Good Morning, Dr Khanna here, with some very interesting questions on Lasik eye surgery, looking at it from a different angle. Some things I hadn’t thought people think and that’s how we learn more.
The first question is, “where to buy Lasik goggles” initially I got confused, like what do they mean by Lasik goggles? Then I understood. When we do Lasik surgery, we provide you postoperative kits, special glasses to wear, both during night, which are clear and wrapped around your face, so that you don’t accidentally touch or rub your eyes, and then during day time, so that no dust, sun or wind goes in and irritates your eye. I understand that some people are not able to get the same from their own Lasik providers and they’re looking to get good quality ones. So if you do online search, you can find like MHI Care, (INAUDIBLE – 1:08), solar glasses, cheapertender.com, funny name but it’s true, it is very cheap. But these have some good quality, both sun glasses, driving glasses, antiglare glasses which are very affordable.
“Can Lasik cause flutters?” No, Lasik does not cause flutters and Lasik does not treat flutters.
Which leads us to the next question, “can Lasik cause dry eyes?” Yes, Lasik can cause dry eyes, but usually it’s not permanent. When we did some studies, going back 20years ago, we used an instrument called the Osteometer, which checks the corneal sensation. We found that most of the corneal sensation returned back to normal between 3-6 months, and by 6 months people will adapt. That’s why when we are preempting dry eyes, that means we don’t want people to get dry eyes from Lasik, we start artificial tears, even insert punctual occluders in the corners of the lids to preserve the natural tears to prevent dryness from occurring. It is also very important to make sure that people don’t have severe dry eyes and that would become a contraindication. Like people with (INAUDIBLE – 2:27) syndrome who cannot produce any tears at all.
Another way we help people pre-avoid dry eyes, is that cyclosporine drops like Restasis or Zydra in indicated (INAUDIBLE – 2:41)
Our next question is, “can Lasik cure blindness?” I think that is a very general question. If the blindness legally is resulting from nearsightedness or astigmatism, yes, it can cure that. But if the blindness is from retinal detachment, (INAUDIBLE – 3:02) generation, optic nerve atrophy, then Lasik cannot help.
“Can Lasik correct double vision?” This is very important, because just yesterday, we got referred to a 24 year old young man but his neurologist, to find out the cause of his double vision. Now double vision is known as diplopia. We had to separate diplopia from monocular diplopia, where in each eye, when the other eye is closed you see double, to binocular diplopia you see double only when both eyes are open. When it is binocular diplopia, then more nerve related issues or muscle related issues are the cause. Because both eyes have to work in sync, so if the muscle is weak on one eye, one eye will move and the other eye will not and then you can have double vision. But this boy has a very clear history, that even when the left eye was closed, the right eye saw double. And the other way, when his right eye was closed, his left eye could see double too. Such things point more towards astigmatism, and that was my first impression, and we checked it his numbers, found astigmatism, put it in the trial frame and he said yes the diplopia disappeared. So that will be cured by Lasik.
“Can Lasik be done twice?” Yes, Lasik can be done twice. And when we do it the second time, we don’t even have to lift the flap. If we do Lasik today, and patient need to be enhanced to fine-tune in six months, we can just lift the old flap. But if the flap was done 10 – 15 years ago, with older instruments, it might not be wise to lift it up, and then the option becomes doing a surface treatment.
Thank you so much, keep your questions coming and watch out for answers.
So, you have gone ahead and had Lasik Eye Surgery. You may be wondering what to expect next. Are there any side effects or precautions you need to look out for or be careful of? We are here to answer all of your questions.
After having Lasik Eye Surgery it is common to have some temporary side effects. One side effect is that you might experience some tearing from either one or both of your eyes, and it might switch between the eyes. Your eyes may feel irritated and/or you might feel like there is something in your eye. There might be the occasional appearance of small red spots on the whites of your eyes. You also may experience sensitivity to light and your vision may be a bit hazy on the day of your treatment. These are all common side effects and should not alarm you. If you are experiencing any other side effect or are concerned about any part of your recovery contact your surgeon immediately.
Now that your Lasik Eye Surgery is over, there are some precautions we would like to go over with you. As with any surgery, or procedure, there are some steps you need to take to avoid injury or infection. First up, you are going to want to avoid showering or washing your hair until at least the next day. If you do decide to shower the next day you must be careful not to get any water, shampoo, or soap in your eyes for at least a week after surgery. Not that you would normally want any products in your eyes anyway! This just means you have to be extra careful. You will also want to avoid going swimming or using a sauna for at least three weeks after surgery. If you are thinking about getting your hair colored or permed, you must wait at least 10 days after your surgery. You should also avoid wearing any eye makeup for at least a week, and make sure it is clean so you can avoid any bacterial contamination or infection. You have to try not to rub your eyes for at least a month and you must sleep with your eye goggles for at least a week. You can exercise again two days after surgery but make sure to wear eye protection for up to a month after your Lasik Eye Surgery. Keep away from dirty or dusty surroundings for at least a week, and lastly make sure to wear sunglasses when you are outside in the bright sun.
By following these precautions, you will help to ensure a fast and safe recovery from your Lasik Eye Surgery.

Hi. This is Dr. Khanna, and today we are going to talk about iDesign LASIK eye surgery and why it’s one of the best LASIK vision corrections available today.
We have come a long way from the early ‘90s, when lasers were first invented to correct or reshape the human cornea. The precision and accuracy and safety has increased in the culmination of iDesign. It’s better than SMILE. It’s better than conventional, Wavefront Optimized, and even Wavefront LASIK, because it can not only correct astigmatism and other aberrations, it can do it very precisely. Let me just focus then on a little iDesign picture to show you what all it measures, and then it can treat that. If you look at this picture, it identifies the outer iris boundary. It identifies the inner iris boundary.
It identifies the hills and valleys, and also, the center of the cornea, the fixation, reflects, and the pupil, center of the pupil. These become very important when you’re dealing with esotropia or exotropia or angle alpha and kappa. Without getting you confused, all the three things I mentioned, the center of the pupil, center of the cornea, and the side reflects should be well opposed or as close to each other. The fun begins when they are separated, and that’s where we get into angle alpha and kappa. It becomes very important that the computer which is generating the treatment profile takes those into consideration and the algorithm is based on previous studies and seen where the outcomes would be the best.
iDesign Lasik does that. We don’t have that facility in conventional and other forms. Now we’re going to turn to some more interesting pictures here. If you look on this, I’ll move onto this side. These are 3-D images of the higher order aberrations, all aberrations, and the refractive map, and the point spread function of the higher. If you want to focus on in here, you’ll see it looks fairly uniform, though even from here to here versus from here to here, you see the shape is different. If you’re using SMILE or conventional, they’ll not be able to match, correct the shape, because for -5, it’ll be just making it like a sphere. Whereas in iDesign Lasik, the treatment is matched to the exact shape.
This gets even more interesting when we look at the higher order aberrations. What are the higher order aberrations? They’re called coma, etc., trefoil patterns. The lower order is what we are used to. The sphere, cylinder. But in the higher order of aberrations, if you look, how do they generate this? If you want to do SMILE or conventional, how is going to be possible to match the shape to correct this? What it means is, here on the hill and here, it needs more spots and here it needs less spots. The same thing we can see in the point spread function, that the cornea is not uniform when you compare superiorly and inferiorly, and even temporally and nasally.
If you were to put a mirror here, this spot and this spot wouldn’t match. That means the treatment profile is unique for each eye, and that can only be achieved by a really fast computer processor and special cameras which can pick up and then transmit all that information to a laser which can use that by variable spot scanning to reshape the cornea to give us the most precise vision possible.
I hope this is helpful. If you have any questions, feel free to comment or reach us at 805-230-2126. Have a wonderful day.
Interviewer: Hi guys, today we are hanging out with the laser man and we are going to ask you a few question. How are you doctor?
Doctor Khanna: Fine, thank you and welcome to this show.
Interviewer: Okay, the first thing I would like to know. Since you have been talking about laser surgery, how long does it last?
Doctor: There are two answers to that if I understand correctly. First, what I understand is how long will the procedure take. The procedure takes a minute or two per eye. The second part if I understand correctly is; will it last me a lifetime or not. In the modern technology of ‘eye design laser surgery’, it is a lifetime outcome. 20 to 25 years ago, with the other conventional lasers, it never lasted long. All infrared group was incorrect and it did not last. Without confusing you, if you are in your 20’s to 40’s and you are a good candidate for ‘Lasik’, which is a computer, controlled active laser eye design technology. The imperfections will be wiped off for life. So it is a lifetime investment.
Interviewer: Wonderful. Now that we have asked about this part, I would like to ask you what the side effects or after effects, we can have from this surgery?
Doctor: That is a very good question. We need to know about that so that we can plan ahead and in our practice we avoid those side effects. The most common being dry eye. Because we know that, we are fashion a flapping Lasik eye surgery. Whenever you do a flap whether it is by laser or by automatic microkeratomes, you end up cutting the cornea nerves. The cornea nerve supplies the eye with sensation, which helps in the production of tears. Around 3-6 months after Lasik, while the cornea nerves are recovering there can be dry eyes. We start patients on artificial tears ointment and even put in (inaudible 02:12) to preserve the natural tears. Another side effect, which used to be more common but it is less common but still occurs is ‘glaring halos’ in the post-operative period. Treating the dry eye does decrease that incidence but is somebody is inconvenienced we do prescribe yellow tinted glassed that people wear for driving bikes which cuts of the glare.
Finally, there can be under correction or over correction with eye design technology but the incidence is very little. To make sure it does not occur we have nomograms we apply and this should measure the refraction between one to three months to make sure we hit a point and brought the patient down to zero. Those are the common side effects. In some patients, especially the younger ones there can be some inflammation in the post-op period. We do start steroid drops but do not worry these are not bulk up your muscles, they are very low dose. They do help to prevent and treat the inflammation. Infection is always a treat, we do not see it commonly but we start topical antibiotics drops a day before and we continue for 5-7 days after surgery.
Those are the common side effects that we see and we work hard to prevent any of them from occurring.
Interviewer: Very nice. We have gotten to understand two things today. The first was about the laser, how long it takes and how long does it last. The second thing you were talking about was the side effects. Now that you have mentioned this few things, we just want to know if it is different for each customer or for each person?
Doctor: Yes. Not everybody is a candidate for laser eye surgery. There are certain criteria that they must fit in before we can qualify them. Age being the first, if you are less than 18 years old, you are very mature and have developed cataracts or gone beyond 50 years of age, Lasik may not be the best choice for you. In that age group between 18 and 50, we have to see if your cornea has good uniformed thickness and shape. Shape and thickness of the cornea is important and any systemic disease has to be considered. Finally, your refraction has to be stable, which is usually the case between 18 to 50 years of age. We do like to make sure, so that we do not hit a moving target. If all those qualify and your prescription had to be under 10 diopters and depending on the corneal thickness, we have to see how much tissue can be ablated so that the safety zone is empty.
To summarize, we look at age, refraction, third the stability of refraction, fourth the corneal shape and fifth the corneal thickness.
Interviewer: So it depends on every individual.
Doctor: Every individual is unique as is their eye and all of them must pass these criteria. If there is any red flag on any of that, then we cannot do Lasik for that person. We would have to switch to another kind of therapy like EPILASIK, SUPERLASIK, ICL or presbiopic implant in the eye.
Interviewer: To ensure that the eyes are going to be well kept, well maintained and well done. How do you confirm that the patient would deserve this Lasik or another Lasik that you just spoke about?
Doctor: That is another beautiful question that you have asked me. What we like to do is; we want to know what the patient wants out of the procedure. We know all the procedure we have and what they can give to the patient. Each patient is different, 18-4 it is easier because they want good distance and the eye will change its shape using the muscles to see near. If they qualify, Lasik will be the first choice but if the prescription were high for example -15, we would offer them ICL. If a patient is about 4 or definitely above 55, then ‘SUPERLASIK’ or presbyopic implant in eye is a better choice. The difference being Lasik static vision and presbyopic gives dynamic vision. What I mean by that is; there are three zones of vision.
Distance: when you are driving a car and you want to see far
Middle: which was never important 20 years ago but is definitely important now. For seeing I phones, laptops and dashboard of the car.
Close: for reading and to see small bottles
Lasik can give you one of these three. That is why they say under 50 Lasik works well, because when you see one zone distance, the muscles are strong enough to show you the other two zones by changing the shape of the lens. When you are above 50, the lens is not able to change shape. If you do Lasik, you are able to set their vision for distance, middle or near. Whereas, ‘presbyopic’ gives you all three; distance, middle and near. That is a better choice for people above 50 and Lasik is a better choice for people below 50.
Interviewer: Fantastic. Thank you so much doctor. I am personally convinced about what you have said. I would definitely come up with more questions some other time. It is great to hang out with you. I am looking forward to seeing you again and coming up with questions that the customers or people will ask me
Doctor: Thank you so much. Have a wonderful day
If you live in Camarillo LASIK eye surgery could change your life. As you drive down on the busy 101 freeway towards Thousand Oaks the marine layer may prevent may hamper your vision by clouding your glasses. iDesign lasik eye surgery may be the solution you are seeking. As of march 2018 idesign Lasik is only available at Khanna Vision Institute.
When you are shopping at the outlet malls, good vision is required to see all those price tags. Unless you want to ignore the prices and just let someone else pay the bills. For the common folks procedure is important consideration.
We offer financing options and lay away solutions to patients seeking to improve their vision. We sacrifice profits to make better eyesight more available. What we don’t cut costs on is quality and customer service. That is our pride.
We provide options other than lasik like superlasik. At least seventy percent of people who come to our office for a Lasik consult are deemed not to be candidates. We do attract many people including movie actors.
There are many factors which may require another procedure – these include age, power of your glasses, your lifestyle and sports habits. When a thorough detailed eye screening is performed with OCT and Topography more people are weeded out. The combination of shape and thickness is the most important factor for safety of lasik. If these are normal NEVER have lasik performed on your eyes. Have a second opinion with us.
Don’t worry – ICL( Implantable Collamer lens) , PIE (Presbyopia Implant in Eye), Intacs options deliver equally good results.
The first step is a short drive to our office. Come and meet us and see which vision correction procedure may be the best for you.
So drive up from Camarillo and give us a chance to help you. Living in Camarillo Lasik will enhance your life. Golf scores might finally improve.
FDA approves iDesign Lasik for mixed astigmatism. Mixed astigmatism is the most problematic of refractive disorders. The two curvatures are are unequal. Thier relationship with the length of the eye causes one curvature to be farsighted and the other to be nearsighted. With the iDesign wavescan studio system, doctors can map the most extensive visual path of the eye. This helps in generating a very accurate ma of the problems in eye which the laser can than fix.
You may not even realize you are suffering from mixed astigmatism. A person with defect of the eye is not able to see sharp inspite of glasses. The vision can fluctuate. Contact lens slip and fall off. With blinking contacts can move and make vision blurry. You may even have redness of eyes requiring visine. Headaches may be a symptom.Many patients suffer through life. Some have been turned doen for lasik eye surgery previously as laser were not adept at getting good results with this anamoly.
We at Khanan Vision Institute want to help you in your battle against mixed astigmatism. We are offering a free analysis of your eyes on the idesign wavescan studio. The best part is you even get to take your idesign waveprints home. Call (310) 482 1240 to schedule your consult.
In the FDA approved clinical study of the idesign lasik eye surgery, 91.9% of 149 eyes reached uncorrected visual acuity of 20/20 or better without glasses at 3 months after surgery. Of interest was the fact that the eyes were stable at three months.
Rajesh Khanna MD opines this approval is a giant leap in the accuracy for this complicated disease. He is one of the handful of lasik doctors in Los Angeles and Ventura counties offering this new safer lasik technology.
I hate contact lenses – redness, irritations, infections bother me. My. last infection almost made me blind!. read on…
One often faces many problems being a contact lens user. Dry eyes, irritation, and blurred vision are just a few of the inconveniences that wearing contact lenses can bring. Not to mention the hassle of having to worry about always carrying an extra pair on you and having to remove them periodically and clean them. Wearing contact lenses eliminates the need for uncomfortable and bulky glasses, but it brings a lot of difficulties as well.
If you use corrective lenses or contacts, chances are you’ve heard about Lasik Eye Surgery as a permanent vision correction option for certain candidates. With continued research and technology, ophthalmologists have developed a less invasive procedure called Super Lasik eye surgery. Instead of cutting a flap into part of the deeper, permanent corneal layer, Super Lasik is a “No-Cut” surgery that only opens a flap on the outermost layer of corneal cells, therefore making it a safer option.
Super Lasik can correct most vision conditions caused by a misshapen cornea. Patients with near-sightedness, farsightedness, or an astigmatism are eligible to have their conditions corrected with this quick laser surgery. Even if you’ve been turned down as a candidate for traditional Lasik, you can still be considered for Super Lasik, since it’s less invasive. An ideal candidate for this procedure is over 18 years old, has a stable prescription that doesn’t change more than 1.0 in a year, and has a prescription between -14.0 and +6.0. However, the ultimate decision for candidacy can only be determined in a consultation with an ophthalmologist.
The actual procedure is very simple and quick, taking between four to six minutes per eye. After numbing the eye with eye drops and marking the cornea with a ring of dye as a reference point, the eye is held open by a retainer and the surgery is ready to begin. Using an epikeratome, a vacuum-like instrument that helps to cut specific points of the cornea, the surgeon gently opens a flap of the outer layer of the cornea and applies a cool beam of light that gently reshapes the cornea, correcting the eye vision conditions specific to each patient. Then the surgeon places back the corneal flap in its original position and the cornea begins to heal immediately. Right after the procedure is finished, the patient takes home a few bottles of medicative eye drops to use for the next few weeks that aid in the healing of the cornea and most patients regain their vision within a day or two. This entire process is painless and has minimal patient discomfort.
Super Lasik is a great option for patients ineligible for traditional Lasik or prefer a less invasive, safer procedure and can create permanent 20/20 vision without the discomfort or price of correction lenses and contacts.
Lasik eye surgery proves to give a person a permanent corrected vision. This is why more people want to try this recent advancement in vision correction procedure. It is also considered as a painless and safe procedure. However, there are some things to Avoid After Having Lasik Eye Surgery Treatment
· Staring at Bright Lights
The patients of Lasik eye surgery will be given dark sunglasses just to dim the light he or she can see. This is because you should have a gentle view of the surroundings and this is also to prevent you from scratching your eyes.
One is not allowed to drive since the patient still needs to depend on other people after a few days or weeks or as long as the healing process is happening. Not being permitted to drive also prevents your eyes from having tiny debris such as dust.
· Applying Cosmetics
Cosmetics may enter under the flap of the eyes, so it must thoroughly be avoided. The healing process will not be completed successfully. Cosmetics include false eyelashes. The only allowed stuff is the eye drops since it helps in keeping your eyes moisturized.
Excreting is good for health. It may even speed up recovery. Exercising has no direct effect to the eyes of a patient having Lasik eye surgery treatment. Eye surgeons caution against vigorous exercise. Sweating may cause rubbing and dislocation of the flap. The patient must rest most of the time and must not take long in front of the television and computers.
· Drinking Alcohol
Alcohol can halt the effects of any type of medication taken by a person so it must be avoided as well after having Lasik eye surgery. It may lead to inadvertent rubbing of eyes.
· Taking a Bath in a Shower
It is advisable that no water should enter the eyes for the first few days after Lasik eye surgery. So taking a bath with a shower must be avoided. However, one can wear goggles as an eye protection.
All types of treatment surely have do’s and dont’s and knowing Things to Avoid After Having Lasik Eye Surgery Treatment can help you make your treatment successful.
Please view this video. A Los Angeles lasik patient talks about how his vision is 20/20 after lasik surgery with Dr. Khanna from the Khanna Institute of Lasik and Refractive Surgery.
Lets say you want to have Lasik and your eyes are dry. There are some special problems related to living in So Cal. It is dry. Even though we are next to an ocean, humidity is low. The tears from eyes evaporate at a fast rate. This causes dry eyes. When it rains you may have noticed the moisture increases. Your eyes become comfortable. That may be an ideal time to have lasik eye surgery.Only if that was not such a rare event. So unpredictable too. You could leave Los Angeles and move away. Easier said than done.
We therefore need to treat dry eyes.
The current options to treat dry eyes range from the simple to the exotic. Warm compress and lid massage which cost a few cents. Lipiflow which burns a hole in your pocket. Inexpensive lubricant eye ointment at bedtime. Or the costly restasis eye drops. Humidifiers, Artificial tears fit in between. What about the current rage of nutritional supplements?
Omega 3 fish oil is popular. few years ago the buzz word was flax seed oil. Either way good balanced nutrition is important. Healthy food leads to healthy eyes.
