External transscleral posterior chamber lens fixation

Area of Science:

• Ophthalmology
• Surgical Innovation
• Intraocular Lens Implantation

Background:

• Complications arise with anterior chamber and iris-fixated lenses when capsular support is inadequate.
• Current transscleral fixation methods often lack direct visualization and risk ocular structure damage.

Purpose of the Study:

• To present a new, safer method for suture fixation of posterior chamber intraocular lenses (PCIOLs) in the ciliary sulcus.
• To overcome limitations of existing transscleral fixation techniques.

Main Methods:

• Developed a measured external transscleral suture fixation technique for PCIOLs.
• Sutures are placed externally and guided into the ciliary sulcus under direct visualization.
• This method avoids passing needles through the corneoscleral wound.

Main Results:

• The new technique allows for more predictable suture placement within the ciliary sulcus.
• It minimizes the risk of damage to the corneal endothelium, ciliary body, and other intraocular structures.
• Offers a safer alternative for patients with inadequate capsular or zonular support.

Conclusions:

• This measured external transscleral suture fixation is a valuable advancement for PCIOL implantation.
• The technique enhances safety and predictability, particularly in complex cases requiring lens support.
• It represents an improvement over traditional transscleral fixation methods.
