Dry Eye Syndrome: How Do Punctal Plugs Work?

If you have dry eye syndrome, you may have already heard about a common treatment: punctal plugs. These tiny biocompatible plugs – no larger than a grain of rice – are placed into your tear ducts in order to block drainage, increasing the amount of moisture on the surface of your eyes. Punctal plugs are also called occluders, lacrimal plugs, or punctum plugs.

Temporary punctal plugs are dissolvable, meaning your body will eventually absorb them after a certain amount of time – whether a few days or several months. These temporary plugs are often used after LASIK surgery in order to prevent dry eyes. Or, Dr. Khanna may use them to see how the treatment works for you particular dry eye condition before placing semi-permanent plugs.

After measuring the size of your tear duct openings (called puncta), Dr. Khanna will determine the right size of punctal plug you need. Local anesthetic is sometimes used to place the plug, but in certain cases, no anesthesia is needed at all. Once the plug is in place, you should not feel it. There may be some slight discomfort initially, but this will wear off over time, and you should be able to drive yourself home and resume your daily activities immediately after the procedure.

If you have further questions about punctal plugs or dry eye syndrome, please contact The Khanna Institute or call (877) 254-2662 today to schedule an appointment. We serve patients throughout Beverly Hills, Westlake Village, and surrounding areas of Los Angeles, California.


Am I too Young for PRELEX?

PRELEX is a type of refractive surgery that most commonly addresses presbyopia. Presbyopia is an unavoidable age-related disorder that generally starts to show symptoms when a person enters their 40s. If you are considering PRELEX as a treatment for presbyopia, you will want to wait until it has begun to show symptoms, which may not occur until you are in your mid to late 40s or beyond. However, if you are looking to PRELEX for the treatment of refractive errors, there is really no age requirement.

What’s Right for You

We have different needs at every stage of our adult lives. In some instances Beverly Hills PRELEX surgeon Dr. Rajesh Khanna may recommend this treatment at an early age, such as in your twenties. In others, he may suggest an alternative such as LASIK or PRK. This is entirely dependent on your needs and desires.

The best way to determine if PRELEX is right for you is through a one-on-one consultation with Dr. Khanna. During this consultation, Dr. Khanna will examine your eyes, listen to your concerns and help you determine which treatment will best provide you with the results you need.

If you live in the Beverly Hills area of California and would like to learn if PRELEX is right for you, please contact the Khanna Institute of LASIK & Refractive Surgery today to schedule an initial consultation.

Glasses or Intacs for Keratoconus?


Keratoconus is an eye disease that causes the corneal tissue of your eye to degenerate. Commonly beginning in the late teens and early twenties, this degenerative eye disease changes the shape of your cornea from round to a more conical shape by causing corneal tissue to bulge.

Symptoms of keratoconus include blurry or distorted vision, light sensitivity, and an increased risk for refractive errors. In its earliest stages, eye glasses and soft contact lenses can help improve vision by addressing refractive errors, though these methods will do nothing to stop the disease’s progression.


In the past, the only way to treat the progressive stages of keratoconus was through a corneal transplant. However, advancements in vision technology have brought about a safer, faster, and more effective solution with Intacs.

Intacs are tiny implants that can be placed in one or both eyes. Beverly Hills keratoconus eye surgeon Dr. Rajesh Khanna can place these semi-circular rings just below your outer corneal surface to immediately improve vision and provide a permanent solution for keratoconus.

If you are suffering from the symptoms of keratoconus in the Beverly Hills area of California, please contact the Khanna Institute of LASIK & Refractive Surgery today to schedule an initial examination.

Alcohol Consumption and the Long-Term Incidence of Cataract and Cataract Surgery: The Blue Mountains Eye Study

To assess whether alcohol consumption is associated with the long-term incidence of cataract or cataract surgery.
Population-based prospective cohort study.
A total of 3654 persons aged 49+ years were examined at baseline and 2564 were re-examined after 5 and/or 10 years. Lens photographs were taken at each visit and assessed using the Wisconsin Cataract Grading System by masked graders. An interviewer-administered questionnaire was used to collect information on alcohol consumption.
No significant associations were observed between alcohol consumption and long-term risk of nuclear, cortical, and posterior subcapsular cataract. However, after adjusting for age, gender, smoking, diabetes, myopia, socioeconomic status, and steroid use, total alcohol consumption of over 2 standard drinks per day was associated with a significantly increased likelihood of cataract surgery, when compared to total daily alcohol consumption of 1 to 2 standard drinks (adjusted odds ratio [OR] 2.10, 95% confidence interval [CI] 1.16-3.81). Abstinence from alcohol was also associated with increased likelihood of cataract surgery when compared to a total alcohol consumption of 1 to 2 standard drinks per day (adjusted OR 2.36, 95% CI 1.25–4.46).
A U-shaped association of alcohol consumption with the long-term risk of cataract surgery was found in this older cohort: moderate consumption was associated with 50% lower cataract surgery incidence, compared either to abstinence or heavy alcohol consumption.
P.S Do not drink and drive!

Tender Loving Care

We just had a wonderful gentleman who drove a 100 miles from beyond palmdale  to have Laser vision correction with our Beverly Hills LASIK doctor. After the ride he was tired and need a little pampering with an arnold palmer.(yes we serve that to our patients)
From being legally blind at -6 Diopters he went to seeing 20/40 in a matter of 10 minutes.
He still needed a little TLC or tender loving care. So our wonderful caring staff, brought out a pillow and warm blankets and converted one of the consult rooms into a bedroom for him so he could take a nap. That helped him a lot. TLC improved the vision too.
Now he was 20/20
Keep up the good work Dr. Rajesh Khanna and The Caring Staff!

Intralase assisted Intacs

Newer technology like intralase has more benefits than just fashioning LASIK flaps. At our Beverly Hills surgical center we are happy to use intralase laser from abbott medical optics. We can use this Intralase to make channel in the keratoconus cornea. In this channel Intacs ring segment can be inserted. This channel is more snug than the one made by mechanical devices. Intacs are used to lend support to the weak cornea and help restore the prolate shape. This can decrease the higher order aberrations and help the person see better.
