Trailing-haptic-first modification of double-needle intrascleral haptic fixation technique

Area of Science:

• Ophthalmology
• Surgical Techniques

Background:

• Posterior chamber intraocular lens (IOL) fixation often requires adequate capsule support.
• The Yamane double-needle intrascleral haptic fixation is a minimally invasive technique for cases with absent or inadequate capsule support.
• Learning the Yamane technique presents challenges, particularly threading the trailing haptic.

Purpose of the Study:

• To introduce and evaluate a modified trailing-haptic-first technique.
• To enhance the ease and success rate of the Yamane double-needle intrascleral haptic fixation procedure.
• To address difficulties associated with haptic manipulation during IOL fixation.

Main Methods:

• Modification of the standard Yamane double-needle technique.
• Prioritizing the externalization of the trailing haptic first.
• Utilizing the modified technique for intrascleral IOL fixation.

Main Results:

• The trailing-haptic-first modification simplifies the most challenging step of the Yamane technique.
• This approach reduces the risk of haptic kinking or breakage, even with rigid haptics.
• The modification enhances the overall ease and success of intrascleral IOL fixation.

Conclusions:

• The trailing-haptic-first technique is an effective modification of the Yamane double-needle procedure.
• This modification improves the learning curve and outcomes for intrascleral IOL fixation.
• It offers a more reliable method for IOL fixation in eyes with compromised capsular support.
