in 1990 at United States, LASIK today offers one of the highest patient satisfaction rates among all medical procedures on the body!
LASIK uses Excimer LASER which is an extremely controlled, tiny and specialized beam of ultraviolet light. The computer controlled LASER beam reshapes the corneal curvature in a highly precise and predetermined pattern so that it can now focus the light properly on the Retina.
In LASER vision correction, after surgical cleaning and draping, the eye is made numb with eye drops. A very thin flap is created on the front surface of the cornea using a Micro-Keratome or Femtosecond LASER. This thin flap is folded up and Excimer LASER is applied, to rectify the refractive error. The flap is then replaced back to its original position. So the surface remains unaffected, and gives maximum comfort during post LASER period.
In ASA (Advanced surface ablation) the Excimer LASER is applied on the surface of the cornea after removing its epithelium. As a flap is not raised, it is particularly ideal for thinner cornea, higher powers and to custom treat irregular corneas with high aberrations.
Karthik Netralaya offers the entire range of modern LASER vision corrections. Wavefront
Optimized Treatment, PRK (Photo-refractive LASER Keratectomy), LASEK, EpiLASIK, ASA
(advanced surface ablation), FEMTO-second LASIK, PresbyLASIK, F-CAT (Oculyzer guided
treatment), PTK (Photo-therapeutic LASER Keratectomy) etc. are some of them. Specialized protocols for post Cataract surgery residual refractive errors, Angle Kappa customisation, post RK hyper-metropia, ASA & LASIK plus for forme frustae Keratoconus, post refractive surgery glare and starbursts etc are offered too. Your LASIK specialist will advise the best treatment that suits your eyes.
We use Allegetto Eye Blueline 400 ExcimerLASER with its extensive range, including Wavefront analyzer & Pentacam HR Oculyzer guided ablations. It is acknowledged to be the most advanced German made CE & US FDA certified LASER systems. With a Super high speed eye tracking rate of 400 HZ, this WaveLight’s LASER is one of the fastest. Eye tracker precisely directs the LASER beam to follow micro eye movements & neutralize them so as to assure high patient safety. This high speed Laser treatment minimizes stromal dehydration and offers precise results. The unique Gaussian beam wavefront profile ensures smoothest surface. The ablation thickness per diopter is the least amongst LASIK machines and allows maximum residual corneal thickness. We have the longest experience in using these advanced systems, and all this amounts to unprecedented safety, consistency & accuracy.
You have an option of either Amadeus 2 Microkeratome or FS-200 Femto LASER to create your perfect corneal flap. Microkeratome creates a slight Meniscus shaped flap while the Femto LASER creates a uniplanar flap with uniform thickness throughout. While the latter may be better due to its accurate predetermined thickness setting, both the techniques offer ultrathin flaps, allowing highest corneal preservation in those eyes with thin corneas or need high power corrections.
The Blade free FS-200 Femto LASER creates a uniplanar flap with uniform thickness throughout. It allows the surgeon to create a highly customized flap by adjusting its size, shape, cut angle and hinge to suite your ocular parameters. Complications like button hole and free flap are totally avoided by this advanced technology. The architecture of the flap improves the adhesion and reduces the chances of epithelial ingrowth
(Surface cells migrating under the flap).It creates ultrathin flaps which is essential for thin corneas and high powers.
All LASER procedures need no injections, have no pain, & needs no stitches or bandage. You will be very comfortable throughout the procedure.
The Allegreto Wavelight LASER first offered the modern Wavefront Optimization so as to minimize the changes that occur to the natural prolateness of the normal cornea. The spherical aberration is least affected and so glare, halos and degradation of night vision are maximally avoided.
Old Excimer LASERs use a broad beam with an aperture controlling the amount the beam diameter. Gaussian profile beam at high speed eliminates the disadvantages of broad beam LASER.
Every person becomes presbyopic and dependent on reading glasses at the age of around 40 years. PresbyLASIK is an excellent solution to decrease this dependency. The corneal surface is made multifocal by changing its asphericity, so that both far and near objects are focused on the retina. This can be combined with micro monovision for maximal benefit.
Pre LASIK assessment is best done few days before your LASER procedure. This includes extensive analysis of your eyes to ensure if it is safe for you, and to plan the exact procedure. Pentacam HR, Oculus Keratography, Corneal and internal wavefront analysis by NIDEK OPD Scan, Refraction with and without cycloplegic drops, dilated Vitreo retinal examination, Dry eye evaluation, Pupillometry, Optical Axial length measurement etc are some of the tests performed, You will have blurry vision for about a day or 2. You may not be able to drive back home, so preferably bring someone along with you, which also helps you to take instructions.

Fix up the date for LASIK and than go through blood tests, ECG, Physician’s check up, Pre LASIK assessment & counseling.. Bring all your old medical records and medicines you are taking. Tell us your past & present illnesses, surgeries & allergies
One day before refractive procedure
Do your routine work. Trim nails and remove nail polish. Avoid cosmetics on the face & eyes. Use eye drops and tablets as advised. Continue all your regular medications. -Wash your face with antiseptic soap for 5 minutes before sleeping. Use washed towel, bedspread and pillow cover.
The most sophisticated equipment are used in our bio-clean LASIK operation Theatre. Strict aseptic protocols are meticulously followed. Each surgery is completely isolated from others. High quality medicines, supplies and disposables are used.
LASIK procedure is totally painless and extremely quick. For this ‘Eye drops technique’ no injections are needed! Eye will be numbed by few eye drops. Please remain quiet & calm during surgery. Do not hesitate to talk to the Surgeon for any clarification, or if wish to move or cough. The eye tracker stops the LASER if you move your eyes and than restart once you are steady! You will be awake and extremely comfortable during the procedure. You may experience slight pressure over the eye and vision black outs during certain steps. Though actual LASER takes seconds to minutes per eye, you will be inside
the OT for about 20 to 30 minutes.
closed from the next day after LASER vision correction. Gently dab the eyes with a clean washed towel. Don’t rub, press or massage the eyes!
The goal of any refractive surgery is to eliminate your dependence on glasses and contact lenses. If you have correctable 6/6 vision with your glasses or contacts, you certainly have the potential to achieve it with LASER vision correction.
Allegretto 400 HZ LaASIK is pioneered to offer Gaussian profile LASER beam. It is designed to offer high quality wavefront optimised treatment, preserving the corneal asphericity as close to normal as possible. The corneal ablation is least per given power when compared to its contemporaries.
LASIK is definitely permanent and the powers eliminated will not come back! The effect of LASIK does not wear off. But it is important to realize that a person’s eye length and parameters can change internally. The procedure is therefore done after the major eye changes have occurred and the power remains stable for more than 1 year. LASIK is not recommended in children where the eye is still growing, or in adults in whom
the power is still changing. Rarely, the powers could change due to instability of the cornea (due to inherent reasons, pre existing Forme frustae Keratoconus or thinning induced by treatment) or continued growth of the eye length.
The actual LASER application takes just about 2 seconds per diopter of myopic correction! The whole procedure inside the OT takes just about 10 to 15 minutes per eye.
In monovision treatment, one eye is corrected for distance vision and the other eye is corrected for intermediate vision. This works extremely well for patients above 40 years who have presbyopia. This procedure can postpone usage of reading glasses by several years. A trial will be given to you in the OPD to see if you can opt for Monovision.
LASIK is performed under numbing eye drops. It is completely painless. Several measures are taken to make the entire experience comfortable for you!

This is to personally thank Dr. M.S. Ravindra and the whole staff of Karthik Netralaya. Such great services were rendered from the time I enquired about the LASIK surgery till the post LASIK clarifications. All the staffs and the doctors were very clear and open towards any kind of doubts I had regarding LASIK. My thick glasses and lenses that I was using since past 16 years thwarted me from doing many things I wanted in life especially water sports! I use to swim with my lenses on and a big swim glass on top which use to be very uncomfortable. Now I am free from all these and have nothing to worry about the lenses, solutions and glasses. Also I don’t need to carry them everywhere I go! All thanks to Dr Ravindra and the staff of Karthik Netralaya once again. And to add to all this they have a very clean, well maintained premises and pleasant ambience. From my side the doctor and Karthik Netralaya is 100% recommended!!

I am Lakshmi and I work for IBM as senior software engineer. I tried to locate the best laser treatment in Bangalore and I got this reference from my CHN eye doctor. Upon further enquiry I found that most of my colleagues got LASIK done with the same clinic. I got my LASIK done at Karthik Netralaya, Bangalore in 2010. I was very much scared of the procedure before I approached them. The doctor was very very kind enough to explain me the procedure. His patience levels are very high and he made me very comfortable through-out the procedure. My overall experience with Karthik Netralaya is EXCELLENT.
Thank you doctor and your whole team!
