[Liquid perfluorocarbons in surgery for lens subluxation]

Area of Science:

• Ophthalmology
• Surgical Innovation
• Biomaterials

Context:

• Dislocated lenses pose a significant surgical challenge.
• Traditional methods may involve extensive intraocular manipulation.
• Posterior chamber lens luxation requires specialized removal techniques.

Purpose:

• To evaluate the efficacy of liquid perfluorocarbons (PFCs) for lens removal from the vitreous cavity.
• To assess the safety and benefits of PFCs in managing dislocated lenses.
• To establish PFCs as a preferred method for specific lens dislocation scenarios.

Summary:

• Liquid perfluorocarbons (PFCs), characterized by high specific weight and low viscosity, were utilized in four patients with dislocated lenses.
• In three cases, PFCs facilitated the removal of firm nucleus lenses dislocated into the vitreous following contusion.
• In one case, PFCs aided in the removal of a dislocated posterior chamber intraocular lens.

Impact:

• Liquid PFCs provide a simple and gentle approach for removing dislocated lenses from the vitreous cavity.
• This technique significantly minimizes instrument manipulation within the vitreous, reducing surgical trauma.
• The use of PFCs is associated with a minimal risk of surgical and postoperative retinal complications, outweighing their cost.
