By far the most important organs of sense are our eyes. We perceive up to 80 per cent of all impressions by sight and it's the eyes that best protect us from danger even in the absence of our other senses.

Aurovue DFine is the best IOL and has helped many a patient regain their vision. We have put together a comprehensive list of questions that can help patients gain a better understanding of cataracts and how IOLs work.

We also recommend that you seek your doctor's guidance in seeking a suitable solution, designed specifically for you.

Generally Asked Questions

What are the common causes for cloudy vision?
Cloudy Vision is where objects are obscured and appear "milky" is often mistaken for blurry vision. Cloudy vision usually is a symptom of specific conditions such as cataracts, but blurry and cloudy vision can both be symptoms of a serious eye problem.
What is Presbyopia?
Presbyopia is the loss of near focusing ability of the eyes that occurs with age. When you become presbyopic, you need to hold your phone or the newspaper farther from your eyes in order to be able to focus on the material and see or read clearly. Glasses are the most common solution for presbyopia - typically multifocal lenses that can correct vision at all distances.
What is Cataract?
Cataract is the clouding of the eye’s natural lens that causes a loss of vision, typically in people over 40 years of age. Typically cataracts start small and vision becomes blurred. Symptoms may include faded colors, blurry vision, halos around light, trouble with bright lights, and trouble seeing at night.[1] This may result in trouble driving, reading, or recognizing faces. As cataracts progress, vision becomes increasing blurred and eventually leads to a complete loss of vision if left uncorrected.
What causes cataracts?
The eye is made up primarily of water and protein arranged in a precise manner to keep the lens in the eye clear and let light pass through it. It acts like a camera lens within the eye. Aging is the primary cause of Cataracts. The protein in the eye clumps together making the lens blurred and therefore causing an impairment in vision. While the cause of this change in the eye lens in unclear, a number of contributing factors like UV radiation from sunlight or other sources, diabetes, hypertension, obesity, smoking and even the prolonged use of certain kinds of medication can cause cataracts.
Can Cataracts be prevented or cured?
No. Most studies show that cataracts cannot be prevented or cured. At this time, surgery is the most viable option to treat cataracts. While dietary and lifestyle changes may help delay cataracts, they cannot reverse cataracts that are present.
What happens if cataracts are left untreated?
In most cases, over time, cataracts tend to worse and cause continual reduction in vision. If left untreated, it can cause blindness. Untreated cataracts can become “hyper mature” - a condition that makes cataract surgery more difficult and can cause other complications.
How is a Cataract surgery done?
There are different types of cataract surgery and the technique used by the doctor or surgeon depends on a number of factors. In most cases, the doctor or surgeon makes a small incision in the eye to gain access to the cataract lens which is then broken up with ultrasound energy and removed from the eye before an IOL is put in its place with a special instrument. The IOL is then secured in place of the natural lens. Typically no stitches are required for this kind of a procedure. Laser - assisted cataract surgery replaces a number of the steps performed by hand-held instruments with a computer controlled laser for added precision. The entire surgery process normally takes about an hour and you should be able to return home the same day. Consult your doctor on the type of procedure best suited for your needs.
What is an IOL?
An Intraocular Lens or an IOL is a lens used to replace the natural lens in your eye by implanting it in place of your natural lens that has deteriorated due to a cataract or myopia. It is made from a hydrophobic material with plastic side struts called haptics which help hold the lens in place within the eye. There are different kinds of IOLs available. Consult your doctor to which IOL would be the best option for you and your needs.
Are lens always replaced in a Cataract surgery?
As cataracts are caused due to the clouding of the eye’s natural lens, the doctor or surgeon will remove the clouded lens and replace it with a clear, plastic intraocular lens (IOL).
How long does a Cataract surgery take?
Cataract surgery is simple and relatively painless with very good results (20/20 to 20/40 post surgery). Consult your doctor on how long this procedure will take for you based on your symptoms.
What is the difference between a multifocal and a monofocal IOL?
There are two main types of intraocular lenses: monofocal and multifocal. The difference between monofocal and multifocal lens implants is actually similar to the difference between monofocal and bifocal glasses. Monofocal IOLs are focused at a precise point, and may often require reading glasses in order to optimize near vision without glasses. Multifocal IOLs on the other hand have two (bifocal) or three (trifocal) focal points simultaneously to provide a wide range of vision(near to far) better range of vision and eliminate the need for glasses or contact lenses.
Is a Multifocal IOL same as natural lens?
No, As a person ages, the natural lens becomes more rigid and functions more like a monofocal lens. Even though lens implants or IOLs do not change shape, a multifocal lens can compensate for the eye’s inability to change shape by allowing the eye to see at distance and near simultaneously through the same optic.
How do you choose the right lens?
There are a range of benefits associated with Aurovue Dfine IOL. Consult your doctor or surgeon to evaluate your case history and your options before settling on specific Aurolab IOL. Your decision will be based on many factors including your health and your lifestyle. For example, do you spend a lot of time reading, or do you prefer outdoor activities? Do you have a range of hobbies? Do you engage in a lot of night-time activities, especially driving? Visit your doctor for a recommendation following a complete eye exam and some speciality scans to determine if the Aurovue DFine IOL is the right choice for you.
What is the alternative to a Multifocal Lens implant?
The primary alternative to multifocal lens implantation is monofocal lens implantation. While a monofocal lens may give the patient good distance vision, corrective measures like reading glasses will be required for near vision activities like reading.
Is a multifocal IOL suitable for all patients?
No, While a multifocal IOL may be suitable for most patients, patients with retinal problems, advanced glaucoma, irregular corneal astigmatism, corneal scarring, keratoconus, corneal dystrophies or optic neuropathy are not ideal candidates for a multifocal IOL. Certain professionals like drivers who mostly work nights, watch makers, professional photographers, goldsmith, and miners are also not ideal candidates for a multifocal IOL.
Reach out to your doctor who can go over the advantages and disadvantages of a multifocal lens as applicable to your individual lifestyle and expectations.
Are glasses or contact lenses required to correct vision after an IOL replacement?
In most cases, depending on the type of IOL used, glasses may be required for reading (near sight) and this would depend on your visual needs. Multifocal IOLs like DFine however can provide excellent outcomes that may enable many people to be free of glasses for most of their day. Post-surgical sensitivity to light can be corrected with photochromic glasses that darken when used in the sun. Minor blurriness normally do not warrant additional surgery.
Speak to your doctor on what results you can expect after a DFine IOL cataract surgery and ensure regular follow ups to obtain the best results for your needs.
What is the recovery time for this procedure?
Recovery from cataract surgery is the same, irrespective of the type of IOL (monofocal lens or a multifocal lens) used in the procedure. The pre-surgical steps and appointments as well as the post-surgery recovery and precautions recommended by the doctor. The brain however will take some time to adjust to the new optical system created through the implant of the IOL. This neural adaptation varies from patient to patient and can anywhere take from a few weeks to months to occur. Over time, patients typically notice that they become less aware of their vision as this neural adaptation takes place and their vision improves.
Will there be any restrictions imposed on a patient who has undergone the implanting of the Aurovue DFine IOL?
No – The patient can resume to your daily activities as per their doctor’s recommendation.
Can I expect to retain my 6/6 vision throughout my life after the Aurovue DFine IOL implant?
Yes – in most cases, patients retain good vision after the implant of the Aurovue DFine IOL. However in certain cases the development of any pathology in the eye could lead to the patient experiencing a mild drop in vision. This is primarily due to the development of a layer behind the IOL (PCO) that occurs after a typical cataract surgery irrespective of IOL type. This can however be treated with a minor corrective procedure by your eye doctor.
What are the side effects, if any, after a multifocal IOL implant?
Implantation of a multifocal lens is associated with all the risks and side effects of cataract surgery. Some patients may experience a mild glare and halos that are visible in the dark as a side effect of the multifocal lens implant. However the brain will adapt to these side effects over time.
Why choose Aurovue Dfine?
Aurovue Dfine multifocal IOL use superior hydrophobic material and is designed to help cataract patients enjoy a wider range of vision, from near to intermediate to far. Aurovue Dfine offers sharper vision at all distances, even under low-light conditions. This means, you can read a product label, work on your laptop or mobile, play cricket, or even drive at night, minimize the need of spectacles. Aurovue Dfine has been developed using Truedge technology to prevent the chances of posterior capsular opacification, a post-operative complication arising from cataract surgery.
Will the patient have 6/6 vision after the Aurovue DFine IOL implant surgery?
In most cases, patients have near – perfect vision after the Aurovue DFine IOL implant, without glasses or contact lenses if their only ailment before the implant was a cataract. Is the Aurovue DFine IOL very expensive? No – the Aurivue DFine IOL is a once-in- a-lifetime investment and is a cost effective option as compared to the investment a patient normally makes on spectacles even with periodic monofocal implants.
Should I implant the same IOL both my eyes?
For a patient with a cataract in only one eye and if vision in the other eye is unimpaired, a multifocal IOL would be a better choice for the affected eye as compared to a monofocal IOL as it provides a better range of vision without any corrective measures like glasses. However, if a patient has cataracts in both eyes, multifocal IOLs are recommended for both eyes to realise the full benefit of multifocal. IOLs and clear vision. However if one of the eyes already has a monofocal IOL implant, a multifocal IOL in the other eye may not help the patient realize the full benefit of the multifocal lens implant.
How does Cataract affect vision?
Cataract causes blurred vision in the initial stages. Depending on the type of cataract and the severity, cataracts may also seem to make bright objects too bright, cause more glare (during night time), dullness in colours and eventually can lead to loss of vision.
