FAQs on Multifocal Intraocular Lens by Dr Parul Sharma- Max Eyecare

What exactly are multifocal intraocular lenses?

Multifocal Intraocular Lenses are those that have multiple points of focus ─ two or more. These lenses allow a person to focus at different distances, both near and far, simultaneously. Distant as well as near vision can be addressed at the same time, thus diminishing or eliminating the need of spectacles or contact lenses.

What are the different options of multifocal lenses to choose from?

You can make your pick from:

•   Aspheric & Diffractive Multifocal IOL (Such as TECNIS by AMO)
• Diffractive multifocal IOL (Such as ReSTOR by Alcon Laboratories)
• Accomadative IOL (Such asCrystalens  by Bausch & Lomb)
• Refractive multifocal IOL (Such as ReZOOM by Advanced Medical Optics)

How can I be sure whether diffractive/ refractive multifocal IOL is suitable for me?

An eye specialist, after a thorough check-up of your eye(s), will be able to analyse and decide whether you could opt for multifocal lenses or not. The eye surgeon may also take in account your lifestyle, including reading and driving habits, to assert the treatment’s suitability to you.

What are the benefits of diffractive/ refractive multifocal IOL?

Getting multifocal lenses implanted in the eyes during a cataract surgery is a common way of getting rid of glasses. 

Diffractive multifocal lenses will ensure good vision, be it near or far. However, the intermediate vision may vary from person to person. For instance, a person might feel the need to sit closer to the monitor while working on a computer.

The refractive multifocal lens offer outstanding distance and intermediate vision. The near vision may vary and some patients may not be able to read or see anything that is too small.

Are there any disadvantages of diffractive/ refractive multifocal IOL?

There could be a chance that a patient might still require wearing glasses after getting the implants. Around 20% patients who get multifocal lenses might noticeglare and haloes around lights, especially at night. This could lead to discomfort while driving. In majority of cases, patients get accustomed to the changes with time. A person can also usespecial night driving spectacles to control the glare and haloes.

Is there any other option than getting multifocal lenses?

You can go for monofocal lens implantation as a primary alternative to the multifocal ones. Monofocal lenses offer just one point of focus. In that case, you can either get a distant vision lens or near vision lens implanted. You could get these lenses fixed in both the eyes or just one of them as per the need. You could also opt for monovision lenses if you are looking for a near vision implant for one eye and a distant vision one for the other. Other than this, you could talk to the eye surgeon about accommodating lens implants as an alternative to multifocal lenses.

Do I need to wear spectacles after cataract surgery?

If you are getting multifocal lens implants, chances are high that you wouldn’t require glasses anymore. However, the case will not be the same for monofocal lenses because you might need to wear reading glasses even after the surgery. A number of clinical surveys by the Food and Drug Administration (FDA) have proved that around 85% of patients who got multifocal lens implants felt no need to wear glasses post the surgery. Moreover, low corneal astigmatism and overall health of the eyes are also crucial in deciding if you would need spectacles after cataract surgery and implants or no.

Can I get multifocal lens implant in just one eye?

Yes, you can get multifocal lens implanted in one eye only. However, you could draw maximum benefits of multifocality by getting them in both the eyes.

Can anyone go for multifocal lens implants?

No, not everyone is recommended to get multifocal lens implants. The suitability varies from one person to the other. Those who are affected with ailments related to retina, glaucoma affecting central vision, corneal astigmatism, corneal dystrophies, optic neuropathy, or keratoconus are not advised to get these implants. Also, an eye specialist will assess your condition, requirements and lifestyle before deciding whether getting multifocal lens implants would be beneficial for you or not.

How much time will the recovery processafter cataract surgery?

The recovery process post cataract surgery or after getting monofocal or multifocal lens implants is quick. A patient may resume his or her daily activities within a couple of days after the surgery.  However, it may take some time for the brain to adapt to the new optical system, just like how it is when a person starts wearing a new pair glasses. This neural adaption could take a few weeks or a couple of months all together. But the recipient will eventually get the hang of it and will experience better vision.

Phakic Implantable Collamer Lens (ICL)

Phakic Implantable Collamer Lens or ICL refers to the special type of intraocular lens that is used for correction of moderate to severe myopia (near-sightedness). It is also recommendedfor correcting other refractive errors, such as hyperopia and astigmatism.

Phakic intraocular lenses are considered a better alternative to LASIK and PRK eye surgery. In this treatment, the eye’s natural lenses are not removed and new, clear implantable lenses are surgically fixed behind the iris, or in the middle of the cornea and the iris. The treatment eliminates the use of corrective eyewear as phakic lenses allow proper focus of light on the retina, thus providing a clearer vision.

FAQs

Who all are recommended to get this treatment?

Anyone who has myopia (-4 to -20 sphere) with or without Astigmatism (1 to 4 cyl) can undergo this treatment. It is also suggested to those who have been wearing glasses for more than one year and have had a stable number. The eye surgeon would also gauge the anterior chamber depth and endothelial cell density to ensure the requirement and suitability of the treatment.

Who are unsuitableforICL?

A person who is currently affected with eye diseases like glaucoma, iritis, or diabetic retinopathy or have had them in the past are not advised to getICL. Pregnant women should also avoid the treatment as pregnancy may cause fluctuation in the eyes’ vision or power.

Is the procedure for implanting Visian ICL painful?

No, the surgical treatment for implanting Visian ICL is not painful. In fact, the process is very simple and quick.It starts with a detailed check-up of each eye. Measuring corneal and anterior chamber is an important step. The next to follow is thelaser peripheral iridotomy (LPI) procedure. The process includes the use of a laser for creating two tinyincisionsbetween the eye’s front chamber and the lens. It is done a couple of weeks prior to ICL to prepare the eye for the treatment. The step is important since it avoids the build-up of intraocular pressure and ensures smooth passage of fluids.

Is there a specific age to get ICL?

Anyone aged between 21 and 45 years can go for this treatment.

How long does ICL procedure take?

The entire ICL process takes just about 15 to 20 minutes. There is no need for the patient to be hospitalized overnight. However, it still requires some prior arrangements. The patient is given a light topical or local anaesthetic before the treatment. So make sure you are accompanied by someone who can drive you to and from the clinic after the surgery.The eye specialist may also prescribe certain oral medications or medicated eye drops for use. The recovery time is very less. But you will have to visit the surgeon for a follow-up session the very next day of the surgery, to be followed after one month.

Is Visian ICL removable?

Yes, it can be removed. If necessary, an experienced ophthalmologist can remove the implant from the eye.

ICL or Laser Refractive Surgery (LASIK). Which is better?

Dr Parul Sharma of MAX Eyecare says "A number of clinical trials have proved that Visian ICL procedure is much better thanlaser refractive eye surgery. A majority of ICL patients happily reported of more than 99% vision satisfaction".

However, LASIK treatment has certain side-effects. The ICL involves surgical implantation of lens over the eye’s natural lens, which means no part of the eye gets physically changed or reshaped. This cuts down greatly on the risks or side effects like halos and glare. Not to miss, the Visian ICL can be easily removed if there arises any problem or discomfort in the treated eye.

What if I get Visian ICL, but my vision still fluctuates?

One of the benefits of getting Visian ICL is that the treatment is flexible. The surgeon can remove the implant and replace it with a new one in case there is a considerable change in your vision after the treatment. The procedure to replace the lens can be done at any time.

Also, there is no restriction on using contact lenses or wearing glasses post the ICL. Those who have presbyopia can make use of reading glasses even after getting the Visian ICL. For more information,  visit-
