Laser assisted cataract surgery

Precision and safety has increased with the advent of femtosecond lasers for cataract and Prelex surgeries.In a painless procedure lasting under two minutes the laser can make openings in the eye. It can also make relaxing incisions to correct astigmatism. More exciting and new is that the laser can now make a desired size opening of the lens bag. Further it can break the lens into multiple pieces of desired shape and size. This make it easier to remove the lens pieces with least amount of energy.

100 seniors in 1000 oaks


More than 100 seniors came to Thousand Oaks on Oct. 18 to hear a talk by Dr. Rajesh Khanna, a board-certified and internation- ally recognized Lasik surgeon who specializes in disorders of the eye.

The event at Los Robles Hos- pital was part of the hospital’s ongoing health chat series that features a variety of doctors offer- ing medical advice to community members.

Khanna discussed the signifi- cance and development of cata- racts and the most promising and advanced treatment called Prelex, a replacement of the eye’s lens.

Khanna began his discus- sion by explaining the structure of the eye and the changes that occur over time. One of the most common eye aliments is cataracts. More than 20.5 million Americans over the age of 45 are affected by cataracts each year.

A cataract is the natural dete- rioration of the lens and can cause blurry vision. If the cataract is advanced it can make it extremely difficult to see.

Common treatments that are often recommended include drops and vitamins, but Khanna said research shows that neither of those options is useful. Instead, he suggests the cataract procedure.

Forms of cataract surgery have been in existence for hundreds of years, but procedures weren’t refined until modern cataract surgery was developed about 40 years ago. Recent advances in refractive cataract and Prelex procedures take the treatment to a new level.

Laser-assisted cataract sur- gery, for example, can also cor- rect astigmatism. Cataract surgery can be performed even in the presence of dry macular degen- eration.

Khanna also talked about an- other benefit of Prelex in which presbyopic implants, such as

Restore, Tecnis and Crystalens, are used as the eye’s new lens and are able to improve its ability to see up close.

Presbyopia is a condition in which the lens of the eye loses its ability to focus on close-up objects.

People over 50 who become dependent on reading glasses are excellent candidates for Prelex surgery, said Khanna, whose new book, “Prelex,” is available on

Khanna’s website is www. His offices are in Thousand Oaks and Bev- erly Hills.

Actress Kym Whitley from the film “We Bought a Zoo” and “Animal Practice” looks into having Prelex vision correction with Dr. Khanna so she can see far, middle, and near.

Kym Whitley found all her Prelex  information from a new book called Prelex. Which is geared toward men and women over forty-five years of age who want to observe much better, or even wish to give up their own contact lenses. Prelex  is usually for individuals that are currently affected by Cataracts but this surgery will also miraculously steer you clear of the progress associated with cataracts in the future because cataracts can not grow on a prelex lens.
Prelex has evolved throughout the last several ages. Lens implant to fix cataracts have been incorporated in patients around the United states, as well as Asia, Europe, Africa, and the Caribbean. Prelex actually begun before Lasik however seemed to be handicapped by means of lack of methods. But through the decades it have been perfected and some great benefits of the particular prelex course of action verify very excellent. The task makes it possible for people to see close to, far and near.   And so the prelex course of action doesn’t just supply excellent eye-sight, but it will illuminate you from enduring cataract surgical procedures in the future in lifetime.
