Complex Cataract Surgery

What is Complex Cataract Surgery?

Complex cataract surgery is a procedure used to treat cataracts in people who have other eye factors alongside their cataracts (listed below).  Complex cataract surgery requires more detailed pre-operative preparation and surgical expertise than basic cataract surgery.

A complex cataract removal procedure requires devices and techniques that are not commonly used in routine surgery. Also, may require additional steps or surgical expertise.

Factors Which Make Cataract Surgery a Complex Procedure

Several factors can add challenges to cataract surgery. This can be due to:

  • Previous eye trauma or injury
  • Previous retinal surgery
  • Macular degeneration
  • Previous treatment with eye injections
  • Very dense or white cataracts
  • Small pupil
  • High Myopia
  • Previous uveitis (eye inflammation)
  • Glaucoma (and related condition as narrow angles or Pseudoexfoliation)
  • Floppy iris syndrome (seen in people using Tamsulosin for enlarged prostate treatment or doxazosin for high blood pressure treatment)
  • Fuchs’ dystrophy
  • Lens subluxation (the support structure of the lens is too weak)
  • Congenital eye abnormalities

How is the Surgery Performed?

Like a normal cataract removal operation, complex cataract surgery is also expected to improve the patient’s vision as well as his overall quality of life.
Cataract surgery is normally an outpatient procedure, and most complex surgeries can also be performed on an outpatient basis, under local anaesthetic. The normal procedure only takes around 10 minutes, a complex surgery takes longer due to the additional steps required. The steps involved in a complex cataract surgery tend to differ for each unique case in order to respond to the factors that necessitated the complex procedure in the first place.

People with such complex cataracts require meticulous surgical planning and counselling.

For example, some patients have small pupils and the pupil does not dilate properly. Therefore, special techniques are necessary to dilate the pupil to allow for cataract surgery.  Once the pupil is successfully dilated, the surgeon will access the cataract and remove it. Thanks to advanced surgical technology, there are different methods to deal with a small pupil.

Techniques to dilate small pupil

Some patients have unstable lenses inside the eye. This will require an additional device called a “capsular tension ring” or occasionally special sutures to support the new lens implant.

Occasionally, this can be associated with other eye abnormalities such as a lens or iris coloboma (congenital defect) that require repair at the same time.
