Tip of the Week: Donate eyes to see the world even after you left.
Services - Cataract & Phaco
Clouding or haziness of the normal lens of eye is called Cataract. A middle aged person experiencing painless progressive loss of vision probably suffers from Cataract.
At Grewal Eye Institute, Cataract surgery is done by the sophisticated Phacoemulsification (stitchless surgery) technique.
GEI has been among the first to introduce this surgery in 1993. The institute offers facilities for ultra sonography in a diagnostic, biometry and pachymetry mode. It helps in calculating the power of IOL for Intra Ocular Lens Implant as well as to assess the posterior segment in cases with hazy media.
All you need to know about Cataract & Phaco
Modern Cataract Surgery
Cataract surgery is performed routinely every day throughout the world. It is one of the most mechanically advanced areas of medicine. Yet, many patients still have fears and misunderstandings about this surgical procedure. The following review is designed to provide a basis for understanding the modern treatment of Cataract.
A Brief History
Cataract surgery is not a new treatment. The removal of a 'clouded lens of the eye' dates back to the ancient Babylonians. The Cataract surgery that your parents may have had was often a very trying ordeal with a long hospital stay, considerable discomfort and an even longer recovery period. Today, the development of advanced surgical techniques and intraocular lenses have made Cataract surgery one of the most successful forms of treatment offered by the medical profession. The operation is virtually painless and has a recovery period of a few days. The vision procided by an intraocular lens is as clear as that provided by the natural lens of the eye.
A cataract is a cloudiness or opacityof the eye's natural clear lens. It obstructs the passage of light to the retina (Parda) of the eye and impairs vision. When the lens develops cloudiness to the point that it impairs vision, it is called Cataract. It is like looking through a frosted glass
Prevention of Cataract
Although research is currently underway, no preventive measures are known for cataracts that develop with age. No diet, drugs or medicines have been proven to delay or cure the developing cataract. A safe surgical procedure, however coupled with the appropriate corrective lenses, has restored sight for millions.
Techniques of Cataract Surgery
Cataract surgery can be done by a conventional technique (Large incision) or Phaco-emulsification (Small Incision/No-Stitch surgery).
  1. Conventional Surgery
  2. Traditional cataract surgery requires a large incision that spans the third of the circumference of the cornea (7-9mm). The cloudy lens is removed as a single piece. As many as seven stitches are required to close it after implanting an IOL (Intra Ocular Lens). One has to use pad bandage, dark glasses and eye shield and take recommend precautions in the post operative period for up to six weeks.

  3. Phacoemulsification (Phaco) (small incision) surgery
  4. It is a no stitch small incision cataract surgery. IOL is implanted and the wound is closed without any stitches.

    A microprocessor controlled Phacoemulsification 'PHACO' machine with tiny ultrasonic probe is used to remove cataract and to insert the lens implant through the smallest possible opening in the eye. PHACO uses ultrasound energy to liquefy lens and suck it out with a titanium probe vibrating forty thousand times a second. The minute incision is self sealing and needs no suture or stitch to close it. The patient is back to normal activities within a few days, including attending office or even doing heavy manual work.

    Phacoemulsification was started for the first time at Chandigarh in 1993 at Grewal Eye Institute. At present this technique is used for all cases undergoing surgery at Grewal Eye Institute. To retain the maximum benefit of the miniature 2.8 mm incision, a foldable IOL is used at present. The foldable IOL made of transparent silicone or acrylic polymer is inserted in eye through a needle and unfolds to its full size once it is inside the eye.

Benefits of Phaco surgery?
  • Return home within hours of the procedures without bandage.
  • Fast recovery of good vision in a matter of days instead of weeks or even months.
  • Minimal restriction on activities i.e. normal household, recreational and even occupational activities may be resumed within a day or two.
  • No bandage, no dark glasses, no restrictions and no precautions.
  • Final spectacles at two weeks, Immediate provision of temporary reading glasses if desired.
  • Reduces the change of surgically induced astigmatism.
  • No wound or suture related compliations.
  • Yields a stronger eye resistant to injuries.
  • Less inflammation after the surgery.
Removal of Cataract
Under ordinary circumstances, cataract surgery is not an emergency situation. There are only few, rare, instances where immediate action is indicated. Examples of these emergencies might be if the cataract causes glaucoma or if an eye is severely inflamed. Otherwise, the choice of whether and when to have surgery is up to the patient.
Cataract usually form slowly, but surgery may be performed as soon as visual disability cause by the cataract begins to affects your quality of life. Some points to consider are -
- Is your work affected by deteriorating sight?
