SYMFONY IOL – EDOF LENSES
Symfony IOLs or EDOF lenses are one type of Intraocular lens which is implanted after cataract surgery. Traditional IOL solutions for treating presbyopia include Multifocals and Trifocals, which work on the principle of simultaneous vision by splitting light into multiple distinct foci, and Accommodative IOLs, which change in shape and power when the ciliary muscle contracts.
Traditionally with these technologies, the correction of presbyopia is commonly thought of in terms of the distinct distance for which functional vision is provided.
Extended Depth of Focus IOLs are like multifocals but cause lesser halos and focus more for far and intermediate range of vison. Intermediate being computer working distance.
Symphony IOL ( Made by J and J Surgicals ) is the first and only presbyopia-correcting extended range of vision IOL. It delivers a continuous full range of high quality vision with reduced incidence of halos and glare comparable to a multifocal IOL.
The Symf\phony lens, which treats presbyopia (age-related long-sightedness) is implanted into the eye during a normal cataract operation. In most cases recovery time is minimal, with patients able to return to their usual routine just 24 hours after surgery.
Unlike traditional multifocal lenses, there are much lesser glares or halos with the Symphony lens, no reduction in contrast sensitivity, and it has a special defraction grating, making it similar to a traditional lens implant but with the added benefit of a reading prescription.
There are indian Extended Depth of Focus lenses available too and show very good results.
Please consult your doctor to know more about the lenses and if you would be a right candidate for this lens. Also here is a short article on “The best cataract lens“.

Frequently Asked Questions
These lenses like the multifocal lenses are premium lenses and thus fall in the higher bracket as regards the cost of surgery. The price varies between an indian and foreign lens. Please write to us to know more.
The recovery after most cataract surgeries is independant of the lens. Patients see much better the same or the next evening and many of our patients tell us in a few days that they are seeing better than the other eye.
