+917738273937Just like we develop grey hair with aging, cataract is also nothing but age related clouding or yellowing of the natural lens in the eye. When we develop a cataract the light doesn’t pass thru well and your vision can deteriorate. You may feel a generalised blur, or notice glare while driving or may need extra light while reading.
When you develop a cataract, surgery is the only treatment available. During cataract surgery the cloudy lens is removed and replaced with a new clear lens. It is the one of the safest and most commonly done procedures around the world.
At Samyak Drishti, we use advanced technology and advanced lenses for our patients and offer excellent outcomes in terms of clarity of vision. More Importantly we offer a choice to be mostly independent from glasses for distance or near depending upon the choice of the lens.
In reality cataract surgery is a safe, effective and predictable procedure which can offer excellent outcomes with low reliance on spectacles
CLEAR VISION, RESTORED
Cataracts cause clouding of the natural lens of your eye. It is one of the leading causes of blurry vision in adults aged 55 and older, and the leading cause of blindness worldwide.
If you are considering Cataract Surgery to correct your vision, don’t you owe it to yourself to carefully consider your choices?
Top Eye Surgeon, Dr. Sujal Shah, founder of Samyak Drishti, has been performing cataract surgeries since he began his specialized surgery practice more than 20 years ago. At Samyak Drishti, we are able to offer you a wide range of state-of-the-art cataract surgery options.
Because of the experience and expertise of our doctors at Samyak Drishti, you can be sure that your treatment plan from either Dr. Sujal or Dr. Manisha will be specifically designed for you, based on your unique eyes and needs.
WHAT ARE CATARACTS?
The natural lens in your eye is normally crystal clear, but with aging, when it becomes opaque, we call it a 'cataract'. A cataract is nothing BUT simply a clouding of your natural lens. NOT a film or growth that occurs in the eye.
IN A NORMAL EYE, LIGHT PASSES THROUGH THE CLEAR LENS AND FOCUSES ON THE RETINA.
A CLOUDED LENS OR CATARACT CAUSES THE LIGHT TO SCATTER ACROSS THE RETINA.
As the cataract progresses, the opacity worsens and prevents light from properly focusing on the retina, the light sensitive tissue lining the back of the eye.
Early lens changes or opacities may not disturb vision significantly. But as the lens continues to change, your vision becomes blurred and you may begin to notice glare, haziness, and difficulty seeing street signs or reading.
WHAT ARE THE SYMPTOMS OF CATARACTS
• For people who have cataracts, seeing through cloudy lenses is a bit like looking through a frosty or fogged-up window. Clouded vision caused by cataracts can make it more difficult to read, drive a car (especially at night) or see the expression on a friend's face.
• Most cataracts develop slowly and don't disturb your eyesight early on. But with time, cataracts will eventually interfere with your vision.• You may experience:
o Blurry or hazy vision, or dim vision that requires brighter lights in order to read small print
o Increased glare and sensitivity to light, especially in bright sunlight or while driving at night
o A yellowing of the vision
o Distortion, double images, or ghosting of the vision
o Increased nearsightedness, requiring frequent changes in your glasses prescription
o Some find it difficult to see the expression on the face of your near and dear ones.
HOW ARE CATARACTS DIAGNOSED AND TREATED?
You'll need to have a thorough examination of your eyes, including dilation and an attempt at a new glasses prescription.
At first, a change in your eyeglass prescription may be all that is needed to temporarily improve your vision. When you feel that your vision affects your daily activities or your lifestyle and you desire better vision, cataract surgery should be considered.
Cataracts can only be removed with surgery. So far, there are no pills, eyedrops or other treatments to prevent or treat cataracts.
WHEN TO DO CATARACT SURGERY? THE DECISION IS YOURS.
There is no single objective test to determine the need for cataract surgery. The final decision to have cataract surgery is always made by the patient, and it depends on how much the decreased vision from the cataract is bothersome.
Dr. Sujal and Dr. Manisha will always explain your status and options to you clearly and let you make your own decision about when to have cataract surgery. If you are considering cataract surgery, here are some factors that you should think about:
• Doing cataract surgery at an earlier stage makes for a quicker recovery and a technically easier surgery.
• Waiting until the vision is very poor can often make the surgery and the recovery more involved.
• Many active patients who still work, drive, and use computers have higher demands for their vision. These patients tend to choose surgery at an earlier stage.
• Due to the fear of surgery, some patients choose to wait until the cataracts become really advanced. This makes the surgery technically more challenging and the recovery slower.
• A few patients choose to have cataract surgery even before they develop vision-blocking cataracts. For these patients, who are typically in their 40s or 50s, refractive lens surgery is performed in order to eliminate or reduce the need for glasses
SURGERY TO RESTORE YOUR VISION
During cataract surgery, the cloudy natural lens of the eye is removed and replaced with an artificial lens implant to restore vision.
Micro Incision Cataract Surgery (MICS)
DR. SUJAL SHAH IS AN EXPERIENCED CATARACT SURGEON
HOW IS THE MICS CATARACT SURGERY PERFORMED
During MICS, a small cut of approximately 2mm is made on the cornea to access the cataract and through this small micro incision your entire cataract surgery is performed in a precise, minimally invasive manner. A large cataract can be broken up into tiny pieces and removed through the micro incision and the procedure continues as the new intraocular lens is placed in the eye to offer you clear vision. This allows a quick and smooth recovery.
ADVANTAGES OF MICS
Small incision – minimally invasive
Gentle
More accurate outcomes
Faster healing
Fewer precautions
Lower risk of infection
Compatible with all advanced iols
UNDERSTAND YOUR VISION - AS SOME CHOICES ARE MADE ONLY ONCE IN A LIFETIME
After cataract surgery, there are many options for replacement lenses depending on your eye, visual needs and lifestyle. Dr Sujal and Manisha Shah will help you choose one that best suits your needs with the goal of providing you the best quality of vision for your needs.
STANDARD LENS IMPLANTS
During your cataract surgery, your natural, cloudy lens is removed and replaced with a new intraocular lens (IOL).
Prior to the development of advanced IOLs, the goal for cataract surgery was to restore vision for simple tasks like watching a favorite tv show. These lenses are commonly known as monofocal lenses, as they have a single focal point and optimise vision for one distance such as looking at distant objects. Monofocal lenses offer excellent vision but, you will require glasses for many of your daily activities like reading, computers, using your mobile phone, most near vision tasks and occasionally driving at night. However, the improvement in clarity was still vastly superior to dealing with the blurred vision caused by cataracts.
Standard monofocal lenses do not correct naturally occurring astigmatism
WITH YOUR NEW IMPLANTED LENS YOU CAN NOW CHOOSE YOUR VISION CORRECTION
There are many options for replacement lenses and Dr Sujal and Manisha Shah will help you choose one that best suits your needs with the goal of providing you the best quality of vision for your needs.
ADVANCED LENS IMPLANTS
Broadly, advanced lens implants can be categorized as toric lenses or presbyopia correcting lenses.
ASTIGMATISM
When the cornea is round distance rays of light come to a single point of focus. When the cornea is somewhat oval shaped, the light rays do not come to a single point of focus and may form multiple foci. This is called astigmatism or cylindrical number.
Most standard lenses do not correct astigmatism and do not provide good vision in patients with high astigmatism and hence requiring a need to wear spectacles after cataract surgery.
Nowadays, astigmatism correction can be done during cataract surgery by using specially designed Toric IOLs that correct larger amounts of cylindrical numbers, allowing patients with astigmatism to see more clearly at a distance.
Toric IOLs do not correct near vision
A STANDARD IOL IMPLANT WILL RESTORE YOUR VISION, BUT IT DOESN’T CORRECT ASTIGMATISM AND YOU WILL STILL NEED GLASSES FOR ALL OF YOUR ACTIVITIES. AT SAMYAK DRISHTI, DR SUJAL SHAH CAN INSERT AN INGENIOUS NEW TORIC IOL TO CORRECT LARGER AMOUNTS OF ASTIGMATISM IN ORDER TO PROVIDE SHARPER VISION. OUR GOAL IS TO RESTORE SHARP VISION WITHOUT THE NEED FOR SPECTACLES OR TO GET AS CLOSE TO THAT AS POSSIBLE.
MULTIFOCAL LENSES SEEING NEAR, INTERMEDIATE AND FAR—WITH A SINGLE LENS
Where our grandparents had the choices of bifocal or trifocal spectacles, today’s multifocal IOLs provide the same vision correction without the maintenance necessary when relying on corrective glasses or contact lenses. Different multifocal IOLs correct vision at all distances; far, near and everything in between. Such IOLs provide a wider range of clear vision and give patients the choice to be independent of spectacles for many or all activities such as reading, computer work, watching TV and driving depending on lens choice, visual needs and lifestyle.
Multifocal IOLs are also called as Presbyopia correcting IOLs. These advanced IOLs are designed with multiple focal zones, so patients can see well close up or at a distance. These lenses are especially popular with patients that are looking for great vision for both distance and reading without the need for glasses or contact-lenses.
TYPES OF MULTIFOCAL LENS IMPLANTS
Multifocal IOLs or Presbyopia correcting IOLs can be bifocal, trifocal or EDOF (Extended depth of focus) lens designs and provide a wide range of vision. You will generally have the ability to see far away and read without glasses. More than 90% of patients with these lens implants rarely need to use glasses. Multifocal lenses are best for motivated patients who have a strong enough desire to be spectacle-free with a mild compromise for distance vision. Learn more about Multifocal lenses.
BIFOCAL IOL
These are the first generation of multifocal lens designs and typically have two principle zones of clear vision. Patient with bifocal IOLs can see well for near and distance. However, objects at an intermediate range such as a computer screen or a laptop may not be clear. Due to the lens design, these patients also have significant haloes at night that affect night driving.
With the development of Trifocal and EDOF lenses, these are becoming less popular with patients.
TRIFOCAL IOL
The multifocal lens is similar to bifocal or trifocal glasses, and can provide a very wide range of vision. You will generally have the ability to see far away and read without glasses. More than 90% of patients with these lens implants rarely need a reason to use glasses. Multifocal lenses are best for motivated patients who have a strong enough desire to be spectacle-free with a mild compromise for distance vision. Learn more about Multifocal lenses.
EXTENDED DEPTH OF FOCUS IOLS
The extended range lens provides a full range of vision following cataract surgery, by helping people focus on far and near objects seamlessly. Unlike Bifocal and Trifocal IOLs, that have two or three principle foci, the extended range lens is a new category of lens that provides a full range of continuous high quality vision, while also minimizing the need for glasses after cataract surgery. It offers crisp distance vision, excellent intermediate vision and allows you to read your cell phone or a menu at arm’s length. You may have some halos around lights at night, although these are generally not bothersome. The extended range lens is best for patients who want excellent, crisp distance vision and the ability to read at arm’s length without glasses. Learn more about Extended Range Lenses.
BENEFITS OF THE EDOF IOL :
• Seamless, day-to-night vision. Patients see clearly at near, intermediate and far away distances, and points in between.
• High-quality vision. Not only does the EDOF IOL get rid of the blurriness caused by presbyopia and cataracts, but it also eliminates discolored and distorted vision.
• Low risk of haloes and glare. A common symptom of cataracts is seeing halos and glare around lights, especially at night. Even after having cataracts removed, some IOLs can also cause this. The EDOF IOL has an extremely low incidence of halos and glare.
However, glasses may be needed when seeing very fine print up close.
Often, a combination of EDOF lens in the dominant eye and a multifocal lens in the non-dominant eye is an excellent choice to overcome the limitation for near vision.
Bifocal, Trifocal and EDOF IOLs are also available with Toric models to correct concurrent astigmatism or cylindrical numbers.
Discuss your vision challenges with our doctors to help you choose the correct IOL for your unique needs. At Samyak Drishti, you can be confident that your vision is in the hands of caring, skilled and experienced doctors. You can rest assured that you will receive one of the best choices of multifocal lens implants suitable for your eyes.
WHAT TO EXPECT AFTER CATARACT SURGERY
CATARACT SURGERY IS AMONG THE MOST FREQUENTLY DONE SURGERIES IN INDIA WITH OVER 3 MILLION PROCEDURES DONE EACH YEAR. RECOVERING FROM CATARACT SURGERY IS VERY STRAIGHTFORWARD FOR THE VAST MAJORITY OF PATIENTS.THE PROCEDURE IS DONE ON AN OUTPATIENT BASIS AND USUALLY TAKES ABOUT 10 TO 15 MINUTES. YOU WILL HAVE A PROTECTIVE EYE SHIELD PLACED ON YOUR EYE WHICH CAN BE REMOVED FOR SHOWERING AND WHEN WATCHING TV OR READING. IT SHOULD BE REPLACED WHEN NAPPING OR SLEEPING TO PROTECT THE EYE AS INSTRUCTED. AFTER YOU RETURN HOME, IT IS BEST TO RELAX FOR THE REST OF THE DAY. WITH THE CATARACT GONE, YOU WILL NOTICE THE WORLD A MUCH BRIGHTER PLACE AS THE CLOUDY LENS HAS BEEN REPLACED WITH A CRYSTAL CLEAR LENS. YOU MAY FIND IT MORE COMFORTABLE TO WEAR THE SUNGLASSES WHEREVER THERE IS BRIGHT LIGHT BUT IT ISN’T MEDICALLY NECESSARY.
BLURRY VISION IS NORMAL AFTER CATARACT SURGERY
YOUR TREATED EYE MAY REMAIN DILATED FOR UP TO 24 HOURS AND YOU MAY ALSO NOTICE YOUR VISION IS BLURRY FOR SEVERAL DAYS OR MORE. IT IS NORMAL TO HAVE SOME FLUCTUATION OF VISION AS YOUR EYE ADAPTS TO THE NEW LENS. FOLLOWING SURGERY IT IS NORMAL TO EXPERIENCE IRRITATION, DRYNESS, SCRATCHINESS OR WATERING FOR A FEW WEEKS. YOU WILL BE GIVEN ANTIBIOTIC, ANTI INFLAMMATORY AND LUBRICATING EYE DROPS TO USE WHICH WILL HELP WITH IRRITATION. FOLLOW THE INSTRUCTIONS CAREFULLY FOR THE USAGE AND GRADUAL TAPERING OF THE EYE DROPS FOR BEST RESULTS.
DR.SUJAL SHAH OR DR.MANISHA SHAH WILL SEE YOU WITHIN A FEW DAYS OF SURGERY TO ENSURE THAT HEALING IS PROGRESSING AS EXPECTED. IT WILL TAKE ABOUT A MONTH FOR THE EYE TO BE FULLY HEALED BUT YOU WILL BE ABLE TO RESUME MOST ACTIVITIES IN JUST A FEW DAYS.
CATARACT SURGERY COMPLICATIONS
CATARACT SURGERY IS VERY SAFE AND UNCOMPLICATED IN THE MAJORITY OF PATIENTS. HOWEVER IF YOU NOTICE ANY OF THE FOLLOWING SYMPTOMS, CONTACT US IMMEDIATELY:
• MODERATE EYE OR EYEBROW PAIN
• DRAMATIC DECREASE IN VISION
• INCREASE IN REDNESS AND DISCHARGE
RETINAL DETACHMENT
THOUGH VERY RARE, RETINAL DETACHMENT CAN OCCUR FOLLOWING SURGERY. SIGNS THAT YOU MAY EXPERIENCE DURING RETINAL DETACHMENT ARE GIVEN HERE. PLEASE CONTACT US IMMEDIATELY IF YOU ARE EXPERIENCING ANY OF THEM.
A CURTAIN COMING ACROSS YOUR VISION OR A FLASHING LIGHT AT THE CORNER OF YOUR EYE OR FLOATERS.
FLOATERS
You may also notice a large number of new floaters (tiny specks or “cobwebs” that drift in your vision) occurring 2 weeks or more after surgery. These may appear like a swarm of bees or a spider web. Please note that this is different from the few floaters you will likely notice after your procedure. These are normal and to be expected.
GENERAL CATARACT AFTER CARE ADVICE
The following are tried and tested instructions that will assist your recovery and ensure you have the best possible outcome from your surgery. If you have any questions at all about what you can or cannot do after your procedure, please call the clinic for clarification.
You can resume your regular diet and medication schedule immediately following surgery.
Please avoid touching, rubbing or washing the eyes for one week
you can bathe or shower below the neck.
To guard against infection, do not swim, go in a hot tub or jacuzzi, have a steam bath, or go into a dry sauna for one week after your surgery.
Eye makeup should not be worn for 2 weeks, to guard against infection. Eye makeup and eye liner accumulates germs and could cause an infection.
Keeping your diabetes and blood pressure under control even helps the eye heal
Do not exercise for at least 48 hours. After this period you may resume any light exercise that does not involve lifting heavy objects. Check with one of our doctors if you are uncertain when to begin a certain type of exercise or activity.
Most patients go smoothly through recovery with no issues at all other than minor eye irritation and having to adjust to the new clear lens.
If you run into anything that is concerning to you please don’t hesitate to call. We can be reached at 23613937 / 23623937.
FREQUENTLY ASKED CATARACT
Modern cataract surgery is one of the safest and most effective procedures in medicine. In this procedure the cloudy lens is broken into smaller fragments and sucked out thru a small microincision, in the cornea. We then implant an artificial lens to improve your quality of vision.
The standard lenses are implants that are designed to give you good vision for a fixed distance without the need to wear glasses. With these lenses patients see pretty well for distance but you will need glasses for near, like reading newspapers, mobile and laptops. They work well for people who don’t mind wearing glasses for a large part of their lives
Once you arrive for your cataract surgery, you will be greeted by our staff, who will start the process by checking all your papers, investigations, and how well your pupils are dilated, or if you need to instill any more of the dilating drops.
They will then escort you to the cataract surgical suite. Here the anaesthesiologist will recheck all your investigations and examine you for fitness for the planned surgery.
The staff will then prepare you for the cataract surgery and take you into the cataract surgical theatre where Dr Sujal Shah will perform the surgery. You will feel no pain, occasionally you may feel a little pressure while your cataract is being emulsified and bright lights around the eye once the cataract is removed. Dr Sujal will continue talking to you and if you wish you can talk to him.
The entire surgical process will typically take 15-20 minutes. After surgery you will be taken to the recovery area. Here the assistant will explain post-operative precautions and medications.
We will see you the next day for the post-operative check up. Typically, the vision is quite good by the next day, but it may take upto a week for the fluctuation in the vision to settle.
After cataract surgery it takes a few weeks for the vision to stabilize, so we generally don’t prescribe your final prescription for regular glasses or reading glasses until a few weeks are passed. But in the interim if you wish you definitely can use reading glasses
There are lots of people who don’t wish to wear glasses after cataract surgery, and for such patients we have Advanced Lens Implants. Clear vision for many activities, both up close and far away, can be achieved with these lenses.
1. There are several varieties of advanced lenses.
.
2. Toric lenses that are designed to correct astigmatism
3. Bifocal or multifocal reduce one’s dependence on glasses for near and far.
4. Trifocal lenses reduce dependence for distance, intermediate and near vision.
5. Extended depth lenses reduce dependence for distance, intermediate and near vision
Multifocal or Bifocal lenses are a variety of advanced lenses that give good vision for far away and near vision.
Most of the patients with these lenses never wear glasses after their cataract surgery. However, the crispness of distance vision is not as good as monofocal lenses and they do not correct for intermediate vision. Many patients may also experience halos or glare around lights during night time.
With changing lifestyles and increasingly demanding visual needs, Trifocal lenses were developed to improve quality of vision over multifocal lenses. With a trifocal lens, patients get good functional vision at distance, intermediate and near. Also, night time glare and halos are significantly less as compared to multifocal lenses
EDOF lenses are a further evolution of multifocal and trifocal lenses. Multifocal are designed with 2 principal foci to give optimum clarity for far and near. Trifocal lenses are designed with 3 principle foci to give optimum clarity for far, intermediate and near. But, in both multifocal and trifocal lenses, vision in the intervening ranges may be unclear. An EDOF IOL gives a more continuous range of focus from far to near, with almost no halos or glare at night. Typically, glasses are not needed for driving, watching TV, working on a computer or using your mobile phone. However, near vision is not as clear as with a multifocal or a trifocal lens and glasses may be needed for fine printed matter. Often, a combination of EDOF lens in the dominant eye and a multifocal lens in the non-dominant eye is an excellent choice to overcome the limitation for near vision.
Multifocal, Trifocal and EDOF lenses are together called Presbyopia correcting lenses. These lenses offer a large range of excellent vision without the need for glasses for most of their activity like driving, reading or working at the desk. Patients with these lenses can do pretty much everything during the day, but they may experience some discomfort in the quality of vision at night while driving or with oncoming headlights. They typically experience splaying out of light, most of them get used to it after a few months All in all most patients are very happy with the independence of being able to do everything without glasses and this supersedes the mild issues that may be experienced during night. These are best suited for people who are motivated to be spectacle free most of the time for distance and near and are willing to accept some trade off in the quality of vision at night.
Traditionally most people opt for what is called a standard lens implants that gives very good vision, but, if you have naturally occurring astigmatism, you may experience distortion of vision and will need glasses to see well.
Over the last 10 odd years we now have advanced Toric lenses that give the opportunity for superior distance quality of vision than monofocal lenses in patients with naturally occurring astigmatism. Now, Multifocal, Trifocal and EDOF lenses are available in toric versions to correct astigmatism while also allowing clear intermediate and near vision.
The choice of a lens is an important one, as this is a lifetime decision and the effects of your choice will be permanent. Before you decide, you should explain your vision needs to Dr Sujal Shah or Dr Manisha Shah. After they understand your needs and review the findings of your examination and eye scans, they can discuss your choices with you to help you decide the most appropriate choice for your eyes. Generally speaking, If you do not mind using glasses after cataract surgery, you could do very well with a monofocal IOL. If you have naturally occurring astigmatism and wish to optimize your distance vision, but, don’t mind wearing glasses for intermediate and near work, you could be a good candidate for a Toric IOL For those who do not drive much at night, but would prefer to read print without glasses, we recommend a trifocal lens For people who actively use a mobile phone and computer for professional and vocational needs, travel a lot, drive at night and typically don't read much print matter, we recommend EDOF lenses. The combination of a EDOF lens in the dominant eye and a Multifocal (Bifocal) lens in the non-dominant eye is a great choice for those who require a more seamless vision, but also want to be able to read without glasses.
Advanced lenses like the EDOF, Trifocal or Toric lenses are designed to give you a wide range of vision and are a good option if you want to see clearly without glasses. That’s the reason we do them and recommend them to our patients. While advanced lenses significantly reduce the dependence on glasses, there can be some variability and some patients may see differently because the results cannot be guaranteed. If we do an advanced lens and if your vision isn’t quite as expected, we can usually do an adjustment. It can be a LASIK or something else in order to sharpen your vision. At times, however, a thin pair of glasses may be needed for clear vision.
