These books combine clinical expertise with patient-centered education, providing the detailed knowledge you need to make informed decisions about your vision.
Next Generation LASIK
First Edition | Available on Amazon
Discover why SMILE (Small Incision Lenticule Extraction) represents the most significant advancement in laser vision correction since LASIK. This comprehensive guide takes you through the revolutionary flapless procedure that's changing how surgeons approach myopia and astigmatism correction.
Introduction to Small Incision Lenticule Extraction and why it puts a SMILE on your face. Explores the evolution from glasses and contacts to radial keratotomy, LASIK, and now SMILE as the next-generation solution for visual freedom.
Detailed explanation of how the femtosecond laser creates a disc-shaped lenticule inside the cornea, the physics behind vision correction, and how SMILE's approach differs from surface-based procedures. Includes technical diagrams that make complex optical principles accessible.
Comprehensive candidacy criteria including age requirements (18+), prescription ranges for myopia and astigmatism, corneal thickness considerations, and conditions that may disqualify candidates. Helps readers determine if SMILE is right for their unique situation.
In-depth analysis of SMILE's six key benefits: minimally invasive approach, no flap creation, minimal dry eyes, enhanced corneal stability, and quick recovery. Explains why each advantage matters for long-term visual outcomes and lifestyle compatibility.
Practical guidance on preparing for SMILE surgery, including discontinuing contact lens wear, understanding insurance and HSA/FSA options, and addressing common fears and misconceptions about laser eye surgery.
Step-by-step walkthrough of the actual SMILE procedure, from pre-operative preparations through the 5-minute robotic laser process to immediate post-operative care. Demystifies what happens in the surgical suite to reduce anxiety.
Detailed recovery timeline showing what to expect in the first 24 hours, week, and month post-procedure. Includes activity restrictions, medication protocols, and signs of normal healing versus complications requiring attention.
Comprehensive comparison showing why SMILE is safer than LASIK across five critical metrics: no early flap complications, minimal dry eyes, faster recovery, enhanced corneal stability, and reduced infection risk from smaller incisions.
Overview of alternative vision correction procedures including PRK (surface ablation), EVO ICL (implantable contact lenses), and PIE (Presbyopic Implants in Eye). Helps readers understand when each procedure might be more appropriate than SMILE.
Authentic success stories from diverse patients including a pickleball player, Olympic diver, attorney, dental student, golfer, award-winning cameraman, CPA, and interventional radiologist. Demonstrates SMILE's impact across various professions and lifestyles.
Advanced topics including SMILE after previous eye surgeries, management of dry eyes and pterygium, and honest discussion of risks and complications with strategies for prevention and mitigation.
Frequently asked questions, concluding thoughts on SMILE's revolutionary impact, author biography highlighting Dr. Khanna's extensive credentials, and comprehensive glossary of vision correction terminology.
The Miracle of PIE
Published 2020 | Available on Amazon
After 45, presbyopia affects nearly everyone—that frustrating moment when reading glasses become necessary. This groundbreaking book reveals how PIE (Presbyopic Implant in Eye) offers a permanent solution superior to both LASIK and traditional cataract surgery for aging vision.
Explores the fascinating evolution of human vision and why eyes age. Explains the science of how light carries information, how the eye and brain work in tandem, and the inevitable changes that occur after 40 leading to presbyopia.
Detailed examination of presbyopia—the age-dependent need for reading glasses—and conventional solutions including reading glasses, bifocals, progressive lenses, and monovision contact lenses. Discusses why these temporary solutions fall short.
Introduction to Presbyopic Implant in Eye (PIE) surgery as the definitive permanent solution. Explains how replacing the aging natural lens with advanced presbyopic implants restores youthful vision across all distances without glasses dependency.
Comprehensive analysis of PIE's benefits over both LASIK and standard cataract surgery, including permanent presbyopia correction, prevention of future cataracts, potential astigmatism correction, and restoration of youthful accommodation range.
Guides readers through the decision-making process with detailed consultation information, candidacy evaluation criteria, pre-operative testing requirements, and questions to ask your surgeon to ensure optimal outcomes.
Step-by-step explanation of the surgical process, including femtosecond laser pre-treatment, phacoemulsification techniques for lens removal, and precision implant insertion. Includes discussion of both traditional and laser-assisted approaches.
Critical chapter comparing different implant classes: Crystalens (accommodating), Tecnis and Restor (multifocal), Symfony (extended depth of focus), and Panoptix (trifocal). Provides decision framework matching implants to lifestyle and visual priorities.
Inspiring testimonials from physicians, medical personnel, attorneys, educators, artists, and patients from diverse backgrounds. Demonstrates PIE's transformative impact across professions, hobbies, and daily activities requiring clear vision at all distances.
Specialized guidance for patients who've had prior LASIK, radial keratotomy (RK), or other refractive surgeries. Explains how PIE can still achieve excellent outcomes with proper planning and technique modifications.
Revolutionary concept explaining how the brain learns to optimize vision with presbyopic implants. Discusses the neuroadaptation timeline, what to expect during the adjustment period, and strategies to accelerate visual optimization.
Technical discussion of toric implants for correcting astigmatism during PIE surgery, limbal relaxing incisions (LRI), and other techniques to ensure excellent uncorrected vision in patients with corneal astigmatism.
Comprehensive overview of dry eye syndrome, its causes, symptoms, and treatments. Explains the relationship between dry eyes and vision correction procedures, with strategies for managing dry eyes before, during, and after PIE.
Honest, detailed discussion of potential complications including infection, inflammation, secondary membrane formation, and implant-related issues. Emphasizes prevention strategies and how experienced surgeons minimize risks through advanced techniques.
Real success stories from Dr. Khanna's books demonstrate the life-changing impact of advanced vision correction
"I was tired of the daily hassles of glasses and contact lenses. I play in the open-air courts. There the wind would bother my eyes when wearing contacts. SMILE appealed to me with safety and being flapless yet fast recovery. I underwent SMILE surgery at Khanna Vision Institute. Believe it or not, I was back at the court in 3 days! Within a month I left the beginner courts and started playing in the Challenge advanced courts."
"College is 99% inspiration and 1% perspiration. People forget it is 100% vision. As a student juggling work, studies and sports the hassle of remembering to take care of contacts was a struggle. Glasses fogged up from the marine layer on the coast Santa Monica. SMILE surgery has provided me with clear vision - 20/15 each eye, which is a line better than 20/20. I finally have a great work life balance."
"I have been an avid golfer from as long as I can remember. At one point my golf game started deteriorating. I thought my clubs had got spoiled, having been exposed to the extreme climate at Big Bear. So I threw them away and bought a brand-new set. The scores still did not improve. I was on to my third set when I bumped into Dr Khanna who suggested a vision check. That brought out my visual deficiency. Rather than experiment with contacts and glasses, I opted for SMILE laser vision surgery. Not only did my scores recover they surpassed previous levels. I often wonder if I had done SMILE sooner, I could have saved a lot of clubs."
"Interventional radiology requires a doctor to look at the screen, while manipulating the probe. Glasses hamper looking down at the probe and then quickly up at the monitoring screen. SMILE made my life and profession so much easier."
"I am an award-winning cameraman. My glasses kept fogging up from the high intense lights at the movie shoot. Contact lenses were worse. At that frustrating juncture, I read Dr. Khanna's amazing book. It was intriguing to learn how much common was between my eyes and the professional cameras I use. SMILE has helped me see better through the camera in all types of lighting."
