Extended Depth of Focus IOL


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.  

Symfony 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 Symfony 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.

Advantages of Symfony EDOF IOLs

  1. Give you glass free computer vision.  Monofocal IOLs do not give you this.
  2. Gives you glass free range of clear vision for intermediate distances.  Let say between 2 and 4 feet.  Traditional Multifocal IOls dont give you this range of clear vision.
  3. Lesser halos and glare compared to Multifocal IOLs or Trifocal IOLs.

Disadvantages of Symfony EDOF lenses

  1. One may still need glasses for reading or looking at the phone
  2. Some halos and glare still persist

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“.

What is the recovery after this lens surgery ?
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.

The post surgery care remains the same irrespective of which IOL is used.
