#1 Detailed Information About EDOF lenses | Dr Kashish Gupta

EDOF lenses is an Acronym for Extended Depth of Focus. It is a type of intraocular lens (IOL) used in cataract surgery to replace the standard lens in the eye.

How is EDOF different from standard IOL lenses?

How is EDOF different from standard IOL lenses? EDOF IOLs differ from traditional IOLs because they don’t have a set focus distance. Instead, they use a unique design to give a clear vision from near to medium distances. This means that people who get EDOF IOLs might not need glasses as much to do everyday things like reading, using a computer, and driving.

What are the most popular EDOF Lenses available in the market?

The most popular EDOF lenses available in India are:
  • Johnson & Johnson Acuvue Oasys with Transitions – This lens is designed to provide clear and comfortable vision in varying light conditions.
  • Bausch & Lomb Ultra for Presbyopia – This lens offers a seamless transition between distance, intermediate, and near vision.
  • Alcon Dailies Total 1 Multifocal – This lens provides a natural-looking vision for people with presbyopia.
  • CooperVision Biofinity Energys – This lens is designed to reduce digital eye strain and provide clear vision.
EDOF lens in Cataract Surgery: A new type of IOL called EDOF (Extended Depth of Focus) has been introduced to the Indian market. This type of IOL claims to improve the quality of vision for people with cataracts. In this essay for an Indian audience, we will talk about how much EDOF glasses cost, how well they work, and how they are used.

How does an EDOF lens work?

How does an EDOF lens work? The EDOF lens design typically involves a combination of multiple lenses, each with a different refractive index and curvature, arranged in a specific configuration. In addition, the lens design is optimized to create a particular phase profile, resulting in a unique point spread function that provides an extended depth of field. The EDOF lens can be designed to work with both monochromatic and polychromatic light. In monochrome applications, the lens is designed to correct for spherical aberrations and other optical aberrations, which can cause blurred images. In polychromatic applications, the lens must correct for chromatic aberrations, which can cause colour fringing and other distortions.

Why is the EDOF lens becoming the popular choice in Cataract surgery?

Why is the EDOF lens becoming the popular choice in Cataract surgery? EDOF lenses are relatively new, and cataract surgery does not use them often. But they are becoming more common because they might help people see better and lessen the need for glasses or contacts. Most of the time, EDOF lenses are put in during the same surgery as traditional mono-focal lenses. The significant difference is the type of lens that is used.

Which is the best Surgeon for EDOF lens Implant?

Most surgeons offering EDOF lenses have had special training and practice with them because they need to be measured and placed more accurately. Patients who want EDOF lenses should talk to a surgeon who has worked with them before and can give them a complete evaluation to see if they are a good candidate.

What is the Price of an EDOF lens?

EDOF lenses are more expensive than mono-focal ones usually used in cataract surgery. The Price of EDOF lenses depends on the lens type, the company that makes them, and the operator’s fees. In India, EDOF lenses cost between Rs. 30,000 and Rs. 60,000 per eye. This is much more than mono-focal lenses, which cost between Rs. 5,000 and Rs. 25,000 per eye. But the price difference may be worth it for people who value better vision.

How good is the Performance of the EDOF lens?

EDOF lenses have a continuous focus range from close to medium to far away. This is different from mono-focal lenses, which only let you see clearly at one set distance. In addition, EDOF glasses use a unique design to change how light rays reach the eye, giving them a more comprehensive depth of focus. This means that people who get EDOF lenses might not need glasses or contact lenses to see better at different distances. EDOF lenses have been shown to improve the quality of life of people with cataracts by making them less reliant on glasses and improving their general vision. But it’s essential to remember that EDOF glasses might not suit everyone. For example, patients who already have macular degeneration or glaucoma may not be able to benefit from EDOF lenses. They should talk to their surgeon to find the best choice for them.

Is EDOF a good IOL lens for cataracts?

Ultimately, EDOF lenses are an excellent new choice for people with cataracts who want better vision and are willing to pay more. EDOF lenses aren’t used very often in India yet, but they are becoming more famous and may become more common in the future. Patients thinking about getting EDOF lenses should talk to an experienced surgeon to find out if they are good candidates and to talk about the benefits and risks.

Can I use the EDOF lens in Night driving?

Can I use the EDOF lens in Night driving? Night driving requires good visual acuity, contrast sensitivity, and depth perception. However, EDOF lenses may not provide the sharpness and clarity of vision needed for night driving, particularly in low-light conditions. In addition, EDOF lenses may produce halos or glare around bright lights, which can be distracting and potentially dangerous while driving at Night. For night driving, it is generally recommended to use lenses with a specific anti-reflective coating to minimize glare and enhance contrast. In addition, some lenses are specifically designed for driving and may provide better visual performance in low-light conditions. 

What are the Advantages & disadvantages of Symfony EDOF IOLs

Extended Depth of Focus (EDOF) in Symfony IOLs are a type of intraocular lens used in cataract surgery. They are made to give good vision from close up to far away, so you don’t have to wear glasses or contact lenses as much. Here are some excellent things about Symfony EDOF IOLs and bad things about them:

Advantages of Symfony EDOF IOLs

  • Extended range of vision: Symfony EDOF IOLs give clear vision from close up to far away, so you might not need to wear glasses or contacts as much.
  • High patient satisfaction: Many people who have gotten Symfony EDOF IOLs are thrilled with how well they see.
  • Good sensitivity to contrast: Symfony EDOF IOLs can give you good sensitivity to contrast, which can be important for things like driving at Night.

Disadvantages Symfony EDOF IOLs

  • Reduced depth of focus: Symfony EDOF IOLs give you a wider field of vision but may not show you the same depth of focus as other types of IOLs. This can make it hard to focus on things at medium distances.
  • Halos and glare may happen: Some patients may see halos and glare around bright lights, especially at Night.
  • Higher cost: Symfony EDOF IOLs are usually more expensive than other types of IOLs, which can be a problem for some patients.
