Cataract is the leading cause of decreased vision and blindness in our country. It can be cured by a simple cataract extraction microsurgery, which, these days is performed using advanced technology in a short time.
We use the latest phaco-emulsification machine for Micro-Incision Cataract Surgery (MICS) This involves the removal of the cataract through a 2.2mm incision with the implantation of foldable Intraocular Lenses (IOLs). Patients are offered the latest in IOL technology personalised to their eye and needs. These include Aspheric Monofocal or Multifocal lenses. Toric IOLsare specialized IOLs used in patients with associated corneal astigmatism, i.e. High cylindrical powers. To minimize calculation errors in the implanted IOLs ,we now routinely do corneal topography, Immersion/Ultrasound or Optical Biometry and Aberrometric Evaluation in all patients undergoing cataract evaluation.
What is cataract?
Cataract is a clouding of the natural lens of the eye. When we focus on an object, light rays travel into our eye through the pupil and are focused through the lens onto the retina, a layer of light-sensitive cells at the back of the eye. The lens must be clear in order to focus light properly onto the retina. If the lens has become cloudy, this is called a cataract.
What are the causes of cataract?
Ageing is the most common cause of cataract. With increasing age, the normal clear crystalline lenses slowly loses its capacity to remain clear. Other causes include diabetes, injury, usage of certain medications, and secondary to other eye diseases such as uveitis and glaucoma. Cataracts can occur early in diabetes, myopia (short sight) and as a hereditary predisposition.
What symptoms will I have if I am developing cataract?
Most age-related cataracts develop gradually. As a result, you may not notice subtle changes in your vision right away when cataracts first develop. Gradually, as cataracts progress, you may have symptoms such as:
- Painless cloudy, blurry or dim vision
- More difficulty seeing at night or in low light
- Sensitivity to light and glare
- Seeing halos around lights
- Faded or yellowed colors
- The need for brighter light for reading and other activities
- Frequent changes in eyeglass or contact lens prescription
- Double vision within one eye
When to go for Cataract removal ?
Cataract should be removed as soon as it begins to affect daily activities.When any of the above mentioned symptoms set in, it is the right time to go for Cataract removal. It is not advisable for one to wait till the cataract ripens into a matured cataract. Cataract surgery can be undertaken successfully in any season. Summer or rainy season have absolutely no effect on the outcome of the cataract surgery.
What is the intraocular lens suitable for my eyes?
At Neo Vision Eye Care, we believe that your eyes are unique and require a customised lens selection. There are a wide range of intraocular lenses available in market. Typically, monofocal lenses correct vision for distance and multifocal lenses correct vision for distance, intermediate and near vision. If your eyes have co-existing cylindrical number i.e. astigmatism, toric intraocular lenses are available for correcting that.
To know more about these lenses, you can discuss the pros and cons with Dr Mukesh Paryani.
What happens on the day of surgery?
Surgery is a “walk in- walk out” procedure. Pre-operatively dilating drops are instilled which take around 1 hour to act .Surgery is mostly done under topical anaesthesia i.e. only numbing eye drops. Anaesthetic drops numb the surface of the eye and the surgery can be comfortably and painlessly. The eye remains open after surgery and you may be given protective goggles to wear. Some patients may require an anaesthetic injection before the surgery. A routine surgery lasts approximately 10 minutes with the preparation time being of similar duration. One could expect to spend half a day at the hospital on the day of surgery.
Is there much discomfort after surgery?
Cataract surgery is pretty much painless and so is the post-operative period. There is mild irritation (or foreign body) sensation for a few days. There may be mild redness & watering of the eyes which will subside in a few days.
What do I do after surgery?
There is no need for bed rest after surgery. One can walk, eat normally, watch TV and be normal around home on the day of the surgery. One needs some protective glasses only when outdoors.
When can I resume my normal work?
One can resume work even on the day after surgery.
One could either work from home or office, but should remember to instill the drops as advised.
Normally, the spectacle number after surgery is prescribed only after 4 weeks, until when reading may be an issue for those with Monofocal Intraocular Lens implants. This is not the case after implantation of a multifocal IOL.
What about post-operative restrictions?
One should avoid water from directly getting into the eyes for 10 days after surgery.
Youcould sponge the hair and face properly even on the day after surgery.
Normal bathing (taking precautions for the eye) can be resumed the day after surgery.
After a week to 10 days one can be completely normal.
Bending down, chewing hard foods or lifting moderate weights are not at all a problem after surgery.
One can be pretty much be normal after surgery
When will I see well?
The vision will be bright and pretty much clear the day after surgery.
Full vision will be restored gradually in a few days time.
How do I clean my eye after surgery?
One would not normally need to specifically clean the eye after surgery.
Cotton balls or a cotton cloth should be dipped into container containing water .The water along with cotton is allowed to boil and then allowed to cool down till it is lukewarm. The cotton is then taken from container using washed hands and then used to clean closed eyes and rest of the face
Can I travel after surgery?
There is no problem in travelling on the day after the surgery provided one remembers to instill the eye drops. Timings will be given for the instillation of the eye drops, but an hour this way or that does not cause any problem.
Cataract is the leading cause of treatable blindness worldwide. It has profound impact on patient’s quality of life. At Neo Vision Eye Care, we help and educate people about cataract and cataract surgery options.A cataract is a clouding of the eye’s lens and is a major cause of preventable blindness in INDIA. Cataract can occur at any age due to a variety of causes. Patients with cataract experience diminution of vision, glare, night blindness, halos and Starbursts around lights, colours appearing duller, dimmer, or browner.
Modern cataract surgery is very different from the procedures performed 10 years ago. Cataract surgery used to require a hospital stay and a lengthy recovery period. But today, cataract surgery is a day care procedure and generally takes less than 15 minutes with no-stitch, no eye-pad, no injection and the patient is back to many normal activities by the next day. Post-operative vision has dramatically improved over the years with monofocal intraocular lenses (IOLs) correcting vision for distance and new high-tech IOLs such as multifocal IOLs reducing dependency on glasses for near and intermediate distance also.
With state of the art Micro-incision Cataract surgery system and using the latest in phacoemulsification technology performed by experienced surgeons, one can achieve wonderful and predictable outcomes in Cataract Surgery Today.
Keratoconus : Collagen Crosslinking (C3R,CXR,CCL,KXL)
New treatment options offers a new hope in patients of progressive Keratoconus
Keratoconus is a bilateral ocular disorder in which the cornea assumes a conical shape due to thinning of the stromal collagen tissue. It is a relatively frequent disease with an incidence of 1 in 2000 in the general population. It classically has its onset at puberty and is progressive until the third or fourth decade of life when it usually arrests.
Keratoconus can be detected clinically by slit lamp examination by an Ophthalmologist and the diagnosis can be confirmed by corneal topography.
Currently, the mainstay of treatment for Keratoconus includes glasses and / or specially designed rigid gas permeable contact lenses which offer good quality of vision.
In advance cases, visual improvement in keratoconus can be achieved surgically by placement of intracorneal rings, topography guided ablation treatments and corneal grafting.
Collagen Cross Linking is a new modality of treatment that aims to arrest progression of keratoconus.
What is Collagen crosslinking ?
The corneal collagen is crosslinked with the help of ultraviolet rays ( UVA ) and a photosensitiser, Riboflavin , thus enhancing the rigidity of corneal tissue and stabilizing the condition
Who is a suitable candidate for Collagen crosslinking ?
Patient must be a proven case of keratoconus with documented progression of the disease.
Patient’s corneal thickness must be at least 400 microns.
Patient should not be pregnant or nursing.
How is Collagen crosslinking performed ?
The treatment is performed under topical anaesthesia with the patient in a lying down posture in the sterile environment of the operating room. The patient’s corneal epithelium is gently removed, following which Riboflavin solution is applied every 5 minutes for the first half an hour. Thereafter the patient’s cornea is exposed to UVA light for half an hour. The treatment is painless and lasts for an hour, at the end of which the eye is patched
What is accelerated crosslinking?
Accelerated Crosslinking involves use of latest equipment in crosslinking which delivers same energy in shorter period of time making the total procedure to be over in less than half an hour .This treatment offers less patient discomfort and early recovery.
When can the patient resume normal routine ?
After the treatment, patient will be able to resume work within 3 to 4 days.Care should be taken to avoid entry of water into the eyes during this period.The use of contact lenses may be resumed 6 weeks after treatment.
How often must the patient come for follow up ?
The surgeon will examine the patient’s eye daily for the first 2 to 3 days until the epithelial healing is complete. Eye drops will be used for 4 months. Patient will have to come for follow up at 6 weeks, 3 months, 6 months, 1 year and 2 years after the procedure.
Can both eyes be treated at the same time?
If both eyes are suitable for Collagen crosslinking, the treatment is performed on one eye at a time .The timing of treatment of the second eye is best decided in consultation with your ophthalmologist.
What are the possible side effects of the procedure?
A foreign body sensation, irritation or watering accompanied by pain is not uncommon on the day of treatment. Analgesics for relief from pain will be prescribed , and the pain usually subsides within 24 hours. Dryness of the eyes frequently follows this treatment and may last for 6 to 8 months. Tear lubricants are therefore recommended for the period.
Were you rejected for LASIK surgery owing to your high glass power? Around 10-15% of patients who want to get rid of their glasses are unable to undergo laser vision correction owing to their very high glass power or thin corneas (outer glass-like covering of the eye). Well, we provide a wide range of options for patients whom LASIK surgery is not possible.
Today there is option of implanting Phakic intraocular lenses (ICL) in these patients. The ICLs can correct upto -24D of myopia, +10D of hyperopia and upto 6D of astigmatism(cylinder). These lenses are ultra-thin lenses which work exactly like your contact lenses; the difference being ICL is permanently implanted into your eye and don’t require any messy daily maintenance as contact lenses do. The procedure is a day care procedure and completely painless. It is a no injection, no eye-pad, and no stitch procedure. It has less glare issues on patients with large pupils. It is very stable and no regression is noted over time.
A safe and predictable visual outcome with ICL makes it an excellent and viable option for those who cannot undergo laser vision correction with LASIK.
Did you know that India stands as the capital of diabetes in the world? According to W.H.O. the number of diabetics in our country is also expected to double in the by 2025. People with untreated diabetes are said to be 25 times more at risk for blindness than the general population. Diabetes can affect sight by causing cataracts, glaucoma, and most importantly, damage to blood vessels inside the eye, a condition known as “diabetic retinopathy”
At Neo Vision Eye Care, we provide the diabetic individuals with the right treatment to avoid total loss of vision. The longer someone has diabetes, the more likely he or she will get diabetic retinopathy. If patient also have hypertension, raised cholesterol, kidney problems then the risk goes even higher. In most cases the lack of awareness is the main reason for blindness due to diabetic retinopathy.
Creating awareness, regular eye check up and treatment, when needed can prevent most sight loss from diabetic retinopathy. To prevent progression of diabetic retinopathy, people with diabetes should control their levels of blood sugar, blood pressure, and blood cholesterol.
In advanced sight-threatening diabetic problems can be treated by laser treatment and is carried out in just 10 minutes and the patient does not have to stay in the hospital. Depending upon the severity, some patients need two to three laser sessions.
In some cases, injections need to be given to reduce severity and surgery is usually restricted to very severe cases where laser therapy and intravitreal injections have limited role.
We recommend every diabetic to undergo regular eye checkup and advice patients to strictly keep blood sugars under control .
From radial keratotomy (1978) and photorefractive keratectomy (1980s), refractive surgery has come a long way to highly sophisticated technology taking care of your eyes and correcting your refractive error.
The journey of refractive surgery started with blades and incision, now converted into more precise LASER technology. A customised LASIK surgery does laser correction considering shape of your cornea i.e customised to your eyes and thus gives a better visual outcome than a regular non-customised LASIK surgery which can cause minimal glare problems after LASIK surgery.
Today apart from excimer laser, the introduction of femtosecond laser technology has not only revolutionized refractive surgery but also has made LASIK surgery bladeless .Bladeless customised LASIK surgery is most preferred and safest way to go for your LASIK surgery. In this procedure, a computer controlled Femto-second laser is used instead of microfine blade as a part of the LASIK surgery; making the entire procedure more safe and predictable with finest visual outcomes. The LASIK surgery is a day care procedure taking less than 15 minutes .the patient can be discharged the same day and can resume day-to-day activities from the next day itself.
A LASIK surgery such performed gives superior visual quality with high precision and associated with minimal side effects. Thus improving your overall quality of life and giving you a spectacle free vision to see this beautiful world.
If any patient is found not fit for LASIK surgery owing to high glass power or lesser corneal thickness, they can be considered for phakic implantable lenses. Phakic implantable lenses are ultrathin lenses that work exactly like your contact lens, difference being that it is implanted inside the eye permanently and one doesn’t need to take out or change it frequently. The outcome is highly predictable and is reversible .
Phakic intraocular have a long way not only treating distant vision but with the introduction of presbyopic phakic intraocular lenses , they can treat patients who have reading glasses also , thus reducing their dependency on reading glasses.
Thus the armamentarium today has everything that can take care of all ranges of refractive error for all ages .
Refractive Surgery includes any surgery that is done to reduce one’s dependency on glasses. LASIK surgery is the most common vision correction procedure all over the world.
LASIK –Laser In Situ Keratomilieusis surgery basically involves two steps- Creating a precise thickness flap on the cornea ( glass like covering of eye) and then using excimer laser to alter its shape to give clear vision without glasses. In bladeless LASIK, instead of a motorized blade, another laser called as Femtosecond Laser is used to create flap, thereby increasing safety, efficacy and predictability of the LASIK surgery.
With its excellent safety profile, patient comfort and superior visual outcomes, Blade-free LASIK is among the fastest-growing refractive surgical techniques in the country today .The procedure is a simple, painless and comfortable solution that allows the patient to adapt to a life free from glasses. The wavefront optimized platform gives best image quality with a clearer vision. The entire vision correction procedure takes less than 15 minutes in time and patients are able to resume their day to day activities right from next day
At NEO VISION EYE CARE, along with providing the best in eye care, we believe educating our patients and keeping them up-to- date with modern technology that plays a key role in making your experience of surgery a painless and memorable one.Here are some of frequently asked questions for getting rid of your glasses
Here are some of frequently asked questions for getting rid of your glasses
- What is LASIK surgery
In simple terms, LASIK surgery involves reshaping of your cornea (the front glass like covering of eye) using highly precise laser called EXCIMER LASER
- What is bladeless LASIK SURGERY?
With the introduction of Femtosecond LASER it is now possible to perform LASIK treatment entirely without using a mechanical device which requires a microfine blade (microkeratome); In other words laser replaces the blade giving it an extra edge in safety and precision
- Am I fit for LASIK SURGERY?
Your Eye surgeon would first perform a clinical assessment of your eyes and would recommend a test called as Topography which would enable them to decide whether you are fit for LASIK surgery or not.
Around 10% of patients are labelled unfit for LASIK surgery. That is why it is mandatory to undergo a proper pre-LASIK checkup with your LASIK surgeon
- Can I get permanent spectacle independence even if I am not fit for LASIK surgery?
Yes . There are special lenses that can be implanted inside your eyes safely and permanently to give you spectacle independence. These are permanent lenses which stay inside your eye and are called Implantable Collamer Lens (ICL)
- What is the recovery time after LASIK surgery
Ans. LASIK surgery itself is a painless surgery which gets over in less than 5 minutes. The patient can get back to routine activities right from next day of surgery.
POST LASIK INSTRUCTIONS
What you are likely to experience after the procedure:
- Mild or moderate watering from both eyes is common and can differ from one eye to the other on the day of treatment.
- Foreign body sensation or irritation in the eyes.

- You can watch TV, read books, from the day after your treatment.
- You can work on computers from the 3rd day of your treatment.
- You can take bath down from your shoulders from the day after surgery.
- You can wipe and clean your face away from the eye.
- Use protective sunglasses when you go out for at least 2 weeks after procedure
- Do not expose your eyes to dust.
- Do not touch or rub your eyes.

Glaucoma is a disease that gets worse with time if proper care is not taken. It is a condition that causes damage to your eye’s optic nerve. Glaucoma is often the result of pressure that builds inside the eye. Most of the times a hereditary disease, it may not show up until later in life.
The increased in pressure called as the intraocular pressure causes damage to the optic nerve, simply put optic nerve transmits images to the brain. if the damage to the eyes due to high pressure continues, Glaucoma can cause permanent damage to the eyes and hence immediate and proper care need to be taken.
Glaucoma develops through the years and not many people experience any symptoms of glaucoma. The first and foremost sign of Glaucoma is loss of peripheral or side vision, which can go unnoticed till a very later stage. Glaucoma is one of the most serious reasons you should have a complete eye examination from a specialist once a year which greatly helps in detecting the signs of glaucoma. Some of the common symptoms of glaucoma are seeing halos around lights, vision loss, redness in the eye, eye that looks hazy (particularly in infants), nausea or vomiting, pain in the eye, narrowing of vision (tunnel vision). Glaucoma can be treated with prescribed eye drops, laser surgery or microsurgery.
Eye drops for glaucoma are available in two forms ones that reduce the formation of fluid in the front of the eye and the ones that reduce the outflow. Though a treatment the eye drops for Glaucoma can have side effects like allergy, redness of the eyes, brief stinging, blurred vision, and irritated eyes. Laser surgery increases the outflow of fluid from the eye in open-angle glaucoma or eliminates fluid blockage in angle-closure glaucoma. Laser surgery may be a trabeculoplasty where laser is used to pull open the trabecular meshwork drainage area; or a iridotomy where a tiny hole is made in the iris that allows the fluid to flow more easily or a cyclophotocoagulation in which a laser is used to treat the middle layer of the eye, reducing the production of fluid.
Microsurgery for glaucoma is called a trabeculectomy where a new channel is created to drain the fluid thus reducing intraocular pressure that causes glaucoma. For some patients a glaucoma implant is the best option. The only way to prevent or control glaucoma is if it is diagnosed and treated early
