Advanced Cataracts Surgery System

Cataract Surgery the most common procedures performed on a regular basis by ophthalmologists. Cataract surgery is done by phacoemulsification using the small incision technique. Infact the smallest incision possible is made so that the unwanted lens material can be removed with an ultrasonic machine.

This cataract removal procedure is performed on an outpatient basis. Anesthetic eye drops are administered in the eye to make it numb. With the use of an operating microscope, a very small incision is made in the surface of the eye in or near the cornea. A normal incision is about 2 millimeters in length and is created at the junction of the cornea and the sclera.


Front part of the lens, known as the lens capsule, is delicately opened and the unwanted lens material is removed. A thin ultrasound probe is inserted into the eye ultrasonic vibrations are used to dissolve the clouded lens. As the materials are destroyed a vacuum is used to remove them from the eye. These tiny fragmented pieces are suctioned out through the same ultrasound probe. Once the cataract is removed, an artificial lens is placed into the thin capsular bag that the cataract previously occupied. This lens is essential to help your eye see clearly after surgery. 



Once the cataract has been successfully removed from the eye an intraocular lens (IOL) is implanted through the same incision. The lens is then put into the lens capsule and centered. The IOL remains permanently inside the eye in this location. IOLs cannot be felt or sensed in any way by the patient. There are various kinds of IOL’s and their significance is discussed with the patient.



In the past, cataract patients only had the option of a monofocal intraocular lens implant. Monofocal meant that they would only be correct vision for near or far and would most likely still require glasses. In recent years several advanced lens implants are used by ophthalmologists for cataract patients. The advance intraocular lenses have the advantage of allowing people to be able to see both near and far distances after surgery. If you have worn glasses, this might be an opportunity to see better without glasses. The main difference between the conventional and new IOLs is in the ability to focus at multiple distances.


Premium Intra Ocular Lenses

Modern cataract surgery is more sophisticated than simply clearing the line of vision from a cloudy cataract lens. Technology thesedays allows cataract surgeons to not only improve vision clarity, but also enhance the quality of vision.

Traditional cataract lens implants may induce so-called ‘higher order aberrations’. Higher order aberrations may cause visual symptoms including night-time driving glare, haloes, and reduced contrast sensitivity. Aspheric lens implants take into account an individual’s eye anatomy, particularly the shape of the front clear part of the eye, the cornea. Aspheric implants reduce higher order aberrations and maximize the quality of vision. Many patients report that the reduced symptoms of glare and halos afforded by an aspheric lens provide vision similar to twenty years before surgery.

Multi Focal Intra Ocular Lenses


Multifocal IOLs are made up of concentric circles that allow for multiple points of focus at distance, intermediate, and near. As with standard IOLs, a multifocal IOL also replaces cataract. The difference being that the multifocal design provides patients with the ability to see images clearly at a number of distances, not just one as with a standard IOL. For many patients, having a multifocal lens implant means that you will be able to see at distance, up close, and everywhere in between, without being dependent on glasses. Patients with multifocal lens implant can drive, watch television, read or do crafts-without the need for glasses.

The AcrySof ReSTOR lens is a multifocal IOL that represents breakthrough technology because of its unique, patented optic design, which allows patients to experience the highest level of freedom from glasses ever achieved in IOL clinical trials.

The AcrySof ReSTOR IOL uses a combination of three complementary technologies: apodization, diffraction and refraction, to allow patients to experience a full range of vision without the need for reading glasses or bifocals. This range of vision without glasses is achieved through the optical properties of the IOL.

The benefit for patients is a high level of spectacle independence. Alcon has patented the application of apodization technology to an IOL, making the AcrySof ReSTOR lens the first and only apodized diffractive IOL.



Astigmatism is a common vision disorder where light does not reach the retina properly because of an irregular shape. Patients with astigmatism will see a shadow or smear of an image that they are looking at. Astigmatism may occur with patients who suffer from nearsightedness and farsightedness, and will cause objects to appear unclear. An untreated astigmatism may cause eye strains or headaches if untreated. Astigmatisms are easily treated with glasses or contact lenses. Depending on your level of astigmatism, we will make a recommendation as to which will work best for you.

What is astigmatism?

An astigmatism is a refractive error that causes light to focus at different points in the eye. Since the light is focusing at different points, a blurring affect is created at both near and far distances. Astigmatisms can be caused by the shape or curvature of the cornea being more of the shape of a football rather than spherical like a normal cornea.

There are two types of astigmatism: regular and irregular. A regular astigmatism, which is the dominant form of astigmatism, occurs when the part of the eye which needs the most amount of power is located 90 degrees away from the area in the eye that needs the least amount of power. It is symmetrical which is easy to correct with glasses and contacts. In an irregular astigmatism, the cornea may not always be smooth  it may be asymmetric. This causes light to scatter throughout the eye with many different focus points. Neither glasses nor soft contacts can correct this condition and rigid gas permeable lenses are often medical necessity for better vision.

How is astigmatism detected?

It is easy to identify an astigmatism by two common. The first test is a keratometry, which measures the two main curvatures of the cornea. The keratometry is important if you are going to fitted for contact lenses. The second exam is refraction. During this part of the exam you choose between the variety of glasses and contact lenses. Topography is another exam that is not commonly used but it provides a detailed map of the cornea. Topography is good if you are seeking cataract surgery or if you have an irregular astigmatism.

The two structures of the eye that focus light and allow for perfect vision are the cornea and the lens. In cataract surgery, the lens of the eye is replaced with an artificial lens. The artificial lens that is placed in the eye has a prescription that can allow for clear vision without glasses. However, if a patient has astigmatism, glasses will still be required to correct the astigmatism and provide clear vision.


With the latest advances in IOL technology, having clear vision without glasses is now possible even in patients with significant amounts of astigmatism.


Toric Intra Ocular Lenses

We offer the latest advances in astigmatic cataract correction. Utilizing a revolutionary intraocular lens implant, toric IOLs provide built-in astigmatism correction, greatly reducing the need for glasses after surgery. This lens implant is based on the same technology as the standard intraocular lens implant, made with the same materials and by the same company. Implanting the toric IOL requires aligning the lens in the appropriate orientation, but there is otherwise no deviation from a standard cataract surgery. The post-operative care is also the same as with a standard intra-ocular lens. If you are interested to hear more about this lens upgrade, please inform us, and our surgeons will determine if you are a candidate for this exciting technology. Now a multifocal IOL with Toric correction is also available which can correct both astigmatism and far and near distance vision.

Post Cataract Surgery Instructions
  • If you should experience persistent or severe pain in the operated eye or progressive loss of sight in the eye, sudden flashing lights or burst of floaters contact us immediately. Call 041-2616164 during business hours, or at night. The doctor will arrange to see you immediately, and can get in touch with the consultants.
  • Wear the goggles to bed at night for two weeks and continue wearing them during the day.
  • You may sleep on either side with as many or as few pillows as you wish as long as you are wearing the shield.
  • Wash hair with head back only for one week. It's OK to shower, but avoid soap or shampoo in the operated eye, and be careful not to rub it in the shower.
  • Avoid lifting above 10 pounds for two weeks (if you are straining very hard to lift, it's too heavy; if it's easy to lift, it's OK.)
  • Allow at least 5 minutes between using the different drops. You can gently pull down your lower lid, pressing on the cheekbone, to get more room to put in the drops, but don't touch your upper lid.

Unless otherwise directed, For Cataract Patients:

  • Follow-up appointments will be advised on the first post-op day.
  • Pred-Forte (steroid; milky liquid;) & Vigamox (antibiotic; yellowish fluid) - one drop of each every 3 hours during waking hours.
