Intraocular lens scaffold

Glued IOL scaffold technique.

IOL scaffold for Sommering's ring.

An intraocular lens scaffold is a surgical technique used in ophthalmology to manage complex cases of cataract surgery where there is a deficiency of the capsular bag support. This technique involves the use of an intraocular lens (IOL) to provide structural support during the surgical procedure.

IOL scaffold for IOFB removal.

Surgical Technique

The intraocular lens scaffold technique is primarily used in cases where there is a compromised capsular bag, such as in zonular weakness or capsular rupture. The technique involves the placement of an IOL in the anterior chamber to act as a scaffold, allowing for the safe removal of the cataract and the implantation of a secondary IOL.

Indications

The IOL scaffold technique is indicated in cases of:

• Zonular dehiscence
• Posterior capsule rupture
• Subluxated lens
• Intraocular foreign body (IOFB) removal

Procedure

1. Initial Assessment: The surgeon assesses the extent of capsular support loss. 2. IOL Placement: An IOL is placed in the anterior chamber to provide a scaffold. 3. Cataract Removal: The cataract is emulsified and removed using phacoemulsification. 4. Secondary IOL Implantation: A secondary IOL is implanted in the capsular bag or sulcus.

Variations

• Glued IOL Scaffold: This variation involves the use of fibrin glue to secure the IOL in cases of severe zonular weakness.

• IOL Scaffold for Sommering's Ring: Used to manage Sommering's ring, a condition where residual lens material forms a ring in the capsular bag.

• IOL Scaffold for IOFB Removal: Utilized in cases where an intraocular foreign body needs to be removed safely.

Advantages

The intraocular lens scaffold technique offers several advantages:

• Provides structural support in the absence of capsular support.
• Allows for safe cataract removal and IOL implantation.
• Reduces the risk of vitreous loss and other complications.

Limitations

Despite its advantages, the IOL scaffold technique has limitations:

• Requires surgical expertise and experience.
• Potential for increased intraocular pressure postoperatively.
• Risk of endothelial cell loss due to anterior chamber manipulation.
