Cataract Eye Surgery


Cataract surgery is the removal of the natural lens of the eye (also called "crystalline lens") that has developed an opacification, which is referred to as a cataract. Metabolic changes of the crystalline lens fibers over the time lead to the development of the cataract and loss of transparency, causing impairment or loss of vision. During cataract surgery, a patient's cloudy natural lens is removed and replaced with a synthetic lens to restore the lens's transparency.

Phacoemulsification (Phaco) is the preferred method in most cases. It involves the use of a machine with an ultrasonic handpiece equipped with a titanium or steel tip. The tip vibrates at ultrasonic frequency (40,000 Hz) and the lens material is emulsified. A second fine instrument (sometimes called a cracker or chopper) may be used from a side port to facilitate cracking or chopping of the nucleus into smaller pieces. Fragmentation into smaller pieces makes emulsification easier, as well as the aspiration of cortical material (soft part of the lens around the nucleus). After phacoemulsification of the lens nucleus and cortical material is completed, a dual irrigation-aspiration (I-A) probe or a bimanual I-A system is used to aspirate out the remaining peripheral cortical material.

This Lens is preferred for patient having cylindrical power. Usually this lens is suggested if cylinder is more than 1.5 D

Accommodating Lens


Like naturel lens, this lenceincrese it’s power while doing hear work. So, patients don’t need to depend on spectacles for near works.

Multifocal Lens

  • These types of lens consist of multiple rings.
  • Through every ring, things are seen clear at different distance.
  • Patient’s brain adapts this lens within a few days after surgery and he\she is able to see at hear & distance without spectacles
