Cataract surgery has evolved significantly, with phacoemulsification and smaller incisions becoming standard. These advancements improve safety, efficiency, and patient visual recovery after cataract removal.

Area of Science:

  • Ophthalmology
  • Surgical Innovation

Background:

  • Cataract surgery has undergone major advancements over the last 30 years.
  • Shift from intracapsular cataract extraction to extracapsular techniques, particularly phacoemulsification.

Observation:

  • Phacoemulsification, proposed over 20 years ago, has gained popularity due to improved techniques and equipment.
  • Development of viscoelastic agents and improved surgical methods for capsule management.
  • Advances in wound construction enable sutureless repairs and faster recovery.

Findings:

  • Modern phacoemulsification offers increased safety and efficiency in cataract removal.
  • Smaller incisions and foldable intraocular lenses enhance visual recovery times.
  • Posterior chamber nucleus removal minimizes corneal endothelium damage.
