Beyond Lasik – Prelex Eye Surgery
Beyond Lasik: Eye Surgery for the Rest of Us – Prelex
By Veera Mahajan
Dr. Rajesh Khanna in Los Angeles, knows a thing or two about the eye. As a practicing optical specialist, he’s helped countless patients finally put glasses and contacts to rest. But is surgery right for everyone? Are there options beyond the famous “lasik surgery”?
Dr. Khanna explains in his new book Prelex, the inner workings of the eye and the changes that happen as we age. “At a certain point people pass the Lasik stage” explains Dr. Khanna, “Mostly it’s the baby boomer generation. Their eye just can’t handle the surgery anymore.”
Enter Prelex, or Presbyopic refractive lens exchange. Dr. Khanna summarizes:   “Presbyopia is when the muscles of the eye are not able to move the lens. When we see far then near, the eye power has to change.  As the eye gets old, the lens becomes thicker and the space for it decreases. By 45-50 years of age the lens is not able to accommodate the thickening of the muscle. So, it starts affecting the eye sight, first the near and, gradually, the far.”
Basically the eye can’t handle the constant stress of looking from a book to, say, a clock across the room. So how can Prelex help?
“With Prelex we can correct everything. Far sightedness, near sightedness, stigmatism, you name it” explains Dr. Khanna. He stresses that it is nothing like Lasik. “Lasik is a superficial surgery.  Prelex requires the implant of lenses. Lasik does not. It’s much more detailed.” It takes a much higher degree of skill which makes it more expensive but according to Dr. Khanna it’s worth it:
“Imagine never having to worry about cataracts again. It’s pretty incredible. We take out the old lens and put in a new one. The new lens never wears out, so they never change shape. It’s not bi-focal, it’s beyond that.”
Dr. Khanna is one of the few eye surgeons who perform this new and highly effective surgery in LA. He quoted Lasik at $2750 per eye and said that Prelex is 3 times the cost of Lasik at $7500 per eye.  There is a difference in the price because there is big difference in the two procedures. While Lasik is done in a clean manner, Prelex is done in a sterile manner.  It is done in an operating room and a much higher level of skill is required to perform Prelex. All that adds up to the higher cost.
But with Dr. Khanna, this price includes surgery center fee, lens fee, maintenance and everything after the surgery. He includes fine tuning and follow up, which most doctors don’t.
“I like to give a personal touch to my patients and their satisfaction is my goal” says Dr. Khanna, “That’s what’s worth it to me.” He guarantees his work. As long as he is practicing, his patients can come back for fine tuning to him.  His goal is for the patient to be happy and satisfied.
He uses different lenses based on the life style of the patient. For example he has lens that can stand trauma, for a patient who is into martial arts.
He realizes the cost is high. So, for special cases, he will consider genuine financial difficulties.
In general Lasik is 7 times safer than contacts.  With Dr. Khanna, who has done thousands of Lasiks and has the latest equipment, Lasik is 100 times safer than wearing contacts. If you have had infection twice due to contact lenses, he thinks you should consider Lasik and if you are older than 40, Prelex is your best bet.
The risk of this surgery is minimal and less than getting hit by a car while driving in LA.  He teaches how to pro-actively prevent infections, complications, etc.  Patient satisfaction is so important to him that gives all his patients his cell phone number.  He wants to be available to them when they need him.
Dr. Khanna encourages patients to come in and decide which procedure is right for them. You can read his book on his blog, as well as learn other fun facts about eye care.
Dr. Rajesh Khanna
Prelex, The Book explains what are the different components in the eye and what differences occur as we age.   Near and far sightedness, stigmatism and estopia (old eye).  Baby boomers pushed Lasik a lot. But they have crossed or passed the Lasik stage now.

Lasik or Prelex? – Dr Rajesh Khanna Answers

The book ‘Prelex’


Rajesh Khanna, MD 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. He 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

Khanna has just released a book titled ‘Prelex’ which is a relatively new procedure  which was approved by  the FDA  in 2005 and the results of which since then  have been excellent when done  by  skilful eye caregivers.  The surgeon explained that  a few years ago Lasik became extremely popular  but 7 or 8 years ago it became evident that it did not work very well for everybody, especially those over the 45-50 age bracket. The Prelex procedure allows individuals over this age to see near, middle, and distance in each eye (not monovision) without the use of glasses or contacts.

According to Dr Khanna, Lasik was suitable for not more than 30-40 million of the US population whereas Prelex would be the preferred procedure for over 132 million people in the country.  He added that everyone over 45 should be knowledgeable about this procedure and when he found 3 or 4 years ago these patients were not receiving the proper advice he decided to write a book which is reported to be selling very well.

The book explains in simple terms that in a normal eye adjusts its focus because the lens changes shape but with age it hardens and loses the ability and therefore needs replacement. Till now there were no lenses to mimic the human eye but now with nanoengineering technology it is possible to create lenses which can see far and near.

Dr Rajesh Khanna

Lasik has certain disadvantages when compared to Prelex in that Lasik could develop dry eyes and there is a certain loss in depth of perception and vision can still change.  In some older patients they even develop cataracts. The advantage of Prelex over Lasik is that it is a permanent fix and vision will not change for the rest of one’s life, cataracts will not develop and one can see far and near without losing depth of perception and vision will actually improve with time.

Because of the fact Prelex is done in a sterile surgical suite and under anesthesia the cost of the procedure is higher than. The charges vary from city to city but as an example the average cost of Lasik in Beverly Hills would amount to $5,000 to 6,000 where Prelex would run from $12-15,000 for two eyes.  The down side is that it is not covered by insurance but under certain circumstances Medicare does cover part of the charges.

Lasik surgery takes about 2 minute per eye whereas Prelex takes between 7 and 8 minutes. While Dr Khanna laughs and states some patients would like to get straight back to work, he does not recommend it.  Also in accordance to US standards there is a recommended gap of at least 2 weeks between the procedure on the two eyes.

The book also describes how to be an educated consumer by learning to understand what qualities to look for in a Prelex surgeon, how to select an ideal facility and the questions to ask. This is important because only a handful of eye doctors have the skill to do it to perfection.  Dr Khanna added such specialists need to already be good lasik, cataract and lens exchange surgeons.

Prelex can also be performed successfully on those who have already had Lasik or radial keratotomy procedures.

Acorn reviews Prelex book

Dr. Rajesh Khanna, right, an internationally recognized LASIK
and refractive vision care specialist, has written a new book. Prelex, his
first book, explains the Prelex procedure in its entirety. He also explains
the basics of the human eye, vision and how vision changes over time.
LASIK is a term that most are familiar with and needs little explanation.
Prelex, however, is a highly advanced procedure that can dramatically
improve the vision of people over age 45. Khanna explains presbyopia,
which usually begins around age 40. Presbyopia is the inability of the
old, thick, resistant lens to change shape and focus power. Rather
than suffering from poor vision, unsure of the cause, readers are now
able to understand exactly what is occurring, learn about Prelex and
how it can improve their lives. Prelex is available at

Dr. Rajesh Khanna Hosts a Health Chat Sponsored by Los Robles Hospital and Medical Center

Thursday October 18th, over one hundred well educated senior community members came out to hear a speaking engagement featuring Dr. Rajesh Khanna. The event was held by Los Robles hospital and medical center, and is a part of their health chat series, which features a variety of local doctors, that can offer valuable medical advice to community members. During the informative health chat, Dr. Khanna discussed the significance and development of cataracts, and the most promising and advanced treatment, called prelex.

Dr. Khanna began the discussion by explaining the structure of the eye and the changes that occur overtime. 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.

So what is a cataract? A cataract is the natural deterioration of the lens. This process can cause blurry vision, and if the cataract is advanced, it can cause the patient severe vision difficulty. Common treatments that are often recommended include drops, and vitamins. Dr. Khanna states, that there is extensive research showing that neither of these options are useful. Instead, Dr. Khanna suggests the cataract procedure. Cataract surgery was invented over 2,000 years ago, and has since been refined. About 40 years ago modern cataract surgery was developed. Recent advances in refractive cataract and prelex procedures were explained during the health chat. Dr. Khanna also talked about presbyopic implants, such as restore, tecnis, and crystalens. This interactive session led to a lot of questions from the listeners.
