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.

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.

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.
