Cataract Eye Surgery

Are you affected by cataract impairment? This eye impairment will surely limit you from enjoying more of your vision. But you do not need to feel down now, since an eye surgery intended to treat cataract is here. Cataract eye surgery can help you clear up your vision so you will be able to have fun without being restricted or limited because of your eye ailment.

What is Cataract?

When you cannot see clearly because of some clouds blocking your vision, you might be suffering from cataract and that must be treated immediately. Having a cataract eye surgery is good; however, it also has its downturns.

Advantages of Cataract Eye Surgery

Cataract eye surgery is almost painless and the procedures to be done are all easy to do. Perhaps, it is being dubbed as the most effective yet safest way of giving you back your clear vision. It also does not have any complications right after since the risk associated with cataract surgery is set at less than 10% only. The surgery can be done only in a day and you can even go home on the same day of the operation. Your doctor might just require holding you for hours before finally releasing you and after the short recovery time, you can then do things you cannot do before because of cataract. Of course the main advantage of cataract eye surgery is that you can see again. This means you will remain independent and be able to drive safely. Your golf game may improve. You will be able to enjoy stitching.

Disadvantages of Cataract Eye Surgery

Though the risk of having complications is too minimal, it might, in some rare cases, also happen. The unexpected complications may include:

    • Blood loss
    • Eye infection
    • Reduced vision, because of lens capsule tearing
    • Fragment left over, which might require you another operation
    • Retina damage and implant dislocation
    • Inflammations

Will Smoking Affect My Eye Health?

Whenever you inhale cigarette smoke, nearly 4,000 chemicals are introduced into your bloodstream. If you are a habitual smoker, these chemicals will eventually damage your macula (the center of your retina), resulting in vision problems. Cataracts and macular degeneration are two common consequences of habitual smoking.

Macular degeneration is the leading cause of blindness in people 65+ years old in the United States, and smoking is the number one preventable risk factor of macular degeneration. In fact, according to a 2006 study in the British Journal of Ophthalmology, smoking is directly linked with 25% of macular degeneration cases that end in blindness. Secondhand smoke is also a problem. The study reveals that living with a person who smokes doubles your chances of developing macular degeneration.

Studies also show that the more cigarettes you smoke, and the longer you have been a smoker, the higher your risk of developing cataracts. Heavy smokers are up to three times more likely to have cataracts compared to non-smokers. The free radicals in cigarette smoke increase the oxidative stress in the lens of your eye, damaging important proteins and fiber cell membranes that ultimately result in the opacity of cataracts.

If you are a smoker, or have been a heavy smoker in the past and are concerned about your eye health, please contact The Khanna Institute today or call (877) 254-2662 to schedule an appointment with board-certified Los Angeles ophthalmologist Dr. Rajesh Khanna.

What Causes Cataracts?

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:

  • A blunt force injury to the eye
  • Chemical exposure to the eyes
  • Long-term smoking
  • Diabetes
  • Long-term steroid use
  • Hereditary enzyme problems or a metabolic disorder (can cause cataracts in young children)

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.

Are Cataracts Genetic?

Cataracts tend to run in families. If you have a family history of this disease, you are more likely to require cataract surgery at some point in time. However, genetics alone are not the only risk factor for cataracts. In fact, a number of things can increase your risk for cataracts including:

  • Smoking
  • Excessive exposure to UV light
  • Steroid use
  • Diabetes
  • Trauma to the eye
  • Obesity

Above all, age remains the biggest risk factor for cataracts. It is estimated that upwards of 50 percent of the population will develop cataracts by the age of 65, and up to 75 percent will develop cataracts after the age of 70. This is one of the primary reasons you should visit Beverly Hills eye doctor Rajesh Khanna for yearly visits once you are in your senior years.

Treating Cataracts

Cataracts cannot be treated. To improve vision and eliminate the problem, the cloudy lens must be replaced. Cataract surgery is the most common surgical procedure in the United States and over 99 percent of people who have had it report improved vision with minimal to no complications. Beverly Hills cataract surgeon Dr. Khanna has performed thousands of cataract surgeries and would be happy to meet with you for a one-on-one consultation to discuss the most effective way to address this common problem.

If you live in or around Beverly Hills, California and are developing cataracts, please contact the Khanna Institute of LASIK & Refractive Surgery today to schedule an initial consultation.

Cataract Surgery Complications

Cataract surgery complications are extremely rare. In fact, cataract surgery is the most commonly performed surgical procedure in the United States and it enjoys an incredibly high success rate. However, complications are still possible and Los Angeles cataract surgeon Dr. Rajesh Khanna strongly believes that all of our patients should be fully informed about the risks and benefits of this surgery prior to committing to it.

Potential Complications with Cataract Surgery

Complications of cataract surgery range from mild such as bleeding, black eye, incision leaking, and eye infection to more severe problems such as:

  • Retinal detachment
  • Cystoid macular edema
  • Secondary cataract
  • Artificial lens dislocation

These complications are rare and often treatable with additional procedures, but can, in extreme cases, lead to vision loss.

Dr. Khanna is a board-certified ophthalmologist and an active member of the American Society of Cataract and Refractive Surgery. Your procedure will be performed in an accredited ambulatory surgical center where every care is taken to reduce surgical risks and we will work closely with you after you procedure to help guard against all other complications.

For honest information about the risks and benefits of cataract surgery, please contact the Khanna Institute of LASIK & Refractive Surgery today to schedule an appointment with our Beverly Hills cataract surgeon.

What Are the Symptoms of Cataracts?

Cataracts occur when your eye’s natural lens begins to cloud up, impairing your vision. This usually happens with age. Over half of all Americans over the age of 65 will develop cataracts. At first, the amount of visual impairment may be minimal, but if cataracts are allowed to progress they may eventually lead to blindness.

Some of the most common symptoms of cataracts include:

  • Blurry, distorted vision
  • Poor night vision
  • Faded colors
  • Glare from lights that seem too bright (e.g. headlights, lamps, sunlight)
  • Double vision
  • Frequent changes in your glasses or contact lens prescription

If you are experiencing any of these symptoms, Dr. Khanna can test your eyes for cataracts during a comprehensive eye examination. This exam will include a visual acuity test, pupil dilation, and a tonometry test designed to measure the fluid pressure in your eyes.

If you have further questions about cataracts, please contact The Khanna Institute today to schedule your free LASIK screening. We serve patients throughout the Los Angeles area, with offices in Beverly Hills and Westlake Village, California.

What Are the Risks of Cataract Surgery?

Cataract surgery is considered one of the safest, most predictable, and most effective procedures of its kind. With a 98% success rate, cataract surgery can provide you with restored vision that’s potentially even better than it was before your cataracts developed. However, like all surgeries, there is still a small degree of risk involved in cataract surgery.

Some of the potential side effects of cataract surgery include:
• Inflammation or infection – Antibiotic and anti-inflammatory eye drops will be provided to prevent/treat this problem.
• Secondary cataracts – In around 30% of cataract surgeries, cells may grow beneath your new intraocular lens (IOL), making the posterior capsule that holds the IOL cloudy. Dr. Khanna will use a laser to create a tiny hole in the membrane, allowing light to pass through. This is a quick and painless procedure.
• Incision leak – If a small leak occurs in your corneal incision, Dr. Khanna will place a pressure bandage or a special kind of contact lens over the leak to seal it off and prevent infection.
• Cystoid macular edema – Up to three months after cataract surgery, swelling can occur in the macular tissue of your eye. Dr. Khanna can provide you with an anti-inflammatory medicine to treat this if it becomes a problem.

If you have further questions about cataract surgery, please contact The Khanna Institute today to schedule a free consultation. We serve patients throughout the Los Angeles area, with offices in Beverly Hills and Westlake Village, California.

Differences in Types of Intraocular Lenses (IOLs)

Differences in Types of Intraocular Lenses (IOLs)

Intraocular lens (IOL) implants are used to correct poor vision, whether it is clouded by cataracts or blurred by presbyopia.

With this type of surgery, your eye’s natural lens is replaced by an intraocular lens implant. A monofocal intraocular lens may be implanted to give you a clear point of focus, at a distance or close up.

Types of Multifocal Intraocular Lenses (IOLs)

Because of their ability to correct vision at all distances, multifocal IOLs are the most preferred IOLs. There are three main types:

Multifocal refractive

Multifocal refractive IOLs, like the Tecnis are crafted with several optical zones on the intraocular lens. These different zones allow for various focal points, which improves your vision:

  • At a far distance
  • At intermediate distances
  • At near distances

Apodized diffractive

Apodized diffractive IOLs, like the ReSTOR have gradual diffractive steps on the implant that creates a smooth transition between focal points. This IOL also bends incoming light to the multiple focal points, which enhances vision in different light conditions. Acrysof has recently improved the optical properties of its ReSTOR lenses and released a new version, known as ReSTOR +3.0D. The Khanna Institute is proud to offer this new lens which achieved patient satisfaction rates of 95 % in clinical studies and gave a fourfold increase in the number of patients achieving 20/20 vision or better.


A newer type of IOL, the accommodative, includes lenses such as the Crystalens. These IOLs have one focal point, but act like your natural lens, changing shape to move the single focal point to bring objects at varying distances into focus. Recently, Bausch and Lomb introduced Crystalens HD, which improves depth of focus to improve near vision while maintaining high quality intermediate and distance vision. Khanna Institute of LASIK & Refractive Surgery is proud to offer this new option to our cataract and presbyopia patients.

If you would like to make permanent enhancements to your vision, please call our office or schedule your appointment online today. Ventura County ophthalmologist Dr. Khanna can discuss your options with you during your free vision screening.
