Cataract Eye Surgery in IndiaCataract surgery is the medical procedure of removing the natural lens of the eye (crystalline lens) that has developed opacification or cloud which is also termed- cataract. Cataract is caused by metabolic changes of the natural lens fibers over time. These lead to the development of cataract and loss of transparency, increasing blurriness and causing loss of vision. Very often a patient's first symptoms are strong glares in the nighttime from lights along with reduced acuity at levels of low light. During the cataract surgery procedure, a patient's cloudy natural lens is surgically removed and then replaced with a synthetic lens to restore the lens's natural transparency. Within a few days of recovery the patients gets back his normal vision and can get back to routine.
Types of cataract surgery available in India:-
Phacoemulsification or Phaco is the preferred method for Cataract surgery in many cases. Phaco involves the use of a machine with an ultrasonic handpiece equipped with a titanium or steel tip. The tip vibrates at high frequencies (40,000 Hz) and the lens material is emulsified. A second instrument (also known as 'cracker' or 'chopper') may be used to facilitate cracking/chopping of the nucleus into smaller sections .
Conventional extracapsular cataract extraction (ECCE)- The Extracapsular cataract extraction procedure involves the removal of the natural lens while the elastic lens capsule (posterior capsule) is left intact, permitting the implantation of an intraocular lens.
Intracapsular cataract extraction (ICCE). This procedure comprises removal of the lens and the surrounding lens capsule as one piece. This procedure often has complications due to the large incision required and the pressure that gets exerted on the vitreous body. ICCE is not commonly performed.
