Hi, I'm Rajesh Khanna MD. I treat eye diseases, including vision loss, detached retinas, cataracts and glaucoma.
PanOptix ® IOL is an intraocular lens designed to offer you with clear vision for near, intermediate, and far
distances without glasses after cataract surgery. It's called “The Next-Generation Trifocal” because it is
designed to provide correction at all three distances.
Today, many patients are increasingly undergoing cataract surgery earlier in life than before, and the
procedure has become an extremely rapid and refined process, in which smaller incisions, quicker
recoveries, and typically, greater visual outcomes.
Since its launch, PanOptix™ has been adopted by some leading surgeons, the technology that underpins PanOptix™ (3, 8, 9) 3 experience with the lens, their outcomes, and their thoughts on patient selection.
Over a decade now, surgeons have been able to offer presbyopia-correcting intraocular lenses (IOLs), and with them, the option of spectacle independence for presbyopes. Until fairly recently, multifocality meant bifocality: light energy is primarily directed to near and far focal points.
Multifocality, by its nature, is an optical compromise – and the trade-off of two or more focal points on the retina is associated with some level of photic phenomena, such as halo and glare.
So the challenge when designing a better multifocal IOL is to provide continuous visual acuity over near, intermediate and distance, with minimal photic phenomena, with the greatest amount of light reaching the retina for optimal contrast sensitivity.
Compared with other presbyopia correcting IOLs… There are a number of presbyopia correcting IOLs
available on the market today, each with unique optical properties. In the absence of published
comparative, controlled clinical trials, it’s hard to understand how these IOLs perform against each
other. Fortunately, the surgeons perform many hundreds of cataract procedures per month, and have
clinical experience with the most implanted presbyopia-correcting IOLs: PanOptix™, AT LISA tri,
FineVision Tri and Tecnis Symfony.
“In essence, the quadrifocal design is modified so that the extended intermediate focal
point (120 cm) is redistributed to the distance focal point for amplified performance,” Surgeons calls this
innovative diffractive lens design ENLIGHTEN™ (ENhanced LIGHT ENergy), and it results in the creation
of three foci; distance, an intermediate at 60 cm, and near at 40 cm (See Box 1, “The Technology That
Underpins PanOptix™”. At a 3 mm pupil diameter, PanOptix™ transmits 88% of light to the retina, which
is higher than other traditional trifocal multifocal IOLs, like FineVision (PhysIOL) and the AT LISA tri 839
(Zeiss) (3, 6, 10, 11).
"better...than I did before with my contacts and glasses."

He is considered a pioneer in the development of LASIK surgery.Aside from his vote of confidence as the best lasik surgeon in Los Angeles, his dedication to his patients is clear through his many achievements. He has maintained membership in ‘the American Society of Cataract and Refractive Surgery’ (ASCRS) as well as the “American Medical Association”.
Trifocal lenses are the most advanced intraocular lenses (IOLs) available today, providing clear vision for close, intermediate and far distances, without gaps in between. They are designed to enable a high degree of independence from glasses for patients leading an active life and wishing to do without visual aids.
AcrySof® IQ PanOptix® IOL is an intraocular lens designed to provide you with clear vision for near, intermediate, and far distances without glasses after cataract surgery. It's called “The Next-Generation Trifocal” because it it is designed to provide correction at all three distances.
Alcon AcrySof IQ Lens Implant. ... The AcrySof IQ lens is designed to enhance contrast sensitivity, reduce spherical aberration, and improve functional vision. The AcrySof IQ lens offers these advantages over traditional intraocular lens implants: Reduction of spherical aberration.
While most presbyopes these days choose line-free progressive lenses, conventional bifocals and trifocals have some advantages over progressives. In particular, bifocal and trifocal lenses usually provide wider lens areas for reading and computer work than progressive lenses.
Trifocals are eyeglasses with lenses that have three regions which correct for distance, intermediate (arm's length), and near vision. John Isaac Hawkins developed the trifocal lens in 1827. Trifocals are mostly used by people with advanced presbyopia who have been prescribed 2 diopters or more of reading addition.
Most people don't know that contact lenses can be bifocal, trifocal, or even progressive. But it's true: New multifocal contacts are being designed each year for people with presbyopia, a natural condition brought on by age, where the eye's natural lens stiffens and loses the ability to focus on close objects.
