CATARACT
   
 
Any opacity of the crystalline lens and its capsule, causing visual impairment, is called cataract.                      
   

Symptoms of Cataract:

  • Decrease of vision for far and near.
  • Dimness of vision for distance with good near vision without glasses

     
 
2.

What causes Cataract ?

     
   

Ageing is the most common cause. With age, proteins of the eye lens get altered and opacified leading to cataract. Other causes include congenital and developmental anomalies, trauma, inflammation of the eye, metabolic diseases like Diabetes, Hypothyroidism etc.

   

     
 
3.

What are the common symptoms of CATARACT?

   
 

 

 
Cataract makes simple tasks difficult and in some cases impossible to perform. 

There are two options available for cataract surgery : 

 

1) Conventional Cataract surgery or Extra Capsular Cataract Extraction (SICS/ECCE)

  • Injections are given near the eye
  • Requires an incision of 7-8 mm
  • The cloudy eye lens is removed in one piece   
  • A hard plastic lens is implanted
  • Multiple Stitches are required in ECCE
  • Final glass prescription could take even up to 10 weeks
     
   

2) Microincision Cataract Surgery (PHACOEMULSIFICATION)

     
   
  • Requires a very small incision of 1.5 - 2.8mm
   
  • Cataract Extraction with Phacoemulsification is followed by foldable lens implantation
   
   
    • Walk-in Walk-out procedure      
   
    • Stitchless, bloodless, painless surgery
   
    • Chances of infection are very low
   
    • Minimum post surgery precautions
   
    • Quicker healing and recovery 
     
 
4.

When to go for Cataract removal? 

     
   
Cataract should be removed as soon as it begins to affect daily activities. With any of the above mentioned symptoms setting in, it is the right time to go for Cataract removal. DO NOT WAIT FOR THE CATARACT TO GET MATURE as unnecessary delay can lead to avoidable complications and more difficult surgery. Cataract surgery can be undertaken successfully in any season. Summer or rainy seasons have absolutely no effect on the outcome of the cataract surgery. 
     
 
5.

What is the recommended treatment for cataract? 

     
    With phacoemulsification and implantation of foldable Intra Ocular Lens (IOL), treatment of cataract has become very simple and sophisticated. The procedure is safe, accurate and leads to rapid recovery. Thus phacoemulsification with foldable lens implant is the most recommended treatment for cataract. 
     
 
6.

What is phacoemulsification with foldable IOL?

 
In phacoemulsification, ultrasound power is used to break the hard cataract into minute pieces, which are then sucked out through a small 1.5-2.8mm incision. A foldable lens (IOL) of the required power is then implanted. The soft construction allows the lens implant to be folded for insertion through a 1.5 to 2.8mm micro incision. Once in place, the lens unfolds to its regular size of 6 mm. 
 

 

   
 
7.
What are the advantages of phacoemulsification with foldable IOL over conventional cataract surgery ?
 
  • It allows for a injectionless, stitchless, painless, no bandage surgery
    • Drops of local anaesthetic agent are used instead of an injection in the eye, thus leading to a walk-in walk out procedure
    • Early visual rehabilitation for the patient
      • Minimum curvatural changes occur in the eye following surgery
    • Post surgery, the wound is very secure
  • Final glasses can be prescribed within one weeks

9.
How soon after phaco surgery, will I be able to see?
 
In some cases, the patient is able to see almost immediately following the surgery, although most patients experience clear vision after one or two days

 

   
 
10.
Will I need glasses after phaco surgery?
 
  • You may need to wear glasses only to fine -tune your vision
  • These spectacles have normal lenses unlike thick lenses used in the past.
  • If unifocal IOL is used, near vision glasses are almost always required. 
 

 

   
 
11.

Is there any diet restriction after phaco surgery?

 
  • There are absolutely no diet restrictions after phaco and you can continue with your normal diet.
  • However, diet regulation advised for other diseases like Diabetes, High blood pressure, etc must continue. 
 

 

   
 
12.

Can I have phaco surgery on one eye even if the other eye had been operated upon by the conventional surgery ?

 

  Yes, you may have micro incision Phaco surgery on your "Second Eye" provided     there is no specific contraindication for Phaco.
