    Types of LASIK Surgery

    When we talk of LASIK treatment types, we refer to the software or technology used for reshaping the cornea. Right since its introduction in early 90’s , LASIK technology has evolved in leaps and bounds and with newer advancements and treatment platforms, LASIK can now be customised to each individual eye.

    Standard LASIK

    This is the most conventional and oldest form, where the laser reshapes your cornea to remove the power, but it is associated with more risk of Halos and Glare, and lower contrast. In today’s time, standard LASIK has become obsolete and is not preferred or advised.

    SBK LASIK (Thin flap LASIK)

    In SBK or “Thin Flap LASIK”, a specially designed microleratome is used, which allows making ultra thin flaps of as low as 110 microns. Approx. 12 microns to 16 microns of corneal tissue is used for correcting one dioptre of spectacle power. By making an ultra thin flap, we save on to some microns which enhances our range for spectacle correction. Also a thinner flap means we leave more residual stroma, which means better strength for the cornea. SBK is a must in thin cornea, but it is a preferred treatment even in normal cornea.

    C-LASIK Aspheric

    This Laser treatment pattern is a form of Custom LASIK. It works on preserving the Q value or asphericity of the Cornea. Asphericity of the cornea is used to describe the shape of the cornea. A ‘0’ Q value means that the cornea has a shape of a perfect sphere, which is never the case. The normal cornea usually has a negative Q value of about -0.35 which is referred to as the Prolate shape of the cornea. Ablation of the cornea with Excimer laser results in flattening making it oblate in shape.

    Ablating the cornea by the Excimer laser to correct the spectacle power results in flattening of the cornea making it oblate in shape. If excessive ablation is done, it can affect the quality of vision.

    C LASIK or Aspheric LASIK treatment is so designed that it helps to maintain the natural Asphericity or Q value. This helps to improve the quality of vision , and the glares, haloes are lesser in Aspheric treatment. In today’s time, this is considered as the minimum standard offered to all patients of LASIK.

    Customised LASIK – Personalised Vision Correction

    If you want the sharpest vision possible after laser vision correction, a procedure you definitely should consider Customised LASIK.

    There are 2 Main types Customised LASIK.

    • Wavefront Guided LASIK (HD LASIK)
    • Topography Guided LASIK –  Contoura Vision

    FAQs

    The following are the important criteria to fulfill before considering for any spectacle removal surgery

    • Age above 18 yrs
    • Stable prescription for last 1 year
    • Overall good Eye Health

    These are the broad criteria that must be met before planning for surgery. Of course Physical examination and a thorough assessment by our LASIK surgeon will confirm your suitability for specs removal.

    About 97 % of patients are usually fit for LASIK. A patient can become a LASIK reject in case of high myopia (power more than 9D) or if the patient has a thin cornea. In case you are found unsuitable for LASIK, our doctor will discuss about alternate options with you such as ICL(Implantable collamer lens), Surface ablation (PRK), Epicontoura, Refractive Lens exchange etc.
    Once you have been examined and are found fit for LASIK, doctor will discuss and recommend the type of Laser treatment best suited for your eyes. The cost of procedure depends upon the type of treatment that you opt for , that is whether you opt for Bladefree Contoura Vision, HD Lasik(iDesign) or microkeratome (blade) LASIK, C LASIK . Remember that LASIK is much more affordable than you think…effectively the amount you would be spending on your glasses or contact lenses over next 10 years is much more than the cost of LASIK itself.
    LASIK is a procedure performed to reshape the cornea, so ideally it should be performed by a trained Cornea Surgeon. LASIK laser is not just about the machine being used. For the best results, it is important that your tests are done accurately and your treatment is planned by the surgeon after studying the intricacy of your cornea. These are best understood by a trained cornea specialist. So your treatment profile is customized and planned by our cornea specialist for the best results.Do check the credentials of your doctor, while planning the surgery.

    No, the laser procedure itself does not hurt. Anaesthetic drops (Paracaine eye drops) are put in your eyes just prior to taking you inside the OT to numb the eyes. All you need to do is stay calm, lie down on a Table inside the LASIK OT, and follow the Surgeon’s instructions. While undergoing the LASIK, you may feel slight pressure on your eye during the procedure for a few seconds. But there is NO PAIN.

    There is a fixed protocol that we follow for patient’s coming for LASIK consultation –1st Visit – PRE – OPERATIVE CHECK UP (LASIK SCREENING)To access whether LASIK is right for you, a detailed clinical evaluation needs to be done. The LASIK Screening tests involve a series of procedures like Refraction, corneal thickness analysis(Pachymetry), dry eye testing, dilated retina evaluation, Topography and Doctor’s consultation. All this would take about 2 hours. If you are a contact lens user, you are advised to discontinue wearing contacts 5 days prior to appointment, as they can affect the readings taken for LASIK screening. Once doctor has examined you and explained about the procedure, you are given a date for surgery, suitable for you. It is possible to post you for surgery, the very next day if all your tests are clear.2nd VISIT – ON DAY OF LASIK SURGERYYou are advised to come at a suitable time as communicated to you by our counsellor. It is preferred that you bring a relative or friend along to drive you back home, as you cannot drive your car immediately after the procedure. A final check of your refraction is done on the day of surgery. After completion of paperwork formalities and consents, you would be escorted to the LASIK OT.The procedure is done under numbing eye drops put in your eyes before you enter OT. No injections are used and you won’t feel any pain. The procedure takes about 10-15 minutes for one eye. The actual time of Laser treatment on your eyes is just 15- 20 seconds per eye. If you are undergoing Bladefree LASIK, you would be made to pass under two Lasers – the first is the femto second laser to make the flap and the second is excimer laser to reshape the cornea. If you are undergoing microkeratome LASIK(Blade Lasik), you would go just under the excimer Laser.After the procedure, you will be advised regarding the medications and post operative instructions and you can leave the hospital around half an hour after the procedure.3rd VISIT – 1st POST – OPERSTIVE DAY FOLLOW UPYou will be called to visit your doctor for a postoperative follow up next day after the surgery to assess your eyes and vision.

    You are advised to stop using contact lenses, at least 5 days prior to procedure.

    Put the antibiotic drops advised by the doctor in both eyes 4 times a day one day prior to surgery and once in the morning on day of surgery.

    You will be advised to start some eye drops right from the day of surgery. Instill the drops as advised by the doctor. Avoid rubbing your eyes. You can clean your eyes with a sterile cotton swab soaked in boiled water or with sterile lid wipes, making sure you don’t touch the cornea ( black part of your eye ball).

    You will be advised to wear dark goggles after the surgery, throughout the day for the first 3 days. After 3 days, you would need to wear the dark glasses only when you go outdoors, you do not need to wear them inside your house. The dark glasses help protect your eyes from dust and also helps to prevent you from touching and rubbing your eyes.

    You can have your normal food after laser treatment.

    Avoid smoking for at least 2 weeks as the smoke fumes can increase dryness felt in the eyes.

That means on 3rd day you can spend 2 hrs on the laptop, 4th day 4 hrs, 5th day 5-6 hrs and so on. By 5th Day of Surgery most people are comfortable to resume their routine.

    You are advised to avoid driving back home on the day of surgery. Most patients are comfortable to drive by the 5th post operative day. Sometimes, night driving may be a bit difficult during first few days, however the glare settles over next 2 weeks.

    For females, you are advised not to use any eye make up for 2 weeks. Threading of eyebrows and eye make up may be done after 2 weeks taking care to avoid too much pressure on the eye.

    Light activities like walking and jogging can be done the very next day. Do not do heavy exercises for 7 days. Sports activities can be done after 1 month.Avoid swimming, water diving for atleast 1 month.

    After LASIK, you would be prescribed eye drops which would need to be put as advised by your doctor. The antibiotic and anti-inflammatory drops are to be put for 3 weeks in a tapering dose and the lubricant drop are continued for a month. Some patients prefer to continue the lubricant for longer period after LASIK.

    Pregnancy and lactation are contraindication to LASIK surgery. There are hormonal changes in the body which can cause visual fluctuations and affect how the eye responds to laser treatment. So in case you are considering LASIK, it is best to plan your procedure after you have stopped breastfeeding .

    Yes, LASIK Laser surgery is safe, and is one of the most common eye surgeries done today with highly successful and predictable outcomes. But as in every surgery, there are certain potential risks that you should know about. Although these risks/complications are very rare, they will be discussed with you during your counselling.

    After the LASIK procedure, once the healing process is completed, the results gained will be permanent. There could be rare cases where blurring of vision may recur. In most cases, this happens after many years and is a result of progression of the process of myopia, which can occur naturally in any person. This could be expected in around 1-2% of treated people. If the regression, that is power is significant, a touch up procedure (LASIK enhancement) can be done after discussing with doctor.
    Like any other surgery, LASIK is also associated with some risks and complication, although rare.The minor complications include:Halos – Some patients will notice glare, halos or starburst around objects in low-light conditions. For the vast majority, these symptoms are temporary. However, others will continue to experience them for several months or longer. During pre-operative evaluation, the refractive surgeon can determine whether or not a person is at high risk for seeing long-term halos and council the patient regarding the possibility of the same.Dry eyes – There is increased dryness of the eyes typically for several months following LASIK, though some patients may experience dryness for a longer period of time. It is important to use lubricating drops frequently. If the eyes remain dry for prolonged period, there are other drops or techniques that can help. Pre-operative evaluation will help determine whether or not a person is a likely candidate for experiencing dry eyes.Infection – This is an extremely rare occurrence, with a 1 in 2000-3000 chance (similar to any eye surgery). Fortunately, as the LASIK technique has developed over the years and proven to be of great benefit to millions of patients nationwide, firmly established protocols now exist which minimize the risk of infection.
