Cataracts are cloudy areas that develop in your eye’s natural lens. Although they start out microscopic, cataracts will eventually expand to cover your entire lens, interfering with your vision and potentially leading to blindness. Most cataracts are age-related and begin to form after age 40, though symptoms are not usually noticeable until your 60s.
The clarity of your eye’s lens is maintained by the natural protein fibers within it. As you age, the structure of these protein fibers alters, causing proteins to clump together, which is what results in opacities. These cloudy areas block light from entering your eye and reaching the retina, making your vision appear foggy or dim.
However, not all cataracts are caused by the natural aging process. Sometimes, cataracts can be triggered by:
No matter what has caused your cataracts, Dr. Khanna can help you restore your vision through cataract surgery. This safe and effective procedure has one of the highest success rates in modern medicine. Your cloudy lens will be removed and replaced with an advanced refractive lens, helping you see better than you have in years. Best of all, once your cataracts are removed, there is no chance of them coming back, since cataracts cannot develop on an artificial lens.
If you have further questions about cataracts, please contact The Khanna Institute or call (877) 254-2662 to schedule an appointment with Dr. Khanna. We serve patients throughout Beverly Hills, Westlake Village, and surrounding areas of Los Angeles, California.
Strabismus is the medical term for an eye disorder more commonly called “cross-eyed.” People with strabismus cannot align both of their eyes simultaneously. One of the eyes may turn in, down, out, or up, compromising vision quality. Sometimes, strabismus only happens intermittently, during times of stress or illness. However, in other patients, it is a constant condition.
Up to 5% of children have some form of strabismus. Many of them experience double vision because their eyes are misaligned in relation to each other. In order to avoid the “ghosting” effect of double vision, your brain will completely disregard the image of one eye. If strabismus is never treated, it can eventually result in complete vision loss.
Strabismus may be congenital, or acquired later in life. Risk factors for congenital strabismus include down syndrome, low birth weight, cerebral palsy, prenatal drug exposure, and family history. Risk factors for acquired strabismus include:
Strabismus can be treated in a variety of ways, but it typically involves eye exercises, a prescription for contact lenses or glasses, and/or topical agents. Some patients wear an eyepatch to help correct the problem. If strabismus is severe enough, it may warrant surgical repair in order to properly align the eyes.
If you have further questions about strabismus, please contact The Khanna Institute or call (877) 254-2662 to schedule an appointment with Dr. Khanna. We serve patients throughout Beverly Hills, Westlake Village, and surrounding areas of Los Angeles, California.
The quality of your vision after LASIK will depend on how severe your refractive error was before surgery. Many of our patients are able to achieve 20/20 vision or better (such as 20/15), but people with a high degree of refractive error (i.e. a high prescription) may still need to use glasses or contact lenses in select situations. However, the vast majority of LASIK patients are able to enjoy 95% of their daily activities without glasses or contact lenses, and many patients experience 100% freedom from corrective eyewear.
Keep in mind that 20/20 does not necessarily indicate “perfect” vision. Some people have excellent visual clarity when reading an eye chart, but have other frustrating problems, such as glare, halos around lights, filmy vision, or dry eye syndrome – all of which can impact the quality of their vision. Our advanced Custom LASIK technology maps every unique irregularity and imperfection in your eyes in order to ensure your LASIK correction is as comprehensive as possible.
Whether or not you achieve the magic number of 20/20, you can rest assured that you will have outstanding vision and life-changing freedom from your dependence on eyewear. During your free LASIK screening, Dr. Khanna will let you know what results to expect from LASIK based on your evaluation.

Although LASIK remains the most popular vision correction surgery, alternative procedures like Refractive Lens Exchange (RLE) can provide equally excellent results for certain patients. In fact, RLE may be a better option for patients with a high degree of hyperopia (farsightedness) and/or presbyopia.
Refractive Lens Exchange involves replacing your eye’s natural lens with an artificial intraocular lens (IOL) in order to correct your refractive error and provide sharper focus. This makes it ideal for people who:
RLE is capable of correcting high degrees of hyperopia with excellent results. Visual acuity after RLE is usually better than LASIK in patients with moderate to high degrees of hyperopia.
If you have myopia (nearsightedness), LASIK is still the preferred choice for vision correction, since it does not require the removal of your natural lens. LASIK also tends to be more affordable than RLE.
If you have further questions about LASIK or Refractive Lens Exchange, please contact The Khanna Institute today or call (877) 254-2662 to schedule an appointment. We serve patients throughout Beverly Hills, Westlake Village, and surrounding areas of Los Angeles, California.
One advantage of LASIK eye surgery that isn’t often talked about is its ability to improve your peripheral (side) vision. When you are wearing glasses, your visual field is limited: you can only see clearly through the center of your glasses lenses. If you have a particularly high prescription, you are probably already aware of the fact that you need to turn your head in order to clearly see objects that are not right in front of you.
LASIK corrects the entire surface of your cornea, allowing for a complete range of vision. You will no longer have to worry about missing something that lies outside of your primary visual field. This can improve your driving safety, sports performance, and other common skills.
Using Custom WaveFront technology, Dr. Khanna can precisely map the unique contours, imperfections, and characteristics of your individual eyes. This ensures the laser treatment takes every flaw into account when correcting your vision. Some people walk away from LASIK eye surgery with vision that is even better than the 20/20 standard.

If you commonly get red or “bloodshot” eyes, Dr. Khanna can help you identify the source of the problem. Usually, bloodshot eyes are not a cause for serious concern, but they can occasionally be a symptom of a more serious eye disorder – such as pink eye (conjunctivitis), blepharitis, glaucoma, or corneal ulcers.
The appearance of bloodshot eyes is typically caused by some form of irritation, which makes the tiny blood vessels on the surface of your eye become congested with blood. A number of different factors can contribute to eye irritation, including:
Some people notice a painless bloody blotch on the surface of their eye, only to have it fade within two or three days. This phenomenon is called a subconjunctival hemorrhage. It can be caused by hypertension, blood thinning medication, heavy lifting, or a sudden severe cough or sneeze. Although this condition looks unnerving, it is generally harmless.
If your eyes seem to have a chronic “bloodshot” appearance, contact The Khanna Institute today or call (877) 254-2662 to schedule an appointment. We serve patients in Beverly Hills, Westlake Village, and surrounding areas of Los Angeles.
Contact lenses have become a way of life for many people – part of a daily routine that allows them to see clearly without the need for glasses. However, contacts should only be worn for a certain amount of time each day. If you wear your contacts too much, they can actually harm your eyes, causing a condition known as contact lens overwear syndrome (OWS).
Some of the most common symptoms of OWS include:
Overwear syndrome is most often caused by wearing contacts while you sleep, or failing to replace them with fresh lenses at the specified time. If contact lens overwear syndrome is left unaddressed, it can lead to more serious problems, including eye infections and abnormal blood vessel growth on the cornea. These new blood vessels tend to be very fragile, and can potentially leak, leaving deposits. Blood vessel growth is caused by your eyes failing to get enough oxygen, which prompts your body to produce more blood vessels in order to increase oxygen supply to your eyes.
The risks of contact lens overwear syndrome are a major reason why more patients are choosing LASIK eye surgery. LASIK can free you from your daily dependence on contact lenses. However, if you already have OWS, you will need to stop wearing contacts for awhile before undergoing LASIK so your condition can resolve

One of the most common questions people ask about LASIK eye surgery is whether or not the results are permanent. Will you have corrected vision for the rest of your life, or will your eyesight regress at some point? In order to understand the answer, you must first understand what the procedure is designed to accomplish.
LASIK permanently reshapes your cornea to correct refractive disorders – such as myopia, hyperopia, and astigmatism. Your eye will never regress back to its former shape, so in this sense, the results of LASIK are permanent. However, LASIK cannot prevent other changes to your eyes that may occur as you grow older. For example, presbyopia is a universal eye disorder that causes your eye’s natural lens to harden, losing its flexibility and its ability to focus on near objects. This is why most adults in their 40s and beyond need reading glasses. Additionally, cataracts can develop in the eyes of older patients, interfering with their vision.
Since LASIK eye surgery does not affect your lens – only your cornea – it cannot prevent these separate age-related problems from occurring later in life. In the meantime, however, LASIK can provide you with clear, sharp vision that does not require dependence on glasses or contact lenses, freeing you from the many lifestyle limitations imposed by corrective eyewear. In this sense, it is a life-changing procedure.

Keratoconus is an eye disease that progressively changes the shape of your cornea, causing light to bend incorrectly as it enters your eyes. Keratoconus can occur in one eye or both eyes. Most people with this disease find that they need a brand new prescription every time they visit the eye doctor, which can be incredibly frustrating.
Thankfully, there is a long-term solution for Keratoconus that can help you avoid the hassle of constantly changing glasses and contacts: Intacs. These small, clear plastic inserts can be implanted in your cornea to help preserve its shape, reinforcing and flattening the corneal tissue in your eye. Intacs are an FDA-approved treatment for Keratoconus.
Intacs are the ideal solution for Keratoconus because they can be removed and replaced to address different levels of correction. Since Keratoconus will continue to change your corneal shape over time, the flexibility and adjustable nature of Intacs are the best possible way to provide stable vision on a daily basis.
If you have further questions about Intacs for Keratoconus, please contact The Khanna Institute today or call (877) 254-2662 to schedule your free screening. We serve patients throughout the Los Angeles area of California.
Dry eye syndrome occurs when your tear ducts do not produce enough lubrication to properly moisturize the surface of your eyes. This can lead to inflammation, redness, a gritty or scratchy feeling in the eyes, and/or a burning sensation in the eyes. Ironically, it can also lead to excessively watery eyes, since your tear ducts will sometimes overproduce fluid to make up for the lack of moisture.
If you have dry eye syndrome and you are considering LASIK eye surgery, you will need to be screened beforehand to determine if your condition can be adequately controlled, since untreated dry eyes can interfere with healing after LASIK. Dr. Khanna will first determine if you have an underlying condition that is causing dry eyes. For example, dry eyes are often a side effect of certain medications, as well as contact lens use, dehydration, and specific eye diseases.
Once the cause of your dry eyes has been identified, Dr. Khanna will work with you to resolve the problem before moving forward with LASIK. If your dry eye syndrome is severe, he may recommend an alternative type of refractive surgery to correct your vision. The best way to find out if you are a good LASIK candidate is to come into our office for a free screening.
