Cataract is an inevitable part of growing old. But, the good news is that it can be treated through hassle-free, bladeless Cataract Surgery. At Sharp Sight Eye Hospital, we offer reliable and safest cataract surgery through both conventional and advanced laser techniques, which assure excellent visual results. The surgery barely takes 15 minutes and during the procedure, the cataract-affected lens is removed painlessly and replaced with an artificial lens, called the Intraocular Lens (IOL).


Cataracts are clouding the natural, clear lens of the eye. It usually develops as we age, but occasionally, cataract formation may be seen in newborn babies and young ones too. These congenital cataracts could be the result of genetic tendencies, drug reaction caused during the developmental stage, eye infection, trauma or injury, etc. However, whatever may be the cause, cataract leads to a double or blurred vision making it difficult for an individual to perform his/her daily chores.

As a caution, you should never let cataract become too severe, as any delay in seeking proper and timely treatment may leave you visually impaired for the rest of your life.

  • Patients can resume daily activities like watching TV, computer, reading, etc., immediately.

Traditional Intraocular Cataract Lenses or IOLs, have been spherically aberrated, which means their front and back surfaces are uniformly curved. Hence all the light rays are focused at varying points forming slightly blurred images. Intra Ocular lenses have evolved with time to give better clarity at varying distances and lighting conditions.

Aspheric IOLs, are slightly flat in the periphery and are designed to provide better contrast sensitivity and better vision in low light conditions. They achieve this by focusing all the light rays at one common point and forming a crisp aberration-free image.

These lenses give a better visual perception even in low light conditions and are theoretically known to give a better color resolution to the implanted eye. In addition, they are also known to offer many other advantages apart from the ones mentioned above.


While a normal eye would have a smooth, round cornea and lens, people with astigmatism have an irregularity in their cornea or lens in a particular axis. Astigmatism is a common refractive error that causes blurred vision without the use of glasses or contact lenses.

When undergoing cataract surgery, astigmatism less than ID can be corrected using unique incisions but astigmatism more than ID will need implantation of a special IOL which has the correction added in that axis.


  1. This single-piece foldable lens is flexible and comfortable for the human eye.
  2. Toric lens implantation for cataract surgery has shown positive reviews in terms of both optical performance and higher quality vision.
  3. It reduces dependency on distance glasses.

Monofocal lens has the ability to focus objects from only on one distance. Revolutionary Multifocal lenses focus both near and distant objects, thus making it easier for patients to reduce their dependency on glasses. 92% of the cataract patients after receiving multifocal intraocular implants report that they “never or occasionally” use spectacles for their daily routine life.


These lenses are an excellent choice for intermediate and distance vision. Near vision is acceptable except for fine print, such as grocery labels or medicine labels, etc. However, patients usually resort to this problem by keeping a pair of near vision spectacles handy. With Refractive Multifocal IOL, patients may experience glare and haloes around lights at night but using night driving spectacles helps them to get rid of the problem.


When it comes to providing both reading and distance vision, these implants are an excellent choice. The intermediate vision is acceptable but for long duration of computer work, where glasses come handy. Patients experience lesser glares & haloes around lights at night. However, many patients get accustomed to this drawback or as an alternative they use night driving spectacles, to combat this.


IOL is not suitable for cataract patients with:

  • Severe retinal problems like Retinal Detachment, Macular Degeneration, Macular Holes, Diabetic Retinopathy, etc.
  • Advanced Glaucoma.
  • Cornea problems such as Keratoconus, irregular Corneal Astigmatism, etc.
  • Patients who have undergone procedures such as LASIK, PRK etc.

Frequently Ask Questions About Cataract Surgery

What is cataract and how does it affect our vision?

Cataract is clouding of the natural lens of the eye and it is an inevitable part of ageing. And, when the light passes through the cataract or cloudy lens, it gets blocked or distorted which leads to the formation of a blurred image on the retina. As a result, cataract development causes impaired night vision, affects color sharpness and gradually makes it difficult for an individual to perform his/her daily chores.

What are the common causes of cataract?

Development of cataract is considered to be a normal part of ageing. Unless present in the newborn as a developmental defect or caused due to an eye injury, any individual who is 60 years and above has a tendency to develop a cataract.

What are common signs of cataract to watch out for?

  • Blurred, cloudy or distorted vision
  • Poor night vision
  • Light sensitivity
  • Trouble reading/watching TV
  • Glare/halos
  • Double vision
  • Color distortion

If you experience any of the above symptoms, it’s time you get your eyes examined by a cataract specialist.

How is cataract treated?

Cataract surgery, which is the only possible way to get rid of cataract can be performed the moment an individual feels it has started affecting his/her vision or is causing hindrance in performing daily activities. There are various procedures like conventional cataract surgery, Femto Laser-Assisted cataract surgery (FLACS), Zepto-assisted cataract surgery, etc., through which cataract-affected lens can be removed. These surgeries are 100% safe and offer excellent results.

Is there any best time for cataract surgery?

Ideally, cataract surgery should be performed the moment an individual feels it has started affecting his/her vision or is causing hindrance in performing daily activities. The weather conditions like heat, humidity or rains have no effect on the outcome or performance of the surgical procedure.

Is it possible for a diabetic to undergo cataract surgery?

Yes, diabetics can safely undergo cataract surgery, provided their blood sugar levels are under control.

How is cataract surgery performed and is it a painful procedure?

During cataract surgery, the natural lens of the eye which gets cloudy and hardened is removed and replaced with an artificial lens called an intraocular lens, or IOL to restore clear vision. Depending on the patient’s preference, it can be performed either with the help of lasers or through the traditional technique. However, the latest Femtosecond Laser Technique is 100% bladeless, bloodless, painless and safe. It is performed on an outpatient basis and does not require an overnight stay in a hospital.

Can all patients having a cataract undergo microincision phaco surgery?

Eye surgeon or cataract specialist is the best person to judge and decide if the patient is well-suited to undergo microincision phaco-surgery. However, cataract patients at Sharp Sight, one of the best cataract hospital in Delhi NCR are first thoroughly examined with latest and state of the art diagnostic equipment. Our goal is to achieve excellent visual results.

What are the various types of intraocular lenses (IOLs) available these days?

  • Monofocal IOL: These lenses provide good distance vision and most patients are not dependent on their distance glasses for daily activities. However, patients implanted with Monofocal IOLs require reading glasses after cataract surgery. Lately, Monofocal lenses have improved image quality by enhancing contrast, eliminating glare, and improving night vision.
  • Toric IOL: These lenses correct high cylindrical power by reducing the patient’s dependence on distance glasses.
  • Multifocal IOL and Accomodating IOL: These lenses are designed to provide distance and near vision with less dependence on glasses.

At Sharp Sight, we have a range of best cataract lenses in India. Our experts help you choose an IOL that highly suits your daily needs.

What is the life of an intraocular lens and how safe are these?

Once the IOL is implanted in the eye, it usually lasts a lifetime. And, these IOLs are safe enough to be implanted in any individual post cataract surgery, irrespective of their health ailments, like diabetes, hypertension, etc.

Can cataract be treated with lasers and what is femtosecond bladeless cataract surgery?

Laser-assisted cataract surgery uses a Femtosecond Laser Technology to break and remove cataracts with utmost precision, accuracy and without any use of the blade. Cataracts treated with laser technology are 100% bladefree, painless and stitchless, and it requires no hospitalisation and no bandage.

Is femtosecond bladeless cataract surgery different from traditional cataract surgery?

Conventional cataract surgery is very different from the new-age laser-assisted cataract surgery. Firstly, during traditional surgery, the cataract-affected lens is broken up manually using ultrasound which may be little traumatic for a patient. Secondly, during this surgery incision is made with the help of blade. Whereas, while performing the Bladeless surgery, Femto laser assists surgeon throughout the surgery, right from fragmenting lens into smaller pieces to making entry parts. Besides, laser-assisted cataract surgeries are no-blade, no-pain, and no-stitch surgery.

What are the advantages of femtosecond laser assisted cataract surgery?

The Femtosecond Laser Technology assists the surgeon during specific steps of cataract surgery which has brought new levels of safety, accuracy, and predictability to cataract removal procedure. This results in a high precision, painless surgery. At Sharp Sight, we offer the best treatment for cataract through Femto laser cataract surgery and we have some of the best doctors for cataract surgery in Delhi.

Apart from getting rid of cataract, are there any other benefits of a cataract surgery?

Cataract surgery has many benefits like vision becomes sharp and crystal clear, one can almost immediately resume doing activities such as driving, reading and watching TV, etc. In short, post-cataract surgery, a patient can lead a life without being totally dependent on glasses.
