Lasik specialist writes book on benefits of ‘Prelex’

“Prelex,” above and Khanna, below.
Beverly Hills Lasik surgeon Dr. Rajesh Khanna decided to follow in the path of Doctors Chopra and Gupta, and compile a book titled “Prelex,” which is receiving rave reviews on Amazon. As it is discussed in the book, the Prelex procedure allows individuals over 45 to see near, middle and distance in each eye (not monovision) without the use of glasses or contacts. This procedure also prevents the development of cataracts. Patients describe Prelex as, “miraculous” and “life changing.” According to Khanna, the book is aimed at all people above 45 years of age including baby boomers and seniors.

Khanna is board certified by the American Board of Ophthalmology. He has specialized training in LASIK, Prelex, Cataract and Corneal surgery from the University of Cincinnati. Khanna is known as the Lasik surgeon to the stars, as he has performed over 10,000 vision correction procedures on many Olympic medal winners and Hollywood personalities like Disney stars Brenda Song and Corbin Bleu, “Hercules” Kevin Sorbo, UFC champion fighter Bas Rutten, and Butch Patrick who played Eddie Munster. He also performs Intacs Surgery for Keratoconus. Khanna is a voluntary member of the UCLA faculty, as well as of the American Academy of Ophthalmology and the American Society of Cataract and Refractive surgery. The Khanna Vision Institute has centers in Beverly Hills and Westlake Village.

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.
