Remnant extraction by using an intraocular lens injector with essential flow

Area of Science:

• Ophthalmology
• Surgical Techniques
• Cataract Surgery

Background:

• Posterior capsular rupture during cataract surgery can lead to retained lens fragments.
• Soemmering rings, formed from epithelial cells, can complicate intraocular lens removal.

Observation:

• A new technique utilizes an intraocular lens (IOL) injector inserted into the anterior chamber as an exit for residual lens fragments.
• Passive fluid flow, from an anterior chamber maintainer or ocular viscoelastic device (OVD) injection, assists in directing fragments into the injector lumen.
• Assisting devices like a phaco-chopper or vitreous cutter can be used in conjunction with the fluid flow and injector.

Findings:

• This method allows safe removal of Soemmering rings, even when located under the iris, through small incisions.
• Retained nucleus fragments in the anterior chamber are safely removed.
• Fragments that descend into the vitreous cavity can be brought to the anterior chamber for removal via passive flow.

Implications:

• The described technique, "remnant extraction through lens injector with essential flow," offers practical benefits over existing methods.
• Advantages include reduced need for OVD injection and the use of smaller incision sizes.
• This technique presents a viable alternative for managing retained fragments and Soemmering rings following complicated cataract surgery.
