Summary

Ophthalmic viscoelastic agents are divided into cohesive and dispersive types. Combining both using the soft shell technique optimizes surgical space management and anterior chamber maintenance.

Area of Science:

  • Ophthalmology
  • Surgical Science

Background:

  • Ophthalmic viscoelastic agents are crucial in ophthalmic surgery.
  • These agents are classified into cohesive and dispersive types based on physical properties.

Purpose of the Study:

  • To categorize ophthalmic viscoelastic agents based on physical properties.
  • To introduce the viscoelastic soft shell technique for enhanced surgical outcomes.

Main Methods:

  • Classification of viscoelastic agents into higher-viscosity cohesive and lower-viscosity dispersive groups.
  • Application of the viscoelastic soft shell technique, combining both agent types sequentially.

Main Results:

  • Higher-viscosity cohesive agents excel at creating and maintaining surgical space.
  • Lower-viscosity dispersive agents offer better retention in the anterior chamber and space partitioning.
  • The soft shell technique synergistically utilizes the benefits of both agent types.

Conclusions:

  • The viscoelastic soft shell technique effectively leverages the distinct advantages of cohesive and dispersive agents.
  • This technique optimizes space management and anterior chamber stability during ophthalmic procedures.
